I have bought Rowan's kit, payed extra customs fee, and I also bought 0.9 Degree Nema17 Stepper Motor 11Ncm(15.6oz.in) 20mm Nema 17 Stepping Motor 1.2A 400 steps, as well as 4x SKF 608 2RS BEARING 8 X 22 X 7 BRAND NEW and now I am choosing right PCB for onstep upgrade... Hope it will turn up to be nice astro set

Hope all of the members in this thread are doing great! I recently bought a black EQ6 with pulse motors made in Japan, with an old external controller Boxdörfer MTS-3 SLP, so no goto functions. I wanted to upgrade it to Onstep using this Roman's board https://oshwlab.com/hujer.roman/onstep-for-eq6 But before that, I want to convert it to BELT driven pulleys, but since kits are over 150€/200€ I wanted to buy 48:12 that can exactly match the case so I don't change anything on pulleys nor case. I know that the axis diameter of wormgear is 12mm so the Bore Diameter of the pulley must be 12mm, and the maximum width is about 9mm in this case, so the maximum width of the pulley can be 6mm for the same belt of 6mm. The OEM pulley diameter is 39mm, so the one that will fit with the belt must be about 36mm if I am not wrong. And max-width of all pulley must not be over 15mm with is reserved on worm for the pulley. But having searched on the net, I cannot find any pulley that will be straight plug and play... Can someone help me with the pulleys and belts, where to buy them? Thanks in advance... p.s. I have read all the thread more than once...
