z- axis motor.. parameters

bojan

Hi huys
After succesful installation of the firmware in mu newly built 3D printer, I noticed a problem with z-axis: no matter what number for steps/mm I place in configuration.h,  the result is alwas the same, and wrong, while other two  (x, y) motors behave OK (from host I tell it to move 50mm, it moves 50mm..).
I wander if this was a recent bug in firmware, not reported yet?
Thanks in advance!

No bug. Z axis is tricky if it is rod based. Can not go so fast and stalls easily. Try max. feedrate 3 mm/s and acceleration 50mm/s^2. And checkif it is greased well. If it then works you can start finding the limit.

If you have eeprom enable, change values in eeprom to have an effect.

Yep... before I read your reply, I actually tried with version 0.91 and it started to behave OK (missing steps). Slower speed and lower acceleration sorted the problem... so I am still wandering about the bugs :-)
