Unresolved Clogged extruder

Greetings again. I got the thermistor that I broke, so thanks for your support. Now I have another problem, after I changed the thermistor, made a few prints with a pretty good quality, the printer was working well, but now the extruder cloggs after the first layer. . What seems to be the problem?

Thanks in advance.

 

Did you remove the nozzle to clean it?
I bought a 6 pack (or a 5 pack) of nozzles from amazon for a reasonable price. Cheap enough that if it takes more than 15 minutes to clean a clog it's cheaper to toss the old one and put a new nozzle on.

If you did take the nozzle off to clean it, you may possibly be pulling some grung into the extruder with the filament. I have dogs and cats and although there may be debate on the merits of the oiler, at the end it makes a wonderful lint, dust and pet hair filter.

I will not run any filament without an oiler. Funny thing, since installing my oiler, I have not had a single jam. Hmmmm. (now watch Karma come knocking)

 

Can you tell me:

1) How to determine what nozzle I have in my brand new Robo 3d R1+?

2) Where to get and how to install an oiler.

Please forgive my stupid questions. I've been 3d printing for about 2 weeks (and my nozzle is already jammed without having even printed the spool that came with my printer).

Thanks in advance.

 

You have an all metal hexagon hot end with a brass 0.4mm nozzle. Any nozzle compatible with an E3D V6 hotend also work with it.

Oilers are all over Thingiverse. I use this one since I use a spool holder that is top mounted.

Haha...@Geof your too quick tonight for me

 

Beat me to it but I'll agree, .4mm brass nozzle is what came with mine only about 8 months ago.

I bought some spares here:

Be sure to look for "M6" in the description. I almost bought "MK8" until I checked here and was set straight.

The new nozzles are great and have real multiple flats to work a wrench on instead of the stock nozzle which has only 2 flats.

Don't forget to bring the nozzle up to full temp before taking it off.
I didn't know that was required and I busted my wires and thermister but good my first jam. Which, by the way happened within the first day I started using it. So, don't feel alone.

As for the oiler, I printed this one:

I put two pieces of fine celled foam in each half so they squeeze around the filament. I put a few small drops on both pieces of foam and it clam shells closed. It has a slider to secure it. Mine printed a bit loose on the clasp but it was quickly fixed with a couple of squeezes with the plyers to slightly deform the rail it slides on. did without the bell thingy the author touts.
