Re: Mini Z motor grinding noise and binding

One more thought on this topic, in case anyone else has the problem and reads this thread. When my Mini arrived from the factory, it had all sorts of problems. Digging in, I discovered that the two Z drive systems (on either side of the printhead carriage) were grossly out of synchronization. If the...

Re: Minimum feature width?

For the Layer view that I mentioned that should be available in your version, it is available in Cura 21.08 which is from the same branch of Cura and had the same basic layout. In legacy Cura this is in the upper right of the screen in a box like the load model and control boxes, it should say norm...

Re: Minimum feature width?

One thing that may help with this would be the Print Thin Walls option in Cura... I've just checked again, and I can't find this option in the Basic, Advanced, nor Expert settings in Cura. I'm using version 21.04, so perhaps this option didn't appear until later versions. I realize 21.04 is an olde...

Minimum feature width?

I'm modeling what will eventually be a small injection molded component. It has two vertical walls that start straight for a centimeter or so and then curve about 90 degrees. The walls are 2.5mm tall and 0.5mm thick, and since my Mini has a 0.5mm nozzle it's right at the limit of resolution. I knew ...

Re: Version 1 Mini Extrusion Issue

When you give it the command to extrude 10mm (or some multiple thereof) and it doesn't extrude very much, release the clamp and pull out the filament. Do you have clear marks on the filament where the "hobbed wheel" (the knurled part that drives the filament) has deformed the filament? If that wheel...

Re: Lulzbot Mini requires huge maintenance

Please post a video that shows the start up routine and beginning of the first layer of a problematic print. You can type descriptions of the problems endlessly and may never convey what we need to know to help determine what the problem actually is. I'll do that. Also, if you have not tried a diff...

Re: Lulzbot Mini requires huge maintenance

In my experience, excessive oozing is due to the nozzle temperature being too high. Try lowering it a few degrees at a time to see if that helps. Yep, that was my theory too. I've lowered the temp a bit a time until it no longer adheres to the bed and interlayer adhesion is failing... it still drib...

Re: Brand new Micro Swiss nozzle, still curling coming out of the tip

Update: This Mini is mostly working now. It appears the factory nozzle had "issues" and replacing it with decent quality aftermarket nozzle resolved those. Still fighting the dribbling problem at startup, though. I have to carefully watch the nozzle during final warmup and use tweezers to grab the d...

Re: Lulzbot Mini requires huge maintenance

Update: Since repairing the right side switch stop as described above, and replacing the factory nozzle, the Mini is working - sort of. The dribbling problem at the start of each print is still a HUGE problem for this Lulzbot device, but once I get past that (manually) the prints themselves are fine...

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...
