Is there a way of doing this without having to re-compile emc say by setting some values in an ini file or writing hal code? I havent looked at emc at all except to use it to run my steppers so this is all new to me. > 4 -- I would implement an external function (ExtFn3) that takes the > arguments X and Y and returned the Z value (in variable #999).

I can write the code to read my profiles and output the depth value but can I return this value as a variable in emc? Again I dont know anything about hal. Ive quickly scanned the tutorial and saw that you could set parameter values. But thought that these hal parameters are not the same as the #5000 type variables I could use. Is this correct or am I missing something?
