Thread: Moving bed - bearing spacing?
Threaded View

Hello chaps.
I have a 6040 style Chinese router with 20mm profile rails and ballscrews. Just having a thought here but thinking if it would be possible to squeeze an extra bit of Y travel out of reworking the frame, flipping the rails over on to the bed and having the bed move. I was also thinking this would open up the opportunity to have a bit of cross support under the bed to firm things up a little and help prevent sagging..
It all depends how far apart the bearings need to be spaced as to whether it's viable or not. I'm thinking the bearings could come quite some way inwards as the gantry would be fixed, and the far ends of the bed could be supported by some sort of roller system rather than just having a big overhang.
