Interface Posibilities ? was created by arnold.braun
Hello Together,
sorry i´m new.
A simple quesstion.
I want to connect my own mictochip to controll the steppers.
I would like to transmit the postion for x,y,z and not the step -signals.
How can i setup LinuxCNC to do this.
Interface Parallel, USB, Network every way is posible form me.
thanks a lot arnold

While LinuxCNC is designed to be the controller and output the step and direction signals I assume you could hack out part of LinuxCNC to parse the G code file. Download from the Git repository all the files to a user directory then you can look at them a see what you need.

Why not use a linuxcncrsh to control linuxcnc?
Just a small computer with no screen and so on controls the machine with linuxcnc and through the network you gen poll the positions to your controller ans send also commands to the machine.

The Pico, Mesa and Pluto drivers work exactly this way. I suggest having a look at how those work.
Making your chip emulate the Pluto interface might be the easiest way.
git.linuxcnc.org/gitweb?p=linuxcnc.git;a...57a03d8517710572d7e0
The Pluto-step driver also has the advantage that is is a .comp and can be (fairly) easily installed without recompiling LinuxCNC.
