Re: Fan not spinning

Thanks again for the quick feedback. I was in the middle of a 4 hour print when I noticed. I didn't want to cancel the print to debug :( The fan worked correctly when manually entering the M106 command. After running a few more diagnostic prints it seems that the extruder fan runs when when printing...

Fan not spinning

Sorry, another newbie question. I have noticed on my last couple of prints with pla (temp set to 205) the fan that is directed at the extruded material is not spinning. The fan on the heat sink seem to be working correctly. Over the last couple of weeks it seemed to be working. However, when I upgra...

Re: Mini Bed Level Adjustment

Thanks, I hadn't found the knob to adjust wiping temp yet. I'll try turning it down until the fiber stops sticking to the nozzle. In the mean time I use a non-metallic tweezers. The family is starting to think that the fumes are affecting my brain. A week with my new printer and all i have to show f...

Re: Removing scratches from pei bed

Thanks for the quick response and taking the time to answer a newbie question for the 100th time.

Searching for 'recondition pei bed' yield many results I missed in my first search.

Removing scratches from pei bed

Another newbie question.... When I received my refurbished lulzbot mini there were a couple of scratches on the pei bed. It looks like someone got too aggressive removing a well adhered part with the spudger. These scratches leave noticeable marks in parts. After reviewing the various forums and mai...

Re: Mini Bed Level Adjustment

My working "newbie" hypothesis is that the hot end must be perfectly clean of plastic and any fiber that comes off the nozzle cleaning pad before performing the auto leveling procedure. Any schmutz, even a single fiber, from the nozzle cleaning pad can prevent the nozzle from make good electrical co...

Re: Skirt doesn't start printing until most of the way round

I have found this to happen to me as well. An interesting experiment is to draw a mark around the filament where it enters the extrude head. Then watch as the filament retracts and feeds during the nozzle clean and the start of the print. Most of the time the filament does not feed back into the ext...

Re: Mini Bed Level Adjustment

I would like to confirm that I am getting a similar error with the automatic bed leveling on my refurbished lulzbot mini. 1. The issue is random. Sometime the problem occurs and sometimes it does not. I am brand new to 3d printing so I am still learning the cause and effects involved. 2. Some times ...
