It's for a heavier and faster machine than a LEAD, but I also don't believe in "too heavy" for benches: [IMG] (From: M4: 1510SS Heavy Mk.I )
This entire issue should be solved either by A) increasing the $27 pull-off distance to a not-activating-the-switch distance, or B) setting...
The "Brains" board of the BlackBox is electrically an Arduino Uno- identical components and firmware, just a different physical orientation. I...
When the power company ran power to the house and the electrician installed the weather head/meter base/breaker panel, they also hammered a (or...
I'm not really sure what's missing there- that's the link to the page with the wiring instructions?
gnea/grbl ?
At the breaker panel/meter box, yes, but you'd just use the regular mains ground where they already did this when they put electrical in the...
The question is whether the tape is off or the tape measure is off. Tape measures are off by 1/16"-1/8" over 36" consistently- I know this because...
Cable gauges relate to current-carrying capacity, and ratings are modified depending on how long the run is and how they're jacketed and routed....
Marlin is a printing firmware. grbl is a machining- mostly- firmware. The board that'll print the hardware is not the board that you want to run...
I have closed-loop steppers on my machines and love them, wouldn't use anything else except servo... But I have open-loop NEMA 17s on my laser....
Hmm, maybe I didn't explain all of my thinking in the simulation posts earlier. I partially addressed it in another thread here: So twist, due...
I'd aim for around 0.1mm at worst. A thou or two, ideally. 0.5mm is gonna start flexing/jamming things as you go, especially near the mounting points.
The beams look great in place! They're each held in by 8 screws for now while I figure out what I'm doing. Pulled the 6" relay rack post out to...
1) Run NEMA 17s on 24V. 12V gives you pretty anaemic performance. 2) 1.68A is per phase, and if you're microstepping you're using both phases...
Essentially, yeah. But there are multiple degrees of freedom to think about here. Not just vertical bending in Z, but also bending in Y as well as...
I ended up going from a "sandwiched" gantry to a "pillar bridge" gantry with a longer gantry resting on the columns for this exact reason. A...
Love this, reminds me of my laser build. The satisfaction of machining your own hardware is immense (if a little on the slow side sometimes) Is...
No kidding! Even buying them inexpensively from Amazon it adds up, but averaging forces over a lot of fasteners is a time-honoured technique....
If I were starting a printer build from scratch, the first thing I'd do is determine the build plate size. Since what matters is the bit between...
