Depends how large and depends what they're gonna be used for, but in general EVA floor mats would work just fine, stacked and contact cemented...
This means you're switching from a moving-carriage to a moving-rail Z axis, right? Not that you're moving the Z-axis to the gantry columns and...
Higher durometer polymer foams- EVA, extruded polystyrene, rigid polyurethane (tooling board), polyethylene (Kaizan), etc- are perfectly fine to...
Ramping into a cut isn't the same as a spiral pathing strategy, it should only be an inch or two long and not significantly alter the length of...
Yeah, CONTROL or bCNC are generally the most-used around here. CONTROL gets you direct support from Peter, but currently lacks things like G53...
Heh. That's what I suspected, but you never know. 141oz-in to the Nm, which puts your 0.4Nm around 60oz-in, which is right in the middle of the...
Forty Newton-meters? You sure about that?! The NEMA 34 on my cast iron mill's Z axis is... twelve.
Drill a couple holes in the side of a $99 mini fridge under the table with one large bucket of water in it? It's just plastic and styrofoam. Could...

I do have a manual mill conversion build thread here: Grizzly G0758 Benchtop Mill Conversion - may have some commentary or considerations that...

If it's plunging at one side of the tab, doing a full-depth cut, then retracting at the other side of the tab, that could absolutely be the cause....
Totally. Just need the extra piece of C-Beam, longer screw, etc. There should be builds right here on the forums that have done exactly that.
Linear rails, if preloaded, really need to be swept and shimmed parallel to within at least 0.0001" (0.0025mm) at every point along the full...
Even if you only tighten up the four outside eccentric wheels on each side, that should go a long way towards improving machine performance....
I learned the hard way on the laser that "I can build this for $250!" doesn't exist. It's been a great project and forced me to learn a ton right...
No matter how you do it, decent quality motors + drivers + controller are gonna be in the ~$350 range. If you went MiniMill style so you only...
MiniMill or C-Beam Machine, if you want off-the-shelf, ASAP, developed for you. I'd go C-Beam- it's gantry-style, so you'll get used to...
Odd. If it was definitely the belts it should have noticeably improved the results. Like I said, literally half as much belt to stretch/release....
Since I don't have Disney+, here's a screencap from a mildly dubious source (albeit right at the top of Google results :ROFL:): [ATTACH] I've...
