Hello there
while setting to axis position i accidentally crashed the tool into the rotating chuck
for some reason the emergency stop button didnt function when i hit it.
I did an emergency stop by switching th machine off at its power switch
after replacing the tool tip I started the resetting home and the
axis DRO's but to my surprise ther arrow keys on the keyboard ( I am using a
flexible keyboard) are now functioning erratically ( sometimes wont jog in a direction until
i jog in a different direction- then it will jog again)
Is there any possibility that the program has became corrupted due to a "spike"
when i had the stoppage?
I thought that maybe the keyboard malfunctioned - but it does the same thing with
a different keyboard?
I am going to reinstall mach3 and try again
Has anyone had a similar problem or can anyone offer a comment??
there was a message on the diags screen-but i dont remember what it said something about
"reinitialization" or "reinitialized"
best regards fred

is it happening on just one axis or all

It is only the arrow to jog the x axis towards negative

if its an open loop stepper based system then it cannot be the computer as there is no loop back to the computer from the electronics. Mach 3 doesnt know the power was cut.
Is this a smooth stepper based system? Even then there is no loop back, but the reason I ask is that I always use the ESC button on the keyboard for the STOP. I never smack an EStop button. If its a Smooth stepper based system, and you try and use the STOP or Pause buttons in Mach 3 then there is a buffer delay before the machine will stop, but the ESC should stop it instantly. The ESC is located in a convenient place and I have been running them so long that its muscle memory to reach over and smack the crap out of the top right of the keyboard :)

In my opinion you should have an E-Stop and that E-Stop should be a hardware E-Stop and not rely on Software.The E-Stop can also inform Mach of the situation but should be foremost a hardware one.
