Old issues addressed in any recent releases?

Been away for a while and my last eligible update was in February last year. I’d gladly buy an upgrade to all my licenses if the following two can be addressed.

This one is a couple years old now if you count the initial post referenced within. Basically I would like to be able to create a seamless 360deg raster on various diameter objects. I have a chuck style rotary and can do vectors perfectly. Rasters, not so much.

Seamless rotary wrap engrave

Well it’s a 3/4’ dowel from the hardware store. It’s not going to have aerospace tolerances. Here is the thing. The issue also comes up when we are engraving borosilicate and quartz crystal tubing, which are dimensionally very consistent. The gap were seeing shows up in the G-code Lightburn generates. We do not have this issue with code generated from Laserweb, but that has other limitations. It’s a bug in Lightburn, unfortunately for us it’s a low priority.

The cutting speed on arcs on the rotary is not desired behavior. The cutting speed slows down to a crawl when the more A-axis dominant the move is. Simply have the speed set to 1 speed throughout the whole move makes this work better.

Slow circles and arc cutting with rotary

When cutting arcs or circles using the rotary. Lightburn produces G-code that slows the speed to a crawl proportionally depending on the amount of A axis movement vs X axis. I’ll post the gcode at the end. It does not exhibit this behavior when cutting rectangles or straight lines. Basically it ends up over melting the ends of my holes I am trying to cut. Lightburn is current and this is a custom machine using GRBL-LPC. Gcode below ; LightBurn 0.9.14 ; GRBL-LPC device profile,…
