General Mach Discussion / Re: Home Switch Sensitivity Problem
« on: April 01, 2008, 09:24:19 PM »
Just an FYI.

I could not get the debounce setting to work with the prox switches I was using. The switches had a 4mm range and I couldn't set the debounce high enough to get it to back off far enough without it hitting the switches because they were inline with the metal that makes them. Rather than re-align the switches with new mounts, I opted for mechanical plunger switches. All is good with them.

The debounce setting is a nice idea but it causes a lag in the axis recognition of the switch as well as the stop of it's reverse away from the switch. That's not good if the switch is in a position that interferes with that particular axis of travel. It tends to release the magic smoke from said switches.

General Mach Discussion / Home Switch Sensitivity Problem
« on: March 31, 2008, 11:46:34 AM »
I'm setting up Mach 3 on a new CNC and I'm having problems with the Zero set-up. The prox switches are so sensitive that when I tell the software to reference an axis, it makes the switch but doesn't fully back off of it and the switch will flutter.

I don't see a setting for telling it to back off the switch to a soft limit in the config menu.

What I'd like the machine to do is reference the switch, then move in the + direction one inch, then zero the DRO and call that position home and Zero.

Am I missing something simple?

General Mach Discussion / Upgrading From Mach2 to Mach3
« on: December 23, 2006, 10:00:28 AM »
Hey all, I have a CNC in one of my production departments that is used for daily production of foam parts for a major customer. It works nicely and uses the Mach2 UI.

I would like to upgrade the UI to Mach3, but I'm afraid of breaking the machine and knocking it out of production. That would be an expensive mistake. Is there a step by step guide for upgrading from 2 to 3 that covers all the pitfalls including what settings I'll need to transfer over to Mach3 and where to enter them?

My manager really wants me to upgrade to a newer UI, but I do believe he'd have my head bronzed if I took this machine down for more than a weekend. Help?

Thanks in advance.
