The machine "works", as in they've made a half dozen ugly test cuts.
But they have not figured out how to make the THC work right and some
other finer points of perfection still need fixing. Things like
squaring the gantry are currently done by grabbing the bridge and
pulling it forward against the end stops before turning on the drives.
Many shitty machines are squared like that. If Mach is not licensed the
THC stuff is not functional at all.

Subject: Re: [Emc-users] Linuxcnc vs Mach3 for Plasma Cutter?
Mach3 is now pretty old.
Is there a legit license installed with the software?
Oftentimes machines were shipped with a demo license only. (limited
Gcode support)
CandCNC used to sell a lot of Mach3 software with their systems.
Go look at their site now.
If it works... why change it? Chances are that the torch height
control won't work with LinuxCNC.

I don’t want to start a big Mach bashing. I just want to hear some
opinions from those who have set up a simple CNC plasma machine with
both Mach and Linuxcnc.
Are there any inherent advantages/disadvantages of one over the other
for a plasma cutter?
Here where I work they just purchased a cheap plasma table kit and
they are setting it up with Mach3. (they being not me.) My self,
having zero experience with Mach3, probably would not have bothered
trying to even install Mach.
The machine is a simple stepper gantry using a Gecko 540 driver pack
and I think there is some form of THC contraption as well, but I have
no details.
The two people setting it up know next to nothing about Mach3 or CNC,
and even less about Linuxcnc (hence their choice to go with the Mach3
setup.) My guess is that they are just following the instructions
that came with the kit.
Unfortunately I am too busy at my end of the shop to offer them a
whole lot of assistance, and since I know nothing about the plasma
side of cnc...
However I have threatened to come down to their end of the shop and
install LinuxCNC on it while they are not looking😊
