Hi Caleb,

I understand one point of confusion.  The motor/motorApp/AcsSrc contains files for 2 different drivers:

These files are for the old model 1 driver.
-rw-rw-r-- 1 epics domain users   669 Oct 16  2015 drvMCB4B.h
-rw-rw-r-- 1 epics domain users  9427 Oct 16  2015 devMCB4B.cc
-rw-r--r-- 1 epics domain users 16068 Jan 21 18:27 drvMCB4B.cc

These files are for the new model 3 driver.
-rw-rw-r-- 1 epics domain users  1611 Oct 16  2015 MCB4BDriver.h
-rw-rw-r-- 1 epics domain users 11797 Oct 16  2015 MCB4BDriver.cpp

Your startup script contains these 2 commands:

MCB4BCreateController("MCB4B1", "L0", 4, 100, 5000)
MCB4BSetup(1, 10)
MCB4BConfig(0, "L0")

The first command is OK, that configures the new model 3 controller with 4 axes.

The next 2 commands should be removed from your startup script, they are for the old model 1 driver.

> epics> asynReport 10 L0

That is not the output I wanted to see,  That is a report on the underlying drvAsynSerial port, not the MCB4B motor controller port.  Please send the output of this command:

asynReport 10 MCB4B1

Also send the output of

dbpr Enge:m1 10

and the contents of motor.substitutions.mcb4b

Mark

Please send the following:

- Complete output when the IOC boots and runs for 10 seconds or so after iocInit.

- Output of the command
  asynReport 10 myPort
where myPort is the name you assigned to the motor controller port you created.

I have followed the documentation in the motor record to setup the IOC for the MCB-4B controller board. Using the IO traces I can tell that communication with the board is happening (there is a constant polling of position and responses from the board, etc.), but whenever I try to change a value for a motion field I get the following:
