Two binaries work together to compose the magnum system. The first binary(accessed by the python-magnumclient code) is the magnum-api REST server. TheREST server may run as one process or multiple processes. When a REST requestis sent to the client API, the request is sent via AMQP to themagnum-conductor process. The REST server is horizontally scalable. At thistime, the conductor is limited to one process, but we intend to add horizontalscalability to the conductor as well.

So I've been using the MK3S (and its predecessors) for years, have four of them running nearly around the clock (all stock). But I recently picked one up locally secondhand. The unit is in great shape, barely any printing time on it. But a new thing for me is the mods that are installed on this MK3S. They include:

All of it seems assembled very well, boron nitride paste in all the right places (and he gave me the extra). Right now, as is, it really is printing quite well, and I am happy with the quality. So this is not a 'how do I fix it' question. But rather, how do make use of the high flow Mosquito Magnum? I have read all through my searches here (including a 20-page topic), all through Reddit, even contacted Slice. I would like to see what the potential is here to print with larger nozzles, higher speeds, and use this machine for all the prints that are bigger/bulkier. Slice said just to increase the speeds. So I went to print settings/speed, and started cranking up the speeds, but my print time did not seem to improve much at all; maybe a 4 minute decrease of a 3 hour print. I've ordered a 0.6 and 0.8 nozzle, but switching that setting doesn't seem to bring print time down too much either. In my searches, I've also come across a magnum profile from Chris Warkocki for PLA with a .8 nozzle, and plan to try that out when the nozzle gets here.

So what do you think, what settings do I tweak to get the most out of this guy, and what are some good profiles that I could use as a starting point? For reference, 90%+ of my prints are PETG, so that is what I am using in most of my tests. Really appreciate the feedback!

When switching nozzle types and sizes or working with a new hotend, I like to do some quick maximum volumetric rate testing. I've got notes on the process I use here. This is sufficient to identify a maximum to be used, not necessarily one that will give an optimal finish.

As I've just got one of these to change from the E3D V6 hotend, I will watch with interest. I am having difficulty with PETG with a very fine detail print (0.2 nozzle) both with the original V6 and the Mosquito Magnum hotends, so @dustinjay and @bobstro info and site are welcome. Some of the lines are about 0.4mm wide on the plate and will print using PLA, but PETG just won't play. I'm convinced it is something to do with the flow rate as I get a build up around the nozzle which then drops and messes up the already printed bits on the plate.

I can't say for Bondtech Mosquito Magnum hotend, but for Bondtech standard E3D V6 hotend, there are more changes in custom firmware (not only for E-steps). And I'm quite sure that's the case for Mosquito too.
Here are changes that I've found for Bondtech E3D V6 extruder:

Unfortunately, no, or at least not the kind of updates that are helpful. I have quite a few other MK3S printers running, and for me, I only tinker with the machines when necessary. So the bad news: I reverted it back to stock. Stock just runs like a champ, and I don't have to worry about a different firmware.

Thanks for the input but perhaps I should have mentioned that I am using the Prusa supplied Mk3S+ extruder stepper and Bondtech gears in conjunction with a printed PETG 'body' from Thingiverse. I am not using a complete Bondtech extruder mechanism. Thus I do not have to use a different firmware. I have tried the Prusa Slicer defaults for Ultradetail 0.05, Extrudr and Generic PETG filament and Mk3S+ 0.25 nozzle. I have tinkered with these settings (e.g. reducing the nozzle size to 0.2) but I can't quite get it right! I have adjusted the Z level a bit higher than for PLA as suggested by others. I guess I will just have to either a) keep tinkering with settings, or b) give up and join a monastary! ?

The impressive magnum bottle of The Altruist comes tissue-wrapped in a lovely gift box adorned with the Markham logo. Accompanying the bottle is a note from Winemaker Kimberlee Nicholls with a certificate for a complimentary Markham tasting experience.
