I there As some of you know, I use EMC to drive a gluing machine (basically a XYZ router) to put some silicon sealant around photovoltaic panels.
I use EMC 2.4.0~pre from the experimental package here : http://www.linuxcnc.org/experimental/Karmic/ On a Xubuntu 9.10 sytem. I use the spindle-on output to drive my glue valve. I just finished the hardware part, and give a try. One big problem showed up : If for example I do this tu put some glue around a corner : G21 F3000 G54 G0 X0Z0 G0 Z0 M3 S1 G1 X150 G1 Y150 M5 G0 Z0 M2 The result is at the end of movement, M5 take some "long" delay to execute (maybe half a second or like that), witch results in a big glue spot at the end of the line. So I tried this, at the end : (...) G1 Y145 M5 G1 Y150 G0 Z0 but same problem, beacause in this case movement stop at Y145, then the machine waits something, then M5, then the move finish to go Y150. I tried using coolant and mist outputs for driving the valve, the beaviour is exactly the same. So the question is : why this delay, and is there a way to avoid it ? Should I use a M10* code with some ladder or something else to drive my valve ?
