    Sorry, the pitch was of course correct! Thanks for having me double check, I dont think I've realized unless until the build was finished!

    About building the enclosure into lower frame with aluminium plates is a good idea. I have a large 2mm aluminium sheet lying around that I could use. For the next step I will lay out the electrical components in 3D and make a wiring diagram to ensure I have accounted for everything.

    I've seen that atleast both DMM and Sunfar recommends either mains filter or both mains filter and line reactor for the mains power supply. I have seen people here using line filters but I haven't come across anyone using line reactors yet. Is that really as necessary as the manufacturers are claiming it to be?

    Also mounting the electrical enclosure directly to the frame (made of aluminium) would it be a problem since it would basically be in direct contact with the machine frame? I mean that would be a direct earth connection for the enclosure. I am not too into electronics (yet)!

    Thanks everyone for your good and helpful advice!

    No. That will be fine just make sure that all grounds go to one star point. If the frame is painted I would make a direct connection from the box to the frame.

    I would at least fit a mains filter because of them being Servo's, however, I have seen that some people have had issues with DMM servo's because they didn't use line reactors so you might want to fit them to be safe, or just go with mains filter and if you get any issues you can always slip a line reactor in between.!
    It mostly depends on your incoming supply quality I think and I seem to remember those who have had issues where US based which works on different Freq and voltage to EU.

    Regards the frame then yes it's fine and you would want the earth to the frame anyway for safety just in case a wire shorted to the frame.
    -use common sense, if you lack it, there is no software to help that.

    Thanks both of you! This helps a ton. A line reactor costs about 100€, so not a big deal. I will fit one just to be sure!
