heat resistor dead at 3 months

Just wanted to record this for those who may encounter this problem. I had been printing for about 3 months with a batch one taz when the extruder stopped heating yet the thermistor read correctly. The likely source of the problem was diagnosed with a helpful Claudio from Lulzbot support over the ph...

Re: Even Bed Heating - Possible?

I know Lulzbot is working on a new heated bed (which I'll definitely buy as an upgrade when it's available), but the current bed has relatively uneven heating across the surface. Has anyone found any way to mitigate this when you have very large prints? Is it true Lulzbot is going to offer an impro...

Re: PLA extruding

Hi Adam,

check out this topic: http://forum.lulzbot.com/viewtopic.php?f=36&t=202

my design is posted there as well as other potential solutions

since installing my dual fans the jams have completely stopped and I have yet to find a limit to print times, longest yet was close to 40 hours!

Re: Taz fan mount?

I also printed the recommended fan mount and had the same questions, which fell on deaf ears

so I designed my own, file attached, hope it helps

Re: Switching to PLA from ABS

my best results with getting PLA to stick are on bare glass, cleaned with denatured alcohol, heated to 65c, first layer at 200c with moderate squish. as an aside, I've found that cleaning the glass with alcohol too often degrades the adhesion for what ever reason. so I clean only when needed. I trie...

Re: Budaschnozzle 2.0 PLA Fix

Sure, the fan mount I designed is attached, notes: -The 45 degree orientation of the heat sink fan (top) is not ideal; some air blows onto the heater block. -The print fan (bottom) could probably benefit from a duct, the hot end gradually loses heat and can't maintain temp. -The chicken and egg iron...

Re: PLA extruding

Hi Chris, Success! I installed the two fans and have completed prints of 7 and 18 hours. For these prints only the fan aimed at the heat sink was turned on, no jamming. Any print over 2 hours was unthinkable a couple weeks ago, pretty excited. My theory, becoming supported with increasing experience...

Re: extruder jams on larger prints and other problems

Just wanted to bring resolution to this topic: -filament jamming on 2+ hour prints was solved by mounting a fan directed at the heat sink. Prints of 7 and 18 hours have been completed without jamming. While a second fan was mounted and aimed at prints, this was kept off during my tests. the heat sin...

Re: Budaschnozzle 2.0 PLA Fix

Agreed, the hot end should not be allowing heat creep, but it does. Yes, in fact I installed two fans; one always on directed at the heat sink, and another directed at the print controlled by slicer. With this setup I completed a seven hour print without jamming. Without the fans the extruder would ...

Re: motor noise and layer fail in same position

In repetier host, you can simply drag the model file to where you want it with your mouse. You can also rotate it any degree you want, on any axis. if you are using pronterface, I am not sure if you can do that.....I suggest trying repetier host out. it is MUCH more user friendly and integrates sea...
