Tension problems with the Chaotic Lab CNC Z-Drive

Hello,

I have a problem with the CNC Z-Drive from the Chaoticlab CNC Kit. I have assembled and mounted everything according to the instructions. Everything is also OK with 2 motors. I cannot tension the belt on the other two motors. The Z-Drive and the motor are already so close together that I can no longer tension the belt tensioner.

I have already disassembled both Z-Drives and reassembled them, but nothing changes. The belt is already so tight that it can't be tensioned any further.

Has anyone had this problem before and have any tips for me?

Many thanks in advance,
Dirk

I don't know how they work.. but any way for you to mount the motor a bit further away from the pulley assembly?
