General Mach Discussion / Debounce

« on: September 05, 2016, 05:34:15 PM »

Hi
I have a question about the debounce setting, A few months back I was having a problem with a program running were it would suddenly stop and I would have to reset  and start running again. It was  recommended that I increase my debounce setting because I probably had some ground issues or perhaps something was unsheilded in my wiring. In reading posts since then I have read that some people have these issues and have theirs set at a variety of numbers. My question is how do these affect how Mach 3 runs when you are not at the ideal 0 setting.
Thanks bill

Hi
Just so I understand, The one lead from the capacitor will share the input place on the board with the input wire say for a limit switch. The other wire from the capacitor will go to were I have the shielding grounded. Is this correct, sorry I have no experience with this.
Thanks again for your interest.

Hi Tweakie
I was looking at the capacitors online. I don't know much about these, how would something like that be added on. is there a terminal bar for something like that

Hi Tweakie
Posted earlier but don't see it up, wanted to say thanks again the debounce worked at 500. I ran the roadrunner a few time with the spindle running with no issues.
This afternoon I put a pieces of Styrofoam on the table and ran the program with out it touching the foam went fine. Then I ran it with the end mill cutting in about a 1/4"deep, both times I ran it it tripped a limit about 3/4 thru the program looked about the same place, I reset both times and it finished with no problems. any idea whats going on.
Bill
I had said I posted earlier and it's not showing, what I had asked is should I play around with that 500 setting on the debounce setting perhaps to see what the lowest setting it could be

Hi
I wanted to add to what I wrote might give some clues. was reading on the web that the VFD should be on its own circuit, switched that and spindle can run now a few seconds before tripping the limit, also set the debounce to 5 that makes it last a few seconds longer. but still is tripping

General Mach Discussion / VFD problem

« on: June 25, 2016, 09:34:43 PM »

Hi
I have been running the roadrunner gcode to get use to my machine coordinates, thought I would run with my spindle on also no tool. When I power up the spindle I get a limit switch tripped, when I reset I get a Emergency e stop requested, I can run the program with the VFD in power but if I start the spindle I get the emergency stop. I have the power cable to the spindle shielded and grounded at the VFD. I read recently that it should be grounded both sides is this my problem or could it be something else
Thanks Bill
