You want the ROQ board described as
ROQ Registration Pallet Trilock Compatible Permanent 23x31.
This will put the 2 points at the front left of the print head the same as M&R. This will align with the bottom right of the spyder so that the points are all in the same spot.
ROQ has many variations of this as you mentioned that confuses things. Why I really have no idea. It’s just they started with then on the other side and it was only after they came into the NA market they developed a system on the other side.
The Danny videos are of the system that would not work with M&R. I suggest always getting the version that is trilock compatible. Resale value etc.
There is no difference in the accuracy. The main point is getting the permanent version of the pallet and NOT the adjustable. The pegs on the adjustable move .02mm because, well, they are adjustable. The permanent version doesn’t move. .02mm is the difference between dead on and having to slightly adjust.
Check out the second picture. You want the one on the left. NOT the one on the right.
DM me and I’ll give you my email address and send you some YouTube videos of the process. FYI it works just as well in the new M&R Digital Pallet system also.
