Thanks, Bearer I did not have the int_5v jumper in place. She is powering up now.

@Corexy said in Extruder Stepper Choice: @deckingman said in Extruder Stepper Choice: @Corexy Ref the BMG/Mosquito combo, be aware that you need the BMG-M, not the standard BMG which has an E3D type groove mount. Yep, I am aware of that but thanks for the reminder. I just don't like that E3D mounting groove. It's a pain in the arse in fact. Totally agree about the groove mount.

UNSOLVED Duet 3 Thermistors showing -273.1

Please share your config.g file. Check your config.g file by runnig M98 P"config.g" to see if you get any error messages. One cause of all thermistors reading -273 is that there is a short between VSSA and a higher voltage, for example a heater wire. Such shorts are quite common in 3D printers, which is why Duets are protected against them. So disconnect all thermistors from the Duet, then test using resistors again. If you still always get a reading of -273, check the resistance between VSSA and GND. It should be only a few ohms, it's the resistance of the VSSA polyfuse..

@dc42 said in Duet3 Expansion Board 3HC - No CAN-Connection: I was thinking the the original issue might be related to using more than one Y motor. I'm using 3off Y motors. But thinking about it, they get re-mapped to individual axes for homing so you could well be right.

@dc42 Currently the fans are 12v because I am using the Noctua 40mm fans and they do not come in 24v versions. Am I correct in thinking that the switching for the fans is done on the GND though? @oliof I am currently using a 15 conductor cable and have the wires for the stepper coming out separate from the DB connector. I would prefer to have them in the connector but the DB15 connectors that I bought ware just so big that it really compromised the design intent of the extruder. Here is how I am currently running. 15 conductors: 4 for heater 2 for Thermistor 2 for HS Fan 2 for Part Fan 4 for Stepper That comes to 14 of the 15 used. So now I have come up with a way to add a filament runout sensor built into the extruder just above the drive gears so I was thinking if I can use just one power wire for the fans that will free up one more wire to have two free. Here are some pictures of my design. It is based on a bondtech BMG but is a highly modified design. With tool plate Tool plate removed you can see the DB9 connector This is still in the prototype phase and have been refining the design over the past few months but I have been printing with no issues now for about two months and been able to print PC with no jams or heat creep. The tool mounting and locking system is based on a design by PoofJunior over on Thingiverse that he did for his Jubilee printer.

hi Yes, I have all those documents already, and have used the servos connected with Arduino uno and Arduino due. I just want to know how can I use them with the Duet wifi ??? a sketch would be appreciated for the connections, or since I know how to connect them to the Arduino board, is it possible to use the Arduino with the duet wifi ?? if so how ??

@Sp00kie13 FIRMWARE_VERSION: 2.03 Well, that largely explains it. I think you have a WorkBee machine, and if you are using their firmware, they use the older version 2 RepRapFirmware. The commands you’re sending are for RRF v3, and what I was testing. What you need is the command in RRF 2. You need to know the fan PIN number, disable its default fan assignment, then assign it to the laser. See https://duet3d.dozuki.com/Wiki/Using_servos_and_controlling_unused_IO_pins which shows the PIN numbers. So try: M106 P20 I-1 ; disable fan0 assignment M452 P20 I1 F100 ; laser uses fan0 pin, PWM frequency 100Hz Let me know if that works. Edit: you still can’t control the pin with M106. The laser should fire with G1 moves, but I’m not sure with firmware v2.03. See the laser guide I posted earlier. If you can give feedback, I’ll update the guide. Ian

Are you running latest firmware on both main and expansion boards? use M115 to check. latest is 3.1.1 on the main board and 3.1.0 on the expansion board.

I think you have to invert pin by adding (or removing if you already have it) ! mark in M574 command. Another way is to use it as NC switch (recommended) instead of NO. To do so connect U to ground and leave G not connected. But remember for future - dont do that if you have any other components populated. It works only if you have only microswitch on that switchboard and nothing else!

@droftarts I plan to do the same with my IDEX! I would also like to reference both tools with one piezo sensor each. Where do you write these commands? Does all of this come to homez.g?

Duet3D Magnetic Filament Monitor Drifting Sensitivity

Been a crazy few weeks since I had an update on this issue. I gave the monitor unit a through check and it was fine. No issue with the magnet or the hall effect sensor. Turns out the issue was the extruder stepper motor. It was skipping steps here and there which caused the error buildup. Replaced the motor and just completed a 32 hour print with no issues. The filament monitor was performing correctly the whole time. Lesson learned for me, but I hope this helps anyone else having a similar issue. Thanks for the suggestions and the time.

Duet 3 is 5V tolerant, so even if using an old version of BLTouch it does not need to be set to 3.3V.

To be safe I switched the heater to E1 since this is a delta printer and I wont be installing a dual nozzle system. Thanks for the insight!
