I used to surface stock by adding small values to the Z in mach4’s dro to step down in between passes until the surface was level. It is not immediately clear how to do this quickly in Centroid. What is the proper procedure on this? @Eric Mach4, current positions editable by clicking on the number…

Yes, but the point is that I don’t want to use it between every pass. Just once at the start. I think I found the solution: [Untitled] I can just add the new Z value here. Lots to learn with this new software!

[image] Eric: G53 Z0 will move the machine Just to clarify here, the G53 command isn’t a move command. It just says “for this command, use machine coordinates instead of work coordinates.” You must ALSO specify a move command (like G0 or G1). That command might have been specified already,…

Hmmm… If you do add a G0, like G53 G0 Z0, would it still work? A bit of searching shows that some interpreters do it one way, and others (like linuxcnc) do it the other way. (so much for “standards” :wink:

[image] djdelorie: (so much for “standards” :wink: There are no standards in G code :upside_down_face: It looks like you can use a G0 command preceeding a G53, but there’s no need to.

Can you send me a g-code file for a simple cut? This way I can determine if it’s my code or something else. I have tested g-code from Fusion, Easel and V-carve Pro with all of them giving me the error.

[image] Aces4days: “z travel exceeded” e Your program looks fine. I’d gather that you get "“z travel exceeded” if your tool hasn’t been measured. But if you don’t change it, and re-run the program, you don’t get the error. Right? Corbin

When I run programs with multiple tools, I often get a Z error statement when CNC12 initializes the g-code. It hasn’t been an issue. I think it is just due to the next tool in the program being unmeasured.

[image] greg.obj: I think it is just due to the next tool in the program being unmeasured. That’s exactly what that is. Centroid can’t predict the future length of a tool. If you actually did get to a cut that would go outside the bounds that the machine is set to go it wouldn’t actually do i…
