Configure BLTouch / 3DTouch in Marlin. * For other boards you may need to define FIL_RUNOUT_PIN. Benefits are that the firmware software endstop is enforced on printer restart. In my printerina I have also a Zmin endstop connected because I have a Zprobe configuration. Have you been able to implement endstops similar to the way they work in Marlin? 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. This is undesirable; I would expect an emergency stop. This enabled ENDSTOPS_ONLY_FOR_HOMING // In combination with G92 command marlin can be used to manually do an X,Y,Z axis homing and mill down an part Moreover I would like to use the auto bed leveling feature in the Marlin firmware. My first RepRap, a Prusa with Gen6 controller running the same software, works perfectly with no homing issues, and retains the use of the Min soft-stop. Marlin_software_endstops_enabled+G54fix.zip, https://github.com/synthetos/g2/wiki/Gcode-Coordinate-Offsets, https://github.com/MarlinFirmware/Marlin/issues/14734, https://github.com/MarlinFirmware/Marlin/issues/14743, https://github.com/cncjs/cncjs/issues/514, https://www.v1engineering.com/forum/topic/dual-endstops/. The second attempt completed successfully. Beginning with Marlin v1.1.9 and v2.0 the software measures against endstop noise are improved and exposed as a setting. My … Within Marlin 2 there is a section for a software based minimum end stop. Arduino IDE 1.0.5 Nous aurons besoin de l’éditeur arduino pour modifier et installer le firmware … This will fail after timing out waiting on the Z endstop you don't have. To disable software end-stops, find the above lines of code in Marlin Firmware Configuration.h file and set each line to false as shown. 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. https://github.com/MarlinFirmware/Marlin/issues/14743. Prior versions already implemented filtering that is permanently active. I tried to leave the description open in order to describe generically how to configure enstops so to be used by anyone building a 3d printer, If you need additional specific information about this topic or if you want to look it personally please write an email, How to identify Pins we will connect on Ramps 1.4. However when I comment out #define ENDSTOPS_ONLY_FOR_HOMING - this causes that printer won't move after G28, since all home endstops are activated and that prevents any further movements. I do however have Xmin and Ymin enabled in Config.h. * - X and Y only apply to Cartesian robots. Don’t go beyond the maximum limit. After all this I decided to simply disable software endstops and work in G53 unrestricted. There is a thread about this in the repetier forum, but i think you should be able to find the place. If you want ALWAYS_CHECK_ENDSTOPS to work also on z endstop look into Repetier.pde bresenham_step and move the z endstop test inside the if condition. Spot drill hole pattern in spoilboard. After all this I decided to simply disable software endstops and work in G53 unrestricted. 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. I'm tinkering with a coreXZ version of Marlin, based off of the already included coreXY code. i try some test but without success. However, Marlin does not recognize G10 L20 P1 X0 Y0 Z0 commands unfortunately. Even if you disable ALWAYS_CHECK_ENDSTOPS checks should still occur duringhoming, hence the flag. G53 is the machine coordinate system. * - Individual axes can be disabled, if desired. Place the spindle in the bottom left corner as if Xmin and Ymin limit switches endstops had been triggered. G54 ; Switch to 1st work offset coordinate system. It is now time to plot the obligatory MPCNC crown test pattern with a pen holder and pen. You can use keypad jogging. I still have a problem, my Z motors are not moving correctly in Marlin 2.0 I could make them work with Marlin 1.9.x it was homing perfectly, when I changed the extruder number and the thermistor everything stopped working, I had to switch all of the endstops, I am thinking about switching to repetier and use it without endstops as it is becoming impossible to make them work As I explained in the previous article of Configure Marlin 2.0.3 from scratch, to activate