Topic: da vinci extruder stepper

Hi,

I'm thinking about converting my Da vinci 1.0 to Bowden style extruder following the design in thingiverse. I wane however keep my options open so I'd prefer to get another stepper motor for the bowden extruder. Can someone suggest a stepper motor that would work (ebay link?).

I am pretty sure the motors used are Nema 17s. Another post said that that were 1.8 degree nema 17 stepper motors. You may need to get some connectors because I am pretty sure the connectors on the Davinci's are added by XYZ.

All the motors on the Da Vinci are standard nema 17. You will most likely have to cut off and save the connector on the existing motor and splice the wires from the motor to the harness. The motor with a connector like they use is a bit harder to find unless you live in China.

Well I managed to figure that out as well. The only thing I'am little bit worried about (maybe without a good reason?) is matching the current. I did some googling and it seems that the Minebea stepper currently in the machine is rated for 1A. If I buy something like Nema 17 that is rated for lets say 1.68A, will it still work with the stock stepper driver?

Yes it will. The current rating is just the max current you can feed the motor without damage to it. It is not the required current.
