In earlier versions of Marlin G92 doesn’t update the software endstops, so it was unsupported to set coordinates outside these boundaries. Place a piece of paper between the hotend and the print bed. If those adjustments are big enough, after homing all hardware endstops are free. with a single search and very easily. It’s safer to leave Z as 0 here are calibrate this yourself later. Have a question about this project? #define Z_MIN_POS 0. Interrupts are disabled and live_state will never be updated again. Marlin 2.0 introduces an option to maintain a separate default feedrate for G0. This is a requirement for proper working software endstops anyway. In my Configuration.h i have #define Z_MIN_POS 0. adjustment is to properly align Z dual stepper, value is mechanical dependent and will move only one stepper and may not be bigger than bump. Have a question about this project? Endstops.enable(false) This means you can no longer use G92 to move below the bed, for example. Successfully merging a pull request may close this issue. Then it moves to home X, and it tries to move the Z-axis up to Z_HOMING_HEIGHT, which is set from Z_CLEARANCE_BETWEEN_PROBES if that is defined (which it was for me, and it was 5). The patch i meant only corrected to software endstops for G92. note the Z value (i.e 0.7mm) and subtract it from the initial value (2mm-0.7mm). Ender 5 Pro With BLTouch Marlin bugfix-2.0.x config - ender-5-pro.patch My idea is to remove hit_on_purpose call from the position it is now and move it after dual alignment and clear also live_state (when interrupt are enabled and endstop are not always tested). Prepare > Move axis > Move 0.1mm > Move Z; Slowly move the Z axis down until you have the correct first layer gap (paper or thin card method) Note the distance on the display e.g. ... move Z-axis down by steps of 0.1 until it touches the paper. Deltas do have home adjustments , not only for 1 axis of a pair, but 3 adjustments for all 3 of their axes. Don't know what is "DELTA style" since mine is cartesian and I never worked with delta printers. Open the valve for Baricuda 1. privacy statement. Adding the probe-z-offset is no big thing - but finding the right conditions for that to not break something else. @AnHardt I can move z up 50mm, then m119 (all open), and then down 10mm. Likely the error is about here (https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295). Notes. HI Everyone, Im setting up a new printer with Marlin 2.0.x on a Azteeg X5 GT from Panucatt and 32bit Im having a problem with Z homing to max endstop. You could experiment with the same idea to see if it fixes the issue for you. When I run G29 (3 x 3 grid) all 9 points are probed and the LCD tells me that I am at z=0.79. The current position is adjusted to align to the new home offset values. Been using marlin 1.1 but wanted newest auto leveling and other bells and whistles. privacy statement. I'm proceeding to try to understand why planner skip it, Of course M502 and M500 after every time I update firmware. G1 X10.1 Y200.0 Z0.28 F1500.0 E15 ;Draw the first line G1 X10.4 Y200.0 Z0.28 F5000.0 ;Move to side a little G1 X10.4 Y20 Z0.28 F1500.0 E30 ;Draw the second line G92 E0 ;Reset Extruder G1 Z2.0 F3000 ;Move Z Axis up One last thing. For now I guess I have to make sure nothing breaks... @Blue-Marlin will you care to submit a patch for this bug ? ... 1.0.0-beta encoder I2C_POSITION_ENCODERS M860-M869 - I2C Position Encoders. No abort so endstops are not cause. 3 3 0 0 0 0 0. #define NUM_AXIS 4. It seems that it bypass endstops when ENDSTOP_NOISE_FILTER is disabled and Endstop on interrupts are enabled. Delta homes far from bed and can move far from endstops. Since I have #define Z_MIN_POS 0, why is the head moving below 0 ? The (min) endstop positions probably always should be in the negative range, so that a Z position of 0 will position the nozzle somewhat above the bed, and X/Y of 0 should position the nozzle beside the bed. The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). The text was updated successfully, but these errors were encountered: @AnHardt the issue is not during home. $\begingroup$ No, the feedrate for the individual axes is calculated so that the total feedrate is 9000mm/s (e.g. endstops are always enabled but you don't test them, I'll make a PR to solve my problem and I'll do what you will suggest me, so don't post any PR to fix them, @thinkyhead, @AnHardt and @ejtagle I finally discovered what is the real bug but I have some doubt about how to solve it. Skip to # 5 if you're familar with Configuration.h in Marlin. Interrupts promptly may reset hit_state but live_state is set because of at least one micro is pressed. When I run G28 the X & Y home on their respective endstops as before, and Z now moves to the middle of the bed and homes Z using the Z probe. marlin allow negative z, MARLIN FINANCIAL IS NOT LICENSED. Configure BLTouch / 3DTouch in Marlin. Z moves both directions (ok never goes below 0 but after a rise I can lower) Edit: hit_on_purpose is ok and it works. We’ll occasionally send you account related emails. Measure Z heights in a grid, enable leveling compensation. 