the options you simply have to uncomment them. Xmin and Ymin enstop positions also work correctly and are relative to the G53 machine coordinate system origin as they should. I applied Peter Hercek's M666 patch, the same one merged in Marlin, on top of my branch … #define max_software_endstops true. 2. ... #define min_software_endstops false The lastest is the same that "M211 S0" command I think, but I hardcoded in firmware. Endstops As this is defined in Z_MIN_POS 0. A software endstop tells the machine that it should not attempt to travel beyond a limit defined in software. More detailed information here: Which I am relatively new with. Hi, I have allready tried, but I did not find a solution. Lets say the height for the Z-Axis is 0mm. This is undesirable; I would expect an emergency stop. G90 ; absolute coords or G91; relative coords. Do not move spindle by hand (!) When I power up the machine with the spindle located in the center of the spoilboard, this effectively becomes X0 Y0 Z0 and I cannot move to the left or to the bottom from here as that is considered outside of the bed area. Firmware Télécharger le firmware directement iciet décompresser le dossier. Marlin firmware does not support G10 L20 P1 X0 Y0 commands. 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. threaded inserts. >>> https://www.v1engineering.com/forum/topic/dual-endstops/ Marlin Configuration - Micromake Delta . #define min_software_endstops false // If true, axis won't move to coordinates less than HOME_POS. Because this is defined in Z_MIN_POS as 0. Forum List Message List New Topic. I tested this and it works properly. 1. Now disable the option for the MIN_SOFTWARE_ENDSTOP_Z. Manually drill through using suitable bit. https://github.com/cncjs/cncjs/issues/514. This is the actual result of the very first time the machine was used to plot a file. I am going to use Pronterface/Printrun host program to connect to my printer and issue terminal commands ().That sounded very hairy, but it … Unfortunately I still can’t move to negative Z, even with this off. I didn't know this myself..... Top. Printer area. Disable software endstops. * * RAMPS-based boards use SERVO3_PIN. Attempt to use the "auto home" function in the Marlin firmware. Could explain me where the issue with this evil endstop ? However when I comment out #define ENDSTOPS_ONLY_FOR_HOMING - this causes that printer won't move after G28, since all home endstops are activated and that prevents any further movements. So as a first attempt I created a drill grid for a 920x920mm spoilboard consisting of a 9 x 9 points grid with 100mm spacing and a 60mm edge perimeter: I then generated a center drilling toolpath and loaded the MPCNC Fusion360 Post processor to generate Gcode: I had to leave some holes out as the machine could not reach. Even if I am in G54 I cannot go past Xmin and Ymin, which is a nice safety feature. I am setting up a X-min, Y-min, Z-max 3-endstop configuration, but have been unable to get the desired behavior, instead getting one of … The travel distance is not calibrated yet and the practical distance will be different than the calculated distance. Make sure to set the step size to a safe value before pressing Arrow Keys or Page Up / Page Down. Spot drill hole pattern in CNC bed to hold down spoilboard. When generating Gcode in Fusion360 select “Setup” and select ‘Use Personal Posts’ from the drop down list. Lets say the height for the Z-Axis is 0mm. It would stop at 0mm and not go any lower. https://github.com/synthetos/g2/wiki/Gcode-Coordinate-Offsets. When I ran the Gcode on the machine I realized my machine does not do absolute negative machine coordinates. Log In Create A New Profile. #define min_software_endstops false ; to allow negative Z movement // Set these appropriately for the size of your printer // These are set for my Cobblebot basic #define LEFT_PROBE_BED_POSITION 15 #define RIGHT_PROBE_BED_POSITION 250 #define FRONT_PROBE_BED_POSITION 20 #define BACK_PROBE_BED_POSITION 250 function gtag() { dataLayer.push(arguments); } ... "M211 S0" => Disable Software endstops Do your calibration, after sending M211 S0, you will be able to select Move Z-Axis => 0.1mm and move negative. Z axis min/max endstop. #define MIN_SOFTWARE_ENDSTOPS #if ENABLED(MIN_SOFTWARE_ENDSTOPS) #define MIN_SOFTWARE_ENDSTOP_X #define MIN_SOFTWARE_ENDSTOP_Y //#define MIN_SOFTWARE_ENDSTOP_Z #endif. I had a Z probe installed but the wires came out of the header so I am trying to use software endstops, but any time I G28 the nozzle will always ram into the bed. The one disadvantage is that CNC.js Axes widget does not display work (offset) coordinates. I discovered using G55 (2nd work offset coordinate system) works fine however. After all this I decided to simply disable software endstops and work in G53 unrestricted. 