Title: Radius to end of arc differs from radius to startline
Post by: Ktown Powder on September 06, 2017, 08:02:46 PM

I am getting the following error when I try and run some DXF files "radius to the end of the arc differs from the radius to the start 2508.  I did a search and most suggest ij mode incremental I did this but it than just moves to a different line with the same error.  I am at a loss of how to fix this issue.
I have attach a copy of the G code I am running and the DXF file and the post processor I am running in sheetcam

thanks in advance for the help.

Mike

Hi Mike,

Your .dxf is fine.

Your Gcode contains both Incremental and Absolute arcs (or at least variations on the Mach3 requirements for arcs).

My guess is that you need to look for a better / more up-to-date post processor to generate your Gcode with an arc format that Mach3 understands.

Where do I find new post processors for sheetcam?

I would start by asking Sheetcam, searching their website or at least posting a question on their forum;  http://forum.sheetcam.com/
