Downdraft design questions

I cant see the difference between vertical and horizontal using passive coling or with heatsink drivers if you haver proper space between the drivers to air flow.
In my mind the question is how hot they get to install whatever the position just pay attention to the heatsink side and proper space to air flow
My motors i follow the manufacture instructions i dont runt it over 80C (68C).
Some drivers are din mount so you cant install horizontal or some models have fan and you need to pay attention to air flow direction.
I have yasukawa sigma driver (servo) and its up mounting and i think its because have fan up side.
I dont know the driver spec here but i guess its the same the oriental about orientation and looks like he have 40mm to 50mm between the driver

I decided to rearrange the driver boards now.

Neat !

Thanks! I just got the motors moving! I need to land the home switches and do some calibration... then I will have to 'hit the books' on Plasmac.

I will clean up the wiring a bit more after I get everything working.

I am not sure exactly when I should integrate the pneumatic actuator solenoids, should that be done before I get into Plasmac, or after?

Motor wires seem very thin, that will limit the torque and speed by quite a margin.
4X0.75 is the absolute minimum for small Nema17 motors that i use, for anything bigger i use 4x2.5mm2.

Interesting. These motors came prewired from the vendor of my previous electronics package. I just checked, these motors are wired with 18AWG, you would use 14AWG? What wire type/make do you use? Thx
