I have been trying to remove the GT2 timing pully https://www.lulzbot.com/store/parts/gt2-16-teeth-timing-pulley from my X & Y axis motors on my TAZ 6 in order to adjust it for some motor vibration reducers. I was able to remove the X axis using a 1.25 mm hex wrench with a little work, but the Y axis motor’s seems stuck on. The set screws are either stripped, the threads in the socket are stripped or both. I tried a fresh, unused 1.25mm wrench, with no change.
It would be nice if that set screws used a larger wrench size, like 1.5 or 2mm.
So would anybody care to recommend a better timing pully replacement that would be easier to adjust, with perhaps larger set screws?
