Hi, I have integrated the fused layer modeling process into linuxcnc. If desired, I want to integrate the concept in mainline linuxcnc.
I tested the integration with a big 3d printer (1000x1000x1000mm) with linuxcnc 2.5.4 (installed from live cd). The concept works fine. You don't need the beagle bone or raspberry pi for position control. Position control is the job of linuxcnc with standard pc hardware. You need an Arduino, but for temperature control only, because the parallel port don't serve an analoge input. (In addition to this, I use a mesa card for step generation, because I need higher step rates up to 80 kHz. If you have a short 3d printer (e.g. 200x200x200mm), the parallel port is enough. But for my axes, I prefer high velocities ;) ) The integration works with: - bash scripts (to realize the mcodes) - a plc programm (to compare set values and actual values of temperature for enabling - and a userspace HAL component for the communication with the Arduino. The Arduino sketch supports commands in plaintext and contains two temperature controler. One PID for the extruder and another one for a chamber heating unit or alternatively for a heating bed. The userspace HAL component use a state machine to check temperatures and set temperatures. In addition to this, you can communicate with the Arduino via terminal.
