So the Mini 1 and Mini 2 have the same bed leveling system. Neither is adjustable by the user, both use the 4 points offset at the corners. The Lulzbot mini is a solid printer as is the Ultimaker, I think it is more of a question of, if you are going to be running anything other than PLA and PETG, is it easier to replace a nozzle or a tool head? The Ultimaker is going to be more cost effective in the long run because of the ability to replace just the nozzle with hardened ones or other sizes whereas the Lulzbot may require replacement of the tool head depending on a number of factors.
Hi...in my case the adjustment screw for tension is overly difficult to adjust, and from the factory set very tightly. On the flip side you can sortve see where the filament is going if youre having trouble loading it. It doesnt seem to feed 1.75mm as well as the original extruder does, after a couple attempts just to see (since I had files sliced already) i gave up and sliced again. The fan mount is a bit better placed so you can still see the nozzle and get to it to clean it easier. I was disappointed that for the price it did not come with a silicone sock already on it.
I am sorry for us getting to this one so late but hopefully the information I am providing will be useful to others in the future! So this kind of issue is most of the time caused by the previously loaded material is not heating up to temp fully causing a slight blockage and excess pressure in the hotend results. In turn this will cause the feed system to grind up the material. To resolve this we would normally recommend to purge the ABS out with a cold pull which you can find the instructions for here.
Give these a shot if you still run into issues or feel free to reach out to us.
@ajusay74 There could be several reasons for this issue. If it occurs at the same layer height for different types of filament, then it is most likely a firmware issue. Feel free to contact us directly if you need to do more of a deep dive on this issue.
Thanks for the reply. I took a chance a just copied the wipe code into MatterControl, replacing the relevant section. Seems to work just fine. I'd be more comfortable if the bed didn't shoot so far forward, as the first tip *just* touches the wipe pad, but I'll worry about tweaking that later.The Y axis for the 2nd extruder was "-50" (*minus* being the key), and seems to be working fine after a couple of test prints. It's weird thinking about how the numbers will be interpreted, but fortunately everyone seems to follow the same co-ordinates, so the dual extruder calibration steps for the TAZ 6 seemed to work just fine in MatterControl. I did see the Printer Profile Bounty. Not sure that I would have any *significant* tweaking to qualify, but I'll keep it in mind.As an aside, love the "Preheat" buttons!Thanks,Dion
