You want closed-loop motors.
I guess if your really were that crazy you could put a set of digital scales on the X and Y axises but that seems like overkill. Even high end CNC doesn’t do that. Regular calibration of your zero point along with decent stepper motors means that you can regularly get within 0.001” repeatability on these machines.
That shit's a firetrap.
You don't need absolute accuracy, you only need relative accuracy. That's why you only have to level the bed relative to the print nozzle, not to the ground or to anything else. As long as your initial layer is accurate and there's no mechanical deficiency in your printer, your print will come out proper
You're thinking of the A8 (which didn't use to have thermal runaway enabled in the firmware)
Did not know that.
Companies do dumb stuff like that all the time. Hell, Chevy kept making the C/K after they were discovered to explode in pretty much any side impact. They figure name recognition is more important than positive press, and usually they're right
Can't expect great marketing from a small Chinese company.
In fairness to chevy they actually burned just as much as other trucks. That line was peddled by NBC and got them sued by GM. Turns out it was staged with rocket motors and multiple reporters lost their jobs over it.
Despite the Dateline controversy, the side-saddle fuel tanks on the C/K were much more dangerous than competing trucks of the time, though its a testament to the bean counters at Chevrolet that they still paid less in settlements than they would have to put protective cages on the tanks
With relative accuracy, won't errors accumulate? I've seen this when I look at prints - inside each layer, the tolerances are tight, but each layer will be displaced by some very small amount, so the XY tolerances are going do be dogshit across the entire object.
That's not quite relative accuracy. If you're talking about layer lines, that's inevitable, you're either going to have to sand those down, torch them, or deal with it
Thank you, I needed something to break the SLA printer's virginity and Voyager seems like the perfect one
Pretty much any printer you buy can be upgraded to do the things you want. At that size, unless your budget has a comma in it, you'll probably be bonding parts. I just stuck my keyboard on my Ender 3 (admittedly, a small entry level printer) and it doesn't fit in any dimension.
Check out this video WRT the 3-D printing BS. I work in the manufacturing sector and I can guarantee that if Congress decides to ban 3-d printers the knock on effects in manufacturing will be enormous. Off the top of my head, good luck getting a hip implant that is FDA certified. Almost all of them are 3-d printed for weight and material savings. Titanium ain’t cheap.
