Z drive jumping layers help.

Z moving .15 - .20mm up on printing starts at .40 jumps to .50 then .70mm and so on iv used two different slicers and it dose not change.My x and y seem to run fine im lost. Im running 2.02 firmware on the ender 3

;M557 X10 Y10 Z0Your config.g says you have no z endstop (M574 ... Z0) but your z-probe lines are commented out, so how does your printer know how to home z?

@mudcruzr I'm not sure I had to play with this thing just to get it working and not crash on every drive. But everything homes great.

M92 X80.00 Y80.00 Z4000.00 E420.00 ; Set steps per mm
How sure are you that your Z steps is 4000?
-
@phaedrux I'm not I new to the g coding I'm learning on the fly.
-
This will help you calculate the right steps per mm value.
https://www.prusaprinters.org/calculator/#stepspermmlead
I'm gonna guess that it's a 1.8 degree motor, 16 microsteps, and a TR8*8 lead screw that moves 8mm per rotation, which would make your z steps per mm 400 rather than 4000. That would explain why it's moving more than it should be.
-
@phaedrux that was a genarated number that came from the upload I will change and test and also read the article you sent.
-
@waggonburner3 The configurator also has a built in calculator, but you have to actually use it. 4000 is probably the default.

Thank you to everyone for the help I'm getting decent prints now I'll probably hooking up the bltouch in a day or so hope u can handle that by my self but I'm not holding my breath. Lol
