i can not seem to get my coupling inside the xz with the couplings they have some black plastic piece the stops them from sliding all the way down the motor for me to slide the bearing in. any suggestions. this is a v2 longmill
Hi Tristan,
I have updated the instructions here: https://sienci.com/dmx-longmill/y-axis-gantries/
You will need to put the coupler on the motor and the bearing on the Y axis plate before mounting the motor, then it should all fit together.
Best,
Andy
