HTD Timing belt and backlash
I am building a CNC router using two 48" long Tolomatic belt drive actuators for the x axis. The actuators currently are using 1" wide 5M HTD rubber/fiberglass timing belts. After my initial tests I would really unpleased with the stretch in the belts. I am considering upgrading to a rubber/steel belt which should reduce stretch. The more I read about HTD belts the more that I learning that they are good for torque but not for positioning accuracy. I am considering switching to modified curvilinear (GT2) style belt but this would require I change my pulleys. Can anyone comment on the accuracy of timing belts and the different tooth styles (ie HTD, XL, GT2, etc).
Thanks!
Re: HTD Timing belt and backlash
Realise this is an old thread but I am in the process of designing and building my own belt driven router and had the idea to use two belts on each side of the X axis. Actually it would be a dual belt in belt drive on each side with the belt offset a little or two pulleys offset like a split pinion. I am going to try it with a gt2 (PU, steelwire) belt but want to use HDT5m 15mm steel reinforced PU belts on my machine.
What do you think?

I work on a new power tranmission project, purchased HTD 5M and GT2 from https://www.zzr-parts.com . Available in PU and rubber belt body
