Printing from SD - castle fail

Just got the Mk2 setup and have tried twice to print the 17 hour castle. In this last attempt, at some point during the night, it seems that the extruder d was unable to keep pulling filament from the spool. A simple push down of the filament got it feeding again, but I'm not sure why it stopped several hours in, and am also wondering if there is any way to resume the print that is still on the bed, though I have no idea what line of code I would resume from!

Thanks

Re: Printing from SD - castle fail

Hi Matt,

if the piece that you have, is Ok, then you could measure the height from the bottom to the layer where it stopped printing and the edit the STL so that it only shows the part that hasn't printed...

I randomly deleted the first 20mm of the model and got this

then I deleted another 20mm and got this

I saved the above as an STL, and sliced it in Simplify3d at 0.2mm layer height and it looked a bit like this.

the first version would be easier to graft than the second height... because there would be fewer separate parts.
however your graft point would be fixed to what ever the original print finished at.

you would hve to remove the original print from th buildplate and print the remainder off the buildplate.
this means that there will be a little deformation of the bottom of the second print, but you should be able to dress this out with some abrasive paper on a sanding block....
hope this is helpful.
regards Joan

Re: Printing from SD - castle fail

Obviously you would re slice the remainder of the model in your preferred slicer at the same layer height as the original mode,
I enclose the cut parts in 123Ddesign format, STL format and Gcode format
in case you want to have a play with the idea.

Thank you for the help. That seems to be a viable way to move forward in this situation. I was going to ask to what extent I had use abrasives on PLA (there's a lot to learn coming from CNC routing to additive printing). What I can't figure out is why I'm having these feed issues so late into the process. I did the Adalinda dragon yesterday and everything was perfect until right at the very end when the printer seemed to be unable to continue feeding, even though it had been going fine for 6.5 hours. Once again, just pushing down on the filament after the failure allowed it to keep feeding, but it was too late. I've heard that the stock spool holders for the Mk2 aren't ideal. Do you know if there are updated ones posted somewhere that are better? Could that be all it is?

Thanks
