I have the PLCM-E3 motion control & PLC4X-G2 breakout board ordered but they will not be with me until march because of Chinese new year. i am using the time to try and get to grips with the electrics / electronics and hopefully start into the MACH 3 (getting to know you period !!) i know some builders on here do not use bleed resistors to drain the caps from the power supply . i was going to leave the drives drain the caps as suggested on various posts but on second thought said i would at least try and get to understand how it done and maybe use a bleed resistor across the n/c contact of the e/ stop relay to keep to good practice and safety as pointed out. i came across this https://www.digikey.com/document-red...calculator.xls i have a result of 1000 ohms over 35 seconds with initial power at 4.9 watts. OR 1710 ohms for 60 seconds with initial power of 2.8 watts. i don't know if these resistors are viable because i've absolutely no prior experience to work from. maybe they will do or perhaps previous builders use a different spec. i have also updated my electrical dwg to reflect my proposed capacitor bleed arrangement. any feedback on this will once again be greatly appreciated.
