CNC Router V1.0 (For Cutting Multiple Materials)

**JAZZCNC** · 27-11-2015

#1 Drill the Plate and screw from under side.

#2 Drill thru the upper extrusion and bolt into lower T-slots. Can add some Blocks into the slots to stop them sliding.

#3 If just bracing then 5mm steel will be just about ok, But personally I'd use 9.5(3/8")mm Aluminium so don't have hassle of painting etc plus steel on ali is not good mix.

#4 Can do it but it's difficult and not very effective unless high vacuum. Much better with Blown air and minimal Mist to clear/Lube chips.

#5 Simple holes at one end and angle the machine on bench using feet.

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!
