I did just find 16T 2mm pitch pulleys on Amazon for $8/ea.

That is way to much for those, they should be from 1.2 to 1.7$/ea.

Just make sure the bore is what you need.

The ebay link is out of stock on 16T. I searched Amazon earlier and it didn't return any 16T sets like you found...much better set of 5 for same price as one I found lol. Gotta see if I have enough belt now to do the whole thing or of I need to order some with it.

1/4" bore (6.35mm). Still that 1st Amazon link you posted for a 5-pack will work fine. I found my belt in the garage...20ft, and I'll need 10ft more, so I'll order a 5 meter roll of the super cheap stuff and use it in the track as the rack. The belt I already have is Gates, I'll use that as the actual drive belt.

That's a sexy looking beast you built there Rod. Especially that Z axis, although it's all very nice indeed!

Thanks, it only took 3 months in my spare time to design and build...

The whole machine, or just the Z?

I'm basically running down a list of stuff to do so I can then progress into plasmac.

Had a hiccup with the float switch, got that all squared away and got my torch holder put together. I'm not real sure how to test touchoff, I have no idea how or where to get g code files to test the base machine.

It does do 1200in/min without crashing. I reduced that limit to 900in/min. And I don't see the need for that much, to be honest. Sure am glad it stopped softly every time

The Z axis complete and Y motor assembly. Making the gantry to mount it to only took a day or so.

There are some example gcode files deployed with plasmac. A lot of people cut the Plasmac Spanner
github.com/LinuxCNC/linuxcnc/tree/master/nc_files/plasmac

Thanks Rod. I was going strictly by the plasmac guide, which emphatically says to have a good base machine (no crashes, limits good, no plasma connections, and able to run some gcode). So do you mean I should be ok sans running some gcode, all other things being good and well?

Try it, it should work as PLasmac does all its magic without touching gcode . But there is other sample code published as part of Linuxcnc.

BUt I would recommend that you learn enough about Gcode to draw a square in the air. That may teach you a thing or two about G64 offsets before you get going...
