these should be in place if you are doing the 3.0 to 3.1 upgrade
M8 wrench for the nuts, make sure you don’t loose any parts
use a M8 wrench (spanner) and be very careful not to loose parts of the stack
if you are upgrading from 3.0 to 3.1 most of these steps are skipped. I’m using my old endstops will update if that is a problem.
I skipped to step 7
i followed the order of the instructions, but had to use a large pliers to seat the bearing when it was placed on the support.
Also curious what distance from the top the bearing should end up. No real instructions on that
The new system seems much tighter than the old metal ones. I could not get the front idlers to thread even with a zip tie, I removed the M6 x 10 bolt that fastens from the back and was able to get just enough give to thread the belt using the zip tie. I had used an old piece of belt with the original 3.0, but that is no longer an option. It seems every thing is just a little too tight. I like the new roller system, but a little more gap could have been built in.
I noticed some slight binding and the x axis seemed to not be square to the top. I loosened the two bottom M5 x 10 bolts on each side and the top M5 bolts. This allowed the length to assume the correct size and then I squared it to the front extrusion. I used some tape to hold it against the front and tightened the M5 bolts This made it much smoother and corrected the skew to the frame. It is now very smooth and square.
I used a 5mm drill bit from the front to make the holes large enough to push the m3 screws through to the back - then a long allen wrench to start them. I had about 1 mm through the back before trying to mount them on the block
If you are upgrading from 3.0 to 3.1 the idler plates should be in place. You will not need them or 8 of the M6 x 12 Cap head screws and 8 of the 3030 Drop-in T-Nut - M6, as they are already mounted
The xy_idler_right_3.1 and left files are not in the upgrade package or on the https://v-core.ratrig.com/upgrade/ page.
I did find them at https://v-core.ratrig.com/printed_parts/... and downloaded the two files I needed. Now I need to print before I can proceed.
