Building My First CNC Router, Looking for Advice & Other Info

I holed the extrusion cad model then emailed them the model as a .stp but you're using solidworks which they do so you can send them a solidworks file. Make sure the holes are the correct size lol, should be 13mm I think but check this they can tell you if you ring them.

As for counterboring just tell them to counterbore every hole on 1 side with the correct size head but again they will know this is a pretty standard operation. There's no need to model the counterboring.

Make sure your hole size is correct! I can measure the correct bolts with a vernier calliper but will have to wait till tomorrow.

You are using 9045 and 4545 extrusion? If so you will have the same issue I have if using BK12/BF12 ballscrew mounts the hole distance is 45mm between the tracks and the hole distance for the mounts is 46mm.

My Y axis I'm having custom mounts made for the gantry I'm just going to wangle the mounts into T nuts but did consider custom T nuts offset by 0.5mm. I still might have them made.
