@droftarts

So just to clear things up.

There is one jumper just to switch between 5V and VIN on FAN2
And the other Jumper is to switch 5V and VIN for FAN1, FAN0 and ALWAYS-ON FAN?

If this is the case, is there a way to set FAN2 as extruder fan so it will turn on when the hotend gets hot? (what now is the case with FAN1)

@droftarts

oh man..... thanks! I thought FAN2 was the always on fan because it a had a seperate 5V/VIN switch...now it all makes sense...

@phaedrux

I think this is how to measure from the 3 pin connector right?

@phaedrux

Yes, the 2 wires are connected to the FAN2 pins as shown in the 3rd picture

@phaedrux

Here you can see I only have 0.3V right now on the 5V connector

@alankilian

yeah all the leds (VIN, 5V and 3,3V) are on

@alankilian

Is there another way to test if my +5V is working?

@alankilian

What kind of board do you have?

Oh yeah forgot to mention... It's a Duet 2 maestro.

Is your 2-pin fan-voltage-selction jumper working?

I guess Its working, he looks fine and if tested another jumped with the same results.

Do you read 5 Volts on the 5V pin in the three-pin fan voltage selection jumper?

When testing between the ground (2-pin) and the 5V (3-pin) I got 0.15 volt.
When testing between the ground (2-pin) and the VIN (3-pin) I got 0.22 volt.

Can you check the continuity between the center pin of the fan-voltage-selection and the V-FAN pin on the always-on 2-pin fan connector?

Yes I do have continuity between the center pin and the V-FAN pin on the 2-pin

Hello everyone,

Right now I have a 24V 30mm extruder fan connected to Fan 1 (turns on when temp exceeds around 40 degrees C )

Now I have bought a 5V 40mm Noctua fan to replace the 30mm fan.

I wanted to connect the fan to the always on fan connector set to 5V but the fan didnt do anything. when using a multimeter I read 0.2V on the always on fan pins. when I switch the jumper to VIN (24V) I still read 0.2V on the pins.

Is there something wrong with the board, or do I need to turn some settings on to get the fan to work?

It would be strange if there is something broken because I have never used the always on fan pins before.

Thanks in advance,
Michel

Yes it's a 3D-printer store (Reprapworld).
I will just send them a message to ask them about the inductance.
If they don't know I will just give them a try and hope for the best.

Would this be a good motor for the maestro?
I know the inductance should be below 4mH but that information is not given.
Should the motor be good or should I look for something els?

Thank you. I was searching for that calculator but I wasn't able to find it.
You are deffinently right about the speeds. most of the time the printer wont reach anything near 300mm/s but I just wanted to make sure the limit with 0.9 degre steppers did not go as low as 150-200mm/s. But I just checked the calculator and even with 0.9 degree steppers I should be able to get 300mm/s so thats a good thing.

Thank you for the replies. In that case I won't buy the 2.5A stepper motors and I will look for some lower amerperage steppers. The only problem I can think of is that the maximum print speed with 0.9 degree steppers is lower than 1.8 degree stepper.

My (cartesian) printer is pretty high end with a metal frame and lineair railses on all axis.
Right now I have 1.8 degree steppers with 16 microstepping with interpolation and I have done prints before at +- 300mm/s.

What would be the max print speed I can get with 0.9 degree steppers?

I have a pretty good DIY 3D-printer but I still have some wierd vertical lines and I think they are caused by the cheap stepper motors I got from China. So I want to upgrade them to some better stepper motor. At the 3D-printer store where I always buy my parts and filament they only sell a set of "SL42S247A" stepper motors.

Motor specs given on the website:

Length: 47 mm
Weight: 360 g
Voltage: 3.3 V
Type: SL42S247A
Holding torque: 5 kg-cm
Nominal current: 2.5 A
Shaft diameter: 5 mm
Stepper motor format: Nema 17
Step angle: 1.8°

Will this be a good motor for the Duet 2 maestro or will the current be to high?

My Duet 2 Maestro is cooled with a fan and the MCU Temperature does not go over 30°C with my current setup with 1.7A stepper motors.

@Veti
I can't find anything about this on internet. Also I can't really see a C value in my M569 commant.
this is what my M569 reports:
M569 P0: Drive 0 runs in reverse, active low enable, step timing fast, mode stealthChop, ccr 0x00053, toff 3, tblank 0, hstart/hend/hdec 5/0/0, tpwmthrs 1000000 (0.0 mm/sec)

I still have the same problem so all help is still welcome!

I have tried another type of stepper motor and it does the same thing.

Isn't there a way to change the frequentie in the software or something?
I would like to stay away from dampers if it isnt really nessesary

My power supply is 24V.
