I don't think that there is any need to start again, but you do need to understand why your current config isn't working.
There are four basic things to know about HAL.
1) The net statement is "net signal pin" or "net signal pin pin" or as man pins as you need.
2) All pins connected to the same signal will have the same numeric value and you can use the same signal name on as many lines in the HAL file as you need to, and in multiple HAL files.
3) Each signal can only have one "output" pin which writes the value to the signal
4) You can use any name you want for a signal, but pin names are fixed by the software.
Your problems at the moment come from trying to connect spindle.0.on and or2.2.out to the same signal. But both of those are output pins.
And, also. spindle.0.on is already being used as an input to the or2 chain, isn't it?
If you rewind a bit, you probably just need to change some _signal_ names in my HAL snippet to match the ones in your actual HAL file.
