Hi i was asked last year to develop a HPGL Ardunio project but the original client has backed out, he does not require it anymore he tells me. Does anyone else want HPGL Ardunio / Raspberry Pi + GertDunio set-up? Raspberry Pi has the Ethernet & HDMI already. Gert sits on-top of this baby giving me access to PWM & I/O for limit switches etc. Plus you can run Linux on the Raspberry with Ardunio IDE. Still under development. Yes i like others never re-invent the wheel so using others work to base on, with custom tweaks for hardware & functionality. I don't know if this project is worth following myself as no one seems to be after HPGL apart from 2D cutters. I think i will concentrate on G-code as it is more professional and is 3D already. interconnect.me.uk Providing bespoke software engineering solutions for CNC & embedded kit.
