For the kilmn
Resistance on the nichrome wire on the “Kilmn” is around 17.5 ohms
230 / 17.5 = 13.1A if wired direct to the mains
Thermostat appears to output to an SSR although we don’t have one of those at the moment on this
So there’s an SSR missing, and it may need some power resistors to increase the resistance of the wire. I’m not exactly sure how these are setup normally
There’s also the cost of the electricity to consider.
Another option might be to just drill some holes in the sides then push some blowlamps through
For the CNC
Looks like the controller board is a bit of a pain
it’s only supported by mach3 under windows
or https://drufelcnc.com/ which is free (Windows again) but only for 5000 lines of g-code
although it would be easy to replace with something else (little red board with screw terminals at the back)
Currently googling options for linuxcnc on a rpi
Remora (linuxcnc driver) on a pi4 with a Bigtreetech board looks like a cheap option
