Hi,
We installed a handwheel and 2 rotary knobs to control a 3 axis milling machine (see picture). The first knob is used to determine the step of each click of the handwheel (1x, 10x, 100x) and the second one is used to determine wich one of the axis has to move (X,Y,Z,A). The only way I found to control the step of each click is by changing the ACCEL, DECEL and RAPIDSPEED parameters. Here's the code placed in ~@~INPUTIO.FIL for moving the X axis:

IF #63=1 THENIF #64=1 THEN ACCEL 1;10 : DECEL 1;10 :RAPIDSPEED 1000: HANDWHEEL 1;4000;OK2STOP1 '1x

IF #63=1 THENIF #65=1 THEN ACCEL 1;100 : DECEL 1;100 :RAPIDSPEED 5000: HANDWHEEL 1;400;OK2STOP1 '10x

IF #63=1 THENIF #66=1 THEN ACCEL 1;1000 : DECEL 1;1000 :RAPIDSPEED 10000: HANDWHEEL 1;100;OK2STOP1 '100x

IF #63=1 THENIF #67=1 THEN ACCEL 1;1000000 : DECEL 1;1000000 :RAPIDSPEED 120000 :HANDWHEEL 1;400;TACH 'Dyn

And here is my jog button macro:
Code placed in ~@~INPUTIO.FIL is:
IF #34=1 THENIF #62=1 THEN [Jog Buttons X+]

Code placed in ~@~MACRO.FIL is:
[[Jog Buttons X+]]
WAITUNTIL STOP
HANDWHEEL 0
IF#34=1 THEN FEEDRATE 180 :ACCEL 1;120000 : DECEL 1;120000: POSITION 1;9999: WAITUNTIL #34=0
IF#34=0 THEN STOP 1:EXIT

[[Jog Buttons X-]]
WAITUNTIL STOP
HANDWHEEL 0
IF#35=1 THEN FEEDRATE 180 :ACCEL 1;120000 : DECEL 1;120000: POSITION 1;-9999: WAITUNTIL #35=0
IF#35=0 THEN STOP 1:EXIT


I have 3 major problems using these commands:

1- Each click of handle doesn't move the machine of the same step (see graph). So how can I set the handwheel so one click moves the axis of exactly one increment (0.0001", 0.001" and 0.01") depending on the knob position?

2- Each click through the negative direction moves the axis of about twice the distance it moves through the positive direction (see the graph). How can I set the handwheel so each click in any direction moves the axis of the same distance?

3- Using the handwheel seems to desactivates the jog buttons. Any ideas where that could come from?


Thanks a lot in advance!
