Has anyone printed Benchy successfully? Stops extruding near the end. Overheating motor?

After many attempts to solve this on my own I'm going to have to ask for help. Has anyone had success with Benchy? I've tired slic3r and Cura, 2 different PLAs, loosening and tightening the tensions screws on the extruder, printing, lower and higher temperatures, printing at 90% flow and 110% flow. Stealth mode and 70% speed. PLA refuses to extrude after a while, most around the same stage. I've heard people worry about the heat of the extruder on the gears but I've yet to see a definite answer as to how to fix that. Any advice? I've been trying test prints for a month now and have yet to have one good, complete print. It also looks like Im getting slipping on the y-axis? (check the nuts, are snug)

Any suggestions?

This is my second 3d printer, I used to have a printrBot play.

Just a few comments :

First, your hotend is not "watertight". Try to screw your nozzle a little bit faster : https://e3d-online.dozuki.com/Guide/Changing+Nozzles/45
This results in this black carbonized balls arount your print.

Second, try printing your benchy with the bow in front. You have some cooling issues at the bow. Print with more fan speed for overhangs.

There is maybe an additional cooling issue with the chimney and flagstaff of the benchy. Print slower at short time layers.

All this settings can be adjusted at your slicer. Thry to fix this isses first. After then we will finetune your setting, if necessary.

Have you tried printing the benchy on your SD card that came with the printer? What was the result there?

Don't use .gcode on the SD card. It can be obsolete. Just resliced in the latest Slic3r and the result will be the best:

I believe that is Fillamentum Vertigo Grey. Wonderful PLA- I have both this and their Vertigo Galaxy as well- same praises.

Yep, the middle image is 3DBenchy Fillamentum Vertigo Grey Premium PLA: https://fillamentum.com/collections/pla-premium-filament/products/pla-extrafill-vertigo-grey

The silver one is Plasty Mladeč PLA: https://www.filament-pm.com/filament-1-75-pla-silver-1-kg/p78

And the green one is from some Polish cheap PETG: http://sklep.devildesign.pl/glowna/124-pet-g-175-jasnozielony-1kg.html

Ok, cause, I thought it was Galaxy Black.

Prusament Galaxy Black.

Bit of Trivia about "Galaxy Black".

You already are in possession of a sample of it.

Look at your MK3 Frame. That's Galaxy Black. 🙂

Thanks for the advice Thomas. So I've done the things you have suggested - Tighter hot-end, rotated the model, slower prints. Still no luck. After a certain amount of time the filament starts grinding and I have to stop. I''ve also tried the frog model and it dies around the same height as benchy is - And these layers are notably thicker than the benchy smoke stack.

Again I'm noting the ext ruder motor is too hot to touch right now. Im thinking of running the print in stages to see if that fixes it. I still strongly feel the heat of the motor is getting to the gear but I seem to be the only one experiencing this problem...?

There seem to be several reasons for hot extruder motor. Some of them found that their Extruder idler screws were too tight. Not sure if you checked that out.

Ya, checked those. Mine are not tight at all, couple twists past contact so the grip isn't too hard

Don't use .gcode on the SD card. It can be obsolete. Just resliced in the latest Slic3r and the result will be the best:

What do you mean don't use .gcode with the SD card? What to you save them as if not gcode? Sorry for the newbe question, but this is all I've heard people use.

He ment to not use the gcode files that came with your printer, especially if you updated the firmware since you received it. Download the stl files and use the latest version of your favorite slicer to generate new .gcode files

Sorry I'm new to 3D printing. So far I've been using the latest version of PRUSA Slic3er and the newest Fireware for the MK3. So I should NOT use either? What is the next best option?

David, you are good.

The gcode on the SD card may be obsolete - quality wise.
