3020 / 3040 / generic chinese router accuracy

[irving2008]

Hard to quantify, but a delrin nut on 12x3 trap threaded rod, using a tap made from a offcut of rod, was about 0.05mm when new, and 0.08mm after 3 months or so. Its good enough for 3D printing, and you can avoid backlash altogether by always scanning in the same direction.

I could probably live with 0.05mm.

It would be ideal if more ballscrew ones arrived in stock before the end of the month, as they're all currently priced £1k above what they've previously been selling at :-/

I've already got a decent controller ordered, along with a touch probe, I just need a machine to connect them to!
