You could also remake the top plate wider so the you bolt the ball nut plate down from the top and adjust it with slots in the top plate

I think Dean meant something like this. Extend the bearing plate rearward, rotate the ballnut around its axis 90 degree and bolt down through the plate into the ballnut housing

also how do you guys solve issues like the ballnut housing being 1.25mm away from the plate its supposed to bolt on to? i have gone of the measurements from bst automation and i would of thought the ballnut housing along with both bk and bf ends would all be level with each other unless something has not aligned right in cad?

Sorry, don't have a picture showing that part clearly... But it's not rocket science either.! The top bearing plate extends out just past the ball nut housing which as the mounting holes facing upwards to meet the plate, there are slots milled into the plate to allow adjustment. Then between the BK bearings plates which have slots, you have adjustments in both directions.

Ay! some of the stuff you come out with is rocket science to some lol. but yeah this does make it sound simple now. pic below shows what i was going to do but yours is much more simple

thank you mate

just a quicky

do these new and improved closed loop 5nm+ motors allow for extra weight to be added on the gantry? not that i want to add extra weight but this leads onto my last question. between the top and bottom bearing plate would there being any advantages to having a solid plate attaching to both of those or would it hinge things? its extra weight but if it will do nothing but add weight i wouldn't want to have it.

Thanks again
