Hi folks!

Little bit about me: I’m a hobby woodworker and guitar builder (acoustic and electric), albeit one who has been on a building sabbatical of sorts due to intensive work schedules and new parenthood.

Waaay back around 2013 I decided a CNC would be a fun and useful (but certainly challenging!) addition to the workshop, and allow some designs that would be far more difficult to do by hand. A few hours at night spent finessing designs is also something that can be done quietly enough not to disturb the rest of the house! I have zero real world experience with this sort of thing, just years of lurking and reading.

I purchased a CNC kit from George at XZero in Canada, who shipped most of the machine (Thankfully charging for those parts I received at the time) before falling off the radar due to health issues (from what I’ve been able to gather). Basically I have all the extrusions and machined aluminum parts and 2 of the three ball screws needed (and a massive bag of t nuts and bolts). Thinks have calmed down, so I’m looking to build up the rest of the system. What I do have seems very sturdy.

The router is a 1200mm x 790mm x 300mm (measuring the rail lengths) design, double checking dimensions on the rails and carriages it was dimensioned for (looking like HiWin 20mm rail with long and short blocks is the right fit, but need to dry assemble to check spacing).

Right now I’m looking for advice on a few things. For starters, the X axis ballscrew - I believe (but can’t confirm) that the router was designed with a 2010 ballscrew in mind. The Y and Z axes are 16mm (need to check whether 1605 or 1610). The plan is to mount a Teknomotor ER25 spindle, original plan was a 2KW model. I want to machine wood mostly, but have the option for occasional aluminium/brass machining. May require adding stiffeners to the top of the Y axis gantry, but I figure that’s for a next step. Some similar machines have 2510 or even 2525 ballscrews, but that seems like overkill. Or is it just enough kill?

The options for driver systems have also grown considerably. I’m considering an EdingCNC board (local, good support, good local forums, Ethernet and USB interfaces) and JMC 180 watt closed loop integrated servos. This seems like a good option on paper, albeit one requiring a pretty hefty power supply.

Im also looking for a good source on the linear motion bits I still need - HiWin Rails and carriages, and the X ballscrew. There are some interesting options on Ali (like BST automation) - that is until you add shipping and duties, at which point I figure I’ll just buy local for the added peace of mind. But if anyone has good tips, I’m all ears.

These seem to be the big things to work out - wiring and cable management should be feasible, and I’m open to suggestions regarding a good dust boot to fit a modestly powered 100mm cyclone collector.
