Beating on this some more on my end; I think I’m seeing a combination of mac related serial port shenanigans and some plotter quirks:
- Inkscape on Windows works fine, Inkscape on Mac chokes after a few lines. I’m using the ‘Plot’ extension, with HPGL selected.
- Control from the terminal not working from either. I swear I could do an IN;PD;PU; and at least get some life out of it a few weeks ago. It reports ‘Cutting’ whenever it receives characters. None of the Output Instructions report anything.
- I have been using a null modem adapter. When working w/ Inkscape in Win10, it seems to be pretty tolerant of various flow control settings. When it doesn’t work in Mac or via the terminal, changing the flow control has no effect. I assumed RTS/CTS was a safe bet, and It’s always set to 9600 8N1.
- The plotter has both serial & USB inputs - the USB is just an FTDI adapter. They both behave the same.
So this is seeming like an issue not related to Rhino. I wish I could see what Inkscape is sending; I’m tempted to lug my VT-100 terminal up here watch the output.
Sorry for the tail chasing, but I’m gonna keep banging on this.
thanks!
