60-70v unregulated power supply recommendations

[Clive S]

I just want to check that the symptoms I'm getting with my set-up is down to an inadequate power supply. Here they are:

• Losing steps on rapid travel
• Drives trip "sensorless stall detection"
• I also get an occasional message from Mach3 saying something like "one or more of the drives exceeded the 25000 kernal setting".

I've got the current settings at maximum.

I believe you are using about 36V smps at present it will be night and day difference on 70V toroidal
