I almost messaged you last night, I was going through the LR2 thread and saw your nice parts and wondered what happened. Now I know and it was worth the wait!
I have a tiny emglo compressor, does it take much air to keep the plasma fed?
Thank you.
The nameplate says it takes ~4.4scfm at 60psi
I have my dad’s old John Deere compressor that says it makes 3.5scfm at 60psi and I never ran out of air in 18 minutes.
This was my very first try with a plasma torch in my hands.
I have tons to learn about feed rate and nozzle height.
I cut the 3/16 at 200mm/min using a spiral profile that basically made 2 trips around each profile. I set the nozzle 2mm above the surface.
The BCNC auto level was perfect. I probed a 3x3 grid over the work area. BCNC automatically figures out the boundaries to probe from the loaded code.
There was a ton of slag left on the bottom side but the top (in the picture) was pretty clean. I just bumped it a little with a grinder.
I’m sure I’m not alone in this group but I can’t thank you enough for developing and maintaining MPCNC, LR2 and the rest. I really appreciate it.

The outside rails are 2x3x1/8 in rectangular aluminum tubing
I used 2x3x3/16 steel angle inside the rectangular tubing
The cross pieces are 1-1/2x1-1/2x/8 steel angle sitting toes down on the 2x3 angles. The cross pieces are on 10 inch centers
I’ll try to upload a Fusion 360 model of it.
Can you share what you did for the torch mount? I’m in the middle of redesigning mine to get rid of zip ties, but trying to find the best way to hold it. I like your solution as a start
@Bryan
I originally 3D printed a beautiful 2 piece adapter that gripped the torch and had the same mounting pattern as the router base plate. It worked ok but didn’t hold up to the temperature (I used PLA filament)
What is pictured are 2 1-1/2x1-1/2 angles about 3-4 inches long welded back to back with each other. I can’t remember the exact angle but it’s something like 15degrees to keep the torch vertical. I drilled holes in it to match the holes on the LR2 router plate and then added a couple of other holes for the tie-wraps to go thru.
