Fusion 360 - Program ending early

Mostly Printed CNC - MPCNC Troubleshooting
#1

I’m pretty baffled by this and looking for help. I’ve imported the dxf for the back panel of the MP3DP into Fusion 360 and created a pocket and contour operation. After a few lines of the contour operation, the operation “completes” and I get a G2/G3 out of machine limits error. I’ve attached a photo of the exact point the program stops and the GCode file I’m using. My machine limits are 0,0,-50 and 500,500,100, so I’m not sure where the conflict is.

Any help would be greatly appreciated. Thanks!

Marlin? Grbl?

 

I would try to disable soft limits first by typing M211 S0 in the MDI. That’s a zero not a letter “o”

Do you have the exact line it stops on? I think it’s something to do with the Z limits you have set up but I can’t articulate why.

 

Edit: wait where is your origin set? Because on the first operation your Z never goes below 0 (like you have it set on the spoilboard) but on the second (the contour) it immediately goes below 0 (like you have it on the top surface of the part)

Ah, good news! I checked the GCode over again and noticed it goes into X-1 and Y-1, which I hadn’t accounted for. Cue the program ending when it hits the 0 limit. Adjusting my axis minima to -50 allowed it to continue perfectly.

Do you have “Tool Orientation” checked inside operation “Face2”? Tool orientation is intended for multi-axis machining and our posts don’t support that AFAIK.