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). GitHub Gist: instantly share code, notes, and snippets. Emergency stop ideas In the stepper.cpp file, however, I noticed endstops are tested like this: Insert (glue?) Marlin. Marlin 2.0 Config for Ender 3 with E3D Hemera and BLTouch (SD Disabled) - Configuration.h ... // #define SOFT_ENDSTOPS_MENU_ITEM // Enable/Disable software endstops from the LCD # … This will allow me to simply move the spindle by hand to the origin of choice and power up the logic board from there. ... so search for the MIN_SOFTWARE_ENDSTOPS option. The resulting code looks as follows: spoilboard.gcode. My issue revolved around getting the axes to behave properly with the endstops. * - Individual axes can be disabled, if desired. The first extruder gets assigned to driver E0. Here we can tell the firmware what the limits are of the travel zones. window.dataLayer = window.dataLayer || []; Don’t go beyond the maximum limit. So now I need to use software endstops. * - Use 'M211' to set software endstops on/off or report current state */ #define max_software_endstops true. G10 L20 P1 X0 Y0 Z0 is identical to executing G54 followed by G92 X0 Y0 Z0 and then returning to the original coordinate system. I have min_software_endstops=true in my Marlin configuration for safety, but according to the docs it should be possible to disable that in software using M211. I attach the concerned part of my configuration.h file. A more detailed explanation can be found here: 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). #define max_software_endstops true // If true, axis won't move to coordinates greater than the defined lengths below. #define min_software_endstops true. 3. Naturally we want to disable this, so scroll down to the … "M211 S1" => Enable Software endstops. I found the way the limit switches are implemented (machine full stop) to be overly dramatic for my use case. This would be my machine coordinates origin X0 Y0 Z0 when I power up the machine and gives me positive machine coordinates for all my moves from here. Problems with M666 (Marlin software endstops) Showing 1-21 of 21 messages. Note that CNC.js sends a G10 L20 P1 X0 Y0 to zero the work coordinates. // Allow M211 command to disable software endstops temporarly. T… You cannot set a new origin in G54 without it also affecting the origin of G53 and vice versa (! I flashed Ryans dual firmware to the board but this is for the MPCNC more so than the Lowrider. For the moment I am configuring the print area and the endstops for a clean homing of each axis. Here we can tell the firmware what the limits are of the travel zones. Power up MPCNC machine with spindle in lower left corner. Home > Reprappers > Topic Advanced. // @section machine // Travel limits after homing (units are in mm) #define X_MIN_POS 0 #define Y_MIN_POS 0 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. I want to be able to adjust my z-offset with software, but I can’t get my machine to descend below the endstop. /** * Software Endstops * * - Prevent moves outside the set machine bounds. Marlin for the noob ( endstops issues) Posted by Print37 .  