Ok.... I bought a set of 25mm supported rails and bearings from Chai on Ebay to replace my 25mm unsupported rails (fantastic service and Fast shipping). Problem I have is : I mounted the rails on my aluminium profile either side of the 16mm ballscrew (make unknown but looks like Hiwin in google pictures). The top of the "T" plate (I call it) that is fastened to the ballnut ends up 3mm higher than the top of the rail bearing blocks. Is this a common problem ? or can I buy a lower T plate for the ballscrew ?. I would mill it down, but obviously I cannot, and I do not have a big enough belt sander. I really would hate to put packers under the rails.
and before you ask....yes all the balls fell out. ah well I'm confident I will get them in (without looking first)
