Power Supply for AMS

Hi Dan, I’d been running my drawbot with a re-used 5V, 5A computer supply.
It worked OK, but the motors and drivers got pretty hot and eventually the supply failed.
I borrowed a big metered power supply and did some experiments.
The AMS will take up to 12V, but when the drawbot is running, the supply is always in current limit.
At 2 amps, the voltage is about 4V and the motors and board aren’t too hot and it doesn’t look like the robot drives any (or much) slower.I saw that you ship Makelangelo 2.5.2 with a 12V, 2A wall supply and tried one of those. Interestingly, the couple I tried have overcurrent protection/shutdown, so the gondola makes a few jerks before the supply shuts down.
Did you find special wall supplies with true current limit, or am I confused somehow?
Thanks!
Our makelangelos use 12v2a power supplies for all versions.
AFAIK they are not doing anything interesting.
I’ve never tried to run them with a 5v supply.
