Pokeys57cnc v1.2 sometime means that Emergeny Button is pressed
but i didnt have one and the in the Pulse engine the emergency is inverted
befor i have no problems
nothing else is changed
any idea or workaround
-
Is it Possible to dongrade firmware to see if this is the problem ?

Hi,
you say that you don't have an Estop? That's pretty bold, its about the ONLY input that has to be there.
Have you assigned a pin for an Estop? If you have then may I suggest terminating it with a low value resistor,
say 400 ohms, to either earth or logic high so that the Estop is not active. My thinking goes that if a pin is unconnected
noise impulses may cause the signal to go active.

no i dint need it by now
al works great and i only milling wood
the pin inputs are standard setup
400 ohn to ground ?
-
Hi,
depends on whether you've set Estop as Active High or Active Low. 400 Ohm to earth will be fine for Active High.
I can't help but think you should hook up an Estop switch, so if your machine goes crazy or your Gcode is faulty you can switch it off real quick. In most
countries an Estop is a legal safety requirement. You may have seen the switches, big red button in a yellow surround and the button latches down, hit it
and the machine stops.

but sorry for my missunderstand
if i have no e-stop switch it is the same as when the switch is open
my problem is thaht pokeys meas i press the estop and that is not
´must the estop switch close the connection between pin 4-6 and when i press it it cut the connection or the other way
-
Hi,
I'm guessing that because you have no switch that noise is getting onto the pin and telling Mach to Estop. I suggest loading the pin so that it is less susceptible
to noise.

Hi,
try unchecking the watchdog timers.
Craig

watchdogs are not checked

Sounds like power saving features on your PC.
Check that nothing on your PC goes to sleep or into low power mode etc.

all disabled
