Re: Marlin 1.1.8 with BLTouch for i3 Pro B - with T8 Lead Screw Post by JohnDeere630 » Tue Mar 27, 2018 10:41 am I agree with William..also, I once had the 2-pin connector from the BL to the Z-min socket reversed, and it acted similar to what you describe, if memory serves. I noticed that max endstops are forced off if coreXY is enabled, but I need both min and max endstops on the z axis so I can home to max and then use a z-probe to auto bed level. So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity.. I use optical endstops, active high. But on the slower second tap it does not trigger. x_min: TRIGGERED [this endstop is currently connected and bumped to] This time about Motion Configuration.. I'm having a lot of trouble configuring the end stops on my x axis. The firmware can use “software” endstops to keep track of the maximum end, by knowing it’s location relative to 0. February 2019 in Questions & Answers. I use optical endstops, active high. It can not do becouse I do not have end stop switch. Repetier. I use RAMPS electronics, so my MOTHERBOARD definition in Configuration.h is 33. See how each one except for Z_MIN_PIN is set to -1? To avoid this, if you do not have hardware endstops for the G28 command to use, you can disable endstops completely in the firmware. //#define DISABLE_MAX_ENDSTOPS //#define DISABLE_MIN_ENDSTOPS. This will fail after timing out waiting on the Z endstop you don't have. privacy statement. For those of you, like me, who are into 3D printing, here is a quick, and VERY helpful set of marlin gcodes for your Marlin firmware. Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. We’ll occasionally send you account related emails. Hey guys, I’ve been using my mpcnc for a couple of months now, and absolutely love the things I can do with it. The main problem is that after disabling the endstop check, the axis can be moved once and it requires another disabling etc. However if you don’t know the measurements of the probe to the nozzle. Marlin looks pretty solid. Following you will see two picture. A software endstop tells the machine that it should not attempt to travel beyond a limit defined in software. Configuring Endstops on Ramps 1.4 With Marlin Firmware - @section Homing : This is going to be a, hopefully, complete tutorial on configuring endstops on 3D printers build on Ramps 1.4 using Marlin firmware.I am going to use Pronterface/Printrun host program to connect to my printer and issue terminal commands (G-codes). There are many different types of hardware endstops, but there are only two ways for the switch logic to work, either Normally Open (NO) or Normally Closed (NC). The text was updated successfully, but these errors were encountered: ENDSTOPS_ONLY_FOR_HOMING is not an option newer versions of Marlin have. Ender 5 Pro With BLTouch Marlin bugfix-2.0.x config - ender-5-pro.patch #define Y_DIR_PIN 61 Can anyone help with me, how can I switch off in software homeing and end stop ? I don’t use MAX endstops, those are endstops placed at the maximum ends of an axis. plz help thanks Ask Question Asked 4 years, 2 months ago. There is only way to know if the stepper motor direction is correct and it is to try it. Cheers, Wauter When SHOW_CUSTOM_BOOTSCREEN is defined Marlin will first show your // custom boot image and then the default Marlin boot image is shown. Since the home coordinates by convention are 0,0,0, it’s common to only use endstops at the minimum end of an axis. #define Z_MIN_PIN 18 E3D v6, and the 'Orion Module' Piezo probe from precision piezo I have Ender 3 with SKR Mini E3 v1.2 board, which has separate connectors for Z-endstop switch and BLTouch probe. All connected endstops are in TRIGGERED. Notice these lines in mine: This is going to be a, hopefully, complete tutorial on configuring endstops on 3D printers build on Ramps 1.4 using Marlin firmware.. All of the endstop inverting lines are true and my disable max endstops line is commented out. const bool Y_ENDSTOPS_INVERTING = true; I'm tinkering with a coreXZ version of Marlin, based off of the already included coreXY code. Marlin is a popular firmware used for this task but configuring it for auto bed leveling might prove to be a bit of a daunting task for some people. Viewed 8k times 9 $\begingroup$ I have an old Solidoodle 2 that I bought broken from a garage sale that I am converting to use RAMPS 1.4 with Marlin Firmware. z_min: TRIGGERED [currently not connected] Marlin looks pretty solid. Can anyone help with me, how can I switch off in software homeing and end stop ? M119 confirms all endstops function properly and independently, yet when homing each axis, the Y works flawlessly, and X doesn’t trigger either stepper to stop. G92 X0 Y0 Z0 – to set a zero point. z_max: TRIGGERED [this endstop is currently connected and bumped to] #define max_software_endstops false Marlin also has support for software endstops. I noticed when the machine hits an endstops Marlin simply skips any gcode operations in the restricted area and simply continues when it returns to the work bed area. Posted In: 3D Printing. If you don’t have an endstop installed, it will never trigger it and try to go farther than it can, and