Grbl v1.1 Interface ยท gnea/grbl Wiki The realtime command "?" should send back a list of current parameters, including position.
I'd be open to learning about this as well. Once you get beyond the DIY handheld units or maybe the "bandsaw" style 2-axis manual or [maybe] CNC...
Glowforge calling itself a "laser 3D printer" has got to have confused a lot of people over the years
They get away with what are kinda sub-standard screws because they're multi-start; while the pitch is 2mm, the lead is 8mm, so the screws aren't...
I wouldn't use 12mm in a rotating-screw configuration above about 500mm or so. 16mm are stable to around 1100rpm at 1500mm, so I'm happy to use...
That's what I would do. An 1/8" steel plate or 1/4" aluminum plate. Just get ready to drill a lot of holes! Roughing-finishing is a much faster...
Have you looked at other methods of stiffening the gantry? This sounds heavy; I'd run the calculations for the Y-axis motors and see what kind of...
More convenient from a loading perspective, and more like a traditional manual mill layout. Your concern about torsional rigidity is spot-on,...
Nice! I tried to document as much as possible to show both the machine and my thought process behind it. Not much point in just showing a...
Yes. The weight would be spread out across all the ball bearings, and due to the rigidity of the two carriages, you could bring them closer...
Easy test: pull the spindle out of the clamp and re-run the program. Does it still do it? Looks like way too few wheels for the weight and...
Depends how much self-directed learning you do ahead of time. I'm generally of the mindset that you should understand the machines *before*...
Depending on your controller, limit switch placement is kind of irrelevant, as long as actuation is consistent. Ideally on a gantry type machine...
It's a drill press vice, but it has a mill-style X-Y table built into the bottom for precision positioning of workpieces for drilling. Since you...
Honestly for such a small, specific machine, I'd probably just buy a 5" cast iron drill press X-Y table for like, $60- they're all just knockoffs...
As long as they're all parallel to the top plate's main axis rather than its curvature- ie. you're staying within a half inch or so if the edge...
It seems workable. Don't put in more adjustment than you'll need, unless you're adding extra rigidity somewhere. And the belly of a violin is a...
The aluminum block mounts and centers the nut block, itself mounts to the C-Beam (since the fixed end nut block doesn't have 20mm C-Beam screw...
The mounted image in this post and the first image in the post after should help: M4: 1510SS Heavy Mk.I
Low rigidity hobby routers were never really intended to give great finishes on metals. Sanding/grinding and polishing are about the only way....
