SheetCAM Gcode will not run in Mach3
« on: January 30, 2008, 03:21:48 PM »
Hi Guys,

I recently started using SheetCAM, and I have generated some G code using it. However, for reasons that I can't seem to figure out, it will not run on my machine under Mach3 Mill, while G code generated with Lazy Cam runs just fine. I selected the Mach2 post processer in SheetCAM because there is no available option for Mach3. I suppose that the problem lies in the post processor, but I am not familiar enough with G Code to see what it is. I have attached one of each of the files. the inner plate file was made by Lazy Cam and it works; the anti-rotation collar was made with SheetCAM and it does not work. I would really appreciate it if any experts out there could tell me what it wrong.

When you say it doesnt work, what do you mean as it seems to run fine here.

You don't give a lot away about what's actually happening - "it doesn't work" is a little vague  ;D

On my system where I have IJ mode set to absolute by default I get error: "Radius to end of arc differs from radius to startLine 78". I checked the I J arguments on line 780 (Mach allways misses the last digit off a line number for some reason) and sure enough they're incremental. Switching mode to IJ inc the error moves on to: "Process: Outside offset outside. Mill/Router. 0.25 inch diameter. 0.75 inch Deep" which means nothing to me - perhaps someone else can take it from here.

Sorry for being vague. I don't know why, but when I reloaded it today, it ran fine. Operator error, I would say. Thanks for the help. What I noticed when I was having the problem is that the code would load into the code window, but the graphic would not appear and when I started the cycle, I got no response from the machine, even though it was moving through the code.
