Maybe turn off retraction? The print may turn out a bit more messy, though, with extra wirey bits to clean up.

I just read that 3dninja.nl has been declared broke. The curator is Eric Poelenije. The website is still online but I advise to not order anything there anymore. Gr., Alex

Let me put it this way: On the Ulticontroller I see the actual temperature rise way above the target temperature.

Hmm. I ment those surgical-like SureTouch things, but i suppose they're also a bad idea. I built the thing in the attic, which is all wood and nothing to ground to. Managed to never touch the electronics though and no sparks were felt. Is this mosfet on the heater board underneath the bed or on the main board? I'll probably have to return only the defective part to the reseller as it is a DIY kit.

Hi there, newbie here. I have the same problem with my recently bought UMO+ . Didn't touch the electronics during the build (rubber gloves) , checked all connections twice, upgraded the firmware...
