like the idea with the funnel. there are no issues with the planner and look ahead. g64 options help tremendously with path blending I am just a hobby user On Sat, 8 Jan 2022, 15:47 Milosz K., wrote: > I cut near flammables and my solution is cutting over a water bed with a > slicone funnel

I cut near flammables and my solution is cutting over a water bed with a slicone funnel on the torch. This is a photo for illustration. https://images.app.goo.gl/cUFKnX5iMdVrHPTH6 On Fri, Jan 7, 2022, 4:45 PM Nicklas SB Karlsson wrote: > Anyone used Linuxcnc with plasma torch here. > > >

It was some years ago when I tried it, it was fine on thicker sheet, but not thin sheet, like I said, I expect there have been improvements in the trajectory planner since then. The basic problem with plasma is it needs to be kept burning and metal passing at a constant speed. You can't just

linuxcnc works just fine with plasma take a look at PlasmaC. lots of users including many for commercial purposes. On Sat, 8 Jan 2022, 12:36 Robin Szemeti via Emc-users, < emc-users@lists.sourceforge.net> wrote: > I built a few plasmas with EMC, the trajectory planner was a problem at the >

I built a few plasmas with EMC, the trajectory planner was a problem at the time with it not being able to smoothly keep going between IJ arcs. This can cause problems in thin sheet ... maybe it is better now. I always had trouble keeping the HF from the arc start out of the electronics. On Sat,

you could put sides on it that will catch any sparks, or an enclosure around it, same as I have for a 3d printer so it has its own heated environment. you could also add a water table that will catch all downward metal swarf. On Fri, 7 Jan 2022, 21:51 Thaddeus Waldner, wrote: > Use a submerged
