Hello All,

I am currently building a redesigned variation of this pump:
https://www.appropedia.org/Open-source_syringe_pump

The main advantage of this for me would be to control multiple pumps synchronized by G code.

I am currently using duet electronics for my 3D printer and I am very impressed by the customization options.

Is it possible to configure a duet WIFI to use all 5 stepper drivers as an axis with no extruder and no end-stop and minimum-maximum axis length? If so how would the config G code look?

If possible I would also like to use the heater channels to have multiple temperature control loops (basically all four channels should be controlled like a heated bed either bang-bang control or with PID).

Thanks in advance for the help. I really appreciate the mod ability of the DUET software and hardware.

Hello Duet team and Co users,

I am currently building a fuildhandiling robot with a duet Wifi and a DUEX5.

There are serveral cases here where it would be nice to controll air flow and air pressure with the duet.

It should be possible to use the M308 with Y parameter Y"linear-analog" to define any kind of sensor that has a 0 to 5v output.

But is it also possible to couple an PWM output controll loop to this?

For example using a simple on/off controll to keep a pressure in a certain range.
Or using PWM on an air pump to maintain a certain flow measured form a gas flow sensor.

Is this possible? And how do i set it up?

Thanks in advance for your responses!
