Injection molding

Can linuxcnc used as controller for hydraulic injection molding machine ?
For example to read thermocouples and do pid temperature control
actuate hydraulic solenoids read linear scales encoders and pressure sensors.
Does anyone have done retrofit of injection molding machine with linuxcnc ?
A machine that is not gcode controlled and not have linear axes..

A picture and a description of the scope and size of the machine would be helpful.

Hydraulic machines can be very powerful, be careful!

There's an example of an electronic gearbox for a lathe, no gcode, just a custom GUI and some HAL connections.

Probably not a lot that you can use, but an example of what you can do.

My guess would be as long as you can get the data into linuxcnc and output any control values based on the input you should be fine. This would probably require some custom HAL written components to operate on the data and apply the output required. Oh yeah and maybe a gui.

The absolute simplest example I can think of is the parallel port tester, doesn't have any kinematics, but does allow you to control outputs and read the state of inputs.

Just throwing this out there.
MRO is another example. Maybe this could be a starting point, just start be reading data and displaying it, once you have that nailed, you could start with some simple HAL components to manipulate your data.

Not an exact implementation but kind a simple example of what is achievable.

No doubt Andy will have a better idea and contradict everything Ive said, as he's way way more knowledgeable.

The machine is the same model as this

Entry level regular PLCs are not all that expensive as well.

Linux CNC has Classic ladder to do PLC logic.

It might be easier to have a separate, dedicated, thermostat-like device for the temperature.

Simple on-off stuff does not need the "brains" of a pc.

You can use a regular thermostat if you somehow "fudge" the sensor impendance.

Perhaps someone has adapted QtDragon for this purpose or something.
