M112 cancel command funky #2

Closed stefanix closed 12 years ago

stefanix commented 13 years ago

While the command does work it shows some strange behavior regarding its arguments. For example "M112X0Y0F10000" should stop any processing and move to 0,0 at F10000.

It seems to move it to 0,0 plus an offset and at whatever speed was current.

M112 response highly improved in norcham branch, still a bit slow in some situations, eg. very long, highly tesselated, gcode programs that bring the controller to its speed limits

This got fixed with the ! and ~ control characters and when the code base got aggressively simplified. The main issues where data cross-access from main thread and stepper interrupt. The solution was to simply request certain things and let the part of code that was mainly responsible for a certain data field do the adjustments/deletions/etc.
