I’m trying to get some firmware going for my modified CR-10S.

I’ve added a Chimera set up, so I have a second hot end, thermister, extruder, etc. I’m tweaking the TH3D firmware, though I could use stock Marlin? I’m not finding the following settings in Configuration.h.

Looking for advice on the following:

  1. Now I’m adding a second extruder - is there an easy way to enable it?

  2. I added a Geeetech BLtouch, and it seems to work. Do I use EZAble? I can put in my own custom x,y offsets. Control is on Pin 11, signal/power is on +Z end stop (NOT -Z, that’s still the limit switch). I guess I need to tell it to use that pin?

  3. Lastly, the two extruders differ (“titan” and OEM Creality), can I set steps/mm different between them?
