Post Processor Problem

Post by BuchanansAus »

Hello,

Trying to engrave a 2D logo using our new acorn controller.
Created the code in CAMBAM using cambam's centroid postprocessor.

However i am getting circles in the toolpath on some of the radiuses.

I have tried changing the acr centre mode to no avail.

Attached is a picture of the toolpath. Any ideas what could be causing this please?

Perhaps attach your g-code for people to check it out. It reminds me of an issue I used to have with a ShopBot controller many years ago, and it was due to the code not being carried out with enough decimal places. Three or four decimal places would cause arc loops, but six would fix it.

Might want to take a look at the formatting of G2 G3 arcs in the post processor.
