CNC Router V1.0 (For Cutting Multiple Materials)

[biketrialsdave]

Hmm I may have to re-consider the steel then. The cost of getting all this aluminium machined is going to be a bit eye watering!

On a side note, what would you recommend as the minimum internal fillet radius? Or should I leave internal corners as right angles and assume it will be filleted to whatever when machined?

Not much progress with the machine at the moment... I've gone off on a tangent with designing an Ethernet motion controller for Mach 3 (don't ask how that happened!)

On a side note, I also have a job request up for yet another project I'm currently working on: http://www.mycncuk.com/threads/9328-...Parts-Required

Well the time has finally come... I THINK I'm finally finished!

I've decided to keep the steel end plates. I can get them cut for free (which is a big plus) and I'll paint them to help prevent bi-metallic corrosion.

Looking good now.

The X axis stepper motors have the adjustment slots horizontal - will this actually give you much belt length adjustment? Any reason the slots cannot be vertical?

Good spot! I just checked and only have 3mm of belt length adjustment... I'll make the slots vertical!

Have you thought about just using one belt and one motor and drive, I use two motors but quite a few on here use one as it is easier to home and stops the problem of racking etc. Just a thought!

I haven't but I suppose I could easily use one keeping the same design. In fact, I'm not sure how I ended up with two motors in the first place...
