well here is the PSU and e stop circuit . i'm not sure if my calcs. are correct so i could do with a second opinion. i have calculated for 5 motors but i'm only using 4 to get the me up and playing . the 5 motor will be for the A axis further on up the road ( https://www.youtube.com/watch?v=EIwEh6ZmFFs) i have calculated for the lowest cap. and rectifer but will go with something with more head room. any way , feed back would be great , cheers in advance

Paulro That looks fine to me the rectifiers are usually 30 - 50 A anyway. Not sure I would switch the earth out though. ..Clive

Have a search online for the caps make sure they are rated to 100v or higher you might be able to find them cheaper is you buy say 4700uf and then double them up Rapid also does the transformer as well 25 - 0 - 25v and wire the coil in series to make 50V ..Clive
