On a side question what kind of bike do you ride. (Your avatar)

Depending on the day, or the reason, either a 2004 Yamaha R1, a 2003 GasGasEC200 or a 1921 Ner-a-Car Model A.

and another error

But just think how much you are learning about HAL debugging.

Debug file information:
Brother_TC-211.hal:246: Pin 'hm2_5i25.0.7i77.0.1.encoder.03.position' does not exist
net spindle-orient-fb hm2_5i25.0.7i77.0.1.encoder.03.position => orient.0.position[/quote]

My fault again. If you look at the other encoders they look like this:
hm2_5i25.0.encoder.00.position

I had forgotten that the encoder modules live on the 5i25 board, and the 7i77 just passes them through.

One thing that can help here is to insert the linein the HAL file temporarily after the loadrt section. That gives you the definitive list of all the HAL pins, but you only see the output if you start LinuxCNC from the command line.

Anyway, the fix here is to change the offending line to
Onwards! We have a good few hours until I need sleep.

Do you know how to access the IRC channel? We can do live support/chat there.

Started checking the machine and I have a reading error in the x axis so far. moved 3 inches (by program) and checked with a size block (+-.0002) and had to move another .050. So from 1 side of the block to the other it was 3.050 reading from the Computer. Is it an encoder issue or ball screw error comp.

I would expect the Brother ballscrews to be excellent. It may be that something is loose or worn. You probably need to check moving in both directions to see if it is backlash or a linear error.
