CNC Router V1.0 (For Cutting Multiple Materials)

[biketrialsdave]

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...

There are pro's and con's for the two systems I don't think there is much difference in cost between the two.
.
With two motors you will need two homing switches and a controller that can do the slaving correctly and also have the alarm outputs on the drives working in case one motor stalls and then the other will rack the system.

Dean (Jazzcnc) usually uses one motor but I think on the machine he is now using it has two.
I use two motors and I am happy with it.
