General Mach Discussion / Safe Z Not Working...
« on: September 19, 2014, 05:10:23 PM »
Ok, so i am fighting an Auto Z problem, see my other post, and i noticed another problem with Mach3 today.. Is this software just this buggy or what???

So i have Safe Z turned on, and its set to retract to +3.00 when stop is pressed. So i was testing it and noticed it doesn't work anything like i thought it would.

Running some code and its moving around, click Stop, the axis's stop moving, the bit retracts to +3.00 above Zero, awesome i thought, but when i click Cycle Start to continue where it left off the bit stays at +3.00 for the rest of the program cycle. Why doesn't it automatically go back down to Zero and then to the working depth and continue???

General Mach Discussion / Auto Zero Z Crashing Bits...
« on: September 19, 2014, 05:05:47 PM »
Trying to figure out what the heck is happening here, its been working fine for a day or so then today i changed bits and grabbed the probe and put it on the work surface and clicked auto tool zero, it came down slow like it always did, touched off on the probe, but then instead of retracting up it tried to ram the bit into the probe, snapped the bit and gouged the probe doing this.

So i put a piece of wire in the chuck so i had a disposable part to test it again instead of an expensive bit and again the same routine, touch then drive it down into the probe. It used to touch, then retract up a bit above the surface.

I checked the button script, it hasn't changed, the probe thickness is set correctly, i'm just plain stumped!!

If i manually set the bit to just touch off the material surface and zero it manually everything is fine with the machine, but the auto tool zero doesnt work and i cant figure out why because it used to.

What am i missing here??
