Hello, I’ve never encountered this error, but you can Google them to get at least some idea what causes them. Some Zprinter service manuals are online, such as this one:
http://infocenter.3dsystems.com/product-...
According to this one, Error 40901 is caused by “This error is failure of the circuit that reads the heater temperature.“ I think they mean the air heater with fan that warms up the build after printing ends. However, the actual temperature sensor can be mounted anywhere in the build area and I don’t know where. It may be in the heater module itself and maybe the sensor itself is fine, but some wires or connectors got loose. You really need someone with expertise in electronics to identify and repair such problem. If you don’t know anyone, your best bet is to call the official Zprinter service in your country.
In any case, replacing the mainboard will NOT fix this.
Hello, I’ve always got ENDAT-3220M boards from Ebay, so unfortunately I don’t know any other sources. These boards were manufactured by various OEMs and many of them are nearly identical. If you find one with identical CPU, northbridge, southbridge and LAN chip, it’s a good chance it will work as a replacement. Try to ask around on some advanced PC hardware forums, for example here:
https://www.eevblog.com/forum/general-co...
It’s a gamble (like I wrote above, the firmware runs on FreeDOS), but it may be worth a shot. Alternatively, you could try to ask 3D Systems if they sell standalone boards. They refused to do that in 2015, but they do list it as a spare part number 22-15725.
In that case your best bet is to replace it with the same board as original. The boards may look similar, but they use completely different northbridge and southbridge chips. The internal printer firmware runs on Freedos, which is not plug-and-play OS, so it may not run properly on a different HW.
A different board? You mean different part number than ENDAT-3220M? Please post its type or photos.
Everyone! Please don’t provide any help or information to Edward Aylward! He is from Noble 3D Printers company which defrauded my employer - we ordered binders for 1000 USD and they never delivered them. And we weren’t the only ones who they cheated:
