@droftarts Yeah, I can do that when I get a chance next time tomorrow when I'm, back at my lab. I just replaced it with a new toolboard for now and it worked fine.

@jay_s_uk Yeah, everything else on the mini5 is still working. I guess I will try a new tool board and report back if it's still not working.

Hi everyone. So silly mistake, I accidentally switched ground and Vin connection on the DUET Toolboard 1LC. I am using a DUET3 Mini mainboard at 24V Vin.

While I had no motors, heaters, etc connected to the toolboard or mainboard, the reverse voltage popped a component on the board with smoke. I'm guessing it is one of the voltage regulators as the pop and smoke came from the accelerometer side.

I had the wiring on the CAN bus connected and I'm wondering if the CAN connector/functionality on the DUET3 Mini Mainboard would be affected in anyway? For the toolboard I'm just going to buy another one but I wanted toknow if there is anyway to know if the CAN bus on the DUET3 Mainboard would be affected (besides just trying a new toolboard)

Thanks.

@cad405
would love the code you have so far. Thanks.

@chrishamm Will do. Thank you for the prompt response.

@chrishamm yes the duet3 package i have is an older model. shipped early 2020 I think.

For reflashing, is there any special process I need to do first. I.e erase and reformat the card?

@ravs99 **Start4.elf

Hello everyone. I have a DUET3 MB6HD and raspi 4b. I plug the sd card from the duet into the raspi but I get a message on the boot screen saying Str4.elf not compatible, please upgrade firmware. I don't have the duet3 connected via the ribbon cable, its just the raspi.

Any advice?

@deckingman existing sliders? I do not seem to find any. maybe I have it setup wrong? Heres my config file.

@ravs99 the mixing ratios have been working for me for the most part. I just wanted to know if there is any easy way of bringing up sliders in the DWC for fine tuning

@deckingman @o_lampe Thank you for the insightful discussion. One thing I forgot to mention that I'm using the mixing ratio functionality in a different way. Im using a pellet extruder attached to an external feeder. For now, I have assigned the feeder as a second extruder so that it synchronously feeds pellets to thew pellet extruder. This is not the ideal approach and I would have done it through meta G code commands but I'm waiting for async movement to be a thing in RRF 3.5 so I gotta stick with mixing ratios for now. Thus I do not need the sum to add up to 1,etc

Sorry for that haha

Hi all. Is there anyway to bring up sliders on the DWC to control mixing ratio for multiple extruder drives for a tool?

Thanks.

@dc42 Ah i see. Yes i was referring to those closed loop expansion boards. In the g-code dictionary for M569.4, theres planned torque mode support for RRf 3.4. Was just curious about that as it may offer an opportunity for me to implement Tobbens semi-autocalibration which uses encoder readings from moving the hangprinter to known positions in torque mode on the drives and BLDCs. (but instead using stepper motor and encoders)

Any update or details on torque mode on the expansion boards for DUET3?

@dc42 will this "torque mode" be similar to the torque mode in O-drives that are used in the Hangprinter v4?

@grabercars Did you end up figuring out how to adjust your Steps/mm for your screw extruder. If so, would you mind showing me your process?

Thanks

@hebigt thank you!

@dc42 ah i thought as much. If I were to use a servo and the DUET's IO ports, how would I go about it? What are some recommended servos for the DUET3?

Thanks

@ravs99 or even at a regular interval regardless of filament extruded if that is easier

Hi everyone. If i wanted to turn a stepper motor (separate from the X,Y,Z,E axis of the printer) a specific amount after X amount of material has been extruder, how do I go about this in the daemon.g file?

This task is to be done while the duet is running a print job. Thanks.

@norder Thank you for the advice. That does sound like a better option! However, I want to know how to actually drive the stepper motor that controls the release of pellets from the hopper to the extruder (not the auger motor) in the daemon.g file. Is it as simple as making a new axis and then adding the appropriate gcode to move the motor X amount every 10 seconds or so in incremental mode

Thanks
