Mach3 and G-Rex / Re: Help getting MACH3 working

« on: October 06, 2011, 07:47:14 PM »

I just got home to my PC and it is as I remembered C:\Mach3\ then look under what the profile name is and over to the right it will say what kind of file it is, in this case an XML document. If you click on this, it will open the XML file showing all of your settings within Mach (it might not make any sense to you at first). You could copy this file and send it or a screenshot but I would think they might prefer the file.

Have you optimized your pc for Mach? Setting the EPP and turning off all sleep or hibernation modes etc?

CncDaddy, where are you? Is your machine wired up and ready to go? Are the steppers locked up upon powering up your controller. I am away from my pc but IIRC look under computer/c drive/ Mach3/ (what ever profile you have created) or are you using the master? There is a bit to learn here. Don't worry it will take some time to learn where the answers are.

Galil / Wiring Limits

Btw, using only 1 pin for all of the switches will only allow for axis to be homed one at a time. Not really a problem for the hobbyist as it only takes a few more seconds but if production was your intent, seconds count.

Galil / Wiring Limits

Ok, there are a few things here. I am on my phone so I will summarize. First a single limit switch can be used on each axis just fine. You may use 1 or 3 pins. During your set up of home and limits in Mach you will tell the machine. In which direction the switch will be. During homing it will go that direction and upon the switch closing it will back of til the switch opens. If you have the limit set as a home switch also it will go to a home position (a coordinate you determined ahead of time, a good place to change your stock or tool). Since you only have 1 limit per axis you will set up soft limits. These are a physical distance from the switch to the end of travel the opposite direction (not quite the full travel but close). The machine will not pass the soft limit. It will also prevent you from starting a file if it sees it will cross the boundary. There is more to it than just this simple answer but this is the idea.

Also be warned, if you use the same computer to run another machine with Mach 3 or even a different profile, the homing routine will change on all profiles. There might be a way to only call up that homing routine from a specific profile but it was more involved than I was patient.

Great to hear. Hopefully it will work well. What happens at 0?

First let's call the shield and it's bare cable a "drain". This needs to be connected to a star ground (this is also where the ground of your AC supply should terminate. This will be connected in the controller cabinet only, not on the machine side. Connecting the shield on both sides will cause ground loops. This connection is only to drain the stray signals. This is how I have come to understand it. A separate wall wart to provide the necessary voltage seems to be better than sharing a supply.

Does your Reset start flashing for no apparent reason? Have you run your limit switches successfully (not as home switches) with a low (under 250?) or "0" debounce setting? If you are having to set your debounce that high there must be a lot of noise, I would sure think it was triggering a fault in Mach.
