Just found this guide, It should clear up many questions: https://forum.prusaprinters.org/wp-content/uploads/wpforo/default_attachments/1596858738-ZMK3s-Duet2W.pdf

Looks like they used my end print jingle

@dc42 said in Duet3d DHT 22:

BTW we already allow a redundant "0." prefix to be used in front of drive numbers on Duet 2. I will probably allow the same for port names in a future release.

All working fine for me now - Thanks!

So, I will wait for the Duet 3 Mini, for the TMC2209 with steathlchop

@R3play
that looks fine

here is a guide on how to calculate it.
https://duet3d.dozuki.com/Wiki/Choosing_the_power_supply

@wifibeagle that can easily be incorporated though as endstops can be changed to triggers at the beginning of a job.
Or you can permanently have them set up as triggers and change them to endstops at the start of the homing sequence and then put them back as triggers

Crydom and Schneider Electric are both reliable brands. I would add that amazon has a big counterfeit product problem as well.

I have my filament in the print chamber which is well enough sealed so it helps keep the filament dry, and the chamber heater is standalone from the duet and controlled on its own, it is linked to a temp/humidity sensor in the chamber which is set to trigger the chamber heater if humidity rises above a certain threshold.

Simple, uncomplicated and just works

Sorry for the delayed answer. And thanks ALOT T3P3Tony, it was the beta firmware that caused the issues. Flashed back 3.1.1 and everything works like it should. Amazing board you have made, i have to say!!

Nice work around 👍
Thx David!

@Phaedrux Thanks I will have to try that. It would mean the slider on my web interface wouldn't work but that doesn't matter as long as the print gcode is handling it.

I saw a YouTube video on the compressor by AvE and I thought it was perfect for what I needed, only I didn't think of how to control it. 😅https://youtu.be/eEF-owkyI-o

First part came off the printer today, functional but I have a lot of tuning to do. now I can add post possessing gcode on the to do list as well.

I've designed a case for Duet 2 + Rpi + 7" screen + 2x SSR's for custom dual zone bed heater. Here is how it looks like

see
https://duet3d.dozuki.com/Wiki/Using_external_stepper_motor_drivers

the duet 3 external stepper board has just been released

https://duet3d.dozuki.com/Wiki/Duet_3_Expansion_1XD

i cant find the datasheet for the motors.
do they come with a stepper driver?
are the bipolar?

@jckray did you checked the SD socket to CONN_SD? Did it work?
what did you use? I have the same issue and will fix it in the same way but I don´t know which SD extender is the right one.

@CaLviNx I would say the biggest problem is that people are being pushed steered into buying an RP1 needlessly. On the Duet 3D web site, the description for the Duet 3 main board states..........

"The flexibility of configuration and advanced features are enabled by our innovative RepRapFirmware 3 running on the Duet 3 Mainboard and our customised DuetSoftwareFramework running on a single board computer."...............

There is no mention that the mainboard can be used in stand alone mode. That's why I mistakingly bought an RPi at the outset. I was also told at the time, that the Panel Due wouldn't work with Duet 3 so an SBC + HDMI touch screen would be the only way to control the machine "locally".

So for anyone not familiar with Duet products, it is somewhat implicit that an SBC is a necessity. Whereas the reality is that an SBC is by no means necessary but might be a useful accessory to add at some time in the future when somebody has thought of some practical use for it.

The start is not in there since it included the password... as far as the interpolation this works, I'll clean it up later, I am more busy with the heaters right now...

@Gerrard said in Consolidating supply and GND for hotend:

Can I run 2 laser filament sensors from the 3.3V and GND of one pin (say E0), then use the input (E0/1 STOP) pins from E0 and E1.

Yes the filament monitors can both be powered from the same 3.3V and ground connection

Then, can I run a 12V and GND from the Power In terminal to the hot end to power the fans and LEDs, and run the Fan's PWM signal pin to the FAN0- and FAN1- pins?

Assuming you are using 12Vs to supply the whole system then you can use a single source of 12V, and switch the -'Ve sides (i.e use the FAN0- and FAN 1- for the two fan 've connections, possibly use fan 2- to control the LEDs.

caveats

You need to ensure you don't exceed the limits of the fan mosfets (1.5A max) There is a potential failure mode where the VIN voltage shorts onto 3.3V. this is more likely if you bundle all the wires up into the same bundle. You mention you are using a ribbon cable. This can be a good solution but be careful to manage the strain relief and flexing to it does not break and short. Also check the max current rating of each of the conductors in the ribbon cable (probably 1A max or less). If you end up putting 12V and the return GND over multiple conductors then if one breaks, the other ones will end up carrying more than they are rated for, and get hot.

no need to reply fixed it
