Can i use mach3 for dispensing?
« on: November 09, 2009, 08:46:35 AM »
i found this option in winpc-nc software

Can mach3 do the same?  I can use dwell, but specially I need to activate some  output  signal before the line end!!!

very good thread about donming machine, but i`m using gear pumps with stepper-not valves, so i need to inverse my gearpump before the nozzle get to the end of the line, that why i need mach3 to give some signal before the end of the line.

maybe i can modify cam postprocessor to have some gcode but adding m-code have bad effect to lookahed function

for example: i need to travel from x0 to x100 without stopping.
gcode looks like:

g1 x0
g1x50
g1x100

if i add m7 code, for example

g1x0
g1x50
m7
g1x100

movement will be interrupted in x50 point.

tried this too, bus same result-stopping in x50point.
g1x0
g1x50 m7
g1x100
