Last Sunday I set a rule for one of my Wemo modules to turn off the printer at 10:00 AM.

Well guess what! I forgot to turn the rule off and this Sunday it turned it off in the middle of a print. I know you can pause a print and resume it, I've done that before. What would be the procedure for resuming a completely stopped print? Would I just need to modify the Start script so it doesn't go through the priming process and set the start printing height to whatever I need? I'm terrified I'll send the head into what's already been printed.

That got discussed a bit in this thread

If you can figure out which layer it stopped on, you can restart it at that layer in S3D.

im sure there are ways to figure out layer and restart from there but its alot of figuring and anytime i have done something like that i end up with a gap or a poorly bonded layer where it restarted. what i end up doing is just taking a measurement of the part in the z then i drop the model on the bed in s3d by that amount so only the unprinted portion is printed. i remove the partially printed model from the bed and just print the new piece and glue them together.

I've done exactly what Jimc is suggesting many times and it works well. It's the easiest workaround that I"m aware of. I've also gotten the printer to resume where it left off (once), but it's a LOT more hassle.

Thanks everybody, I reached the same conclusion earlier. I just restarted the print a little while ago. Can't use glue on this one as it's designed to hold an expensive piece of equipment and don't want to risk it coming unglued.

I just failed a print (was trying to pick a piece of plastic off the Z-screw and the bed moved fast and pinned my hand and lost steps). After that mind-numbing stupidity I had a clever idea. Measure what was already printed, create a new part file for just the unprinted layers, but then **Here's the good part** stack something on top of the Z-home screw that's the same height as what's already printed then just start the new print. It will beautifully continue where it left off with minimal fuss. I just did it now using an adjustable parallel to set the spacing and it worked great, you can hardly see the joint. I've ordered a wide thumbscrew to replace the z-stop screw and in the future I'll just pile gage blocks on top to set the resume height. Easy. Works Great.

cheers,
