Newbie Sieg X3 and or Warco WM18 CNC conversions

[Doddy]

1. AXBB is fine. I use a UC300ETH on my SX2.7, but only one port (a second port controls, separately, a Starmill).
2. Go Digital drive!, I've used 2DM860Hs but there's plenty out there. I'm sure someone will express a preference.
3. I've used a 3.1nm '23 with a 2:1 belt on Z (same on X/Y). I've never encountered a problem with this configuration - noting the X3 is a bit bigger.
4. Consider your driver options - if you can run AC then it's just a case of bolting a transformer into the control box, it's quite a sensible choice for KISS,.
5. Not the X3, but the long-bed SX2.7. I just replaced each trapezoidal with a same-length 1605 cheap Chinese ballscrew, appropriating the same mounting holes for each axis (though offsetting and mirroring the motors with 2:1 belts into the space-frame of the machine). YMMV.
6. Nope, but I gave up trying to find 3rd party designs (mainly because I don't talk Sketch-up and neither did F360 - in the end I realised I was wasting more time chasing these than actually just eyeballing the machine and designing the plates, mounts etc myself.

Just my experience on a SX2.7L - not the X3, you'll have to take the above with a pinch of salt.
