Test engraving using grbl-LPC. 150mm diameter. Briwax rustic pine finish. Not much difference in engraving quality as compared to the one done by smoothieware. Laser motion is super smooth over USB serial, a good reason to convert to grbl-LPC.
@E_Caswell I only confirmed that the rotary moves with the jog buttons. Kinda ran out of round stock to laser. Need to get some wood dowels or similar.
@Kelly_Burns I originally found this file on Facebook. However was told it is copyrighted. You may be able to still find it around but I can’t repost again.
