"Failed to get planning buffer" when sending Gcode to TinyG with small steps #77

Description

@bartona

I'm running into a problem where when I send Gcode to a TinyG V9 (Othermill) using ChiliPepper and SPJS, and there are small steps in the Gcode (specifically that of a small arc around the teardrop of a through hold pad), my TinyG just crashes with a "failed to get planning buffer error". When I send the same gcode using another software (CNC.js for example), I don't get the same issue.

Also, is there and documentation on how the tinyg bufferflow options work, and how serial data moves through SPJS at a high level? I was trying to dig into the code to see if I could find a resolution, but it was becoming difficult to follow.
