Did the re-fetch and it just got worse. Now it wont load at all.
First problem was simple to solve even for my little brain and after refetch IPTABLES got root permissions for some reason, I have changed it and the result is in attached report.

Could anyone share his HAL section for a pwmgen on Pin1 on the PP to run a spindle?

I have a setup with one of those chinese "PWM to 0-10V" modules.

edit:got it.

Yes, the outputs are isolated switches (0 to 36V, 0 to 2A)

So you can use 5V or 12V or 24V or anything between 0 and 36V

Note that the outputs are not protected against shorted loads
so use a fused or current limited supply. Also the switches
are polarized (if you connect them backwards they will appear
to be always on)

I should add, you can use an Ohmmeter to test the outputs.
 
Could it be that the ssr´s are on/closed when starting the board?
I think i saw a thread some where how to change it, but i can´t find it anymore.

The outputs are off at startup, though if you wire them
backwards (reverse polarity) they will appear to be stuck-on.