various bad things can happen, what I call “crashing” the axis. February 2019. Example: When I move Z to position 1.00, Z1.00 becomes the endstop position, and further movement in the negative direction triggers the endstop. I have my end stop set on the right side of my axis and marlin seems to want the end stop to be on the left side. Normally open means the switch closes the circuit when triggered, and in Marlin this seems to be the default in Configuration.h. I prefer to use NC switches that open the circuit when triggered, so I need to invert the logic in Configuration.h for my NC-wired microswitch endstops. Taking a look at relevant settings for the SKR V1.4 and Turbo. My bad, sorry. After all this I decided to simply disable software endstops and work in G53 unrestricted. Posted In: 3D Printing. Aunque en este esquema que he seguido el endsop del eje Z es magnético. Los endstops son todos mecánicos y están en modo NC ya que aparece así en los esquemas de cableado de la Printerboard. It worked before with the factory preset values. y_max: TRIGGERED [currently not connected] If you do disable endstops, it can also be handy to turn off minimum software endstops. Comparing to my marlin config file, all of my endstop pullups are defined even if that position is not used. There is only way to know if the stepper motor direction is correct and it is to try it. Hope this helps.. Disable Maximum End Stops – line 219 //#define DISABLE_MAX_ENDSTOPS. Invert stepper motor direction. The only problem I’m running into, is the soft endstops built into Marlin. edit: The code formatting appears to be broken. For the moment I am configuring the print area and the endstops for a clean homing of each axis. ok. Comments. For our analogy about the room above, if stumbling into the wall is our mechanical endstop then our knowledge about the opposite wall being +5 away would be a software endstop . Below we will be talking about endstops, ... Then disable ENDSTOPPULLUPS, and enable if any of the options within the if disabled section. I am going to use Pronterface/Printrun host program to connect to my printer and issue terminal commands ().That sounded very hairy, but it is just a simple program with a graphical interface. T… How do you configure the pins correctly to have a single x axis and dual Y/Z axis within Marlin (dual endstops on these axis for squaring). Cheers, Wauter You signed in with another tab or window. How to use this Marlin feature of using-endstops-not-only-for-homing without self-blocking the device? In 1.0.2-2 the described behaviour could be caused by always on endstops. Comment out the line to disable max endstops. To be able to move an axis lower than zero, you can set: #define Z_MIN_PIN 18 Invert stepper motor direction. Sign in It seems to be that the Piezo probe responds well to the faster move, but not the slower one. #define min_software_endstops true Using version: 1.0.2-2. After this command endstops will be kept disabled when not homing. I put the firmwate to my Arduino, Ramps 1.4 board, but after start 3d print the machine want to go homeing position. It seems like a deadlock... S1/S2 parameters in G0/G1 does not seem to have an effect in runtime. It also requires re-homing for some commands if the steppers go to sleep. All boards have and E0 driver (some call it something different), and dual firmware capable boards also have an E1 driver, beyond that most boards have breakout pins for more external drivers. Now onto the latest GCode as of Marlin 2.0.5 G0-G1: Linear Move G28 is a command that moves an axis until it triggers an endstop switch placed at the end of the axis. Check with M119. Attempt to use the "auto home" function in the Marlin firmware. Not sure if you got your issue fixed already. The X an Y axis are belt driven pretty much like on a Ultimaker 3D printer, whereas the Z axis is leadscrew driven. Here's what happens when I comment out ENDSTOPS_ONLY_FOR_HOMING: EDIT 1: I just now realized that I'm trying to do it with only 3 endstops - 1 per axis. #define Y_MAX_PIN -1 //15, #define Z_STEP_PIN 46 Disabling/Enabling endstops in Marlin by OhmEye on February 25, 2013 at 3:49 pm. Change the homing direction for the x axis from -1 to 1. Ramps 1.4 Schema. First off, the endstops are completely ignored by Marlin except during the homing process. G0 S1 – disable checking endstops - moving in a direction. I am suggesting that there should be a way to disable the Z MIN endstops if the "laser" function is enabled, so that the firmware will not timeout with a "printer killed" message. Hello, I do not want to use endstop swich in my MPCNC. It can not do becouse I do not have end stop switch. #define X_MIN_PIN -1 //3 Not having Delta, or CoreXY printers included. Configuring Endstops on Ramps 1.4 with Marlin firmware - @section homing Al so JUST made the follow up Motion Configuration on Ramps 1.4 with Marlin firmware @section machine to it. Marlin currently has to have at least one extruder defined, this extruder causes us an issue has we need the driver it is assigned to. Marlin can now adjust that point of reference accordingly. Homing to the MIN endstop is by far the most common method, so