Great to hear that Easel support is in the works! I look forward to trying v1.44a soon.
I have done some reading about using other G-code senders with Carvey before, but have thus far been reluctant to try it because A) it voids the warranty (which is nearing its end anyway) and B) some forum posts indicated that, at least for Universal G-Code Sender, a code change + custom build was necessary because the Carvey identifies itself as "gCarvin" rather than "grbl". Candle may not have this issue, so if I get more adventurous, I'll see if I can get Candle + Carvey to work together, but I may just wait until 1.44 for now...

Yep - so far Easel has handled all of the 3D carving toolpaths I've thrown at it from Fusion 360 with no major issues. It doesn't have simulation/3d rendering of the workpiece but it shows the toolpaths and seems to work fine as a G-code sender which is all I really need it for. However, I don't like the idea of being locked into it long-term, so I'll be looking for another sender eventually.
Thanks again for your help.
