I have had a play around with the bearing blocks, all of them had both bearings facing the same way round rather than back to back, also there was a larger amount of slop in at least 4 of them so I have ordered some alternative bearings to replace with as I was getting 0.4mm of end float once everything was tightened up.

So whilst I am waiting for bits to arrive I am trying to source some bits I was wondeing if people could let me know if they have any suggestions for the following?

e Chain? - have found a reasonable supplier on eBay for it so might just go down this route about £10-15 for a metre

Breakout board combination: Can someone tell me if I go down the PMDX or smooth stepper route what I would need. I did not order a BOB when I bought my stepper drivers as I had heard so many people knocking the cheap BOBs. So my question really is which of the two do I go for SS/PMDX and if so what do I need as well as this to connect to mach 3 (I am not talking limit switches etc I just mean between stepper driver and PC)

Finally now I have the rails levelled using shims I have a litre of WS resin and 209 hardener I dont use I would be willing to let go for a good price if people are interested please IM me :)
