Thread: idea for linear belt drive
Had a look this morning and last one has sold.
Still to find pitch and get pulleys
My comfort zones are fairly well tuned, I always 'know' what thickness of material to use, what bolt size etc. But obviously I must now consider adjusting my stepper motor zone, possible my feed rate zone to. This will require a degree of experimentation.
I have had over 1000 rpm on a disc-magnet stepper and a 40 volt driver but that is one whacky stepper motor.
Here is another idea which i quite like for linear drive, watch the video which shows the machine using chain and belt. I like the idea of keeping the chain/belt stationary and pulling the axis along on it.
I have the 220 Volt drivers so presumably it should go like the absolute clappers once I get the 48MHz dedicated cpu rattling the driver pins.
Thinks: Max step rate 40Khz, divide by 1600 steps/rev, 25 rps, 1500 rpm, 10cm/second rapids resolving 2.5 microns
No, I'm not brave enough either :rofl:
i have just bought 2 of the same belt from epay(thanks to john for posting the link for item on ebay,tried to reply my thanks but his post has now disappeared?!!!)
they were a bargain only £0.99 each,sadly postage was £5.99 each:nope: oh well cant have it both ways.
another step closer to my build.
Only problem now is to find the pulleys or drawing of wht is listed as an RPD8 belt. Nearest I have found is listed as RPP but no drawings so I can compare.
Good score on the belts.
Peter, I too did a quick scan. No info on RPD either. Maybe you can draw up the profle so we can compare it to HTD8?
