Just curious - Nova hotend with 100w heater
-
100w seems a bit overkill. The 50w heaters I use get to 200c in 45 sec and 370 in 2 minutes. We all love more power though

The difference would be in the PID phase. Will temps be more stable? Or will it overshoot more? It depends on the thermal conductivity of the heaterblock; how good the contact is between heater element and block and last not least, the distance of the temp sensor.
Wondering, if Nova just took a 12V 25W heater and labeled it 24V 100W?
-
@o_lampe AIUI the nova heaters are special custom ones. Vlad puts a huge amount of effort into the engineering for these hotends!

I don't have the slightest idea why 100W is needed, but I don't doubt that they're actually ~100W.
I use 50w heaters on magnums doing 30mm3/s with 70W of CPAP air (sorry, don't know how much I'm blowing) pretty much on/around the block, and i'm only at 50% duty cycle of the heater. I'd expect to have a bit more trouble with a mag+ doing 90mm3/s, but e3d only uses 80W for their chungus of a Supervolcano, and still flows fine.
The more important bit of "why 100W" - if you get a stuck mosfet, 100W will do some absolutely incredible melty things, copper block be damned. That's what really sticks out to me

Guys, don't get caught up on the heater wattage, they offer 60/80/100...
I'm more interested in how this is working and if any of you are using it.. the few videos that are out there seem very promising, easily printing at 300mm speeds.
It just doesn't seem very popular at the moment.
-
Just answering the given question.
Toolspeed doesn't give the entire story. - Volumetric flow (and quality of it) is what the hotend is providing here - 300mm/s is irrevelant, the e3d volcano can do that with .15mm layers using a .5mm nozzle, for ~24mm3/s in flow.
I've heard/read mixed items about it. The owner hasn't had exactly a spotless record of behavior when interacting with the community.
The other reason is that it uses all-custom parts. No compatibility with my library of nozzles or other parts. If i want a new nozzle for the nova, I have to pay their price, and frankly, many of us have decent libraries of e3d/slice compatible nozzles that would be just useless.
-
Sorry, I was being lazy, I do understand printing speed is not the be-all end all, but rather volumetric flow is.. some are getting ridicules volumetric flow on these hotends, from HEVORT to NOVA guys.
I couldn't care less if the creator is a "nice" guy or is abrasive. I also have investments in E3d, but am not adverse to try something new and it seems the Nova is a much cheaper high end unit when compared to Slice Engineering.
So I take it no one here has put hands on this unit and can provide any feedback?
-
We don't use the Nova hotend, but we do have a Slice Engineering Magnum+ with two 50w heaters setup on a 16"x16"x24" machine. We haven't got to use it much yet though - heavy testing should start next month.
Compared to the Magnum:
-
A user on the jubilee discord says it jams in warm/heated environments.
Prints PLA fine.
Sounds like you should buy it and report back. I'm tempted, but I don't really want to give the guy money.
@oozeBot I can't wait to get mine. I need more extrusion, magnum just aint cutting it

From the looks, I'd be afraid to brake or bend the heatbrake.
I like the Mosquito better, because of the 4 posts at the corners. (no hands on experience on any)