G28 moves the axis in the negative direction looking for an endstop and stops when it triggers it and sets the current position to zero. As promised in my last Instructables Configuring Endstops on Ramps 1.4 with Marlin firmware - @section homing the time has now come to make a follow up. Hi, Situation: The endstop point for Z axis keeps tracking its current position. mahesh04. The lines that endable/disable software endstops are in Configuration.h: Look in the Configuration_adv.h sketch for below code. Okay, figured it out. It’s convenient also, since it’s most common to orient printing from 0,0,0 and by using endstops to home to 0,0,0 the nozzle is already where it needs to be to start printing. Sorry if its been asked before but im new to configuring Marlin. My homing position for my MPCNC build is X+/Y-. All of the endstop inverting lines are true and my disable max endstops line is commented out. Suggested Fix. How to use this Marlin feature of using-endstops-not-only-for-homing without self-blocking the device? Or make it go the same speed as the initial tap? These are my end stop settings. A software endstop tells the machine that it should not attempt to travel beyond a limit defined in software. on a Homemade i3 clone. Its a Marlin/Ramps setup. Disable endstops. ... so search for the MIN_SOFTWARE_ENDSTOPS option. Disabling #define ENDSTOPS_ONLY_FOR_HOMING causes that printer wont move after G28. My endstops are located on the top of each arm and are connected on the outer 2 pins on the endstop switch. Anyway, love the machine. I often see confusion by people in IRC about how to disable and enable endstops so that accidentally sending a home command (G28) doesn’t cause their printer to crash an axis past it’s physical range. Marlin endstops. This is going to be a, hopefully, complete tutorial on configuring endstops on 3D printers build on Ramps 1.4 using Marlin firmware.. I usually use optical infrared sensors for my printers, but I wanted to try the BLTouch sensors since none had fallen yet by my hands. Sorry again. Disabling/Enabling endstops in Marlin by OhmEye on February 25, 2013 at 3:49 pm. That is not implemented. Is there are another way to disable endstop check and do manual homing ? * Quick introduction to Endstops and Ramp 1.4 * Connect 2 and 3 pin endstops. avrdude is te vinden in: [Arduino IDE]\hardware\tools\avrbin (eventueel avrdude.conf uit [ArduinoIDE]\hardware\tools\avr\etc ook hierheen kopiëren) Installeren van Marlin. If you need support for a machine with no endstops, it will need to be added as an optional feature. ©2012-2017 OhmEye, James L. Paul | RSS Los endstops son todos mecánicos y están en modo NC ya que aparece así en los esquemas de cableado de la Printerboard. * Get endstop status and configure Marlin firmware @section homing using Pronterface and the newest Arduino IDE. Only have endstops on the mininum end of my axis. Copy link Quote reply Contributor Blue-Marlin commented Dec 15, 2016. // // We suggest for you to take advantage of this new feature and keep the Marlin // boot image unmodified. Thanks in advance. Problems with M666 (Marlin software endstops) Showing 1-21 of 21 messages. By default Marlin only checks physical endstops while homing, and homing moves are blocking, so polling the endstops does not affect performance. Making it stop checking for endstops when calibrating should fix this problem but I can't seem to narrow down where that code is. Aunque en este esquema que he seguido el endsop del eje Z es magnético. * Quick introduction to Endstops and Ramp 1.4 * Connect 2 and 3 pin endstops. Successfully merging a pull request may close this issue. It will help you when you have to diagnose the errors on-screen, and it will help you even more, if you use the command sets through octoprint. #define Z_DIR_PIN 48 Now onto the latest GCode as of Marlin 2.0.5 G0-G1: Linear Move Only have endstops on the mininum end of my axis. ENDSTOPS_ONLY_FOR_HOMING is not an option newer versions of Marlin have. const bool Z_ENDSTOPS_INVERTING = true; When the switch triggers, the position is set to either MIN or MAX for the axis, depending on which direction homing is set to use. After all this I decided to simply disable software endstops and work in G53 unrestricted. The endstops are not actually disabled from Configuration.h, they are defined to the correct pins for your electronics type in the pins.h file. Bij het testen van mijn optical endstops loop ik tegen het probleem aan dat het triggeren van de endstop door Marlin niet wordt gesignaleerd. Also let us know what motherboard you are using. This is undesirable; I would expect an emergency stop. I often see confusion by people in IRC about how to disable and enable endstops so that accidentally sending a home command (G28) doesn’t cause their printer to crash an axis past it’s physical range. It will help you when you have to diagnose the errors on-screen, and it will help you even more, if you use the command sets through octoprint. I likely should have bought a jigsaw years ago, or possibly a scroll saw (but never had space to dedicate to such a machine). I didn’t actually have the endstops mounted and was triggering