I think you should just upgrade to a better board wink
Just remember I stopped using that board for a reason.  Of course that reason wasn't that it didn't work, rather I wanted a better board.  Have you tried swapping that driver with one from another axis to see if it is a stepper issue?

Never even thunk of doing that. hmm

However, what do you think of this:

and then purchase the 8825 driveroff Amazon? I say that because I would never use the SD slot on the other/more expensive kits.

Run a few prints, some large and some small, and I still have it present. Sometimes on the first few layers, sometimes halfway through. The belts are not slipping and I have fans on all motors and 2 on the board, so i know it could not possibly be due to overheating.

And it is pausing during longer prints as time progresses. This is causing me to think it may be the stepper as I have read here http://www.soliforum.com/post/18295/#p18295

Thoughts?

Never had it happen firsthand, so my knowledge is limited; but with full fans on board, and after reading that link you posted, that would be my next step (no pun intended).

Just a shot...but maybe excessive belt tension?

Thank you for that!
Last night I flipped the left Y pulley, now the top and bottom belt paths line up nicely. I loosened both belts and a smidge on the X and everything flows smooth now. Printed some replacement Y brackets lsat night which turned out great.

Run a few more large test prints this weekend, but it's already running much better.

Awesome!  Glad to help!

I took a pic of the original belt tension before the upgrade and matched the current setup according to that. But shouldn't it be about equal tension as before if it worked? I understand Lawsy's Y carriages are a bit heavir than stock SD, so I assumed equal tension, if not a bit tighter, would be the way to go.

What's your theory?

At first I thought something was wrong with the print that they weren't sitting in right, but they are solid and I need to use a spare 6mm rod the pry them out.
