A hot end may smoke after servicing/ cleaning when using any cleaning fluid, grease, sweat from fingers or excess residue. I do not think that it is any cause for concern. Continue to feed filament out of the hot end and if the problem persists, open up a support ticket.
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.
It comes down to production scale and target markets. The MAKEiT Pro printers are made in small quantities relative to other manufacturers so there just aren't as many printers in the wild, and their target market are primarily universities and institutions.
Just to give you an example, JPL (Jet Propulsion Laboratory) and Cal-Tech were one of their first customers and to our knowledge still maintain a working relationship. If one were to speculate, you might surmise that due to the relatively small quantity of these printers on the market, it wouldn't quite make sense for a major publication like MAKE to commission a write up on these printers for their annual review since their business is to help move printers into consumers' hands during the busy season and the printers are made in small quantities. JPL/Cal-Tech probably aren't interested in offering feedback about the printer and its use cases for online forums; they're busy making history. Just speculation, but it would make sense if true.
In any case, I hope that answers your question. If you have other questions or insight please feel free.
This lets you mount a DyzeXtruder GT in place of the EZStruder. The DyzeXtruder is nice because it has a locking release lever, so you don't have to hold the lever while you insert or remove filament. It also has dual pinch wheels (like the Bondtech) and is fully constrained for printing flexibles. Print two of these. One goes on top, one goes on bottom.
They appear to be a chemical compounding company that is using their resin as the technology. The machine is super simple. That said - simple is very easily scalable. They are using visible light (460 nm wavelength) to cure the resin and the lightsource is any LCD screen. The genius of this is that the screen - and therefore the technology platform - is very scalable and cheap. Nothing stopping you from having a simple Z axis and mounting a 52 in TV as the light source.
Unproven as of yet - but could be interesting to keep an eye on. A liter of the resin is priced at about $65 per liter.
