I’m testing out a 3d renderer and need a gcode file that has a z-axis movement during an arc movement. I’m not sure how to make one (it doesn’t look like makercam supports it). Can someone post a test file or otherwise make it available to me? I can give you my email address if you have one.

Thanks!

Hey,

I think you could get that by using MeshCAM. They give a 15 day trial license.

Thank you

If you’re using firmware from the current Master branch (after PR#477), you can add a Z term to any G2/G3 line to see z axis coordinated movement. Here’s a simple one with two circles that I used to test that PR (G3 goes CCW, G2 goes CW):  
[edit - I added lines to give additional depth to the circles]

```auto
G20 G90
G0 X0 Y0 Z0
G3 X.0 Y0.001 Z-0.5 I1.0 J0.0 F100
G3 X.0 Y0.001 Z-1.05 I1.0 J0.0 F100
G3 X.0 Y0.001 Z-1.5 I1.0 J0.0 F100
G0 X0 Y0
G2 X.0 Y0.001 Z-1.0 I-1.0 J0.0 F100
G2 X.0 Y0.001 Z-0.5 I-1.0 J0.0 F100
G2 X.0 Y0.001 Z0.0 I-1.0 J0.0 F100
G0 X0 Y0

This look correct?

I hope this gets into the default docker image soon 😁.  
I haven’t mastered the process of rolling my own, and the default docker image is sort of hard-coded into webMCP’s update button, isn’t it?  
While I’m wishing, how about making either the ‘Running’ or ‘Responsive’ button trigger an action to open localhost:5000?

I’m back in town tomorrow. But I’ve been thinking of how to do a system that does an auto build of the dockers.

I think I can add the auto load… I’ll look into it.
