Dual extruder printer, from the earlier days of printing. This is a Makerbot Replicator clone, which served me well. Not a ton of hours on it (low hundreds), as it was a spare I purchased after running several for years. Happy to walk someone thru the "quirks" of this. Box of spare parts, to include a new dual head, a spare Mega board, cables, leadscrews, etc. Currently needs some TLC to be back printing amazingly, but has been a solid printer.
