I made a post this in the experimental software forum before I realized this forum was here.
One challenge we are currently facing is we are not sure how multiple extruders can be controlled using ReplicatorG.
Our plan was to use one extruder controller to control the thermoplastic extruder that everyone is familiar with, and a second extruder controller to control a head that lays down wire. Hence, we would be taking advantage of the existing firmware of the extruder controller.
However, after much searching, we still could not find information on how this is done, even though the ReplicatorG website states, "more codes exist now for controlling build platform temperature, case temperature, a second extruder, and for controlling stepper motors on extruders." (http://replicat.org/mcodes)
If anyone has tried to program two extruder controllers connected to a single motherboard, it would be awesome if you could let us know how you did it.
We will post updates on this problem here.
Thanks.