them with my hand. Once I clicked an endstop I should have kept it closed since the homing expects to keep the switch in a triggered state once it does the step back to the homing position. #define X_ENABLE_PIN 38 I noticed when the machine hits an endstops Marlin simply skips any gcode operations in the restricted area and simply continues when it returns to the work bed area. - Marlin 1.1.9 firmware. So i installed marlin firmware so i could use manual mesh leveling and it all worked flawlessly, except at the end of my print my end gcode has my bed come to far forward and makes a horrible sound because motors are pushing bed further then it can go. Problems with M666 (Marlin software endstops) Brandon H: ... to disable and then re-enable the endstops, and now it works perfectly - M666 does what it should. Seems that only endstop against which the movement is executed is verified and because of pullups on missing endstops in my device it couldnt move after homing. ... Endstops We begin about a ... Next you’ll encounter the “MIN_SOFTWARE_ENDSTOP_Z” option, you’ll need to disable that temporarily by commenting it. Configuration.h. I got it running and printing my first calibration object now. I am going to use Pronterface/Printrun host program to connect to my printer and issue terminal commands ().That sounded very hairy, but it … This is undesirable; I would expect an emergency stop. If I then move Z to position … Disable software endstops. I know this is the same title as #12726, however I rather started a new issue for clarity as I made quite a few tests.It is also hard to decide if this is a [BUG] or [FR] for Marlin, however it is certainly [BUG] for me. Now I load Marlin 1.02 with my modified delta config. All boards have and E0 driver (some call it something different), and dual firmware capable boards also have an E1 driver, beyond that most boards have breakout pins for more external drivers. I don't really think it changes anything here but I'll try to connect missing 3 additional and will confirm results in a moment... EDIT 2: Actually it works correctly when all are connected. (Not connected too of course.) Basically, it doesn’t want to go to -X or -Y. #define Y_MIN_PIN -1 //14 How can i disable the second tap? #define X_MAX_PIN -1 //2, #define Y_STEP_PIN 60 I try to upgrade to a newer version of Marlin, but all the versions I tried don't respond on the endstops. ... #define DISABLE_X false #define DISABLE_Y false #define DISABLE_Z false ... // When you have several endstops in one circuit you need to disable it … This would not be a problem, but I’ve recently started doing multi-layer carves, and for that it’s best to design each layer as a separate SVG, because for some reason Estlcam doesn’t seem to like bringing separate SVG’s in beside each other. I often see confusion by people in IRC about how to disable and enable endstops so that accidentally sending a home command (G28) doesn’t cause their … Moreover I would like to use the auto bed leveling feature in the Marlin … In my example at the top I have all my endstops disabled except for the minimum Z endstop because the only one I had hooked up at the time was Z. It’s much more common to have either all three MIN endstops hooked up or none at all. En pins.h he tenido que cambiar la ubicación del conector del endstop "Y" al del endstop "E" (al parecer es un bug de la placa). Basically, it doesn’t want to go to -X or -Y. I have a somewhat older version made ready for Beta UM by Hendrik Leusink. As shown below. For more information you can visit also the pages I built to show you my new 3d printer Printerina. For those of you, like me, who are into 3D printing, here is a quick, and VERY helpful set of marlin gcodes for your Marlin firmware. I got it running and printing my first calibration object now. Already on GitHub? to your account. If you have software endstops enabled, the axis will not move to a coordinate that it thinks is less than zero, so if it is wrong about it’s actual location it’s possible to crash an axis past it’s travel range. Naturally we want to disable this, so scroll down to the MIN_SOFTWARE_ENDSTOPS option for the Z Axis and disable it. Furthermore disable the option for the MIN_SOFTWARE_ENDSTOP_Z, See below for an example. Uncomment the following lines to disable all max or all min end stops. Figure 1 illustrates the situation. #define X_MIN_PIN -1 //3 It’s very rare to use hardware MAX endstops or all six endstops, using just the three MIN is the most common and convenient arrangement. Endstops will not trigger using Marlin Firmware. Have a question about this project? #define X_MAX_PIN -1 //2, #define Z_MIN_PIN 18 Config: nozzle diameter: 0.3 mm filament: PLA and ABS 1.75 mm The only case where ENDSTOP_INTERRUPTS_FEATURE makes sense is if you also set ENDSTOPS_ALWAYS_ON_DEFAULT. const bool X_ENDSTOPS_INVERTING = true; By clicking “Sign up for GitHub”, you agree to our terms of service and I only changed it to fix my feeding problems with the mk8 chinese single extruder (not enought or no material flow at the nozzle end). #define X_DIR_PIN 55 I know where to go in cura to alter end code but im not exactly sure what to do.
