Z Axis seems Weirdly Slow (0.01 mm a sec)


So I’ve been cutting some things for a couple months and left it dormant for a month or 2 while waiting for a good time to do a plywood trip. So I fired it back up and noticed the Zaxis running a lot slower than I remember. Nothing in my tool chain has changed I don’t think.

The Zaxis moves imperceptdly slow at almost 0.01 mm per second.

When using the direct zaxis control in ground control it moves at a much more reasonable speed where you can visually see it move. Probably at about 1mm a second.

Is the cutting zaxis speed really that slow and I’ve just haven’t been paying attention? I swear I have vague memories of seeing the zaxis move the same speed as it would as the zaxis control panel, but it’s been enough time I don’t remember anymore.

Any thoughts would be great!


Do you have a feedrate for Z in your gcode?


Yep, I use kir:moto out of onshape, usually it gives me the followin as it did on the code i’m trying to run

M6 T1
G0 X417.476 Y-359.2213 Z4.0
G1 Z-6.35 F800
G1 X432.1703 Y-351.0724
G1 X446.3131 Y-346.5507
G1 X457.1819 Y-343.7558
G1 X471.7225 Y-336.9188
G1 Y-334.8459
G1 X487.2283 Y-325.2766
G1 X491.0319
G1 X497.6792 Y-326.872
G1 X506.5615 Y-333.2672
G1 X509.8445 Y-341.8487


So it’s not in the g-code, F800 is fast. You are in mm with your file?
Did you upload the latest release firmware and using same version GC?


Ahh good call, i’m still on 1.16v good thought! thanks!


Let us know how it goes.


Thanks!!! It works now, the feed rate in general seems faster now too. I should’ve remembered, when in doubt always update…
