Hello

[davo453]

Thanks for the welcome, a couple of corrections, the usual write in haste repent at leisure....

The steppers are Nema 23 (simple typo but big difference) and the router is a POF 50 (rather underpowered and soon to be replaced with a 1.5kw spindle).

The leadscrews are Trapezoidal 14x4 with 2 on the x axis and home made Acetal Nuts which have proven to be surprisingly effective with no backlash even after several hundred hours of use. The X axis is 1600mm and I don't get any perceptible lash, but it's not running at a particularly high speed, 1300mm a min is ok for my purposes.

I agree that wood (in this case plywood) is not the best material to use but at the time it was my only option. I now have several contacts and the budget to make one in metal but at this time this suits me so why fix it if it's not (yet) broken. However all of the upgrades I have done are done with an upgrade to steel in mind.

The machine is in the main used for carving in wood.

This picture is the only one I have of it in it's first incarnation, it was set up for testing and not totally finished but you get the idea. It doesn't look very much like that now though. I'll take a photo of how it does look now later.
