Hi all!
I´m at present doing 4 axis machining of polystyrene foam, using DESKPROTO to generate g-codes, and an A axis to spin the part.
I´ve just noticed something strange and problematic in MACH3 when I need to pause in the middle of a routine.
I touch the FEED HOLD button on the MACH screen, and within a few seconds (probably MACH needs time to reference where it is to ready itself for starting again)…MACH pauses, as if on Hold. Fine up to here.
But when I wish to re-commence, and I click on the Cycle Start button on the MACH screen, the A axis mysteriously and abruptly spins to Machine Zero, no matter what angle the routine has been working at, and milling commences.
Attached a Screen Shot: you can see the a axis is now at 1.9125º, bt it should be at 0º. (which it this case is actually 0º at Machine Coordinates)
And if it had been working at say 270º, as happened some days ago, it still spins abruptly to Machine Zero for that (A) axis.
Am I doing something wrong here??
Thanks!!
If its not obvious, I´m pretty much of a new-comer
