Toby,

I check it out and your right, all Rick has to do is follow your instructions.

I shoot you a PM for phpBB to play with.
If you interested.

What I am interested in is if it ever stops short when you are not using the Home Y button, just when it is commanded to do a long y axis travel move. Hi jsc I tried the attached GCode. The interesting thing is that I was able to run the code once with no problem but the second attempt wasn't succe...

@jsc

I tried that when I made the video. The result is that it stop's and thinks it is on zero and goes to 250 again and that shoots over. I stop then with Emergency Stop to save the stepper.
If I put you code in it goes back to zero. I tried roughly 30 times.

Yes that is exactly what's going on.

Thank you Toby I really appreciate taking the time to help.

Just troubleshooting suggestions to try to narrow down what is happening. These questions aren't specific to anything I have in mind, just trying to get more clues. As it is the behavior is so odd given there's no mechanical explanation for the z-stop being triggered. I can't tell from your video, ...
