How I move around my heavy DIY CNC

[A_Camera]

BTW, yes, my control box is definitely over-engineered, but as I said, I had no switch for the high current and I like to use what I have when it is possible, so I had to use relays. In fact, I am using four relays, two for one side two for the other, because the relays I have can't handle all that current (around 12A) so I use two relays for one side and two for the other. The 12A is just a guess, but my PSU to the acuators is a 12V 8A PSU which is OK for now, but if I stop the motion half way in the lifting process then the PSU stalls and the actuators won't continue the pushing. The rated current is 3A for each, but I haven't measured what is the current needed to start with load. Anyway, on my to do list is the replacement of the PSU with a 12V 82A version. Yes, eighty two amps. Once again, it is over-engineering, but I have many PSUs like these:



So I will use one of them.
