Re: PyCNC - first CNC machine controller on pure Python for

Hello! Great news! PyCNC has full 3D printer implementation. Version 1.0.0 is released. Also I made a hardware with RerRap Prusa i3, RAMPSv1.4 board and Raspberry Pi3. Circuit diagram and photos in repo's README.md file - https://github.com/Nikolay-Kha/PyCNC. First 3D model was printed on this video...

Re: PyCNC - first CNC machine controller on pure Python for

PyCNC endstop implementation has different inputs for different channels. And it uses only for initial moving head to the zero position. After that, signals from endstops are totally ignored, because there is no way to use feedback from machine in realtime with this approach. Wow, that's really nea...

Re: PyCNC - first CNC machine controller on pure Python for

Wow, that's really neat. I wonder if that DMA technique could be used for generating other types of arbitrary signals from GPIO pins... It's totally possible to generate any arbitrary digital waveforms. I believe, it's even possible to generate arbitrary analog waveform with pulse-width modulation ...

Re: PyCNC - first CNC machine controller on pure Python for

Now PyCNC is compatible with HDMI monitors. So, PyCNC can be run directly from Raspberry Pi3 with mouse, keyboard and monitor:  https://youtu.be/fFp9MaTRyE4 Also, I purchased a new frame — Chinese implementation of RepRap Prusa i3 in aluminum. Now I’m awaiting for delivery.  As you may see, I’m goin...

PyCNC - first CNC machine controller on pure Python for RPi

Hello! I'd like to present first ever CNC machine controller implementation on pure Python(even without dependencies or any C modules) for ARM based Linux boards. Hardware access layer(HAL) allows to implement support for almost any ARM SoC/CPU with suitable DMA module, but currently it is implement...
