Warco WM16 Conversion

Just ordered T5 pulleys and belts in sizes 14 tooth for the motors, 28 tooth for the X and Y, and 42 tooth for the Z. So I have 2:1 on XY and 3:1 on Z. Went with www.bearingstation.co.uk as they have a "price match guarantee" and were cheaper than the trade prices Brammer and RS give the company I work for.

Out of interest, how did you find the accuracy using the standard lead screws?

Might be too late but this site is very cheap for timing belts, lots of pulleys too:

I've got most of my belts from them.

My Vertex HV6 rotary table works well as a 4th axis. I just made a mount for a 1nm motor on to it from a piece of 3" aluminum bar - not difficult to do at all. Wear on the worm drive might be a problem though.

Hmmmm, they be very expensive I'm afraid! I paid £3.01 each for T5 x 15 x 14 teeth pulleys and they're £7.76 each on fish4parts. The 42 tooth was £6.94 on bearing station and a whopping £16.69 on fish4parts. Need I say more?

I've only got a 3 axis kit at the mo, but the facility is there to add a 4th. I was also a bit concerned about gear wear...that is why I mentioned using an industrial gearbox in a previous post. Rotary table and 4th axis is going on the back burner for now as I have to do!

You didn't mention the performance of your standard lead screws. What was accuracy like and how much backlash compensation did you have to set in EMC?

I was referring to the timing belts being cheap - not the pulleys!

I'll post more later, busy at the moment.

They didn't seem to have the belts in the sizes I wanted. My dearest belt was £3.18. Must admit I spent a couple of hours Googling before settling for bearingstation though.
