Cletus' Crossfire Build n Mods

[TomWS]

@Cletus

Hey Tom, how did you mount your THC?

I put it in a Nema 4 enclosure, covered it here: Finally completed my CrossFire mods - #11 by TomWS

Did you cut the OEM case and flush mount the display?

I took the THC03-02 enclosure apart (easy to do), took the guts out and mounted in the enclosure as shown in the post I referenced above. The front panel display and switches are nicely mounted on an aluminum extrusion so I kept that, but cut off the excess top and bottom with my bandsaw and then mounted it on the front panel of the Nema4 enclosure with a small rectangular cutout (for the display electronics) and fastened it to the enclosure with a custom strip of 3M VHB. Nice and tight and splashproof.

Is the divider board mounted at the Plasma cutter or is that also in the control cabinet.

This is shown in the post.

Do I really need the proximity sensors or does the floating z axis / microswitch do a decent job?

I think the floating Z axis is fine unless you’re doing material thinner than 16Ga. This will warp and flex from the weight of the torch. I’m in the process of finalizing a “Poor man’s ‘Ohmic’ sensor” that SHOULD take care of this. We’ll see. PCB is due to arrive tomorrow. Maybe have it working by next Monday…