Printer area. So you only need it for calibration. (MKS Gen L v1.0 + color/touch LCD)  -> LCD = extra CPU load + distraction ?) My homing position for my MPCNC build is X+/Y-. Disable software endstops. G0 X270 Y340 ; move to center of spoil board. # define MIN_SOFTWARE_ENDSTOPS // If enabled, axes won't move above MAX_POS in response to movement commands. #define max_software_endstops true // If true, axis won't move to coordinates greater than the defined lengths below. gtag('config', 'UA-88833721-4'); In these pages I will show you how I configured endstops for my printerina 3d Printer. With software endstops enabled, moves will be clipped to the physical boundaries from … (#define min_software_endstops = false) will allow me to home, however, you lose the use of the soft-stop to prevent accidental ramming of the carriage pass home and displace the home switch. Firmware is the program or software “embedded/burned” into the electronics board, this is what translates the gcode into motion in the stepper motors. ), I have reported this as a bug on the Marlin github page issue tracker: 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. Marlin also has support for software endstops. I am using Marlin Firmware. This means absolute negative machine coordinates are not allowed; you cannot move beyond the lower left corner. 2. #define MIN_SOFTWARE_ENDSTOPS #if ENABLED(MIN_SOFTWARE_ENDSTOPS) #define MIN_SOFTWARE_ENDSTOP_X * - Use 'M211' to set software endstops on/off or report current state */ // Min software endstops constrain movement within minimum coordinate bounds #define MIN_SOFTWARE_ENDSTOPS #if ENABLED(MIN_SOFTWARE_ENDSTOPS) … Marlin does support G54 – G59 work coordinate systems: CNC_Coordinate_Systems is enabled in my [Configuration_adv.h]. # define MAX_SOFTWARE_ENDSTOPS /* * * Filament Runout Sensor * A mechanical or opto endstop is used to check for the presence of filament. Carte : RAMPS 1.4 Firmware : Marlin 1.0.0 i need help to configure my fireware marlin to use optical endstop. 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. This is because Marlin only outputs a single set of coordinates at a time. Multimeter Z probe. Locked. The x-axis and the y-axis move the right direction also homing direction is ok, but the endstop does not stop the bed or the x-carriage. //#define DISABLE_MAX_ENDSTOPS //#define DISABLE_MIN_ENDSTOPS Upload the firmware and redo the test in Pronterface. However, I can now add software issues to my list of "things to hate this machine for". I have lodged a feature request with the great developer community of Marlin: #define max_software_endstops true // If true, axis won't move to coordinates greater than the defined lengths below. I do not have limit switches installed as of yet. Software / Firmware. Repetier-Software - the home of … For instance lets say the height for the Z-Axis is 0mm, it would stop at 0mm and not go any lower. As soon as you have Xmin and Ymin enabled, the machine will force you to stay within the bed area. … * - X and Y only apply to Cartesian robots. threaded inserts. Pastebin.com is the number one paste tool since 2002. Marlin 2.0 Config for Ender 3 with E3D Hemera and BLTouch (SD Disabled) - Configuration.h. 3. Physically plugging the steppers into the Rambo 1.4 is easy and already laid out in other post. Naturally we want to disable this, so scroll down to the MIN_SOFTWARE_ENDSTOPS option for the Z Axis. Dual endstop micro switch calibration using Xmax and Ymax: In Marlin 2 there is a section for a software minimum end stop. "M211 S0" => Disable Software endstops Do your calibration, after sending M211 S0, you will be able to select Move Z-Axis => 0.1mm and move negative. I had to restart the operation as the pen tip was a fraction too close to the surface and started dragging. Problems with M666 (Marlin software endstops) Brandon H: 11/6/13 11:32 PM: For awhile I had been using screw-adjusted endstops, which were great until one of the screws' thread stripped. Description. * - Use ‘M211’ to set software endstops on/off or report current state */ // Min software endstops constrain movement within minimum coordinate bounds #define MIN_SOFTWARE_ENDSTOPS #if ENABLED(MIN_SOFTWARE_ENDSTOPS) #define MIN_SOFTWARE_ENDSTOP_X #define MIN_SOFTWARE_ENDSTOP_Y #define MIN_SOFTWARE_ENDSTOP_Z #endif #define min_software_endstops false #define max_software_endstops false. Optionally enable/disable software endstops, then report the current state. Software end-stops are enabled by default. However when levelling the bed, this causes an issue where the probe or nozzle can not be lowered enough.
