New Roller Blocks

Are the new roller blocks compatible with the older style (from 2 yrs ago)? I have one that has a significant crack and would like to print a replacement. Not ready to tie my printer up for printing 4 of them right now.

If I remember correctly all 4 need to be done as the offset is slightly different, you also need the motor mounts. It is actually a big improvement though, you should start printing as soon as you get s window to do so.

What was the improvement with the motor mounts? I’m still using the old version as well.

Significantly reduced flex in the motor mounts, better restraint of the bearings to keep belt alignment in check.
