Thanks Tweakie, I should have asked first. Do you think all the TB6600 are the same? there sure is a wide variety of prices. My original Break out Board is fine, it's just the one axis on the 4 axis board that doesn't work.

Your guess is as good as mine - I have purchased some electronic stuff from China which is absolutely excellent and other stuff which turned out to be junk.

Tweakie.

I don't like to buy stuff from China, but it's twice as much here in the US and it's still made in China. ??

I'll probably just unplug the Y axis and plug in the A axis and set up another program for a lathe. Seems better than tearing apart my whole electrical cabinet. Winter is trying to move in so it will have to wait.

Well, I went back again and basically started over. I began testing any connections I could and check voltage. I had been testing the input from the 26 pin cable and at the break-out board. I was only checking the signal at the spot where the green wires are, then I finally tested it at the red and white jumper wires. There is a bad connection somewhere between the break-out and driver board. I put a jumper over the 26 pin connection and it's working great.   I have a better picture but Crappy photo bucket won't let me upload until I read 50 ads, or pay $15 a year to stop them.

 

Here's the better picture. I hope to try Scorch works wrap program. If I can figure out where to start.

Is there a reason why a couple of my stepper motors get quite warm even when they are not running? I was running a 3 axis project and not using the 4th axis and the motor got very warm just sitting there. I noticed one of the other motors was warm after I had the machine on for a while even though I wasn't running anything.

That is normal for a stepper motor. They draw power even when sitting still.

OK, thanks, I noticed it before but they aren't so hot I couldn't keep my hand on it. Just not what I expected.
