General Mach Discussion / G73 G83 Mach3Turn

« on: March 23, 2009, 05:24:09 AM »

I am trying to drill a 1/2" diameter hole through a 1" Diam. X 3" long piece of barstock using Mach3Turn. The G73 cycle is what I need but have tried all of the suggestions I have found on the forum and they do not work. When I run the program Mach3turn does all of the other lines of code and then skips the G73 and goes on with the rest of the program. I am using G73  Z2.9 Q.1 R.1 F2
When I use G83 it works as it should but does not rapid feed back down the hole to where it left off before returning to feed speed (the return to its last position is at F speed which really slows up the process. Could someone write me  the code using G73 to drill a 2.9" deep hole .100" per peck and retracting .100" prior to going back for the next peck of .100"? Thanks for your help. This is the only thing keeping me from running parts at this point.

General Mach Discussion / Hardinge HNC lathe conversion

« on: March 15, 2009, 09:36:38 PM »

I have been running the CNC lathes and mills in my shop for many years now using Flashcut and Turbocnc V4.01. I am currently trying out Mach3 turn on our HNC lathe and need advice on how to map more than the 6 outputs currently visible on the diagnostics panel. I need the following outputs:  M03 1 output,  M04 1 output,  M07 1 output,  M22 1 output,  M21 1 output, Vertical slide 1 output,  Turret index solenoid 1 output, Turret stop solenoid 1 output.
I know how to write the VB script for activating and deactivating the outputs. This works very well for the 6 outputs that are listed, but how do you map the remaining outputs? How would you write the VB script for output 8  ActivateSignal(output8) and how would you assign a port and pin number to it since the ports and pins dialogue only goes to 6 outputs? Also can you use the enable lines as outputs to control solenoids etc instead of their normal function?
