Timer on duet.
-
Hello duet friends,
I don't use my duet 3 mini, so I want to make it work for something else.
I would like it as my home grow Computer:D
Is it possible to adjust a timer. Like I want move an axis to a specific time.
And is it possible to connect a pH sensor? Or maybe a electrical trigger...
Thanks a lot -
@IndeX4D I think there are a few forum users who have hydroponics setups, though I don’t know how many use a Duet as a controller. @deckingman maybe? See https://forum.duet3d.com/topic/33823/possibly-another-world-first-duet-controlled-machine
You should be able to connect most analogue sensors, if they give an output in 0-3.3V. Triggers shouldn’t be a problem. You will probably need to write the Gcode you want it to run, using meta Gcode to wait for inputs. See https://docs.duet3d.com/en/User_manual/Reference/Gcode_meta_commands

I do have 3 hydroponics towers but I control everything with an ESP32 dev module which is considerably cheaper (and arguably better suited) than a Duet board. I did experiment using the (duet controlled) printer to germinate seeds but that was just heating the bed to circa 30deg and turning on the lights.
I appreciate that the OP has a Duet mini kicking around but I doubt it'd be much use (although I guess it depends on what he wants to do). My ESP 32 has 4 Dallas temperature sensors, 3 fluid level sensors, a 4 channel relay (one for each nutrient pump plus an air pump, 3 wet/dry sensors, and a door switch. The nutrient pumps cycle on and off with the "on time" varying with ambient temperature and whether the sun is above or below the horizon. If a pump runs but the associated wet/dry sensor in the top of each tower remains dry, then I'll get a notification on my phone. Likewise if one the nutrient tank levels gets low. I use an old Android tablet to display a dashboard showing the status of all the sensors as well as providing touch screen manual control. This is all easy to do with an ESP and home assistant but would be difficult using a duet board.
