It also appears like your Mag-Lok plate is getting pulled sideways from the lead coming off the bracket. This may just be optical in your picture but may contribute to your angled cuts.

Checked the wiring and switch. Light on screen for Zhome never came on when wiggling wires. I ran a program and watched the light on the control board to and it never goes out, even though the Z is finding its zero on its own

The torch is angled because I was messing with the Z axis, but it was straight when I was cutting the parts earlier.

Code looks good! When the Z touches the Z home should come on in Mach 3 diagnostics. If the little microswitch got stuck it would raise to your "rapid clearance plane" height set in sheetcam. Then it should do the G28.1 code to Z0.12 and if the switch is stuck, fire from there. It may also try to reference right away if the switch is sticking. Generally these issues are something stupid simple but without being there we will have to go through some steps. Now the switch is ACTIVE LOW disabled so it trips when it looses contact. This means the switch is always on until the travel comes off the switch and it looses contact. This is how it references Z Home and the light will most likely always be on in the control box. Are you using any other inputs on the I/O board? Are you doing anything different than we suggest on that board?

Yes the switch is Active low. When torch touches the table and lifts, the switch is opened, the Zhome light comes on in Mach. The light is also on in the control box.

I hooked a multi-meter up to the switch and am checking continuity on the switch while running a program, and the switch never opens which means it never activates since its Active low.

Tell me if I am doing this wrong.

-Load G code.
-Zero X,Y
-Ref Z off of a material (this value is never consistent) Sometimes it gives me a the value I entered in the post per the DTHC instructions, sometimes its 0, sometimes its a random number. If the number is random, I do it until the number is 0 or the entered value. When I do this I ensure the limit switch is being hit and the Zhome light comes on. I have tried zeroing the Z before and after RefZ, and get same results
-Run program...watch it fuck up. Now I cant even get it to do the first pierce of part with out being to high.

The only other input we are using is X home for the breakaway like you suggest.

We are not doing anything different....we are just trying to learn to walk with this thing!

Matt.....I will be gone all week, but Chris will be calling you this morning.

[jeepsr4ever]

I am on the phone with Chris

[jeepsr4ever]

Boy all this trouble seemed to stem from a unregistered version of Sheetcam. We found the key was not present.

[jeepsr4ever]

Also you were using the wrong MP1000 post. It should have been MP1000-THC not MP1000-THCRefZ.

[tlspeed1]

Owned by a license issue....damn! I never read anywhere about the Sheetcam license.

I switched the to the MP1000-THC RefZ last night at about 8:30 as a last ditch effort, and never changed it back...my bad! I was using MP1000-THC throughout the whole process
