Solved Failres on print bed and extruder. Please help me.

Greetings. Let the printer working on an 10 hour piece on ABS, checked for the first layer and seemed pretty well, leaved the office and the next morning I realized that the print job was unfinished, only did half of the firist layer. I tried to do another printjob but now on PLA and the results were the same. After all of this the print bed doesnt heat anymore.

Appreciate your help.

 

Thanks. Guess I forgot some details; the process seems wont stop, keeps doing all the movements but the filament stops flowing, I end up pressing Cancel. The second try was via USB and did the same. The printer is ROBO 3D Plus.

 

Just checked and the screws were ok, and cleaned the hobbled bolt.

 

Sounds like you might have a clog. Can you manually press filament into the hotend carefully while it is at temperature?

 

I concur with Danzca - my bet is a clog. Heat up to 250 or so and try and use some cleaning filament to push it out. That's the easiest method. If that doesn't work, you'll have to heat and remove nozzle to unclog.

 

Yes I can. Now Im doing a print job test to see if the problem was on the hobbled bolts.

 

Yes, extruded several times.

 

Yes it was. There were rests of filament between the hobbled bolts teeth.

 

Bad news I accidentally tear off one of these wires. Is there a way to fix it? Thanks.

 

Nope...that will need a new thermistor.

 

OMG. Do you know how much it costs? $$$

 

I already sent out my last spare or else I would just mail you one. Good news is a full hotend is only $39 from Robo...so no more than that. http://store.robo3d.com/collections/parts/products/hexagon-hotend-full?variant=9064408771

Let me see if I can find you something on Amazon for cheap. Just need a 100K thermistor.

 

@mark tomlinson do you know where you can get the cartridge style for the hex? All I see are the non cartridge style.

Thank you so much for your help. Thought it would be more expensive. That money will be taken from my check...

 

Get the rest of it out. I am curious if the hole is threaded. If so, you could always use one of these to replace it. https://printedsolid.com/collections/accessories-and-upgrades/products/screw-on-m3-stud-thermistor I've only used on an E3D hotend and can't remember if the hex has threads or not.

Still trying to find a cartridge style for you. I am search poor today I guess.
