I have read of the documentation as I can and looked through all the Tech bulletins but I haven't found information on how to set up the control to work with dual handwheels in the way that a Romi Easypath does. Do I need to modify the PLC program, I have looked through the PLC manual and did not stumble across any handwheel macros.

Yes, it requires a custom PLC. In the mpuplcprograms/lathe/ALLIN1DC directory on the install program, there should be a "DualHandWheel_JoyStickJog" directory. Try that PLC program as a start.

I don't know if the OAK PLCs have been updated with the handwheel code, but it's easy enough to merge the handwheel code from the AllIn1DC program into the Oak Standard Dual Joystick program. The PLC program comments will tell you what encoder and input connections you need.

Thanks I'll check into that

Most standard lathe PLC programs should already have dual handwheel support. Browse through the "MPGStage" section and review the comments.

In short:
1) Connect your handwheel encoders to any two available encoder inputs
2) Set those encoder input numbers in parameters 348 and 351
3) Set the desired "clicks" (dial units) per revolution in parameters 349 and 352
4) Set the encoder counts (4x the line count) in parameters 350 and 353

Here is an example Allin1DC basic lathe PLC program that supports dual handwheels and a joystick, as well as the wireless MPG and VCP.

Thanks I'll take a look at the files in this report
