History - Day 3

After the good chess piece.  I tried and tried and tried and tried to get anything to print.

My 14 year old daughter comes in and says maybe they are too tall and picks a wrench to print.


I'm getting frustrated now...

I do another 10 print attempts tweaking every option or so and no luck nothing.  This stinks.

I come back in the evening and try to print and nothing comes out the nozzle. Crap!  I run a fine guitar string through it and it goes through but nothing prints.  I try a bigger guitar string and it won't go through.  I try the small one again and it bends about 2cm in.

Ok what do I have to lose.  I look up some videos on cleaning extruder jams.  I take the fan clips off, loosen the set screw and pull the Bowden Tube? up.  Heat up the nozzle push some filament into the Hot End?  and nothing.  It is jammed up tight.  I get a 7mm wrench and small crescent wrench and unscrew the nozzle.  I use dental picks and wires and everything I have on hand to get the jam out and no luck.  I loosen the other set screw in the head and pull out the plastic tube in the heat sync and it is burnt on the end.  This isn't good.  The plastic tube melted into the nozzle tip.

Off to Lowes.  I buy a little blowtorch and acetone and come home and heat the nozzle til it catches fire and all the gunk burns out.  I run the guitar string through until I can see light through the hole.  Put it back together (booger up the insulating yellow pad).  Heat up the extruder and push some filament through and it is flowing good again.

I need a break.

I give up for the day.

History - Day 4

OK, This is obviously not working well.  I read some more last night and evidently ABS is hard to print.  So I open a box of white PLA. I go to Thingiverse and pick something appropriate to try to print in PLA.  I scale it down to 25%.   After a few false starts and increasing brim sized I get a good little: Thats right a little Turd emoji.  It worked but looks like a pile of strings.  The resolution is obviously off. So I try again and make it a little bigger. Much better.  Still a little coarse and not smooth.  But I get a marker and give it eyes and lips and hand it to my 11 year old as she heads out for her first day of school. I go back to the Pagolin and pick the other feet and print them after a couple tries: Not very smooth but at least the worked.  I try to print a Tinkerbell next at 25% and it makes it to her head then breaks lose from the bed.  I try different brim sizes and start playing with the temperatures...

Emboldened by a good cat print,  I installed Cura from the micro SD card.  On a Windows 10 PC. Followed the instructions on the PDF on the micro SD card and added my custom printer.  Went to Thingiverse and downloaded the Pagolin and loaded the front and hind feet and generated the .gcode, copied it to the micro SD, moved the SD to the back of printer and clicked print, selected the .gcode file and it promptly moved the head down tapped the 3 corners to auto-level then drove the head off the bed and into the "Do Not Touch" label where it got hung and vibrated very loudly until I could navigate to the cancel button and select it.  Then I selected to home it. Double check settings and try again. Same thing... Triple check setting and try again. Same thing... So I decide something must be screwed up. I install the Repetier software on the SD card.  I don't remember exactly what happened with it but after setting up it also missed the bed. So I try dow...
