Aluminium Profile Type Router - Initial questions

Gantry Sides done - need to counterbore the M12 bolts slightly but waiting on a 13mm drillbit for clearance hole..


Ended up ordering a new 60V output transformer. Fingers crossed I'll also have the closed-loop steppers and drives turning up in next few days. :)

I'm thinking about cable management, its probably been a bit of an afterthought so far, but I'm thinking having it in my hands will be easier to "visualise". From other post's I'm thinking something like https://www.ebay.co.uk/itm/R38-18mm-...K/163618534489 or will that be underkill?
I'd have 2 x 8mm coolant pipes (and 1 air TBC), 1.5mm CY for spindle, Z and Y motors, encoder cable? Y and Z limits.

Also trying to find the right pulleys for Y and Z - planning on 15mm HTD5 (10mm bore) in 1:1 ratio - but how many teeth do people go for?

20T are what I find best, don't go less than 18 because it makes it difficult with the boss size and you don't have much left for the grub screws. Also, don't try boring them by just drilling on a drill press, they need to be drilled and reamed accurately. I suggest if you haven't got a lathe or a very very good drill press or Minimill then buy them already bored.
