Hi all,
Before I start, this may all sound like a pretty vague question - but hopefully someone's seen this before....
I'm converting my Sieg X1 (well, actually I got it from Axminster in the UK and I've been told it's the same as the Sieg, just badged and painted differently) for CNC. I have made some mounts for the stepper motors, and hooked them up with EMC2 software via some stepper drivers.
The Y-axis is fine - the test utility with EMC2 allows me to manually run the steppers backwards and forwards, and the Y-Axis travels fine. The X-axis is another matter, though. Without the brackets on, the leadscrew moves fine. As soon as I tighten the bracket up, the leadscrew is unable to turn. I've checked the bracket, and there's nowhere it directly touches the screw - all it does is tighten the bearing block against the table (just like it was when it was manual with just the hand crank on the end). I'm pretty sure the tightening doesn't shift the bearing block at all to bind on the leadscrew shaft.
Has anyone seen this before? Without the table on, the lead screw has a lot of lateral movement in the nut block, I don't know if this has anything to do with it.
Like others on here, this is my first foray into milling/CNC so any (even basic) suggestions gratefully welcomed.
Cheers,
KEv.
