Ray from C3D suggested dropping a message here as I’ve just ordered a C3D board for my ‘previously upgraded’ K40 that had RAMPS/MARLIN 1.0 installed. Badly. It was upgraded from a Moshi board, which wouldn’t have worked with K40 Whisperer or Lightburn, but it is now utterly incapable of engraving correctly - blame the 8 bit brain I guess, and there are all sorts of issues like laser permanently firing, even in overscan etc that I just don’t know how to deal with. So C3D it is!
In short they’ve soldered directly to headers, which isn’t such a bad thing (although bad normally), as there’s less to rework - they just used flying leads and solder - but I think they’ve ruined the 12 pin ribbon socket…
If anyone could help and tell me how much of a sod I’ve got here - I’m almost temped to bin this machine and get a new one at the moment
Even knowing where/how to get the right 12 pin ribbon cable would be a bonus at the moment!
I have more photos, but can only post 2 as a new user.
