@droftarts Thanks!

@droftarts i found this: TDK MLK0603L3N0ST000.
Can be suitable? I know a man that repair smd elettronics but he needs the pieces...

@droftarts Hi Ian, after searching online for the replacement part, it turns out to be a filter—my mistake for not checking earlier! I haven't tried soldering it because I'm worried about touching nearby components and potentially causing more damage. Is there any way to get the exact part number for this component? I found something online, but you know, if it's not an exact match, I might make things worse.

Some news, .

This resistor (L7) doesn’t seem to be soldered properly. When it makes contact, everything works perfectly, but when it moves due to vibrations, the extruder motor reports that Phase A is interrupted.

Good evening guys, sorry, I think I’ve broken the toolboard :(. Is there anyone who does repairs? I’d rather not buy a new one.

A pin came loose while the printer was on, and it hasn’t worked since then. I tried with two different motors, a Sibor 14st20-1004A following the motor’s color code, and another stepper. Both give me the same error.

Thanks

Hi Ian,
thanks for the response. I didn't notice that there are two steps for the Z axis; one should have been Z and the other E. As for the motors, I currently had these at home and tried them out. I started with a current of 1A and increased it gradually for testing, and it ended up at 2A. Anyway, I will replace them soon with NEMA17 SUPER POWER (42STH48-2804AH). I'll try lowering the speed settings and see if anything moves. The command I sent was always G91 G1 H2 X10 F3000 G90, but I just copied the G1 part, etc.

Thanks
Nico

Good evening everyone!
I am finalizing my custom VORON printer, and I am testing the various motors to set everything up correctly. As for the Z-axis with 4 motors, I managed to get it working without any problems; on the first try, the motors responded well (Nema 23). However, I have been struggling for a couple of hours to understand why the motors on the X and Y axes are not responding. I have checked the wiring multiple times, and there seem to be no issues, although the console shows the message "Warning: Driver 0.5 warning: phase A may be disconnected." I changed the driver to see if it was damaged, but the error persists. I am attaching a video of how the motor behaves; both X and Y do the same. I am sending this Gcode "G1 H2 X10 F3000".

Video WhatsApp 2024-07-12 ore 00.17.41_3fb4bcf2.mp4 This happens when the motor is at rest, that is, when it has finished the Gcode just sent.

Thanks!

UPDATE 12.07.24
I switch M669 parameters in K0, just to try driver and motors. They works without any issues.
I can't understand why!

@droftarts Thanks, i'll try !!!

Have a good day

Nico

@droftarts I use 3 dotstar for the stealthburner extruder, so should be fine.
I checked the resistance of the wire and i get about 0.4ohms over 3 meters (the wire has a section of 0.25mm2).
Can i put a 120 ohm resistor in series with the wire?
This usually done in industrial machinery.
I noticed a GND_SHIELD connector, can I use it to connect the cable shields?
All my cables are shielded.

Thanks

Nico

@Chaos3d Thank you very much for your explanation, but I believe it is not suitable for my hardware.
@droftarts no worries, Ian, there are no problems. The printer is still under construction, I won't stop because of the LEDs!! I have connected them to the IO8 port of my 6HC for safety. There is one more thing I didn't understand. I need to make a CAN cable about 2.5 meters long from the toolboard to the mainboard. I am using a specific cable for the CAN connection; it is shielded, twisted, and very thick.!!
Immagine WhatsApp 2024-06-26 ore 18.59.12_156a208d.jpg

I have also kept the CAN terminals separate, as you can see in the photo, to avoid interference. Could this work?

Thanks

Nico

@droftarts Thanks Ian, that works.
All leds now are white. i tried some M150 to change color, but it not works. Surely it's my fault!

Toolboard connection:
DRIVE0 --> E0
IN_0 --> 3 leds
T0 --> original thermistor E3d
OUT0 --> Resistor 24V
OUT1 + OUT2 --> FAN 24 V
IO_1 or IO_2 --> klicky probe

I can't understand why it's a bit hot. MCU temperature: min 46.3C, current 50.8C, max 50.9C.

@gloomyandy I have updated all the boards (MB 6HC + Toolboard 1LC v1.3 + Raspberry Pi4) to RRF 3.5.1.
I searched online a bit and tried to do the programming with ChatGPT . I had seen something in the forum and it seemed to be somewhat similar

Good evening everyone,

I have a problem configuring the LEDs. I have an original toolboard v1.3, and I have connected them to IO_0. There are 3 LEDs, and I have attached a photo. I tried to write the .config file with the following lines:

; Led Neopixel
M950 P0 C"121.io0.out" Q500             ; Configura il pin di uscita per i NeoPixel con frequenza PWM 500Hz
M150 X0 Q3000000 D3                     ; Abilita il controllo dei LED NeoPixel con una velocità dati di 3MHz e 3 LED

One of the 3 LEDs is not working, one is green and one is white. I don't understand why. Additionally, I am getting this error:
Can anyone help me solve this problem?



Thanks in advance!

@Exerqtor Do you find it more difficult to communicate with a different board than the Duet? Or does it remain simple with the CAN bus and just a matter of assigning some addresses?
I didn't know that Annex was stepping out of the open-source project. If I see that it doesn't work well, I'll get the ERCF. Even though I've already built the trad-rack. My real issue is that there aren't many configurations for RRF, and I'm not very skilled in 'free' programming. I like to experiment, but I don't have any studies that could help me.

1171MG is a DIGITAL servo, I don't have much experience with servo motors, I will have to do some tests.
I hope to find some info on TradRack, there's a genius who should have done it on RRF.

Thank you very much!

Hi guys! I'm setting up my printer again
I'm converting it into a Voron 2.4 'giant' with the current print bed but in coreXY following the Voron project. I intended to add the TradRack to have the multi-color option. I need to purchase a 3hc board to connect additional motors for the Z axes. But I wanted to understand, in the TradRack configuration, you mount a servo motor 1171MG. Where do I connect it? How do I program it?

Thanks a lot in advance!

@gloomyandy didn't see
I m going to order a couple of RJ11.

Thanks

Hi guys!
I have just purchased a toolboard v1.3. Following the wiring diagram, I noticed that it is indicated to wire CAN 1, which is the one installed with the RJ11 connector. Observing the duet 3 6hc, I noticed that it has another CAN connector, CAN0. Can I use that one? I don't have an RJ11 connector on hand

Thanks!

Hi guys! I hope you're all doing well!
I stumbled upon this project https://github.com/Enraged-Rabbit-Community while browsing the web! I searched for something within the forum but found some confusion, and I would like some clarification. I have a Duet3 6HC, do I need to use this board https://github.com/gixxerfast/Canned-ERCF-board to manufacture ERCF? Can't I use a Duet 3 expansion like 3HC v1.02? Regarding configuration, can I use the macros I found in the forum?

Thanks to whoever responds. Greetings and happy printing to all!

@droftarts, @fcwilt

guys really thanks. Can i offer u guys a coffee?

See you!

thanks again!!!
