Thank you Marty, I should have done some kind of spread sheet myself. Will run it all to ground tomorrow and let you know how it goes.

Re: Encoder Differential Error

<SNIP> Yes, got it, one tripper and software limits, I was sort of aware that would need to be the case. X switch is in the middle pretty much, Y too. Trips are at either end of the range of travel relative to the single switch. Will contemplate second switch. John If you have one switch you need t...

Have not gotten that far. Will likely do so this week or next.

Re: Encoder Differential Error

Marty, Please scan the sheet that came with the encoders. I dug it up and I think I see my error! Gotta check tomorrow but it appears that I have the A and /A AND B and /B wire pairs inverted. I'm guessing that would be enough to screw things up. Let me know if you know. I'm sure you will see the er...

Re: Encoder Differential Error

If you have one switch on X and Y axis then you have to rely on soft limits for the other end. You can't use one tripper on each end of the axis to trip ONE switch. WHICH end of X and and WHICH end of Y is your switch on?? Your alternative is to add a physical switch to the other end of each X and ...

Re: Encoder Differential Error

Marty, Answers below: I noticed you PID screen, your index pulses are all showing (asterisk next to each axis letter) that's too coincidental. Are your encoders connected when you took that picture? So you put the connectors on both ends of the cable. Where did you get the cable? Show picture of the...

Re: Encoder Differential Error

Marty, Again thanks, read on: Also, the way you configured your home/limit switches aren't going to work as they are for X/Y. Please tell us where your switches are on your machine and why you configured the software the way you did: Limits.JPG >> I have one single NC switch on X and one on Y with t...
