This is wonderful. Spent the whole day reading learnt so much on 3D printing. Count me in... looking to get one for some fun and printing. Will continue to do my research and update if I actually take the plunge.

Just curious, what combination of G-Code generator, Host software and firmware are you guys using? Any recommendation on which combination is best for a beginner?

Thanks for the feedback.. looks like many things to read up on.

Hi All,

Firstly Happy Chinese New Year to all....

Been printing many calibration cubes over the last couple of weekends and when perfectly. Got a bit ambitious over the last weekend and started printing some larger prints.

All is well until about 1.5 hours into the print, the extruder got jammed. Still patient, I clean up the hotend, and started printing again. This time it lasted a bit longer, a bit less than 2 hours. Unfortunately, it jammed again at 90% of the print. Clean and tried again, with same problem.

Anyone have any idea why it only jam up after printing for more than 1.5 hours? Print quality before jam looks good....

I am printing with PLA, at ard 185C, heated bed at 60C. Using a J-Head with fan. Symptoms starts with the extruded PLA becomes thinner, then starts to comes out in droplets every few mm, then the droplets get further apart then it just jams.

I am clueless now.. Any suggestion on what to tweak or change...

Thanks KLKS and altan for the feedback, this is great community here..

I will check on the filament tomorrow, sounds like a plausible explanation. I cannot think of any other reason for this to happen randomly given the same condition of printing.


Thanks for the tip.. will do a full cleaning this weekend before attempting to print. However, any options other than blow torch? My blow torch just happen to masuk repair shop .. Will a simple cigarette lighter work?
