Z offset is .030 too high after starting print?

TheBasedDoge

Ok, I guess i'll order another real BLTouch. Im using PEI over glass so I dunno if an IR probe will work

In the mean time i still need to figure out the weird offset issue. My layer height is .2 right now, using Cura to slice.

Phaedrux

Can you post the first 50 lines or so of your sliced gcode file?

Do you have an offset configured in cura?

Are you able to use the baby stepping function in the web control to adjust your first layer to print properly?

Have you calibrated the extruder so that you're getting the right amount of extrusion?

TheBasedDoge

No offset configured in cura.
I can use the baby stepping to fix it but I have to click it a ton of times... I've just been manually turning the z motor to adjust the offset.

Can you try updating to the latest 2.05 firmware release?

TheBasedDoge

I did that yesterday actually, no change

@TheBasedDoge said in Z offset is .030 too high after starting print?:

G0 F2215.4 X118.845 Y138.206 Z0.3

are you sure the web gui is report 0.03 and not 0.3 ?

TheBasedDoge

Yes ^

Ok, so I tried PrusaSlic3r and it's not doing it? Where in Cura would be causing this weird issue?

Phaedrux

Can you save a .3mf file from cura and post it somewhere to share it here?

TheBasedDoge

sure, try this

Phaedrux

That .3mf doesn't seem to open at all in Cura.

TheBasedDoge

Huh that's weird.
Try this one: https://www.dropbox.com/s/enx9kfmvuy7e1vu/CFFFP_test.3mf?dl=0

I just tested and it opened on my cura 4.4.1

Phaedrux

That one worked.

I still don't see anything that would add an additional 0.03 offset.
