Solder heated bed connection during build?
Hi all, anticipating the arrival of my kit over the next couple of days. Been reading a lot of incidents with burnt out bed connectors. Is the consensus that it's better to just solder them from the beginning, rather than leaving it then soldering if it actually does decide to melt down?
I'm sure I read somewhere on here that the Prusa built machines are soldered - can anyone confirm this - or did I imagine that part?
I can solder in my sleep, so I'm not concerned about that aspect.
Thanks 🙂

I would build as designed, but pay extra attention to seating the heatbed connector firmly when you build the printer.
My Rambo was originally supplied for a Mk1 printer, and has subsequently been connected(upgraded) to a Mk2 printer, without problem

Thanks Joan. I guess I'm just very aware that this kit is (of course, brilliantly) a solder-free kit. But if soldering such vulnerable connections is superior, someone like myself who is extremely confident with a soldering iron is bound to wonder if the entire thing could just be failure proofed from the outset. I was mostly trying to gauge what others were typically doing tbh.

Step 13 in the build manual:

Sorry, I was a bit vague in my original post - I'm referring to the rambo end - you've probably seen the "crispy/melted" connector posts

In that case, they are not soldered at the RAMBo end.
I have had no trouble so far (few months) and often heat the bed to 120C + .

ok, I'll leave it alone then - first sign of misbehaviour though, out will come the soldering iron ! 🙂
Maybe some have just had bad luck, connector slightly dislodged or something.

One thought is that the cable loom may not be fastened well and allow the connector to work loose...
of course we will never know because faulting probably results in the wiring loom being disturbed anyway...

Belt and braces may be to solder wires onto the board and terminate the other end under the screws on the connector, if there is room, creating a secondary path that would share the current, and still allow dissassembly with out a soldering iron...
