Spoke to some timing belt companies, intersting stuff........

HTD5 pulley's and belt

Try ERIKS where i got mine from. It is an expensive outlay but comparible to screws, I will try and update my build log soon. Don't buy the rubber belt a complete false a oconomy, Time gets less and less everyday, i have to finish putting my southbend back together to make room to finish it off (tiny garage)

Have a look here http://www.technobots.co.uk/acatalog..._Cams_404.html for your pulleys and belts, this is where u got mine from, if you cant see what your after give them a ring, thats what i did. They are very helpfull!

Thanks, ill take a look

technobot do not do the sizes or open ended belt but they are very helpful

+1 on helpful!
AdCNC - Now that your machine has been running a while ... i appreciate its servos not steppers ... but any comments / after thoughts on belt size/pitch/width/type, gear size/material, ratios or the design you used to allow for tension adjust?

If you remember .. what were the specs of the belt + pulleys you used?

BIG THANK YOU!
*looking 90% like it will be SY60 steppers (48v BiPol Parrell) for 2x Xaxis ballscrews 1100mm long each hauling 35kg of Y + Z + router
