y axis motor mounting suggestions

I already did that last night Dean :) what thickness do you use for the mounting brackets? Currently using 15mm

Yep, that will work nicely. Even 10mm works.

side note on the plates for the BK bearings, if you look at my pic you'll see the plates actually lift the ball-screw just above the profile, this is so the ball-nut housing will attach directly to the X-axis bearing plate rather than using a drop-down bracket.!

do you have a pic showing the ballnut housing position Dean? here is what mine looks like but it has a plate hanging from the bearing plate for 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? picture is below to show what i mean.

thanks

You could put a shim 1.5mm in the gap or machine the BK and BF mounting plate 1.5 thinner.

Thanks Clive probably easier with shims then.

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

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
