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

Ok back home and debugging again

and another error

Debug file information:

and line 246

net spindle-orient-fb hm2_5i25.0.7i77.0.1.encoder.03.position => orient.0.position




no idea on the fix

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 line in 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.

Just got back in wifey draged me away to do errands

No on the trc channel , but I will look it up. This time linux starteds all the way then ended quickly

Debug file information:
Brother_TC-211.hal:247: Pin 'pid.spindle.command' was already linked to signal 'spindle-orient-pos'

and a little lost.
do I just delete the line ???

I think I made it there

Thanks again to andy and pete for there help on irc to get my orientation all taken care of. 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 only moved the machine in 1 direction btw.


Also What pins do I look at to tune my servo's correctly.

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.

I'm pretty sure it is a linear problem. I only Moved in the x pos direction during the check. I also found an error in the z axis of. Apex. .015 all in the z minus direction. I haven't done any back lash checks yet. I was wondering if it could be a metric ball screw or I have the encoder counts wrong

How about error over distance, is it constant? how much error over 1", 2" 5", etc. i.e. maybe the encoders are 2048ppr rather than 2000ppr. Or, more complicated here, the encoder connections are not physically wired how the cards are reading them or visa-versa.
