Trianglelab Matrix Extruder somebody?

[Chriss]

Hi *,

Let me come back to the topic.

Does anybody have some infos about the shipped thermistor? (24V)

I have the golden (brass) tube and a spring at the end of the cable. It looks like :

I'm totally confused now.
Does anybody have some settings which work fine? Is anybody willing to share them and ideally the "M307" for the hotend. I have them connected to a toolboard which can not auto tune the pid.

Cheers, Chriss

the thermistor is not 24v. only the heating element is.

they write they ship the thermistor with a Thermistor Semitec 104NT-4-R025H42G.
this is the same as the e3d one.

if you connected them to 24v, you will have destroyed the thermistor.

@Veti

Hahaha.... well the amount of destruction depends of the current than.
Enough fun for today, I mentioned the 24V because I'm not convinced that the guys from copyland send the same thermistor whether it is a 12 or 24 Volt kit. Thanks for the hint, I did not see that. the German translation drives me creazy.

if anything it would depend on time; as the thermistor has a negative temperature coefficient its resistance would decrease as it heats up, causing the temperature to increase. if left long enough both 12v and 24v directly connected to a ntc thermistor would cook it.

Not if your source will deliver 0.001mA only.

i don't suspect you'll find many of those on a duet

[Chriss]

@bearer Well, at least @PCR has one.

[PCR]

@Chriss i am only using PT1000 ones ;D

same here.

@Veti @PCR

Nice... thanks.... I will walk though the valley of tears than...

So you guys on the other site than.

[A Former User]

P1000 (and PT100) have positive temperature coefficients so they're inherently safe in that regards.

First the Matrix then a hemera. But Not the "new" one.

[Chriss]

Hey guys....

What do you guys use as steps at M92 for the matrix thingy? I use exactly 300 at the moment, they mention 336. :? I'm a bit lost now... My setting seemed to be OK in the past but I have a lot of problems since I changed the filament.

Hi there,

if some of you are still interestet in watercooling the Hemera, I might have something for you: https://www.dold-mechatronik.de/mebs-Hemera-WaCo-Mod-PRE-SALE-special-price-Available-from-2932021

Have a nice weekend.
