#JournalEverything Just got the next #3DPrint in the series for the cannula puck holder going again. Looks like it is going to be one of those days. I started it off before I got breakfast, and did the sprouts, but I forgot to put the filament back in, so it was merrily running through with nothing coming out of the nozzle. So I had to cancel the print, feed the filament in, and start it off again. Watching it lay down the first few layers while I eat my porridge and drink my tea.

Sometimes I'm my own worst enemy: the filament was not mounted because a couple of years ago I added a bit of custom post-job #gcode to my slicer (I use UltiMaker Cura) to retract the filament all the way out of the Bowden tube because if it's left there for too long, it breaks up and is a pain to get out again - it's also wasteful of filament, and I have to disassemble the entire Bowden tube assembly. So I decided that the lesser evil was to add this ejection code, but if course I still occasionally forget to re-feed the filament at the start of the next job.

I guess what I OUGHT to do, it's measure exactly how much to reject to leave the filament just in the extruder drive, and add another bit of pre-job gcode to re-feed it again. But that would be too joined up thinking for me!
