im looking for some inspiration on some design layout for my power supply and break brd layout,,,
Does any know of some good links here cnc zone for a clean small really thought out compact design.
Here's one that's worth a look.
(Not sure if you have to be a member of the forum to view pictures.)

Hi eloid,
Attached you'll find three photos of the electrical box for my small machine. Three G210's, 45V powersupply, 24V auxiallry powersupply, opto-isolators for limits and homeswitches and a F/V converter for the spindle VFD. There's more stuff in there than initially planned so it's a bit crowded - works good though so I rarely need to mess with it.
I've also attached a photo of my current project, it's a lot larger project and is still work in progress. 3 HP-UHU drives, 130V 4kVA powersupply with softstart and regenerative powerdump, 5.5kW VFD, C11 breakoutboard and Smoothstepper. I still have a few small things to do on this one before mounting it in the cabinet and closing the cable conduits.
your new control panel is intense...
I too am planing on using the smooth stepper and the same break brd...
do you have a schematic to share, Im still new to the hobby and its my frist
machine,,,, not 100% clear how to wire estop circuit and limit switchs
can you post it or let me know i send you my email address
Hi,
The system is quite complex with a PLC comunicating with Mach3, an encoder-interface between the encoders and SS so that the SS keeps track of position even during E-stop, soft-start, regenerative powerdump and so on. The schematic is over 20 pages at this time and I still haven't finished the home and limit switches...
How to wire the E-stop and what to do depends on what kind of machine you have. Generally you want the E-stop to cut power to the machine. You should NOT rely on the software for E-stop control, you should hardwire the E-stop switch, generally thru a relay or contactor so it cuts power to the machine. Then you can use a second contact to "inform" Mach3 that you have E-stoped.
