Vacuum Pump isnt working and cannot figure out why

[E G]

Hello, 

I am trying to run openpnp on my charmhigh t48, and right now everything is working but the vacuum pump. I took the vacuum pump out and tested it, and its working fine. So it seems like the controller board isnt doing its job when I use the M808/M809 commands to activate the pump. Has anyone else ran into this issue? I checked the voltages when using the commands and nothing changes.

check mosfets that drives the pump..

Hi!
M808/M809 are G-Code commands. The meaning and function of this
commands is part the controller configuration. Did you checked, that you
configured them to control the vacuum?
If you're using one of the smoothieware branches for the original
control board, this G-Codes are likely correct. However, there are
differences in the function of the IO. Some configurations drive the
pump as digital others using PWM. This is reflected in the setup of the
actuator. Some use "boolean" and others "double". Depending on the type,
you'll have to provide a ACTUATOR_BOOLEAN_COMMAND or
ACTUATOR_DOUBLE_COMMAND. Internally, the vacuum is operated as digital,
hence one has to provide values for ON and OFF if the actuators is of
double type.
I'd suggest to try the commands itself on the console (Machine Setup ->
Driver -> GCodeAsyncDriver (likely) -> Console) and check what happens.
"M808 S50" shall switch the pump on if configured as digital or set it
to 50% duty cycle if configured as PWM and you're using any of the
smoothieware branch. Then you can check the logs to see what command is
generated if you try operate the vacuum manually.
