Re: Y-axis 0 endstop question

Now that I've had a day to think about it, I realize my theory of the 1.0.4 part fixing some Y scale problem can't be the right explanation. So I have no idea why replacing the 1.0.3 Y motor mount with the 1.0.4 part fixes the nozzle wiping position problem. I'll just have to be content that it work...

Re: Y-axis off, cleaning hits pad holder

I see I left off some important details about replacing the 1.0.3 Y motor mount: Follow the 1.0.4 instructions about setting the horizontal screws in the mount so their heads are just flush with the face of the part. If you tighten them much beyond that, the nozzle won't wipe in the correct place. T...

Re: Y-axis 0 endstop question

By the way, my notes collecting all the info you need to print and assemble the 1.0.4 Y axis motor mount is on another thread here: https://forum.lulzbot.com/viewtopic.php?f=43&t=7762&p=42822#p42737 . That post gives the McMaster-Carr urls for the parts, based on the Lulzbot Mini Bill Of Materials, ...

Re: Y-axis off, cleaning hits pad holder

Update: My Lulzbot Mini now successfully wipes the nozzle in the right place! Yes, replacing the 1.0.3 Y axis motor mount plastic part with the 1.0.4 part and (importantly) installing that part according to the 1.0.4 instructions, fixed the problem for me! See my lengthy note on why, at https://foru...

Re: Tips on prints that fit together

Update: see my notes on how, on the Lulzbot Mini, the nozzle missing the wiping area can be caused by Y scale problems: https://forum.lulzbot.com/viewtopic.php?f=43&t=5793&p=42819#p42819 In short, since version 1.0.4 of the Mini, the nozzle wiping is a Y dimensional accuracy test. If your nozzle hit...

Re: Dimensional accuracy

Yet another update on my dimensional errors issues and fixes: A seemingly-unrelated problem with my Lulzbot Mini was that ever since it came back from Factory Repair, the nozzle had been missing the wiping area. It turns out, that's a symptom of a Y axis dimensional error. I replaced the 1.0.3 Y axi...

Re: Y-axis 0 endstop question

I, too, agree with ScottW's suggestion: my Lulzbot Mini 1.0.3 had the same problem (wiping too far back), and replacing the 1.0.3 Y motor mount with the 1.0.4 part fixed the problem! Interestingly, simply replacing the part didn't, at first, solve the problem. The 1.0.4 Y motor mount has two pair of...

Re: Recommended additional equipment?

Wow! Thanks for the tip, Zachah. I had no idea that the Nozzle is an ESD path to the controller. (Naively, it sounds like a job for 2 diodes, but I understand how hard ESD protection can be.) Thanks again for the warning; you've likely saved me from accidentally blowing up my Mini. I'll now treat th...

Re: Recommended additional equipment?

Bins and desiccant for keeping your filament dry. Several types of filament can absorb moisture from the air, which can cause irregular extrusion. RepRage has a good post on the effect, at https://reprage.com/post/3D-Printer-PLA-moisture-problems-and-storage-solutions . I bought a set of Ziploc Weat...

Re: Recommended additional equipment?

A few months ago I bought a Raspberry Pi 3, loaded OctoPi/OctoPrint on it, connected it to the house's wifi, plugged the Lulzbot Mini into it, plugged in a Logitech usb camera, and voila! I now send gcode files to the printer instead of walking an SD card around the house, and can watch the print pr...
