Re: Lulzbot Mini requires huge maintenance

I dont see how that switch could have caused any of your issues. Thats the one on the right side of machine. The mini doesnt home to that side at all. The only purpose of that switch is to stop the toolhead from hitting right side of machine if code has it move outside its travel limit. I believe t...

Re: Wiper Pad Alternatives

Your thermistor wires are positions 15 and 16 To be accurate, on this Mini the thermistor wires are in positions 17 (red) and 18 (black). See Figure 6 here: https://ohai.lulzbot.com/project/86797b55-7d08-4c6d-be77-3c116a320547/mini/ My Fluke meter shows 145.5K with the nozzle at 19.7C. Quick linear...

Re: Wiper Pad Alternatives

Aside from trying to fine tune temperature control on your toolhead if you are seeing that drastic of a difference between your thermistor read out and the actual temperature I would suggest checking your thermistor itself to see if it might be damaged. It would have to be defective , as it's done ...

Re: Wiper Pad Alternatives

Something that might help would be completing a PID tuning on this toolhead. And: I understand what PID control loops are, and understand how tuning the PID parameters might help the nozzle temperature be held more consistent during a print job, but I don't think they will be more accurate . As lon...

I only use Cura. Are the GCode commands the same in Cura?

Re: Wiper Pad Alternatives

I have to wonder if you're not suffering from overtemp. I've tried reducing the temp to 200C. Right now I'm at 220C, and I've gone higher. No changes, same result regardless of temperature. All of the above numbers are what Cura displays. See below for more accurate temp info. So, I'm wondering if ...

Re: Wiper Pad Alternatives

It did this BEFORE the new nozzle too? Yes. I would contact Lulzbot support to see what to do. So far they've had me: 1) buy two new printhead fans 2) buy a larger printhead fan and convert the style used on my printhead to this new style 3) buy a brand new print bed, but fail to tell me that the n...

Re: Wiper Pad Alternatives

This IS a new nozzle. Brand new Micro Swiss 3mm/0.5mm nozzle. Literally installed it a couple of days ago, thinking it might be the cause. It's obviously not. Also, this dribbling issue is across multiple types and colors of filament. And temperatures. I've tried everything I can think of, including...

Re: Wiper Pad Alternatives

Use a skirt. It will prime the nozzle and the "glob" will be deposited on the skirt rather than your print. I do use a skirt. It's the default in the Lulzbot version of Cura. What happens is the glob of filament flows down to the print bed as the nozzle lowers to it in preparation for printing, the...

Re: Wiper Pad Alternatives

We are extremely careful about cleaning our nozzle before and after every print. This makes me wonder if I can edit the GCode to eliminate both the "cleaning" operation, and the 30mm retraction cycle it requires. This would save time and, more importantly, leave ME in charge of how much filament is ...
