CNC controller in PC case , black out proof ?
i bought a dud of a china made CNC , discontinued line ( i wonder why )
it was dam cheep and im proud i bought it ,. could not by the parts for the price they were on ebay
ive had the controll box moving the x,y,z nice and smooth
but the VDF installed was a dud , the mosfit's were not toughing the heat sinks ???? so have to rebox it to fit a new vfd
tonight's effort
since I had an old PC case lying around that was about the volume i need , it got stripped back to bare shell tonight , and a pair of 240 volt 120,mm fans fitted to it , i gutted the blown up power supply ( lightning hit my bore and blew every thing up in my house ) and fitted 3 x solid state relays on a heat sink , a 6pin control plug , power" in" and switch , will have to cut a hole for the second power in ( on same phase , separate 10amp fuse )
the dream
with this build i hope to sort out the power " black out" problem , 2x 240 volt inputs , 1 for the steppers and control side , a separate 240 volt input for the heavy load spindle , cooling pumps and fans , compressor,vacuum pump, ect if the power gos out UPS units will keep the PC and mach3 controll powered for over 3 hours , and switch to pause ,
, once the power comes back on , hit resume ,
in the build up and wet season Darwin will have 3 black outs a day , most for less than 5 sec , but enough to stuff up your job
will also try to shield most high noise items inside the case
