Gantry advice please

[Crunch]

I was going to order from Fred at BST
He has offered machining the ends for pulleys.
He also offered better bk/bf bearings.
Is this the bearings you are talking about?

Thanks for advice

Yes those are correct bearings. Just tell Fred the f length you require but as I have said the ball screw length includes the f length . Its an easy mistake to make.

So just order say ball screw machined both ends 1610 x 1200 with f length of 30mm

(where 1200 is the total length)

For the avoidance of doubt my router has twin screws twin motors and the screws are 1450mm overall. Motors nema 23 . without any problems.

Are your ball screws 1610 or 2010 ??
How heavy is your gantry, roughly ??

1610 and about 70kg



there are two 1000x60x60 x5mm box section behind the front plate on the gantry.

Also you don't need the screw to be the full length of the machine
