belt on belt/servobelt

[GEOFFREY]

Does that mean it acts like rack and pinion? G.

Yes

that is a link to the commercial version. belt stretch is limited to the amount of belt it takes to mesh with the bottom "rack" and go over the pinion so it should greatly improve a belt system. zero backlash apparently?

Kind of hoping someone else has done this system and can warn me of the pitfalls ... but if not.. ill do it and report back.

I built a prototype, but never tried it out. I decided to re-design it to be stronger and handle more power.

I am looking at using a servo-belt at the moment, could you give any pointers as to how you designed this.

What belt you would use? T5 or HTD5?

Have you considered to cast the belt on the frame side from epoxy resin?

[johnsattuk]

Would be nice if you could buy steel rack with T5 teeth, perhaps stack some laser cut ones

[Ger21]

HTD5 won't work, it needs to be T5 to mesh with itself.
