MDF CNC Router plans / parts for home build beginners

[Lee Roberts]

Hi Steve,

It’s looking good, I’ve not replied but I’m following :).

I think one thing that sticks out as a possible concern to me is that, when I built my rockcliff machine the 13x13” Y Table (the bit you put your work on):



Started to bend and go banana shaped in a very short amount of time. I did have an unnecessary pocket along the length and I think this helped it on its journey to becoming banana like. My concern is that yours may do the same, an option to stiffen it all up maybe to add some ribs under the table the same shape as the Y Axis ball screw floating end plate in your model.

I would prefer if the machine was a flying gantry type as well, if you think about it the design at the moment needs a bigger foot print then if it was done as a flying gantry type.

So I’m thinking, take off the support footer for each of the gantry side plates, mount them at each end of the Y Table (possibly even double them up), use two lengths of MDF that run underneath/in-between the rails and Y Axis plate, this would then hopefully give you the clearance for the ribs.

Just my observations mate, what do I know :confused:

O nice Z Axis design as well, i like it
