Mesh Compensation not moving Z axis Motors

ThePfeiffenator

@phaedrux Yeah I went through an corrected everything you told me to. I had it at Z0.95 and now I have it at Z0.825, but for some reason it is starting way too high now. Very confusing. I just put it to what the G30 S-1 showed after checking it multiple times that way. Measuring right in the middle of the bed.

Does your home Z routine include setting the Z=0 Datum using a single G30?

After you've done the setting of the Z=0 Datum does a command like G90 G1 Z0 result in the nozzle just touching the bed?

Are you trying to print with mesh compensation enabled?

@fcwilt Yeah when I go the G90 G1 Z0 and it does touch the bed. I have G29 S1 in my start gcode, but it wasn't showing on in the dashboard. I turned it on there and we will see what happens.

@fcwilt Still starting way too high for some reason. I am going to try an probe the bed with G29 again to see if that helps.

If it's too high you can adjust the value by the amount you had to baby step back down. The higher the value the closer to the bed. Consider it fine tuning. What the value is and how it was set isn't as important as Z0 being when the nozzle is just touching the bed.

If your height map is wrong it can cause the problem you are seeing if you enable mesh compensation.

Try printing with no mesh compensation.

@fcwilt @Phaedrux Well you guys are amazing, after everything you stepped me through I got it working. I have learned a lot and I really appreciate all the help.

@thepfeiffenator looking at the mesh, i would try some physical leveling too. Either the X is tilted or bed is physically tilted. the less compensation the better. just because it compensates doesn't mean it always should
