Show"N"Tell ( What you have made with your CNC machine.) / Ship Wheel
« on: April 06, 2018, 11:45:41 AM »
Hi All
This is a ship wheel I made for my daughters school. she is in the Peter Pan play, I designed in Artcam and machined it out of the 2" blue Styrofoam that Lowes sells. Did a painted finish.

General Mach Discussion / Re: Debounce
« on: January 18, 2018, 04:16:57 PM »
Hi Rich
Thanks for the reply, I don't have my spindle controlled by Mach 3. I was wondering if the debounce is set high or at any level if that affects missing steps or compromises mach in any other way.

General Mach Discussion / Debounce
« on: January 18, 2018, 11:42:24 AM »
I done a bit of searching and haven't found this part of my question. I think I understand that the debounce setting can help with electrical noise and errant limit switch tripping. And it is best to find the problem a correct it. My question is what do high or low  debounce settings do to Mach 3 performance what are trade offs
Thanks Bill

General Mach Discussion / Re: VFD Noise

Hi
Thanks for your interest, I don't know a lot about interference, You mentioned conducted interference could this be a possible cause in my case the 3 phase power for my shop comes into the building as a separate line that is used for my spindle and the VFD. the power for my PC and control hardware in single phase and again comes into my building as a separate line they are both isolated and not shared . As I get into trying to find my noise issues would this be something I would add to my list of possible causes.

Hi
My VFD and spindle are three phase all separability fused and lines in the building. My PC and control box are single phase and separate also.

Hi
My VFD is plunged into a separate circuit from my control box, if I am understanding you correctly. From what I have read on the forum over the years is that the spindle wires and power to the VFD should not be in proximity to the limit switch wiring. while I am using shielded cable on everything I thought I would try moving The VFD and the spindle wire to see if that might be my problem.
Thanks for your interest

General Mach Discussion / VFD Noise
« on: November 17, 2017, 11:07:53 AM »
Hi
Been getting a tripped emergency switch every half hour or so while running my machine. I know I have some noise interference so decided to try and isolate it. I ran my machine for a couple of hours just cutting air without the VFD and spindle running no tripping so I am confident there lies my problem. My question at one point while running the g code maybe 45 minutes into the program everything stopped no emergency trip just stopped could not move anything even by rewinding g code ended up shutting down the computer and restarting ran the same gcode for a couple hours with no problem was checking other noise sources florescent lights, my water pump for the spindle, dust collection. just  the VDF trips it will work on that. any idea why it would just stop.

I read this forum everyday for a couple years, and have learned a great deal from all you guys
Thanks for sharing

General Mach Discussion / Run from here
« on: February 08, 2017, 02:41:24 PM »
Hi
I was reading a post in which run from here was being talked about. I have a slight noise problem in my wiring which I have been trying to find the culprit, In the mean time when running code sometimes during the end of a long run I get an estop and must run from here. Mach rewinds the code and must go thru to the line requested which can take quite a bit of time if it is a long session. Am I doing this correctly or is there a faster way to run from here.
Thanks Bill

Hi
I had something like that a while back, the coupling from the motor  was slipping as it was not tight would make a thud sound
