[BUG] Not Z homing using default configuration for Tronxy X5SA #21339

Closed luiggies closed 3 years ago

luiggies commented 3 years ago

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

I got newest bugfix.2.0.x and newest configuration file for Tronxy X5SA. I flashed printer and I tray homing it but Z axis not homing.

When I call G28 command (or use Auto home from printer's menu):

  1. Bed goes down 10 mm - correct
  2. homing X axis - correct
  3. homing Y axis - correct
  4. extruder goes to center point of the bed (XY move) - correct
  5. should homing Z axis but bed does not move - Z axis not homing - NOT correct.
  6. Bed goes down 10 mm again - correct

Step 5 is very fast. Move from step 4 to 6 is very fast. Step 5 is not observable.

Tronxy X5SA ueses to homing and bed probe the same inductive sensor, so Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN and USE_PROBE_FOR_Z_HOMING are defined

Configuration files: MarlinConfig.zip

Bug Timeline

No response

Expected behavior

Z homing correctly

Actual behavior

  1. Distance between bed and extruder increase to 10 mm
  2. Homing XY correctly
  3. Homing Z - not effect
  4. Distance between bed and extruder increase to 10 mm again.

Steps to Reproduce

Flash Tronxy X5SA newest bugfix-2.0.x and use default configuration file for this printer

Version of Marlin Firmware

Marlin bugfix-2.0.x

Printer model

Tronxy X5SA

BOARD_CHITU3D_V5

rhapsodyv commented 3 years ago

Change to BOARD_CHITU3D_V6

luiggies commented 3 years ago

On the BOARD_CHITU3D_V6 during homing procedure: Bed moves up (good), but soft doesn't listen inductive Z endstop - bed collision with extruder.

BTW: earlier issue with touch screen doesn't appear

rhapsodyv commented 3 years ago

This is exactly the same board I have. You need to use V5 board + this env chitu_v5_gpio_init

luiggies commented 3 years ago

Not good result. I set environment:

[platformio] src_dir = Marlin boards_dir = buildroot/share/PlatformIO/boards default_envs = chitu_v5_gpio_init include_dir = Marlin

and board defined as BOARD_CHITU3D_V5 but result is the same as main ticket description: https://github.com/MarlinFirmware/Marlin/issues/21339#issue-830578612

rhapsodyv commented 3 years ago

Can you try my tronxy branch?

https://github.com/rhapsodyv/Marlin

Because what you described is either a issue with the board version, or a issue with gpio init env, or a hardware issue.

luiggies commented 3 years ago

I tried it and effect is still the same, no correctly Z-homing. Configuration.zip On stock firmware Tronxy homing correctly. any more advice?

Dark-Lancer commented 3 years ago

I had a similar problem on mz xy-2 pro. I checked the endstop states with pronterface M119. After power on my z-sensor was at High until i triggered it 1 time manually. I uncommented the following lines in configuration.h:

1030 #define ENDSTOPPULLUP_ZMIN 1031 #define ENDSTOPPULLUP_ZMIN_PROBE

then it works for me.

luiggies commented 3 years ago

Thank you for help but doesn't work - probably I must to change the mainboard...

rhapsodyv commented 3 years ago

@luiggies did it work for you?

luiggies commented 3 years ago

@rhapsodyv, not for the stock mainboard, I going to change it. I bought SKR v1.3, but I don't change it, yet.

luiggies commented 3 years ago

@rhapsodyv about tronxy mainboard: I noticed that, after starting the printer, Z homing does not work correctly, but if i activate Z probing endstop (example I touch this using some piece of metals) before homing, homing procedure works correctly.

Dark-Lancer commented 3 years ago

@luiggies This is what i mentioned. Check the Endstoppullups in the marlin config. this worked for me.

luiggies commented 3 years ago

@Dark-Lancer I tried your solution but it does not working for me.

Dark-Lancer commented 3 years ago

Hmmm, okay. I have the V6 board. Just as an idea, have you tried to use the pulldown settings in marlin? Maybe the boards have other internal routings. In a forum, someone had the similar error, but also a v6 board :/ https://drucktipps3d.de/forum/topic/tutorial-tronxy-x5sa-von-chitu-auf-marlin/?part=14#postid-135991 In Posting #138 he has written his found solution.

Otherwise i have no ideas left. Wish u luck to get it running.

Dark-Lancer commented 3 years ago

@luiggies I found a second changed in my files which i haven't remembered.

I had to change the assigned pin on my v6 board, but i found no information if it's the same on the v5 board.

In the File: buildroot\share\PlatformIO\variants\marlin_CHITU_F103\wirish\board_setup.cpp i changed the GPIO-PIN for the Zmin/Sensor in Line 103 Original from Rhapsody: GPIOA->regs->BSRR = (1U << PA14); My Change: GPIOA->regs->BSRR = (1U << PG9);
