  1. Re: Cheapest wheel driven linear rails (skate bearings inside rubber hose)

    So are you talking 36x36, 36 x12? What are you wanting to cut? It looks like you are mainly using metal parts, and hardware store parts, what do you have for tools or have access to?

    I gave...
  2. Re: Cheapest wheel driven linear rails (skate bearings inside rubber hose)

    Hey Arashb,

    I think there are a lot of factors that go into making a machine, skill set, time, budget, what you have access to, and what you expect the machine to be capable of. Designing cheap...

    Re: Yet another cheap CNC build

    Agreed, that was the plan, after I get the spoil boards on and leveled I should be able to move it up a bit. I may need to recut the Z axis face plate to be a bit longer, the current version worked...

    Got around to actually measuring and trying to address the flexing of the gantry today. Verified it is the twisting of the plywood that is allowing the router to be moved up to 45 thousands when in...

    If you look at my website you can see I have been down this path a few times :) Just a glutton for punishment. I think if I had I gotten to this bearing design sooner I might have moved on by now....

    Re: Yet another cheap CNC build

    I am going to disagree a little bit, the steel angle for the rails and parts for the bearings including the screws and nuts work out to about $80, I think a set of cheap SBR16 or 20 rails and...

    Here is a selection of what I have done with the 2x2 moving table version I built, unfortunately I have gotten out of the habit of taking pictures so there aren't too many.

    Re: Y Carriage

    I also noticed you have washers on the 608 bearings? That would also account for the nut rubbing... the 1/4 spacers you made will adjust for that.

    It sounds like you are having a lot more trouble than I had when I built my 2 prototypes. A couple of things to note.
