Steve,
I finally restored my wobbly wood gantry routing machine (24" X 48" X 4") to
semi-functional operation. I have been debugging it this eve. I made the
changes to my board as described on the CNCzone forum. This involved
removing 3 components (r-c circuits) out of each axis and connecting them to
an empty pullup pin on the board. (Pin 01).
I have all three axis' wired to the same pull-up pin
I am not using the stepconf mainly because it does not appear to work for
me. I have a working stepper configuration and would like to stick with
that until I have more time to play with the setups.
The config is a marked up stepper_in.ini file I modified. I am using (i
believe) the standard pinout.hal file as well.
Based on what you are saying, I think I would simply insert a line
# Amp enable section
net motor-enables axis.0.amp-enable-out parport.0.pin-01-out
Since my X axis is the most active (and Z the least) using the X axis as a
amp enable should always keep the Z axis ready (yes?).
When I added this line, I could not get EMC to run. EMC is on an isolated
machine ATM and I don't have a thumb drive available to download the error
report. When I comment out the line, the configuration runs normal.
Any thoughts?
Brian
