@Veti

they are a little older and weaker than I need, I decide to pick up these

https://www.moonsindustries.com/m/p/nema-17-high-precision-hybrid-stepper-motors/ms17ha4p4200-000004611110015912

I required a 34 max millimeter length
They should do the trick - replacing the stock ones of a Cetus MK3 - Proof of concept

Thanks guys

@Phaedrux agreed lol - test until just to touch and a bit lower to keep just high warm

Tks

b

Is there a way to test the stepper motors amperage, power, to see what its specs are via commands

Assuming you have a stepper motor that you have no idea what the specs are, but you want to find out

That would be cool

@bearer A little earlier research, I would’ve figured that out,... WTF lol

So far so good, carbon fiber nylon.

after the fix, I can print without inverting first

This is basically a a Pinto,With new hardware worth more than itself

Thanks Gentleman!

@supset shit, is that it,WTF

@Phaedrux

My figuration

Is

Y = axis mounted on Z
X = bed plate axis
Z = vertical axis of course

Are you possibly sayin my X and Y are reversed

Should be?

Y = bed plate axis
X = axis mounted on Z
Z = vertical axis

Very possible, I just followed the schematics from the Cetus MK 3 drawings - which is the base cord hardware - just replace the extruder, Hotend and motherboard

Actually that would be cool if it was, because that would probably solve the problem

@Phaedrux Low end on the side of the stepper motor like X axis

pointing to my zero origin

@Phaedrux

Standard configuration and a G92 set Z zero position

Z and X seem to be OK
Y seems to be inverted

@Phaedrux

X Low
Y low
Z high

Anyone know what this phenomenon is, print is correct in position in Cura, when I print it prints inverse mirror it’s self on the Y axis

In the reprap configuration tool and the printer all axises are in moving forward Direction Correctly

my zero origin is front left side of the build plate
Which is the same spot in Cura

BUT!!!

the Y and X axis are flipped - definitely an Visual indication of what’s off,... but the question is how do I sync it with my printer Y and X axis

Cura’s X is my Y
Cura’s Y is my X

Thoughts Oh great duet 3D forum

@Phaedrux - generating a M307 temp model range - for that selected - nozzle temp limit - would be nice

People are using high temperature filaments and require 400 to 450 C temperatures

I’m using a mosquito magnum + high temperature thermistor + 50 W 24 V heater cartridge

And cannot reach 400 C plus temperatures, continuously trying to figure this out

PLA is for amateurs - High temperature filaments Ultem 9085 / 1010 - PC etc

https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control

@bearer i’m relatively new at this, learning quite quickly, thanks for your help, we’re almost there I think, copying your config Code will work?

@bearer said in Free working Cetus MK3 - Thermistor cap!!!:

“a pot”? Where did you turn down the ohm, is this a file configuration

@bearer LED? On the motherboard?

sensor - you mean the heater cartridge?

@bearer 290 C has maintain temperature accuracy, but I will try the 305C, to see if it stays active, if that’s what you mean, I will test

It just seems to plateau, it simply won’t go any higher, weird it’s a 50 W heater cartridge by slice engineering combined with the 450 C thermistor and the mosquito magnum so it should reach the 450 C temperature - unless the firmware or the duet 3-D 2 Wi-Fi board can’t handle it

I’m running 24 V 300 W power supply

@dc42 The fans are focused on the heat sink, and far enough from the heater block - we are still 140c off Mark,...

@dc42 can you confirm reprap and the duet 3D 2 Wi-Fi board can reach 450c - if so, I may have a defective heater cartridge, can a heater cartridge partially work? what do you think?

@dc42 The previous heat creep was due to the fan being off - ( M107 command in the print G code )

that has been corrected and is always on, now it just plateaus at 305c

That’s right I’ll give you my old, but in great condition Cetus MK3 + A bunch of spare brand new nozzles print bed and leftover new parts from my build free ( you pay for shipping wherever that may be )

Solve my heater, thermistor, temperature issue not reaching the expected 450 C

It’ll be fun, why not!

Brian - Maxing out at 305c ish - ideas thoughts?
8-2-2020

Can this hardware and firmware reach high 430-450c temperatures? That’s my requirement, any assistance would be appreciated - i’ll get there eventually, but with your help, sooner would be cool!

NOTE: is it possible to partially burn out the heater filament, I added a secondary duplicate fan to the heat break, because of massive heat creep all the way up to the Bondtech extruder melting the bottom mini plastic protrusion mounts - had to drill out the filament path all the way through the heat brake and heater block - three times - ( I know, WTF ) - in case this has any bearing On the matter!

Here’s my set up

• Duet 3D 2 Wi-Fi - latest duet web control - running reprap 3.1.1

1. Mosquito magnum
2. Bondtech BMG-M ( not relevant but here it is )
3. Slice high temperature thermistor 450c
4. Slice 50W heater ( 24v )
5. Configured slice thermistor with the reprap configuration tool to 445c .json file reflects that
6. hotend thermistor and heater are properly installed and secure.
7. 24V 300W - Power supply

objective is to print high temperature filaments
Ultem 9085 / 1010 etc - and any other super plastics composites I can find

Maximum heat temperature

Thought I was getting closer
temperature tuning
started with - 220 / 270 / 290

M303 H1 P1 S300 ( One resource I used )
https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control

It’s either configuration, reprap has no adjustable temperature limits - bad heater cartridge, bad thermistor, or specs are unreachable

Or just something absolutely simply stupid
Any help would be great, thanks man!

@fcwilt it seems the M143 Command possibly works, I commented it out, and got this, default 285c limit

I put it back and restarted, and the error disappeared
