Solved R.I.P. hemera
-
Well after an extensive rebuild come to find out. That im one of the luck few to get one that has the bad gears.
Since the gears wont be avalable for an extended time i had to switch to a mosquito magnum hotend and bondtech extruder. . "Never say die"
So when i started up this time i got a heater fault
(Lack of settimg p.i.d.??)
I used the same 30w cartridge and same pt1000I have a 50a cartridge and was planning to use the existing 30a one i used before since it was working.
So i understand ....what should i do?
When you run a pid does it record the curve
(Run a g or m code to do this ?? )
The error was "heating to slow" ,,,, My assumption is the mosquito hotend need a larger heater and reset the pid????
Or would just setting the pid alone be good enough to start off with.
Last.... im wondering if i need to use a mosfet if i up the wattages of the hotend cartridges to 50 or 60 watts
A link to the pid procedure would be helpful.
Thanks. Ed -
I am guessing You need to tune PID. It is not that heater is too weak, but mosquito has different thermal mass than e3d heater block, so needs a little different PID settings.

Thats what i thought thank you its also looks to be ss steel instead of aluminum
-
@ziggymanpopo mosquito is not ss - it is nickel(?) plated copper

i also wanted to buy a hermera.
in the meantime i have ordered this

https://de.aliexpress.com/item/1005001525240599.html looks "interesting" too

What timeframe did E3D quote you for the replacement parts?
I have a hemera sitting on the desk, shipped after they allegedly fixed the issues, odds are it'll keep sitting on the desk for a while still. I.e. provided I get new gears in some reasonable timeframe I could perhaps part with mine.

@PCR
that version is all metal and would be a bit heavier.
in the mellow version only the front part is metal for heat dissipation. the rest is plastic. -
My supplier told me no more will be filled until poss jan next year im assuming the gear issue is more of a china supply and covid issue... for that reason im willing to be forgiving you gave the same issue of
Extrusion skips
Mine starts poping within 10 mm at the lowere speed -
I have "retired" x3 working Hermes (yes Hermes as these were the originals before the handbags were thrown) in favour of Omnia Extruders
Mainly because the Hermes is a pain to change filament on, and I feel the Omnia actually (in my opinion, with back to back testing) produces better quality prints than the Hermes.

That triggers my spidy sense, the last delay was not all covid - they also made a lot of changes to the gears/production to remedy the issues the first users had without saying anything until they announced new stock 6 months or so later.
January wouldn't be an issue for me, but I'll have to do some digging to see if I can take E3Ds estimate at face value.

Thanks guys
-
i have to say i am a bit disappointed with e3ds performance of late.
only offering the hemera with that large motor and not having a smaller option.
and i have to say other companies are coming out with similar products that look equal if not better
like the BIQU BX extruder. -
The lag time is also ridiculous i only see it getting worse with a secont lock down commong to England
-
E3D has replacement parts for Hemera, just contact them directly.

Search for the term HE?ER? (Sorry I have to cover this term. You should know how to search.
LOL, that's just sad. But crikey thats pricey, not that the genuine article is cheap but the savings vs risk seems less than favorable in that case.
Still interesting to see them catching up, thanks for sharing!
-
i am tempted to buy it.
the heatbreak looks different.
not like the hemera and not like a their bimetal one.
looks like part moscito. -
Looks like a hemera copy. I wasnt impressed wwith the quality of prints that it did complete.... so i won't waist any more time with this design but thanks for the input. Second the three most important parts to our printers are the electronics ,,the. Extractor and the hotend so i prefer the original just to suport industy
Look at the wonderful job this site does..
Wouldnt it be fair if we supported real products
Instead of copy's ...at least for those three items
I believe they have earned it -

yes, but they have been out of stock for months with no timeline when they will restock.
