made a bed/y carriage for the cnc tonight

and now, bed time

no idea how I managed to mount one of the X rails 5.3mm too far back, but here we are

(it's probably my amazing welding abilities)
so that's *most* of the holes in this part done. still need to attach the Z ballscrew and servo bracket to it

the spindle mounts on a plate that will also have the rails for these bearing blocks, so they don't need to extend down any further than the current z position

(there are two more bearing blocks that go down there but I haven't put them on yet because they cover the screw holes for the other bearing blocks. dependency chains!)

30 to 40 holes in a steel plate: an easy weeknight project

you will certainly not regret drilling 30 to 40 holes in a steel plate

@emily this does seem to be a perk of living relatively isolated 😅

(I’m in a 70s apartment block; if I tried to drill holes of an evening I’d be waking up the kids who live in the unit right above my garage)

@buzzyrobin your neighbors will certainly not resent you drilling 30 to 40 holes in a steel plate
@emily shims, all precision on shims!
@RueNahcMohr yeah I'm probably just going to make a 5.3mm thick block with holes in the right places and stick it in there

I expected to need to shim things but not quite *that* much
@emily may I suggest your constrained in the same axis twice aka one rail could be rolled 90 degrees to make them non-conflicting?
I also had fun keeping the drive screw parallel to the 'control rail' on my machines, I ended up leaving the lead screw 'floating end' and making sure I had a good thrust bearing on the motor side.
On the printers, I dont have to worry about the rails being parallel, just 'level' The bed follows the control rail.
@RueNahcMohr I don't think that actually does anything for the style of linear rails I'm using? Your rails are round so a thing can rotate around them, but HGR rails constrain all rotation even if you only use one.

@emily shim time!

I think at this scale you can also call it a spacer...
