printbus,

I understand. My board is currently running on type 99, I think. Will switching to 33 affect anything else or is it even possible to change specifically the pin for the heat bed? I just ordered a heat bed relay to use D9 and for future use because it seems that I probably should have used one in the first place. I like the 20020109-H061A01LF that gmay3 pointed out, but will I be able to solder a connector to the heater cartridge and heat bed relay safely? Typically for those pins the connectors are attached to a very high gauge wire, like 22 gauge for example. Will the connectors and wires be able to support the level of current going through them?

And will the polyfuse being out of the loop introduce any new possible dangers? Should I enclose the heat bed relay in some sort of plastic enclosure so that in the case of it shorting or this issue happening again the enclosure will melt on it? I'm actually pretty paranoid because of this.
