Just blown 5 times 20A fuse on Replicape and don’t know what is wrong 
I have 24V/500W power supply. Last time i was testing if everything is ready on printer. Had heatbed (450W/24V) connected directly to replicape (together with 4x motors 1,7A run on 0,85A). For testing everything separately it was ok and i forgot to connect heatbed through SSR so i blow a fuse on replicape. Till today i was searching for new fuses. Last fuse was blown today when i had connected only power cables to replicape when i switched power on (nothing else connected to power supply or replicape).
If you’re blowing fuses with nothing hooked up, you’ve probably fried and shorted something. Maybe the heatbed FET.
Original fuse on replicape was also 20A. I connected heatbed directly only for test of heatbed. When i switched only heatbed on, through replicape, it was working. Afterwards when i got SolidStateRelay i forgot to rewire it. During test i realized i need better heatbed (it took me more than 20mins to heat up to 100°C), something like 800W/220V or more will be better.
Nothing looks like that is fried. How can i check if something is shorted out?
You need an SSR or coil with that heated bed…
