G38.2 randomly stops

ArcEye,

Thanks for all your help. I think I am going to follow the plan I have and see how it affects things. Look anything has to be better than what I originally done. Motor wire, control wires, PSU wires all bundled together had to be asking for trouble. This can only make it better. Aside from the cost of the crimper for the ferrules, it isn't costing me much to do. This is a hobby machine for hobby use so as long as the wiring is sound and trying to follow some best practice, I feel like I will be OK. I owe you and Andy a great thanks for all the help. If either of you are ever in middle Tennessee, I will be happy to buy you dinner and a few cold ones.

I am hoping that with the rewiring of the cabinet, that I can go back to my original setup and pull the input pin low, and rerun my test to see that noise isn't interfering with it. Although, I am going to take your advice and use 24V relays for my probe and limit switch circuits. (Because I already have the relays)

I spent a lot of time in the documentation off and on the last couple of years and some of it was tough for me. I can't program at a level to contribute that way to the project, but making suggestions and or corrections to the existing docs I can do. Making some tutorials that some new people can use that actually works them through what has to be done to set things up is something that I think that I can give back to the community that has given so much to me. I just don't want to give misinformation if I can help it.

Regards,

Joe

I ran them separately in my control box:

I have no idea if it helped or not, but it wasn't difficult.
You will note that that was done before I discovered bootlace ferrules

In retrospect the terminal blocks for signal wires were not useful, but the bussed-together ones were useful for power supplies. If I was doing it again the motor wires would have run direct from front panel connectors to the drives.

Andy,

That is still a pretty neat wiring job!

I plan to run from the controllers to the MIC connectors in my panel too. Also, the piece of metal that all my MIC jacks are run in, I think I will use either a piece of fiberglass or plastic to insulate the jacks from the metal drawer since my AC ground will be attached via the PSU cases. I am thinking I will take an aluminum plate isolated from the drawer with standoffs and mount my controllers to them. If I turn them 180 degrees, I can run the motor wires on the outside and the signal wires to the inside of the drawer.

Thanks for pointing out the ferrules. They will make a neat job of it and reduce the risk of a stray wire strand from being naughty.

As a side note, My motor wires from the MIC jacks to the motors are 2 sets of 22 AWG twisted pairs. They are open to the air. Should I replace these with shielded wire? I mean, I will have signal wires routed along side them eventually in the cable management, or do you think the twists will keep it under control?
