CNC Router V1.0 (For Cutting Multiple Materials)

Thanks for the info. With a 20T pulley I should have around 5 teeth engaged with what looks like a quarter of the pulley.

On a side note, I am currently looking at my bed plate design. I have put in a recessed hole to insert a standard kitchen sink waste hole. Is this OK or is there a preferred method? Also wondering if to move it to the corner and tilt the machine towards it...

What ability have you got for machining the aluminium? If only basic tools like me then you could probably lose some of the pockets. Would help with adjustment later too ?

Hi Joe,

I'm going to put an RFQ up to get all the pieces machined. If only I had a mill to start with!

Word of warning before commiting fully to this route.? Make sure you can buy a long enough belt of the shelf other wise it means having custom length belts made. Not a Big issue but still worth thinking about now.

The available belt lengths may also mean changing the location of the tensioners so work out the belt length needed for how you have it drawn now and see if belts are available that will work.

Oh Happy new year.!

Belt comes in at ~1.56m. Ive used this place a few times and they have belts up to 2.5m:

Happy new year everyone! :)

I only went for more idlers to keep the belt beneath the extrusion...maybe I'll have a re-think.

On a side note, starting to look at my electronics setup. I think these motors look reasonable?: SY60STH86-3008*

I've gone with your suggestion Dean but kept the slots in the plates so I've got flexibility in the future.

The cover needs work but looks like this now. It's starting to feel like the ends in sight!

Happy new year chaps

[JoeHarris]

reading this and the recent thread on controllers is tempting me back to the 3 stepper and belt option! I can feel another redesign coming on for 2016. Good luck Looking forward to seeing this project become a reality...

What plate thickness have you got?

[JoeHarris]

I have counterbored m12s into 20mm plate. The 8mm left between the head and the extrusion is plenty enough.
