Thanks for the suggestions! I'll start by increasing the current to 1200mA and if it doesn't help, I'll take apart the hot end. When you took the hot end apart, did you find the reason why it might be more difficult for the motor to push the PLA through if the material has been left in the hot end overnight?by tml - Fisher
I have a RepRapPro Fisher from around November 2015. It works fine but I have a very strange anomaly I can't really wrap my head around, and it's the skipping of the extruder drive. The printer is completely stock, so the drive is a geared one, driven by a Nema17 and the Duet electronics. The nature of the skipping is weird. It usually starts mid-print, after 15-20 minutes of printing. There aby tml - Fisher
Fisher (and duet): I checked the motor currents. Quote M906 Axis currents (mA) - X:800, Y:800, Z:800, E:1000:1000:1000:1000:1000, idle factor 30 I already figured out the idle factor empirically when checking the strength of the idle hold. I noticed that the strength required to rotate the small gear is moderate in the first 30 seconds and much easier afterwards. Almost as easy as when the moby tml - Fisher
Hello, I have a RepRapPro Fisher 1.0. I've been using it for almost a month now and noticed that in case of some filaments it needed a much higher temperature than my other 3D printer (a Huxley). It seemed to be getting worse and worse every week. I finally concluded that there was something wrong with my extruder drive. The symptom is that during a print, sometimes the extruder drive keeps "by tml - Fisher
TLDR; I have recently discovered the absolutely superb "Lift Z on retraction" feature of Slic3r. I'd like a way to configure this to happen on the first n layers only. Long version: The problem I solved with this feature was that the molten PLA was oozing a bit which caused serious problems on the first layer if the object being printed had tiny or really thin parts (like a 2mm sized thing orby tml - Slic3r
Dear John, I just had a similar issue with my emaker Huxley. Fortunately I noticed the wrong temperature reading before turning the thing on so I did not melt my hot end and broke the glass. After a careful comparison of my ATMEGA644P to another one I noticed some weird resistances on some pins, so I replaced it, just to break the new IC too. So, basically, if you do not insulate the wires arby tml - Reprappers
