I found it... Editing configuration.h doesn't help anyway. But I found another way and that's sending commands directly as gcode. I used M92 Z400.000 and then M500 to save it. Original value was 200.000. Sending was made by Cura's monitor. And now it moves as it should. I will try out to print something. Anyway it is thank to gr5's older post regarding calibration: https://community.ultimaker.com/topic/18879-how-to-calibrate-xy-and-z-steps/?do=findComment&comment=231037 So thank you gr5! 🙂

Thanks gr5, I've already uploaded Marlin with remapped pins and Z ax finally moves. Unfortunately there is another trouble with microstepping. Original Z ax driver is set to 1/8 microsteps but E2 driver is 1/16. I've changed steps per unit value from 200 to 400 in configuration.h but that has no effect – UM2 still uses just half of Z ax dimension. Have you or anyone else been facing the same issue? Thank you very much, I appreciate your help.

Hi guys, the same happened to me, just with the Z-axis. I've changed the pin map but I cant find the way to create hex file or any other way how to put new firmware into the printer. Any suggestion, please? Thank you.Hi guys, the same happened to me, just with the Z-axis.

Hi guys, had someone of you some issue with Z-axis movement on UM2? My one doesnt move in normal way, its just randomly moving and just in down direction. When I try to move screw manually it goes pretty easy so it seems to be an electrical issue. I ve measured stepper resistance and both coils have the same resistance. When I try to swap stepper from Y-axis to the Z-axis driver it does the same weird movement. The pcb around all drivers has an yellow shade, probably caused by high temperatures. Does it mean I have broken complete board?? 😕Thank you very much for any advice. Happy printing 😉 And I forget to say I got the ER06 error but the limit switch is well connected and also function is ok.
