So technically these are 2 questions:
First off, for the SSR mounting, my kit didn't come with the M4 threaded spacers but I was wondering if they were indeed necessary or could I just mount it without the spacer with the back heatsink directly on the bottom of the printer (thus the bottom of the printer would be the "heatsink") or should I come up with some kind of innovative spacer mechanism using my existing M4 screws?
Second, for the DSH, does the whole printer package contain both the regular DD as well as the DSH kit? Should I try with the DD first and then DSH later or would that be a nightmare in terms of unmounting/unwiring?
