I am looking to engrave 4 ft x 3.5" planks of wood to engrave several coasters at once rather than doing them individually on the MPCNC.
Would the Lowrider be able to provide enough accuracy for engraving something like this? I saw some posts about meshleveling and surface leveling-- would those options get me where I need to be?
I plan on making the Low Rider large enough to accomodate half sheets (2’ x 4ft’).
It’s oddly not symmetrical. So if you’re following the wheel axis, the wheels follow the surface. So I would expect high accuracy in Z. The other way, there the gantry is riding on the pipes, the Z is dependent much more on the flattness of the table and really, how parallel the table is to the tubing.
You can surface a spoil board instead of mesh leveling and you should be able to get good results.
Makes sense. So as a ‘best practice’, I should make the longest part of the work piece parallel to the wheels?
I think that’s the only way they’d fit anyway, so I would’ve accidentally done this correctly!
All machines are different, but in general, yes. If you were talking doing floor board trim or something, I would say you need to come up with a guide or way of homing the x axis so it’s the same distance from the edge each time, but for just surface area, as long as everything is bolted down correctly and you are getting square/round shapes, you should be fine. The belts do behave differently at the extremes, so judge accordingly, probably don’t go to the very edge…
Cheers!
