What did you end up using for a hotend/extruder? I've got the same one as your stock photo and I'm attempting to reuse mine but can't find a mount

I'll check out the orbiter 2 then. I mostly print PLA but I plan to add an enclosure for ABS eventually. Right now I'm using my works X1C for my ABS prints. I'm undecided on a hotend still

Sherpa is able to easily push 36mm3/s
normally when your extruder struggels, its a sign of the hotend being limited
how much retract at what speeds?
are you running a 20mm or a 17mm stepper on the sherpa?
well, phaetus didnt rip off anything, standoff tubes are nothing new
also if you dont like ripoff companies, you also cant support slice since they ripped off the vz goliath
17.35mm/s is really slow :O
yeah
normal retraction speeds for a dd are something like 100mm/s, that's why I was confused
ah, you used the sherpa heavy, right?
I'm running 120mm/s with 0.75mm retraction on my sherpa mini without issues 🤔
I feel like there is something else at play here
maybe too high pa values?
pressure advance
I also love my rapido
cause there was nothing like it on the market when I bought it and its light and has a lot of flow, does that make me a bad person?
Not everything from china is a rip off
I mean I am not american, so maybe I dont get the nationalism behind slice, I am just really annoyed they sued a company for no reason and then had the audacity to rip off the goliath, after accusing others of ripping off their stuff (I dont blame anyone for buying their stuff since apparently it is really good, even though the prices are a little unreasonable imo)
0.2 should be totally fine
it depends on speed
but it will not kill the extruder at 0.2
I'm running 0.3 at 450mm/s with a printed sherpa mini so you should be totally fine
did it skip as in stepper skipped steps or skip as in grind?
maybe your hotend did partially clog and thus the issues occured?
ahhhh
tpu is problematic

I've looked at the mosquito but it's quite a bit more than the dragon and such
proven coyote
That should be fine
I am confused

i have just copper heatsinks and the difference was big. i may add fans but im going metal stepper tower which will help reduce temp also.
vital acorn
My setup wouldn't have much room for that unless the ducts weren't straight down.

What is that stepper cooling???? Dear god
wintry swallow
are you using the two piece rail carriage?
i had a rough time with dragon and archetype on the initial one piece carriage.
wintry swallow
i ended up moving away from the design because i thought it was going to be too difficult to cool the heatbreak with a rail directly behind it.
yep
the 2510 is not the problem, imo
proven coyote
back pressure could be a thing
that's something I noticed with the lightweight gantry:
There is a bunch of air coming out the back so that could actually be the reason
yeah I meant it in a positive way on the lw gantry
less back pressure
wintry swallow
when it comes to the dragon - which probably has one of the hardest heat breaks to cool out of the uhf group, i have a couple. the one in archetype is the only one that caused clogging and melting. i don't think its too close to the carriage - i think there's no clear path for hot air to travel, so it lingers which results in less cooling.
look at xol for example, you can see a clear shot from the 2510 to the back of the tool head with dragon
i also used xol with an nf crazy and had no clogging issues
wintry swallow
What brand of rails are those?

Any thought to building a custom frame for your Merc?
I have an idea for an Uber Merc frame using 4040 uprights, solid panels on all sides and a klicky klack door...
wintry swallow
here's a sherpa mini flat top that i modified to use heatsets
wintry swallow
from a design perspective, ive learned that the smaller parts usually do better with chamfers that are in increments of layer height.
wintry swallow
your part has filets in it
vital acorn
i get to do this today also lol. finally got my breakneck up and running.

hey @brazen stag remembering you mentioning double shear support, did you add it? I skimmed the log but couldn't see it
azure stone
I'm thinking of trying out something like this https://www.printables.com/model/299097-motor-decouple-damper
mostly because it allows to "extend" the shaft
these will go on my rat build
azure stone
true, I see it more as a way to add double shear with existing steppers with short shaft
people using those specific ones did not report issues, I'll experiment
vital acorn
you looking for a mount for can for archetype orbiter?
okay. i have one for orbiter with new filament sensor. lmk if you need it
would love to see what you cook up. i have been working on a cutter.

on a side note, my high temp CPAP tubing howls like a raped whale
night radish
It whistles great over certain print geometries
brazen stag
yes. This isn't actually CPAP tubing, I couldn't get that to last more than a few prints at my temps & speeds. the inner kept collapsing in all the stress points
night radish
This USA made stuff I got has held up through the hell Ive put it through
brazen stag
idk, I tried half a dozen brands and it all ended up the same way so I used the stuff Oof is trying on the high temp server.
CPAP tubing doesn't like the heat and speed.
vital acorn
yes. This isn't actually CPAP tubing, I couldn't get that to last more than a f...
had a similar issue with actualy cpap tubing what im using with archetype seems to be holding up much better while also being larger ID over what the VZbot tool head used.
yeah thats what the vzbot toolhead uses. idk what the temp rating o what i have is but we shall see if i need something more fancy?
uses size wise
vital acorn
its already sound with pla lol. idk how much worse it can get lol.
wintry swallow
Increase the infill?
You could also pull the surface off the M5 hole up so that it sits flush with the top. That way the bolt is providing some rigidity.
