step 1. go to the following link and download the x-carve grbl post processor (right click and save as)
locate your post processor files directory
go to your post processor directory and place the downloaded file there.
set your post processor by clicking post from machine setup, or post under machining job.
select the drop down by current post processor and select “X-carve GRBL”
press edit next to the “current post processor” drop down
select the units you are working in.
generate your nc file and send it out to UGCS or other grbl friendly machine talking to software.
(next step is to be able to use the code with easel) (note, I haven’t tested it yet other than importing the code and make sure it visualizes properly)
these instructions are from Zach_Kaplan (Thanks Zach!)
go to CAM preferences from the machining browser and then select output
arcs as linear segments. (refer to screen shot below). Regenerate
toolpaths before post processing. Toolpath display for arcs is in Dark
Blue & linear motions in Turquoise color.
