Hello all,
This is my first post on element14, and it's a challenge I've been facing for months. I have a rebranded Makerbot Replicator 2 which i got from monoprice.com. Supporting documentation is scarce, but the motherboard has another driver slot and ports for a second print tool, so I put one together and installed it. It has the same temp. sensor and hot end electronics as the existing one did and the stepper is the same as well. The fans are the same voltage and I've double and triple checked the connections. With only one tool running everything runs perfectly smooth, but when i try to do a dual extrusion test the first layer will get partway through and the entire printer will shut off then turn back on. It seems like the power supply cannot handle it, or that there is a short, but as I've said the connections seem to be sound. I've read in one other forum that the power supply on this type of printer isn't quite capable of running the extra stepper but i want to be sure before I go tearing apart my printer any further. Any tips or suggestions, or anyone else who has done this? I couldn't seem to find any instances.
Thanks in advance!
