Ok well I tried it that way too. No movement either. Is this to rule out noise on the step signal?
Just trying to look at this with fresh eyes this morning. I am using the US digital E2 series optical encoders. from talking to people I know they can be buggy and subject to noise issues. One of the first things I though was at issue is that the O ring in my Z axis encoder cover had disintegrated and left pieces of itself all over the encoder. I cleaned it off real good and put it back on which lessened the issue. So I thought maybe the encoder was still mucked up so I swapped it for my Y axis encoder which was in good working order to rule out a bad encoder. Still same problem as before plus it really doesnt explain why the error is moving only in one direction.
My question is this. I have since lost the spacer tool that you use to position the slotted disk the appropriate distance on the shaft. I still have pretty good eyes so I just eye balled it exactly in the slot of the reader head by sight. Do these things have really fickle focal lengths or something? could that be the issue if it is not absolutely perfectly aligned?
I have two new encoders coming in the mail (with alignment tool) to help rule out damaged encoders (take them off and put em back on a few times and things can get less than perfect) as the old encoder from the Z, now on the Y is still kind of buggy. Also after talking to ta couple of people I also purchased US digital's PC4 cable drivers to snap on the encoders. They are not specifically designed for noise or anything but the have a resistor on them that helps quiet down noise on the encoder (or so I have been told) anyway. Thats where I am today. machine still down and I have work to do and can not do a thing about it
Still looking for things to try
