g76 code or g33

I am trying to get my machine to thread, this code should be fine right?
t1 m6
g43
s300 m3
g0z1x.2
g4p3
g76 p.05 z-.5 i-.075 j.008 k.045 h3 r2.0 q29.5 e.05 l2
g0x.5
g0z0
m5
m30


My machine will get to the pause, and when it gets to the g76 line it acts like it's in a loop. I get no motion at all. Same thing on a g33. My commanded speed and my actual speed differ quite a bit on the AXIS gui. Are they too far apart to sync the two axis to the spindle? Any idea where to go from here? Thanks

My code should work though right? I have a rotary encoder connected to a 7i47 board. If i watch the raw counts in the hal meter, it counts consistently at 4096. What am I missing? Thanks

a few things to check
the encoder gives you both an index and an A Pulse ( A & I ) and that the encoder count type is set to 1
it could also be that the encoder input requires inverting

you need to set the commanded speed and actuial speed as close as possible for the sync to work correctly , so scale the spindle so as to get the required result , you should be able to get spindle speed and commanded speed and the speed shown in axis to be within
10 - 20 rpm with care

I am new to this, how do I check the A and index? If I do need to invert it, where do I change that parameter. I am not in front of the machine to play around. Thanks for your help.

I have attached the portion of my hal file that deals with spindle. I am not seeing anything with a " near scaling" statement. Does anything stand out to anybody? Thanks for the help.
