Hi themurr,

Glad to hear you love PixelCNC :)

Are you setting the project's machine origin to the same place you're zeroing your machine at relative to the workpiece?

There could sometimes also be work offsets that aren't being cleared, I've experienced that a few times. If you're absolutely sure your machine origin is set where it should be relative to where you're zeroing your machine, you can clear work offsets by adding a G53 command at the top of a G-code file and see if that fixes the situation.

Charlie,

Thank you for responding so fast! I preface this by saying , that I'm still newish at this. I will explain my workflow, and maybe you have an insight into what I'm doing wrong. So, I have a photo I want to carve a half tone of in to a piece of wood. I feel like the thickness of the wood itself is arbitrary since I am just essentially making marks. I set the canvas properties to 5x7 with a Z size of .040" and a Z origin of 0.00. I import an image same size as the canvas , invert it, set the Z Size to .040" and the Z origin at 0.00. Z fill for both is set at zero. I set up a Spiral Carving operation with a 60 degree V-bit set at .06" step over, min depth of 0.00 and max depth of .040" and .1" rapid height. When I simulate the operation it looks money. output the gcode - this is the first few lines

G0 Z0.14000

G0 X-0.05011 Y2.03000

G1 Z0.01037 F60.0

G1 X-0.04999 Y2.03097 Z0.00935 F60.0

It seems like its adding the thickness of the canvas to the rapid height? Anyway, when I go to machine the image, it seems like the bit is hovering by about that much (.14") over the work piece. I have an xcarve, and I use the metal puck to set the workpiece zero. So, you're saying that if I add just the G53 command at the beginning of my code it will negate the "G0 Z0.14000"? I really appreciate your help with this!

Kind regards,

Michael

When you zero your machine - set it's 0,0,0 coordinate, it sounds like you're setting your Z=0 to the top surface of your material, but in PixelCNC you're saying it's the bottom of the canvas. Try changing your canvas Z origin to 100% (or 0.04") which is the top of your canvas, and keep zeroing your machine the same way you already are. The G0 Z0.14 means that it's .14" above wherever you set your machines Z=0 at. If you want to not have to worry about the thickness of the material then you want to set your project's canvas Z origin to 100%, so that you can set the top of your workpiece as your Z=0. That's the strategy I always go with because it just makes everything much simpler.

Let me know how it goes!

Charlie,

That was totally the issue! It's working perfectly now. Thank you so much for your amazing customer service. Again, I love this software, it's a real game changer for me and my artwork.

Warm regards,
