Gentlemen :

Downloaded and installed a copy of FreeCad today and noted that it has the
capability to generate 2D tool paths . As a result of this , it does pass
the necessary Gcodes for tool offsets and types in the G28 G29 codes .
Haven't seen any minkowski codes yet but this is what I am looking for .
(Just learnning this stuff guys so bear with me please ) I have a
micro-controller circuit designed and breaqdboarded to do the necessay
coding for a Diamond Head extruder AND the 'pulses per mm. of fiber extruded
divider network' . The divider uses a simple algorithm which divides each
color extruder by the amount of active colors at the time being printed .
This division would allow for the COMBINED extruded of all active ones to
TOTAL the amount of plastic deposited by a single color head alone . Example
: For a single extruder thru a .4mm nozzle , lets pick a number like 24
pulses per mm moved . If 2 colors are being printed at the same time , each
color head would have its pulse train divided by 2 to get the same amount of
combined material or 12 pulses per mm each . If 3 colors are being printed ,
each extruder motor would be divided by 3 for each head ; or 8 pulses per mm
each .

The hardware is easy for this engineer . Software / Firmware is not as much
. Trying to wrap my head around PYTHON which is what FreeCad is coded in .
Lotsa homework to do to get to the color handling and Gcode interpreter
routines . HELP ! Thanx for the input fellas .
