OK - So I changed the nozzle and made sure it was seated correctly - now everything's back to normal :-)

It would be good to know how to clean out the other nozzle that's depositing black gunk!

Anyway, thanks again for your help.

**I finally fixed the erratic temperature and print head errors!!**

In my last post I said I changed the head - and this worked for the first 5-6 prints.

BUT, erratic readings started all over again and the printer kept pausing with nozzle errors every 5 minutes.

However, after looking at the head connector, I realised that the two contacts had large lumps of solder on either side ... thinking that these 'lumps' would push the contacts and cause a bad connection, I carefully removed the lumps of solder with a soldering iron.

I then reinserted the head and ... haven't had a problem since :-)

Thanks for your sharing!Cool!

Hi E180 lovers
after 3 months of work with no problem (changed nozzle once) suddenly no more heat at the nozzle. extruder 1 is seen OFF by easyrint.
everything looks ok no error message. readed the firmware, did everything i could with no success
stil wait Geeetech Technical advice on this
Any idea , did somebody got the same trouble already ? Thanks

in fact these are the status i see on easyprint screen
both the nozzlend the bed are declared OFF.

did anyone ever got help on this problem with 0 Temp on the Nozzle?

I have tried 6 nozzles, all the same problems. I took the complete head apart and resoldered every wire, every connection on it, traced all the wires down to the main board to make shure, no brocken cable. Put it back together, worked for 3 Minutes and all starts over. Eratic temp. readings up and downs. After letting it cooling down, no reading anymore at all. Tried all different nozzles, brand new once. I even checked the nozzles on another printer - work all fine their.

Geeetech technicians - what is the solution? Can someone please help

'Thank you

how did you solve the problem

Having the same, took the complete head in part, resoldered every wire and connection - still the same

Admin - any help ? any advice?

Hi，you can try

1. Check if the wiring is correct;
                       
2. Unplug the extruder and see how the temperature is displayed.
                     
3. Check if the thermistor is fully connected.

Someone tried to solder wires directly to extruder?
