hi, i am new in emc2 and still reading manuals.
what i am trying to do is controlling the cnc drilling stations with emc2. the machine has x and y axis with stepper driver step/dir config, Z axis has hydrolic cylinder controller. with limit switchs hydrolic valfes activated up and down. i need to stay xy coordinate till the z come back home(up). so where do ihave to write this delay instructions?
what is the easy way to configure this machine?
thanks

You can write a custom M function which will start/stop hydrolic valfes and check the limit switches.

See M100-199 from the wiki for more info.

Will "Exact Path" mode in gcode fix this?

THat way a gcode string such as

G61
G00 Z0.5
G00 X2.0 Y2.0

The third line will not execute until the Z position is reached.

i think M66 solve this problem. both delay and input wait can be used.
"Exact Path" mode in gcode may be altenate.
thanks for all Acemi and Brian
