Or print from my tablet with the G-code printr app, which I do most of the time.

I too have a relatively old and weak laptop and even slicing fairly large or complex objects freezes the printer. I've just lived with it this whole time.

Try getting a fan pointed directly at the controller board /stepper drivers to cool them better - the little 40mm one that SD uses on the bottom isnt enough.

I managed to point a small fan towards the board and it seems to do the trick. I might have to flesh out a more permanent solution to the problem though. Thanks for the tip mate!

lol, yeah, i am running ours from an old XP machine & dont do anything else with it while printing or it starts having issues. LCD & SD card reader are on the upgrade list...

Hi guys! I purchased a Solidoodle 4 last year and it's been working great the whole time.

Just recently, I've been printing pulley sleeves and it's been randomly stopping during prints. There is still plastic oozing out of the nozzle when it stops, but the extruder itself doesn't move, leaving a very small but inconvenient blob on the surface. Not even a second later, it resumes printing.

What would be the main cause of this as it has never happened before? I suspect it might be software issue and not a hardware issue.

During the print, I was printing black ABS on hairspray/kapton tape (210 deg C @ nozzle; 110 deg C @ heatbed)
