DUET WIFI for dispenser machine

[dc42]

If the power consumption is only 4W or 4.2W as specified in that data, you can run it directly from a fan output.

@dc42
Looks like it is 4.2W as they don not mention any other consumption only for solenoid.
So basically I could control dispenser with M106 S0/S1 and fan outputs if I understood good.

Another thing that bothers me is G-Code generating. What I need is basically a line in space.
It is all clear with 2D lines. I generate G-Code. Edit it manually when to start and when to end dispensing. I make some macros to find X0/Y0/Z0. Wollia.
What is more interesting its 3D line in space. I can draw it, but I dont really understand what program to use to generate Gcode for 3D line.

Anyone has experience with it?

@dc42 I have a question.

I want to use 12V fan output to control 24V 4.2W (166mA) solenoid.
I would use booster for 12V output to have 24V. It will become ~400mA.

Am I allowed to do that?

I don't advise that, because the boost converter will have a high starting current, which might blow the mosfet. Can't you either use a 12V solenoid, or power the Duet from 24V?

@dc42 ok, going to buy 24V power supply. Will be less problems.....

[Alishkus]

So its is working

Will update on process of project as its pretty nice use of Duet Board

[Alishkus]

@dc42 can I have some consultation?
Machine is working (only compressed air hook up left) but I have strange behavior....

When I upload Gcode duet executes it normally, buuuuut it wont execute -X lines.... So it moves only half X distance needed. Am I missing something here?
Head travels from X100 to X0 and then it decides to move to Y direction...

[dc42]

Have you used M208 in config.g to define the X axis limits?

[Alishkus]

@dc42 and yes you are right Thanks

[Alishkus]

Look at these perfect lines :))

Machine works, however Fusion 360 is still not really suitable for Duet board. I will try to do some configuration on Fusion and if it will work will post here
