My largest print. 40cm3, 16m filament or 3hr20minutes…
1hour passes without any issues or major design flaws. 15minutes later I get power outage in the house…f**k
Food for thought … A UPS would keep it up for a while but if you shut it down could you recover and pickup where you left off ?
The outage was instant…
Welcome to 3d printing…
Lol. I will print from a sd-card using an ups. If it is still alive.
I saw someone attached a 3D printer to a Quadcopter and ran it off hobbiest RC lipo batteries. I bet some makeshift low cost UPS could be made with one of those without too much effort!
As I have just embarked on a 13 hour print a $50 CDN UPS is starting to look like a good idea !
I have don a few 8 hour prints. I have not had one fail yet, but if you want to resume a failed print you need to be able to re-home the Z, which is a problem for most printers (if the printer turns off it will not know where it is in space)If you can re-home, you can measure the height of the print, then delete all of the G-code before that point, and you can save the print, i have done this before, it is alot easier then you think it would be.
Just 3h?
That’s nor a very long print.
+Camerin hahn. Good firmwares have a pause.
Raises the head, keeps bed warm but head cool.
Later resume by heating back up, lowering and resuming.
We put an UPS on our printer at work specifically for brown outs, which happen pretty frequently. This is also why all pc’s in the building have UPS’s as well. My home printer has none, so it just dies
@Marcus_Wolschon yes, i am not talking about a soft pause. i am talking about a lights out, power off for extended periods of time. Also with a long print, i prefer to move to the SD card, as it eliminates the communication between the PC and printer and makes the print more stable, as i don’t have a LCD and i don’t have it conncected to a computer telling it to pause, move up and away, the cool down isn’t possible for me.
I have a card inserted into my PrintrBoard - but hardly use it…most of my prints are small averaging about 1 hour. brackets, standoffs, any FPV related gem I can come up with.
The latest prints have been the biggest - me building an eggbot, but the print that died is a motormount for a 3d-foamie
@Ashley_Webster it is the only good reason i can think of for homing at the top. every other argument is self defeating, but that is a discussion for another day.
Or run it from a laptop plugged into the power. And youve got the battery in the laptop keeping the board running and it should auto pause.
That could work. I wish there was an export settings in repetier and slic3r
