This was definitely a mistake, the screw needs to be 40mm long. I have fixed it now.

Interesting, my cable is a genuine Prusa cable and came in red-white-black. Anyway I have switched to “The red cable should be on the left”. Thanks!

I have not detailed the software configuration yet but you have to disable the fan check in the menu of your printer. Should be in “settings” menu.

This is only for MK2.5(S) or MK2(S), not necessary on MK3(S).

For now they are in beta testing for my Patreons only. Will be public when I have enough feedbacks.

My belt clamping profile are definitely a little on the tight side. It is very hard to find the best size as the belt have important thickness tolerance.

Correct, I will redo some screenshot to make things clearer. Thanks for mentioning it.

Cool idea, thank you!

This is not normal, make sure the belt is correctly inserted in the X carriage (completely pushed in). Also check the idler is not wobbling, belt not damaged and no excessive tension is applied to the belt

It is extremely hard to get the X belt in the middle due to how the X axis is structured. I have done several improvements compared to original axis (like screws on steps 5 and 6 here) but the X axis is always going to be unstable unfortunately. In general you get the opposite effect, belt is going in the direction of the extruder.

Better without mainly to avoid people using the textured sheet which might not be very reliable.
