I would like to run 'raw' curves so need to disable all the acknowledgment's for speed purposes. Where are the examples of this. I know there was a Python implementation in the demo's but I can't seem to find it. Had to do with creating a buffer management system for filling the que, and disabling status routines etc.
Is there a good search term for finding info on using G2 like this?
Is it as simple as setting [si] status interval = 0 ,[sv]=0, and [qv] =0?
Thanks

I can't help with your question, but am curious about your definition of "raw curve".
Would it be correct (or close) to interpret "raw curve" to mean that the Gcode stream will be only G1 commands, generally short x,y moves(or perhaps x,y,z moves for 2.5D or 3D objects), and no G2 or G3 arcs (that need to be processed by tinyG?
Just curious, I have not see that term before
Precisely. Actually I think the term used by cad folks is 'third order curves', where you are drawing lines/curves at high resolution, step by step.
There was a tutorial somewhere I have not been able to find showing the concept. Certainly the curves video demo is doing this.
I believe it was an 'advanced tutorial' written in python that I remember seeing. Where did it go?
Wonderful platform for CNC. The microcontroller based CNC model is a major advancement over the RT-OS/parallel port based approach.
Cheers,
