Z Axis seems Weirdly Slow (0.01 mm a sec)


#1

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?

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?

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