So remember how I said last week I thought I had fixed my jamming issue? Well I was wrong.
I'm not sure if it's the material, which it shouldn't be as it's the same brand I always use or if the nozzle is buggered, which seems more likely as it's the same nozzle that came with the machine last September.
In any case, the only way to sort this out was to change the variables one at a time until it fixed itself and to do that I did following over the past couple of days;
Change the material and try and print with the same nozzle and settings.
This didn't work, not much more to say about it.
Change the nozzle and print with the same material and settings.
So I ordered a load of new nozzles to see if it was the nozzle, and again this hasn't fixed the issue, which leads me on to the last thing I can think of.
After a bit of research and asking around on the Cetus3D users fb page, it looks as though there could be a problem with the heating element losing power during a print. This would cause the temperature of the nozzle to drop to the point where the filament cannot be pushed through and the print fails.
This scenario had occurred to me but I was REALLY hoping it would just be a duff nozzle, however it looks as though it may be a little more serious.
Next steps for this will be for me to replace the PCB in the printer (I have a spare that Cetus sent me after I had some extruder motor issues) and if that doesn't work I may have to learn a bit of electronics or see if I can get Cetus to send me a replacement extruder head.
Wish me luck guys and I'll see you next week with an update.

I did a cold pull
This involves extruding filament through the nozzle until it is full, then letting it cool to just above the glass temp of the plastic, in this case around 100, and then manually pulling the filament out. If done correctly it should come out with a little pop in the exact shape of the inside of the nozzle, pulling any debris with it.

I thought this worked, however it appears I was wrong yet again.

| First print worked yay! |

| False alarm, back to crappy failure on the second... |
