Router stopped less than midways
« on: March 12, 2017, 08:59:30 AM »
I was cutting with my cnc router and Mach3 for about one houre than it stopped besause a limit witch triggered, non of the switches was triggerd. I belive the program is app 3000 lines and I had just over 1000 lines done.
This limit switch triggerd for no reason I know about, it has happend ones before. When I reset it seems to be ok.
I it possible to restart the process at line 1000? I shut the PC and control off but I know exactly where 0 are on all the three axis. Or can I just delete 900 lines, of cause leave the start up lines and start from there?
Hope someone can give me some advises :)

sounds like electrical noise triggered the limit. It will recur at random times until you eliminate the noise source and/or protect
sensitive signal circuits.

You can start a program from part way through but be warned that you will gouge and otherwise wreck a few pieces of work
before you learn all the quirks. Suggest you try a few run-from-here instructions in scrap material first. Read the instructions in
the manual Mach3Mill_1.84.pdf section on page 6-7.

Thanks a lot. Will try and isolate or eliminate the noise source.

Will try some run from here in the air first.

All my motor cable was screened but the screen was not earthed. I have now terminated them to earth and run the router for some hours without tripping. I have also used run from here several times with perfect result.
Thanks a lot Craig
