Thanks for your reply, I understand your process, thanks for explaining it.
One reason I was interested in your modification was that my carriage assembly was binding . This was because the spindle plate was too close to the delrin nut and was actually pushing it and putting a lot of pressure on the ACME screw. The way I fixed it was using longer screws and more washers until the delrin nut could be slid behind the spindle plate without pressure.
I think that with your assembly one could adjust the distance between the plate and the maker slide by adjusting how far the v-wheel screw is into the last 2 nuts and then tightening the last 2 nuts against each other creating the perfect spacing and without having to try different combination of washers to obtain the optimal distance between the center of the v-weel and the spindle plate.
I will try this as soon as I can find some longer M5 screws.
Thanks again for taking the time to reply.
