If you just want a quick fix for now until you decide to cancel it, just put a "G55" in your startup routine in general settings. Delete it when you want to stop doing this.

I see the problem now. twenty feet of pipe. Ok, spirit level it is, clamp the thing on one end and leave it there until you're done.

For the pipe problem, clamp something on the far end of the pipe like a U-bolt or a big exhaust clamp and either reference it against the bed of the machine or put an inclinometer on top. The first method gives better accuracy but is a bit more fiddly ;)

Could be but if so I'm in unknown territory. With that said it should honour modal commands from Mach along with all the other commands.

Stainless on a small mill - If it cuts and nothing breaks that's about as good as it gets. Change nothing :D

Check your initialisation string just over the constant velocity/exact stop checkbox. If there's a G61 in there swap out for a G64. If this doesn't fix it I'm stumped :(

Sounds like it. Change this in Config>General config or just insert a G64 command in the start of your program.

^ Put each pair of wires in a shielded cable, so if you have a switch or a DC motor, use 2 core shielded. A block of 2 switches can use 4 core shiielded. A 3 phase motor uses 3 core shielded and so on. The idea is for the current on one conductor to cancel out the magnetic field produced by the other while the shield reduces the effect of external influences. Equally, external RF and noise will affect both conductors equally and oppositely, reducing its harmful effects.  Just twisting pairs together goes a long way towards this, shielding increases your margins even further.
This goes both ways - shielded/twisted wires will radiate less trash signal than loose single cores.  ;)

Well, one possibility in the absence of a home switch is to bolt a block on one corner of the table and square it up with the cutter, then to get your "home" positions in X and Y just touch off it with a wiggler and set the zeroes by hand.
It's a nice little mill though, you should be able to make some tidy work with that.
