Cura not seeing second extruder


Recommended Posts

Posted · Cura not seeing second extruder

Hi folks. I have a Prusa Mk3 knockoff (HICTOP) printer. I decided to add a second extruder. I modified Mendel source code, and got it working: I can heat and move two separate extruders. All is well there.

I use Cura for slicing and printing. Before I added a second extruder, my printer worked well with Cura's "Prusa i3 Mk2" profile. Now, I'd like to be able to take advantage of my second extruder, but Cura doesn't see it. In printer settings there's dropdown with number of extruders, but it only shows (1) as an option.

I tried adding some other printer with "Dual" in its name, and Cura connects to my printer fine, and shows Extruder 1 temp/target temp, but Extruder 2 info is simply blank.

My question is - is this something I have to fix in firmware (like, info is not being sent to Cura), or is this a Cura issue?
Any suggestions would be helpful.
