You're probably gonna have to define what you mean by light commercial, because you can buy a 4x8 light commercial router direct from China for...
Rack and pinion is like rails and screws. Cheap to import directly up to 1500mm, then gets really expensive. Upside of rack is that you can cut or...
gnea/grbl In laser mode, output power is dynamic under M4. Short moves are primarily acceleration and deceleration, which means that the laser...
The Nichia diodes in DTR Laser copper housings with G-2 lenses are the way to go for sure. If you have a 6-8A driver that works well already then...
Thanks! Appreciate it. You ain't seen the half of it- looking forward to moving to a 6W+ diode, because that thing can haul ***. Belts and...
[MEDIA] until 17:05 shows my bearing block boring and fitting [MEDIA] (24:17 in the same video) shows assembly of the unsupported shaft, you can...
Juddering at speed is usually improperly set eccentrics on the wheels.
Maximum rigidity is achieved by building basically twice the machine you want, then using all the excess space to allow wheels/bearings to run...
Ah, should've led off with the diagram. I had envisioned something completely different. Now I see what you mean, though that would be axial...
Looks prone to racking. For rigidity you want sets of wheels a distance apart (the further the distance, the better, limited by the frame's rigidity)
It'll actually be subject to a torque load- depends how far out the 16.5kg is mounted. The rail will be fine, not sure about the wheels. ~40lb...
You can buy the rails for like $50 a set on eBay. The rest is just mounting them. Admittedly, that's not the easiest job in the world, but if you...
Table saw?
Yeah. If I were doing a "real" spoilboard, I'd seriously consider going the route of plasma cutters and using a whole bunch of 2x4 studs mounted...
OSB is cheaper here too, but MDF is flatter, more uniform for cutting into, and better helps absorb vibration than a more rigid material.
That's what happens when you're not cutting a proper chip with sufficient evacuation- you have to cut actual chunks of metal, and then get them...
Yeah. There are some fancy sine-based stepper drivers out there that are apparently super quiet, but the only steppers I've heard that are like,...
Theoretically? Spindle power relates to volume of material removal per minute. Given that number, a chipload per tooth (which, depending on...
I'm literally running the mill right now using LinuxCNC's tool offset tables without an ATC. :thumbsup: M6 is my new best friend.
I use LinuxCNC, NEMA 34s and ballscrews on my Grizzly conversion, so I can't comment much there. Most of those grbl settings will really need to...
