Hello,

It's my first post on here so please be gentle!

I bought an Ultimaker 2 Go a couple of months ago and have so far produced approximately 30-40 small'ish prints. It's been pretty good and the definition and build is certainly better than the Cubify Cube that I had previously. Everything has been fine until yesterday when after a successful print, the next one just wouldn't work. It produced a scraggy first layer, very stringy / patchy, then continued OK for approx 1cm of build after which it stopped laying material down.

I've noticed that the feeder has started ticking back / skipping. I've removed the material and tried the unclogging the nozzle. It seems clear as the material I removed looks nice and conical, like the website says it should. No signs of dirt etc... The material has the right marks in it from the feeder suggesting that the tension is correct. I have tried unclogging the nozzle several times, always with the same result and I can see right through the head and nozzle. Once I feed material in again though, I get the same problem. The material seems nice and free on the spool too and when I 'move material' through without the tube attached to the head, there's no issue, suggesting resistance at the nozzle.

I have a spare head/nozzle but before replacing any parts, I'm wondering if there's anything else I could try? I don't feel that I've had enough use to justify replacing parts already but sometimes these things just happen I guess.

Any advice would be most welcome.

Many thanks,

Haydn
