The build was pretty difficult due to the ridiculous size of the resistors and the belt itself. This will frustrate many. After I got it finished, it is just too wobbly and finicky. Lots o room for improvement here… Definitely a first generation part. I have already ruined one belt. And since I am still working out the calibration for my MakerBot, I haven’t yet thought of a good reason to even use the conveyor belt. I am enjoying the heated platform, but part are still slightly warping in the edges. This is hard, people!
