Re: M2 or M3SE

this was half the price of a new one. A friend picked up an Ender 3 Pro in January, added a couple hundred bucks of this-and-that, and, after many misadventures, was delighted with the results. All in, it cost maybe 20% of a new M3 with a good out-of-box experience. Which, right there, tells you wh...

Re: M2 or M3SE

Opinion follows … Based on watching folks I know who own various printers: buy the M2 or M3. To a very good first approximation: Everybody else seems to have a printer that works great after replacing this, that, and the other thing, then spending considerable time & effort keeping all the parts fly...

Re: .75 Nozzle on V3b

push this as far as I can get away with The fundamental limit comes from the heater's ability to bring cold plastic up to extrusion temperature inside the 20 mm hot zone. Using airscape's example, the extruded thread is 0.5 mm thick × 0.8 mm wide = 0.4 mm², so laying down that thread at 50 mm/s mea...

Re: M2 Not homing correctly y axis

it only moves a couple of inches back and stops It's a mechanical problem: most likely, the linear bearing track is full of dust and congealed lube.

Re: Covid Mask

Your (presumably) virus-laden breath would vent directly to the open air and sprinkle droplets over everyone in the neighborhood. Definitely not the kind of mask we need right now. Back in the day, though, we used vented ...

ABS filament print very clean horizontal lines per layer nozzle size 0.5mm, layer height 0.4mm I have my extrusion multiplier to 0.95 First of all, the extrusion mulitplier is not a free variable.

Re: M2 lost motor control

manually move the bed position Betcha you jostled the printer or the power cable when you did that; I have one of those t-shirts … TURN OFF THE AC POWER, then check the motor power connector on the RAMBo board.

Re: Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting

an immense amount of force to finally get it to break at the damaged area. The thermistors don't draw any current worth mentioning, so as long as there's a single non-quite-broken strand of wire making the faintest contact, it'll (seem to) work (intermittently) just fine. Pulling on the wire might ...
