Hi
I've just built up the hobbycnc 3-axis kit. Driver board is working fine off a bench PSU. I've built up the Psu with capacitor and rectifier supplied in kit and a 300VA transformer (30V,10A). Before I connected it up to the driver board I checked the output voltage and i'm getting 47vDC. I've checked it on a scope and i'm getting no ripple. This seems to be a bit high for the driver board. I've checked the input to the recrifier and it 29.7vAC so the transformer's giving the correct voltage out. Has anyone got any ideas why i'm getting such a high output and can the driver board take it or will it fry the chips?.

Thanks in advance

Matt
