The filament is sort of a hybrid between PLA and TPU, it's stiff and yet flexible. It printed nicely without problem after up the temperature from 185C to 210C.

TPU Filament Drive Jammed

I'm experimenting with this TPU filament https://goo.gl/iDUQVi, it's more like flexible PLA than true TPU. It prints very nicely, however filament drive would jammed randomly out of nowhere, see photo. Any idea how it would jammed like this? 20180212_164827.jpg Here is my Slicer settings. Thanks sni...

Re: Dial Indicator Quick Mount

I see what you're saying. With all those bolts locking the rail on to X axis frame, plus M2 is built like a tank. So the X axis frame should be parallel to the actual rail. I just finished a large print job 11x19x9 cm that took 17 hours and bed level works fine. Your millage may varies. :D

Re: 1st Gen M2 12V Fans Run on 19V?

I print mostly in ABS and don't really print all that much. Both E3D and V4 options require more mod time than I have right now. For the time being, I'll take on Ed's offer and will look into upgrade to 24V setup later. Thanks for all the inputs.

Re: 1st Gen M2 12V Fans Run on 19V?

If the wire going to the MOSFET is shorted to ground, then the heater will start heating up. However, because the MOSFET / thermistor / RAMBo aren't in control, the heater will continue geting hotter until it burns out. So, by and large, Something Bad happened to the extruder heater wiring. You mus...

Re: 1st Gen M2 12V Fans Run on 19V?

I think 1st gen M2 was meant to abuse the 12V fans with 19V power. The fans are much quieter (pushing a lot less air) after I installed buck converts, but after two minutes the extruder started to extruding even though it's not set to heat up and followed by magic smoke. The smoke was from the melti...

Re: 1st Gen M2 12V Fans Run on 19V?

Thank you. I'll pick up a buck converter. I guess the fans have always been running on 19V since day one...

1st Gen M2 12V Fans Run on 19V?

So all the fans on my 1st gen M2 are running on 19V and they are rated at 12V, wouldn't that shorten the lifespan of the 12V fans? Can voltage be step down in the firmware?
