The risk of being an early adopter is having to correct problems, spend money on upgrades, and sometimes to find yourself stuck with a non-upgradable incompatibility. Open hardware/open software products don't really have any such thing as a "non-upgradable incompatibility", which is one reason I like them. Mostly it's a matter of whether or not an upgrade costs more than you want to pay for.innkeeper wrote:i've thought about perhaps getting a single and/or dual v4 head for the m2, but i've thrown a lot of money at the m2 printer fixing or finding issues that existed from the day it was made so i was in no rush to spend more on it. so all i can do for now is relate my experiences with my replicator 1 ..
That's part of what I am aiming for in this modification. I only see a small drawback in using the right extruder only, in that the right extruder can't trigger the X-min endstop, so you would have to connect to the left extruder when homing the X axis, then move all the way to the right to make the right extruder active, then back left to park the left extruder. But that's a fairly quick one-time-only startup maneuver. Alternately, an X-max endstop could be added on the right and everything mirror-imaged, but I think that's more complicated than it's worth.innkeeper wrote:i think the best of both worlds would be if you could easily swap out single and dual extruders depending on your project
