![]() ![]() As such, getting the initial torch height (ITH) set BEFORE EACH CUT (M3 command), and performing a Z retract AFTER EACH CUT (M5) is all that should be needed to round out LB support of plasma cutting. , which as the post describes manages the torch height once cutting has commenced, independent from gcode gen and send sw such as LB. What I believe is lacking from LB right now, for the plasma cutter w/THC use case, is the “per-cut focus touch-off” (PCFTO) feature that Oz mentions in his reply to above ref. So I’d like to request that LB consider what may be a simple feature to fully enable plasma use case when torch height control (THC) is available in the CNC plasma machine. ![]() But for artsie/craftie laser work, I like LB quick and easy. The system I’m building recommends CAD/CAM such as Fusion360 w/UGS, and I’ll use that just as I do now when routing on my current CNC when engineering drawings are required for the cut. I currently use LB on another router/laser CNC machine, and I like LB in many ways that I see will be beneficial and efficient when controlling and cutting on the new plasma machine. I’m in the process now of building a CNC plasma cutter, I expect to be ready to burn in about 2 weeks. The above referenced post does a nice work sorting out the plasma cutter use case for LB.
