MesaCT and 7i76eu Issues with generated configuration was created by LearningLinuxCNC
It could be that I am an imbecile. However when I used MesaCT as installed per the instructions here using apt  gnipsel.com/linuxcnc/mesact/install.html#install-with-apt . I did not get an anywhere near working configuration out of the tool. The stepper configurations were very incomplete. The feedback loop was not closed in fact the PID output was not even sent to the mesa stepper driver. 

I will post up my configuration files from the output shortly.

Here is a generated HAL file X axis configuration.
Code:
# Axis: X Joint: 0 Output: 2 # PID Setup setp pid.x.Pgain [JOINT_0](P) setp pid.x.Igain [JOINT_0](I) setp pid.x.Dgain [JOINT_0](D) setp pid.x.bias [JOINT_0](BIAS) setp pid.x.FF0 [JOINT_0](FF0) setp pid.x.FF1 [JOINT_0](FF1) setp pid.x.FF2 [JOINT_0](FF2) setp pid.x.deadband [JOINT_0](DEADBAND) setp pid.x.maxoutput [JOINT_0](MAX_OUTPUT) setp pid.x.error-previous-target True # joint-0 enable chain net joint-0-index-enable <=> pid.x.index-enable net joint-0-index-enable <=> joint.0.index-enable net joint-0-enable <= joint.0.amp-enable-out net joint-0-enable => pid.x.enable # position command and feedback net joint-0-pos-cmd <= joint.0.motor-pos-cmd net joint-0-pos-cmd => pid.x.command net joint-0-pos-fb <= hm2_[MESA](BOARD).0.stepgen.00.position-fb net joint-0-pos-fb => joint.0.motor-pos-fb net joint-0-pos-fb => pid.x.feedback # PID Output net joint.0.output <= pid.x.output # Axis: Z Joint: 1 Output: 3

This is what I had to change it to in order to make it work properly.
Code:
# Axis: X Joint: 0 Output: 2 # PID Setup setp pid.x.Pgain [JOINT_0](P) setp pid.x.Igain [JOINT_0](I) setp pid.x.Dgain [JOINT_0](D) setp pid.x.bias [JOINT_0](BIAS) setp pid.x.FF0 [JOINT_0](FF0) setp pid.x.FF1 [JOINT_0](FF1) setp pid.x.FF2 [JOINT_0](FF2) setp pid.x.deadband [JOINT_0](DEADBAND) setp pid.x.maxoutput [JOINT_0](MAX_OUTPUT) setp pid.x.error-previous-target True setp pid.x.maxerror 0.0005 # joint-0 enable chain net joint-0-index-enable <=> pid.x.index-enable net joint-0-index-enable <=> joint.0.index-enable net joint-0-enable <= joint.0.amp-enable-out net joint-0-enable => pid.x.enable net joint-0-enable => hm2_[MESA](BOARD).0.stepgen.02.enable # position command and feedback net joint-0-pos-cmd <= joint.0.motor-pos-cmd net joint-0-pos-cmd => pid.x.command net joint-0-vel-cmd <= joint.0.vel-cmd net joint-0-pos-fb <= hm2_[MESA](BOARD).0.stepgen.02.position-fb net joint-0-pos-fb => joint.0.motor-pos-fb net joint-0-pos-fb => pid.x.feedback # PID Output net joint.0.output <= pid.x.output net joint.0.output => hm2_[MESA](BOARD).0.stepgen.02.velocity-cmd

Can you attach your ini file?

Did you skip Drive 0 and Drive 1?
