New Build, Aluminium Frame Router/Mill

[routercnc]

Hi Dave,

Looking great so far. The other option is to slot the holes for the lower bearing idlers - might have to be slotted at a slight angle to avoid hitting the stepper.

Yes that would be an option, it would mean having bolt heads on the outside though, not a critical point though.

Will try a smaller bearing, 24mm dia instead of 26mm, should be enough.

How are the solution for the X-ballnut coming along? Kinda stuck on the same thing myself.

I have managed to use the standard ballnut mount blocks for all axes i hope, i just need to finish machining the spacer blocks for the y axis and do the fitting, hopefully be all axes connected this weekend :)

Stripped it all down today for final finish and fit, ran out of time to start the rebuild but hopefully tomorrow will get some picture update.

I was going to put the Y axis motor to the rear of the frame but it didn't play nicely and would cost me some Y traverse so I'll leave it at the front. The new idler bearings seem to have sorted the belt issues out, hopefully the motor adjustment slots will be enough to take up the slack without getting a shorter belt.

My plan is to mount the rails and screws square to the beams, its all pretty rigid and square when assembled so with a bit of luck it will all work out exactly as the drawings indicate.

Got some motion assembled today, final fitting takes a lot of time...







Next up is making the bracket for the X axis motor. Then i might remove the grease nipples on the lower X carriages as they are costing me 20mm of travel by hitting the side frames.

A little more fiddling here and there and we should be ok to start planning wiring runs etc.

I like how simple it looks, but I know how much careful planning/drawing it took to get there.
