Trianglelab Matrix Extruder somebody?

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

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.

Chriss

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.

@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.

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.
