MK2s - Z axis is losing steps during print?
My MK2s is having the newest firmware, was working ok but now it has strange problem.
After printer start, SKIRT, BRIM and perimeter are ok, but after starting of infill the nozzle goes lower than it should and it's touching the bed. When I turn by hands Z-rods it's printing 2, 3 layers ok and then again it goes lower and this time it touches already printed part.
I've change Z FEED OVERRIDE (something like that) from 12 to 5 and it was better but still problem occures.
I tried to print the saem GCode on other prusa and it was fine, so it's not a problem with the gcode.
I think that this is a problem with Rambo mini. Mayby voltage is to low or something. Did someone had such problem?
Re: MK2s - Z axis is losing steps during print?
This is not something I have seen mentioned here in the forums before.
The Z motors should be on whilst the printer is on and it should not be possible to easily turn them, so I guess there could be an issue with the firmware.
I suggest you reload the previous firmware to see if the same thing happens. If it does not, then re-download and reload the latest just in case there was a problem.
