@T3P3Tony

Thank you for this information, I am happy to know that I can keep my 48v power supply.

Concerning the fuse problem, this is resolved, I replaced the internal fuses identically (2A), and I installed inrush current limiters (2A) on each VIN power line (+) coming out of the tool distribution card.

Thank you both for your help!

I have another question regarding the M23CL (maybe create a new topic):

• Is it possible to configure a fixed origin with this type of closed loop motor, or is an end stop required as with standard motors?

I still have to do the PID adjustment of the motors, they are already running great, I can't wait to start manufacturing!

This is my first NC with a duet card, I am very happy with the duet products that I use on many 3D machines!

Sorry for the spelling mistakes, I'm French

Thank you for your quick feedback, it is very much appreciated.

The motors are connected to the Duet 3 Tool Distribution Board which is powered directly by the 48v power supply, they are therefore energized as soon as I turn on the electrical cabinet (red M23CL LED flashes), I checked the voltage of the cable power supply of the motor, I am at 48v permanently.

The motors are equipped with a brake, I noticed that the brake is 24V, wouldn't it be a problem to power the motors with 48V?

The fuse blew when I engaged the motors (M17 Y X), releasing the brake.
Could switching on the motors create an overvoltage and blow the fuse?

Thank you very much for your help.

Re: M23CL no led up!

Hello everyone,

I am currently building a CNC,

I have a problem with my M23CL motors with brake.
the internal fuse of my two motors has blown.

I don't understand where this could come from, the motors worked correctly after their settings, correct movement on X and Y, and this evening when turning on the machine, I made a homing and clack, no more red LEDs, no more movement!

Diagnostic = INTERNAL FUSE failure

I would like to replace this fuse but I don't know these values, could you please send them to me.

So could you tell me a possible cause of this problem?

I use a high quality 48V power supply. The motors are connected to a Duet 3 Tool Distribution Board and are powered by it.

Thank you for your help
