Rebuilt the config and it is working. Bizare.....

I dont know what I did but it was homing correctly. Now it doesnt say "MAchine not homed" when I start up and when I press cycle start it does nothing. I can jog it around no problem, can even run a program. But I cannot get it to home. I put an axis on a home switch and the cncm.hom is su...

Everything went fine. Upgraded to Centroid acorn in 6 hours. Used the terminals not DB25 and it worked great. Going back tomorrow for extensive testing and trying to find a weird issue. Sometimes I cant put it in fast jog. Only slow jog. Restart CNC12 and it works in fast jog. I will look some more ...

I'll ignore your first sarcastic statement. Your second one makes sense. Thanks. I'll check the acceptable ttl gate levels of the drive and go from there.

I don't understand it. The docs clearly shows either way works and they even give you examples how to wire them. I dont get it, but I'll bring a db25 cable just in case though. Is there some undocumented issue with connecting step/dir to the terminals? I have done over 30 retrofits. Granted most of ...

Its actually quite a simple machine. Next time I will create a thread and put everything in it. I have another machine I ...

I am not using differential mopde I am using single ended.
Acorn +5v => step+, dir+
Acorn step- = > step-
Acorn dir- => acorn dir-

I was planning on wiring step/dir to the terminals not the db25

Thanks Marty for your response. I am the one who converted it to linuxcnc. I was just reading that people was having issues with pacific Scientific drives with Acorn. And I don't see those drives in the Acorn Wizard. I am to be converting this machine this weekend so I hope to not have to scramble t...
