waterjet cutter and duet

Aurimas

Hi,

has anyone used Duet boards to build a waterjet cutter?

Just thinking aloud - I don't it is much different from CNC and/or laser. M3 and M5 will turn the flow and off
rest of it is per normal.
what is needed is the postprocessor definition for the Fusion360 or alike.

@Aurimas I wouldn't put it on the same page as a Laser or Plasma cutter.
The whole gantry must be much stronger because of the backpressure of the waterjet.

@o_lampe what does the gantry have to do with Duet controller board?

I wouldn't use a Mini5+, because it takes strong motors to move a heavy-duty gantry.

I don't see how you are contributing to this topic. I follow the rule - If I have nothing usefull to say - I say nothing.

I imagine you’ve done some research since you originally posted this topic-

In principle, yes you could use those M codes to open and close a valve. You should probably start with M453 (CNC more) and figure out what I/O to define.

For a post processor, I recommend you search the duet forum via Google search. “Duet3d cnc fusion360 post processor”

There should be one or two options to test. I’ve used one successfully in the past but can’t remember which. Without a doubt, you’ll need to either modify the post processor or at least review the generated gcode to remove or add codes that are needed for your specific application.

Also look into the ooznest cnc to see if anyone has a post process for rep rap firmware

@o_lampe ‘s comment about motors is relevant. If you haven’t already, you’ll need to decide on the platform and how the motion will work. Will it use steppers or servos? If steppers, what size? Will they have encoders for feedback? Etc.

But sure, as far as motion control the duet can do it. You’ll just need to define the system details and work out the integration.

Do you have any specific components you’re trying to use in the build?

@HebigT Thanks - I am asking only about postprecessor side and the firmware/GUI.
I am not after hardware side - it is all sorted out. Not the first Rodeo
