Squished Calibration cube
As they say, a picture is worth a thousand words.... This was supposed to be a calibration cube, but it was supposed to be 20mm in height, but came out 10mm in height.... It printed the whole piece, but just at half the size.
I've been looking around the most common issue reported is z-binding, but my z-axis moves up and down very freely and when it prints, I didn't hear any noise at all which would suggest the screws are not working as intended.
Another article suggest that me extruder steps are mis-calibrated, but I did that calibration 3x on Friday night and updated my M92 E:
M92 X80.00 Y80.00 Z400.00 E138.00
Another article suggest that the Z steps of 400 are too small and need to be 800, I tried that and then I was printing way to close to the bed, after spending all day getting my bed level and getting these squares
So not sure if I do need to adjust my z steps to 800, then re-calibrate the z-offset which I will give that a whirl now to test out a few other options.
@infidelprops Does your Z move 20mm when you request 20mm from DWC?
That would be the first place I would start if i thought my Z was not moving correctly.
Then from that point, reset or note the current distance and move another 30mm.
@paulhew Good suggestion! I did just did that and it moves the exact distance I tell it to.
@infidelprops Brill, that is a start!
Filament type please. I am going to guess, it looks like petg, but probably wrong.
looks like wet filament IMO. or too hot.
@paulhew eSun filament, black PLA... fresh out of the box. Printing at 200 deg, recommended temp for a Microswiss DD hotend.
Do you think it's not a z steps being at 400? I've read other posts that they needed to increase it to 800, which I've done and nowim back at the beginning getting a good first layer. I saved previous settings in case I need to go back

In general if moving 100mm by commanding DWC results in 100mm of movement, then you've probably got it set right! My guess is that you are losing steps mid print. This is probably because your z accel & jerk limits are too high. Are you using z-hop?
Post your config.g and the first 50 lines or so of a print file so we can see what's going on (and if your slicer is overriding things!)
@engikeneer so helpful mate, you're all over my posts!

@paulhew thanks, I will check that article out!
As for an update... After updating my z steps to 800, from the original 400 and re-calibrating 0, levelling, and new mesh, I just finished the second calibration cube and it came out muuuuuuch better!
Still elephant feet and corners to fix, but at least it's printing decent!
