    Any thoughts on this design from all you guru's ?
    Will be using Mechmate home ground rails for x and y. The results some of those guys get are amazing (see mechmates forum for some amazing router builds) . rack and pinion of x and y. Will have a water table that can be wheeled in and out. Would also like to use it ocasionally as a router, I appreciate that there will be a fair amount of set up time to convert between the two. Will be using a gear a belt reduction on all axis approx 3:1.

    Havent even thought about z yet but it will have THC. Any thoughts here would be greatfully received.

    I have a candcnc plas pak 1a kit. Want to have it running by end of december latest.

    Cheers.

    Hi

    Looks fun, are the Y (long travel) motors going to be sprung into mesh or fixed?
    If sprung Im not too sure if some bearings running on the bottom face would be a good idea to stop the machine tipping under hard accel / decel.

    Keep up the good work

    cheers

    Sprung into rack. I wandered wether bearings running underneath might be needed. Would they "confuse" the sprung tension on the pinion ? if you know what i mean. Mechmate routers do not have the bearings underneath but then their gantry looks pretty heavy.

    Well here it is..
    Spent 3 months building this, now ready to plug in.
    Will be building a water table to fit under underneath.
    Using a plaspak 1a system from candcnc which i managed to pick up on ebay as an uncompleted project.
    Now I have the big Mach 3 learning curve to conquer.
    Sure hope it all works!

    Looks good mate, well done on getting this far!

    I'm liking the sprung tension on the pinion, never seen that before.

    That's looking a good 3 month work ads...! When you've got it all tuned up it'll be a nice robust machine.

    Just a Q: What are the Vbearings running on on X and Y? It is the proper machined rail, or have you found some alternative (angle iron, or something)? And did you use eccentric bushes to pull the bearings onto the rails, or some other method? Just curious because my next machine will probably be using v bearings.

    Anyway, looking good!

    X is running on home ground rail (an angle grinder on a skate) check out Mechmate forum they build some fantastic routers.
    Y is running proper ground rail.
    yep, used v bearings on eccentric bushes from superior bearings in USA.
    Had motors running today, 80% satisfied. Running out of time now as I wont be allow to play with over Christmas!

    christmas is past!!!:naughty:
    how is your build going i am hoping to build same sized plasma/router but racks etc to expensive,thinking about belt drive(see my linear drive thread)
    where did you buy racks etc and how much if its not to cheeky to ask???

    Cutting metal now. Big learning curve here!
    Have already sold some cut plates off the machine.

    The x axis rails are ground angle iron, have a look at the mechmate for info on this. Don't dismiss the idea as mad and bound to be inaccurate! Have a look at what the lads build on the mechmate.com. The Y rails are no2 ground v rail from Eurobearings. The V rails from superior bearing in USA. The geared racks from WMH bearings Tamworth.
