For cutting wood on my GT2 9mm belting-269 oz/in steppers…I use 500 IPM rapids…roughing up to 350 IPM in soft woods and 150 to 250 for hard woods.
For pocketing with a 1/4" bit with a low stepover (8%) and a ramped toolpath into the pocket, I am able to easily cut 1/2" depth of cut with a 1/4" bit in both hard and soft wood. You must have proper toolpaths to do this…
The belt clips are 12mm wide total but the slot is only 7mm wide. You could try to expand the slots by 1.5 mm on each side to fit the 9mm belts and some play. It’d only leave 1mm on each side of the clip but the clips are made from 1.5mm cold rolled steel.
I actually did this when I upgraded to 9mm GT2 belting. I don’t know if it will hold forever but it is still going strong after 10+ months. On one of the 4 it had a slightly jagged edge and it started to fray the belt there (go figure). After smoothing it out, it’s fine now. I used a Dremel to enlarge the slots.
ok I figured I would get a list together for when I eventually snapped the stock belts. First I want to lift it inch or so so I can add t slots directly to the wasteboard if I can find plates the Triquetra plates are out of stock
While belts are history for me as far as tension I did the following till the very end with fantastic results for such a huge machine. The logic in what I used to do should apply to any type of a belt.
Larger than what? The 625 2RS are identical to the Inventables bearings in Idler and Makerslide wheels. Idler seems based on the Makerslide Idler but with a center section of 5mm vs 1mm on the original one so they should be wide enough for the 9mm belts.
Yes was just a tinny bit, I was not even sure it first but that I seen them spinning when movie carriage without belts. If I remember right I just put then on a bolt and into a drill and ran them over sanding 3m block and was enough.
