    Printed the guide springs with Taulman3d 910 nylon.
    Change the bolts that are in the screw blocks from 25mm to 20mm so that they do not protrude on the inside of the block.
    Fit 4x 8mm low profile bolts and 4x knock in tee nuts this allows the spring to move on the bolts as they bottom out on the extrusion.
    I have 2x on each side as it’s 1000mm x 1500mm machine, but I think 1 would be fine on 1000mm x 1000mm machine.

    Very nice - could I persuade you to post a copy of this in resources so it's easier for people to find in the future?
    Thanks,
    Alex.

    Great Idea, Unfortunately for me I don't have a printer, only CNC router 1500x1500.
    Are you selling these?
    I'd happily buy 6 and pay costs of Shipping to Australia.

    Hello OpenBuilds World!

    I've noticed there's a few solutions to the screw whipping issue. Here's a couple more links for anyone looking into it.

    Tony Thor

    Martin Skoog

    >>Great Idea, Unfortunately for me I don't have a printer, only CNC router 1500x150

    There's plenty of online printing services that should be able to help you. You may even be able to get it done at your local library or uni.

    Cheers,
    Ian

    Interesting solutions! Are you all using your screws in tension as well?
    Cheers

    Personally, I favor Tony Thor's method. Easily cut from a Delrin(POM), nylon, or PTFE block if you already have a mill. It's far less expensive and it'll also work with the thick sides of the Lead style setup as you don't have to go around the outside framing. And depending on your nut block style you may be able to implement it without loss of Y-axis length which puts it in the same realm with the original idea on the thread.

    I'm in the process of moving from a Microcarve cnc to a Workbee. It's not built yet, so I don't even know if I'll have any issues - but was just looking at whipping solutions - and I'm with Rick - I think Tony's method is the way to go...even though Martin's method looks cool.
