My M5 hardware will not be here until later today, so I went to ACE hardware to get some 3/16"x2.5" screws since they are not too far off M5 (4.76mm) & they ended up being #10 which is the same as 3/16". I was initially thinking #12 were the same as 3/16" & figured since this is on the idler & the belt is pulling up, a smaller diameter probably doesn’t matter for this use. Of course, #10 is the same as 3/16", so it didn’t make much difference with the M5. In putting it together, I needed to rotate the 20T drive pulley around in the motor. I had it rotated with grub screws to the outside before. When I reprint the tires for 25mm wide belt, I will move that tread another 2mm out to make sure it clears ok. The motor wheel plate I printed 6mm thick & the outside plate 4mm thick. I was thinking I could go a little less than that but seems like motor plate needs to be 6mm thick. It was initially a little tricky getting that tire belt on there but putting free wheel on last makes it a lot easier. I have to reprint the idler pulley with limit switch on it where it connects on top of V-Slot before I can test this. Those wheels do not flex at all thanks to Jamie for that idea. Here is photo of it together.