1) Download install the Arduino IDE and get the latest version of Marlin or your printer MFG available version that has auto-leveling in the Configuration.h file.. 2) Un-zip the Marlin contents into any specially named folder. In CNC G-code G53 is a modifier. Since I have #define Z_MIN_POS 0, why is the head moving below 0 ? EDIT: Re-checked and everything looks ok in this regard. Displayed quote increase and decrease correctly, movement is properly loaded into planner (Planner::_buffer_steps returns true and recalculate() is called) and M119 return all endstop open. Or if you wish, you can use our component search engine Markets.sx, where you can compare prices in different Marketplaces (Amazon, Aliexpress, Banggood, etc.) Since I’m homing to Z-max when G28 is executed by marlin it will home Z first (moving to the endstop, and setting Z to Z_MAX_POS (0 in my case). I'm pretty sure these adjustments to the software endstops are no longer required, so I'm removing them in #3829 (which is mainly to fix an issue where switching extruders could cause movement beyond the software endstops). It is the total number of axis (3) plus the number of extruders (1). My problem is with G38. Instructions are in the comments. Sign in @AnHardt I think I don't understand (it's not the first time I misunderstand you, please be patient). I am using Marlin 1.1.0-RC7. You signed in with another tab or window. Isn't that the min value for Z? The value for X and Y can be quite coarse. Isn't that the min value for Z ? See G54-G59.3 for workspace coordinate system. Isn't that the min value for Z ? Is my understanding of Z_MIN_POS wrong?

M119 will report real input status so when I raise with Z it correctly say "open" but live_state tells another story and will block all "towards home" movements. To set the Z axis home offset on the 3d printer, you will use g-code commands including M206 for the home offset, M500 and M501 for the Marlin Firmware EEPROM feature, and G1 for controlled move to Z axis zero position. When the nozzle starts to get close to the print bed, start to move the piece of paper with your hand at the same time. Successfully merging a pull request may close this issue. Tried to implement latest Marlin on my reprappro with ramps 1.4.

Home is often done approaching bed, endstop are adjusted to be 'hit at pos 0', can't be lower that bed. That's how I have my printer set up, at least. This effectively shifts the coordinate space in the negative direction. Then go to Menu>Prepare>Move Axis>Z-axis>0.1 mm and start to move your hotend down. Marlin also accepts G53 on a line by itself as the command to return to the native workspace. This must also certainly be the case after we lower the nozzle below the "safe height," which is an optional part of G28 homing. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. In Marlin 1.1.0 and up, the physical boundaries are maintained. Is my understanding of Z_MIN_POS wrong ? Set Gap Between Nozzle And Bed Using G-Code, EEPROM & Marlin Firmware Are there other settings than Z_PROBE_OFFSET_FROM_EXTRUDER that affect bed leveling? to your account, Before home: If not please check if you have defined, I have #define min_software_endstops true in Configuration.h. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. It precedes a movement command (or other modifiers) on the same line. Instructions are in the comments. By clicking “Sign up for GitHub”, you agree to our terms of service and (MarlinFirmware:RCBugFix, last update 15/05/2016). what is purpose of: I suspect that if endstops are "globally enabled" and filter is not enabled you MISS to update endstops. On SCARA machines G0 does a fast non-linear move. Axes do home and once both endstops are detected firmware calls validate_homing_move and everything is ok but after that it aligns Z and one of the axis may release the endstop. Already on GitHub? Still goes down to the same value as M851. Simply make this change to the clamp_to_software_endstops function in Marlin_main.cpp: yes, that works.
