Introduction |
| The ZPrinter 650 3D printer has a large electronics module which controls the operation of all components. Replacement module is very expensive, it cost around 6000 USD in 2015. What is even worse, the original producer (Z Corporation) was bought out by 3D Systems and they stopped providing spare parts for older (pre-2012) printers. However, I figured out the main reason why the electronic modules fail: a small embedded PC mainboard based on VIA C3 processor. Chinese comrades who manufactured the board used cheap CPU fan and when it fails, the CPU will burn out. In one instance, the fan failed after mere 2 months! You can't replace the CPU (it's soldered to the board), but it's possible to buy a new mainboard. It has part number ENDAT-3220M and can be usually found on Ebay. Ocassionally, it also appears in PC surplus stores and the like, just Google for it. Other Z Corporation printers also use this mainboard, Zprinter 450 and Zprinter 250 for example. Unfortunately, it also depends on production year of the printer, so I recommend to disassemble the printer and check the actual mainboard type before you buy. | | | WARNING!
