    I've built and still use a machine in roughly this layout although my components are not near the quality proposed here.
    When in use it's footprint is larger than an equivalent moving gantry but...

    Re: Reinforce X2 mill

    If 1 inch steel plate isn't up to the job the plate becomes stock for my larger mill, nothing lost.
    My guess is something else will start deflecting first and the extra mass may do some good....

    Re: Reinforce X2 mill

    Here's a mod I started on my X2 but never completed. The idea was to have bolts or set screws coming in from the sides.
    Obviously I've done no testing.

    disclaimer: I rarely use Windows and have never used Candle. I'll assume Candle is a sender for grbl.

  9. Re: What did I buy? Old machine, new tech, take a look.

    If it's a Kerk lead screw it will have some form of anti-backlash. You could ask the seller the screw/nut model # as Kerk has several.
    My preference would be a ball screw over acme.

    I looked up the specs of a 3018 and read dimensions of 300 x 180 with a cutting area slightly less than the machine dimensions.
    Is your machine larger ?

    Table locks are the little levers that can apply pressure on the gib strips. Your manual may call them by some other name. Unlike the acme screws in your mill a ball screw has very little friction...

    To measure deflection a dial indicator would be handy to narrow down the source. My guess is the v-wheels with their stand-offs are...
