That was it, that was the problem.
Thank you so much!

Update tom my previous post.
I had to connect the Duet 3 6HC to USB and to a laptop, and update the firmware using BOSSA.
Everything now works correctly.

Hi everyone,
This is my first post here on the forums, therefore I will start by saying „thank you for having me!”.
I own a Creality CR 10 MAX (which is also my first printer), received back in May this year, and so far I have performed a series of modifications on it. I have modified it quite a bit: converted to DirectDrive using hardware from TriangleLabs, changed the bed to a mirror one, added LED lighting to it, connected an OctoPrint, webcam, etc.
During my DirectDrive conversion, I used a brand new NEMA 17 1.8 degrees, 25mm pancake motor which I installed and configured with VRef modification, it worked well until the beginning of October, when the motor stopped working.
Its behavior was pretty weird, it rarely responded to commands sent to it, and when it did, it just made a grinding noise and would not spin at all. I took it out of the DirectDrive mount and tried it outside of the mount, it would spin when a command was sent to it, but would have no spin force (I could stop it by squeezing the shaft between two fingers).
I believed it became defective, so replaced it with the heavier and more powerful Creality 40-42 motor which was the default Bowden extruder one. It worked was too heavy and but pushed too hard, at some point bending the filament inside the DirectDrive, which required me to disassemble the whole thing. So I bought and installed a new Pancake motor, this time from Bondtech.
It worked for three weeks.
Earlier today, i started a print and realize I had forgotten to adjust the first layer height, so canceled the print and resliced the model. Upon attempting to print it again, the extruder motor would not spin. Troubleshooting revealed that it started suffering from the same issue as the previous one.

TL;DR: my printer chews through extruder pancake motors and I suspect it's something the driver or motherboard does.

So I am looking at fully replacing the motherboard with a Duet 3. Since I am a beginner in this, only having performed basic modifications so far, I am wondering what should I buy other than the Duet 3. I am looking at a complete solution, that is the motherboard, a nice screen, and whatever else is required. Looking for recommendations, I plan on placing the order in the next few days.

Thank you in advance for reading my wall of text and for your responses!

Hi everyone,

I apologize if this had been discussed before, however my weak search-fu on the forums yielded no specific results, so here I am, making another potentially-annoying topic

At any rate... I have a CoreXY printer (RatRig V-Core 3) with Duet 3 6HC, Toolboard 1.0 (not yet installed) and PanelDue 5i. Everything is installed, configured and works well.

With that being said, I have been looking at beefing up my part cooling fan, because at high speeds and accelerations, part cooling is lagging, even with a 6K RPM 5015 blower at full speed. I have the possibility of installing a high powered 12V fan, but its current rating is 2.3A - therefore I need some help correctly installing it.

I can either buy a dedicated 12V Mean Well DIN Rail PSU for the fan itself (example), and only connect tacho and PWM pins to the Duet 3 (would that work?). Alternatively, if you think it's possible to connect and power it from the Duet 3 directly, please let me know how to do so. The hotend cooling fan is 24V, by the way.

Thank you in advance for your help!
