I am 32 hours into a print and about to run out of filament. Is there a way to pause and switch to a new reel mid print when running on the SD card??

If you have enough filament and time you can fuse the end of the old to the new filament and help baby it through the extruder. I had to do this last week and it worked fine. You can slow the print way down using the LCD controls to buy some time. Not sure about pausing - that would leave the hot nozzle near the print where it will melt.

If it doesn't run out before I get home ill do that. I'm at work watching the printer on my cell. 3 hours till quitting time....man I hope it holds out until I get home.......

If you're printing through rephost, hit the pause print button and immediately move the hot end print. Doesn't matter which direction. I usually just hit pause and then hit the move x+50mm once or twice (assuming I'm in/near the middle of the bed). Once the head is off the print, you have all the time you need to change filament. Feed it through by hand until it starts flowing a bit, and then hit play/resume. It will automatically go back to the point on the print when it paused.

I'm on the SD card...my wife does strange things to the computer when I'm not looking. Last week I was 20 minutes away from finishing a 10 hr print and went to bed.
When I got up in the morning there was my nozzle stuffed into the part, on the lcd display... "Killed". So I'm on the card from now on....

You know, some one needs to incorperate a digital scale into the spool holder that ties back into repetier so it knows how much filament is left, how much the print job takes, and can say "yo buddy" there aint enough filament to do this job......
Im home now, just questioning how much filament is left, and how much needed to finish....

Or, you could figure out a setup where the end of the filament for each roll can be attached to a new roll, leading to an endless conga-line of filament fun.

You would have to know the tare weight of the spool. Unless your vender is spot on and gives you the weight of the material and not the weight of the spool and material.
