EMC Hal and halui config.

[rockhopper300]

I have a three axis machine that makes paintrollers, the three axis are controlled with stepper motors and GHEKO drives. The setup does not run off G-code but use the jog function to move the three axis at the same linear speeds. I have configd the axis to move forward at 1000mm/min and return at 10 000mm/min. The pins on my breakout bord gives the signals to move, through to the par port to the computer. I set up the hal file to accept forward jog (pin 13 closed) and then reverse on pin 15 closed. With pin 15 I wrote the halui file to accept mux2 together with the reverse command at the higher speed. THE PROBLEM: Sometimes when the axis reverse it does not take the mux2 command.(The axis reverse, but at the lower speed) I switched on the halmeter and the mux2 light does change??? I then used the hal scope to see what the signal looks like, and sometimes it is not a perpendicular line to the trigger amplitude, but rather a 70 to 80 degree line. QUESTION: Can that be the cause that the program sometimes read the command together with mux2, and other times not?
(PS I hope I am on the right forum, if Im not, SORRY)

These lines I added to hal

load or 2
addf or 2.0 servo-thread

loadrt mux2
addf mux2.0 servo-thread
setp mux 2.0. in1 10 000.
setp mux 2.0. in0 1000.

#...setup par port1...
net xjplus <= parport.1.pin15-in-not
net xjneg <= parport.1.pin13-in-not
net yjplus <= parport.1.pin12-in-not
net yjneg <= parport.1.pin11-in-not
net zjplus <= parport.1.pin10-in-not
net zjneg <= parport.0.pin15-in-not


The following lines I wrote in halui.hal

net jspeed mux2.0.out => halui jog-speed
net xjplus halui.jog.0.plus
net xjneg halui.jog.0.minus => or 2.0.in0
net yjplus halui.jog.1.plus
net yjneg halui.jog.1.minus => or 2.0.in0
net sel or 2.0.out => mux 2.0.sel


If any one can help me I will greatly appreciate.

Nota Beni - There is an EMC2 forum just a little ways down where questions like this are more likely to get answered quicker.
