Hi TPS!
Do you perhaps have a list of which pound variables are occupied or free in MACH3? I would like to read the feeds out of the DROs depending on the material and put these values after the "F" in the G-code. When selecting the variables, I selected the command "SetVar(1234, GetOEMDRO(1203)) in a macro M123, i.e. variable 1234 always reads the feed - that works. But if I write "SetVar(1235,GetOEMDRO(1203)), then the error message comes up: "Cannot do G1 with zero feed!"
I also tried using variables 1233, 1236, 1001, etc. but got the error message every time. When selecting variable 1, it suddenly worked again. There must probably be some variable numbers in use here as well, but I can't find a list of which they are or which variables are still free.
