Hey! Long time no see. :D When you say sandwiched and backfilled, do you mean connected together back-to-back and then internally filled, or do...
High Speed Machining strategies are the solution to HP-limited MRR, not spindle upgrades. (I'm just gonna quote-reply this post forever, I know)
Better to use a point loading moment calclulation than a uniform-loading one, which is more suited to building construction than CNC gantries. I...
Easiest size to mount is 20mm because it's a full V-Slot unit width. 15mm are much lighter, though, and will handle far more loading than the...
2.2kW units do have ER20 options- that's what I have. At around 12lb, that's a huge difference vs your current spindle. That would work, but not...
Even a 2.2kW spindle is usually considered overkill for any of the OpenBuilds designs. 1.5kW and under is best- the wheels and frames can't take...
Step one of the design process: What does this do that a router template wouldn't?
Make sure the drivers are SilentStepSticks or similar, and add a little ducting to the window with a PC fan to help vent out fumes. Or build an...
A closed fluid loop is more or less impervious to gravity- mounting height shouldn't matter.
I'd use 0x84 Safety Door real time code with both parking and door input pin compile time options. You'll have to use some kind of intermediate...
Perfectly put- for cameras or CNC machines, it's servicability, not failure. Deflection and deformation are the usual enemies, not outright...
5lb doesn't seem like much for a camera rig. C-Beam weighs about 7lb, decent fluid heads about 4lb. 2lb would cover a tiny camera like an A6600...
I'd do it like a standard machine enclosure- painted sheet metal with acrylic (orange OD in this case) windows. That's my plan for when I get back...
I've thought about a project just like this a lot- tripods, dollied or not, no matter how many things you Magic Arm onto them, are inconvenient to...
Torque is transmitted through a screw to become a linear force. Force you need to push a cutting tool through a material. That screw also has a...
Gotcha. Much more reasonable. They'll look undersize but they should be fine even for the 2.2kW spindle. They're not- you'll likely need a dial...
I love a good scrap build. This is awesome!
Sounds like you're generally thinking along the right lines, except: I hope you got them on an amazing deal, because it's gonna be hell on your...
Grbl is using a TLO regardless of whether you set a number, just like it's using a WCO regardless of whether you probe a work zero. If you're...
Once upon a time, in between religiously reading RCM&E, I borrowed David Boddington's Building and Flying Radio Controlled Model Aircraft from the...
