FAQs / Tripping Limit Switches

« on: June 04, 2020, 09:11:03 PM »

Hi,
I have an Industrial CNC 4x8 machine with spindle. Using BobCAD/CAM software with Mach3. I am having issues with tripping limit switches. The tripping is not consistent but sometimes occurs frequently. Resetting does not always solve the problem. I have been backtracking a line or two or G-code and using the "run from here" and it may take more than one attempt but it will go through. I also get "missing words" error messages. Here again I would backtrack a line or two of G-code and use the "run from here option" and eventually it would go through. For both of these error message sometimes after I reset and try the "run from here" option the machine will go rogue and go off in a undetermined direction including backwards.
I don't know what I should be doing to resolve these issues. Thanks

First, I am new to this CNC operation so I may be asking simple questions but it hasn't been obvious to me.
1) tool changes: I first thought that when I entered tool info in the Bobcad/can software it would transfer to the Mach3 software, wrong. But I have tried entering the tool info height by actual dimensions, no dimensions, and difference in dimensions from the first tool. No success. What do I need to do?
2) the Mach3 software stops spontaneously during the project. I need to reset and cycle start each time. Why?

Thanks, Kevin
