Hi, Alan
Check the following:
- do you have the latest version of Mach4 and PoKeys plugins?
- open the Diagnostic > PoKeys plugin and observe the status boxes for limit inputs. Are there any green boxes (activated switch)?
- switch to Machine diagnostics tab and observe the I/O statuses. Is there any switch marked as activated?
- did you enable Pendant option in the wizard when adding the device? If yes, open the pendant settings, scroll to the bottom of the list and check the status in the 'G' column for the 'Emergency switch'. Does this field have the green background? If yes, check the 'Inv' option for that line.
Regarding the E-stop connection - this is copy-paste from the manual (available at
http://www.poscope.com/PoKeys57CNC):
Note: E-stop switch can be connected either to dedicated E-stop connector (red 4-pin connector) or
to pendant connector (a combination of both is also allowed since both are wired in series).
a) E-stop switch is connected to dedicated 4-pin E-stop connector between pins 2 and 3.
Jumper 'NeST' must be removed and inserted into the pendant connector between pins 4
and 6
b) E-stop switch is connected to pendant connector (between pins 4 and 6). Jumper 'NeST' must
be present
c) Two E-stop switches are connected - one to dedicated 4-pin E-stop connector (betwen pins 2
and 3) and one to pendant connector (between pins 4 and 6).
