Need Help!- Ajax Mach 3 can't fast jog ??

[ajkmp]

Just installed my Ajax kit. Got past most of the hurdles (limit switches, motor tuning/directioin, etc.)
Problem:
1) I can't fast jog to save my life. (settings:fast jog speed 100, slow jog speed 10)
2) Can on toggle between incremental and continuous with the onscreen jog pendant.
3) Shift and arrow key no response.
4) Do I need to do something special for this?? And/ also is there a method to use the Reference ALL to home instead of typing M92 p#??

Anyone. . . Anyone

Ctrl-J turns off jogging.

I can toggle jogging.
Slow jog works fine.
Just can't fast jog.
My limits/homing seem fine as well(motor direction, jogs off w/ M92 p#, etc.)

Ant ideas???
Thanks in advance.

You can use "Reference All". In Mach select "Operator" -> "Edit button script" -> click on the "Ref All' button when flashing, remove the exisiting code and insert: (copy and paste only the text in bold)

code "M92 P1 Q2 R3"

Which says to move the X, Y & Z axes simultaneously to the positive limits and then home at the index pulse. You can modify the P1 Q2 R3 to suit the direction and axes you wish to home.
You may also want to consider splitting the homing into two commands instead:

Home the Z first to make sure it's clear:
code "m92 P3"
sleep 100
While IsMoving()
sleep 100
Wend
sleep 1000

Then home the X & Y:
code "m92 P1 Q2"

Then save and exit.

Here is a Brain that will enable fast jogging when holding the shift key.

http://www.ajaxcnc.com/ajaxbb/download/file.php?id=210

Copy this to your c:\mach3\brains directory and then enable the Brain in Mach by selecting "Operator"->"Brain Control"->"Reload All Brains"->
select fast_jog.brn then check the "Enabled" box ->"Reload All Brains"
