) mach 3, and everything works great and is up to date. I have a 20 cfm compressor, dry clean air, well over 100 psi at the unit while cutting. Clean brand new consumables...., ect....
While cutting, the damn torch will be cutting along great, at the right voltage/height and then, it goes out, there are no errors on mach 3 or the pm65 and a second later re-fires and keeps cutting like nothing happened. While the torch is off the torch still moves like it's cutting.
I'm so lost, there is nothing in the G-code that tells the torch to turn off, and the same gcode file re-ran will produce cuts with the torch cutting out at different spots (random) so there is nothing specific in the code. with the DTHC turned off, it still does it.
ANY help would be greatly appreciated.
This has happened to me with finecuts @ 40 amp on 16 gauge, 45 amp tips @ 45 amps on 1/4" and 1/8" and 65 amp tips on 1/2" and 5/8". Soooo on everything I've cut.
I honestly think in the next week my handtorch will see more use then the whole CNC table because I'm goign to cut it into bits.
