lance-greene 7 Posted April 19, 2016 in is there a guide to choosing proper replacement stepper motors? (edited) so the x axis stepper motor on my machine failed and i need a new one, the only canadian ultimaker supplier is out of stock and i found other suppliers with stepper motors but i have no idea how to determine what will work as a replacement or not. my friend gave me a stepper motor from one of his delta printers but i have no idea how to tell if it is the proper motor or not. it has the same sized faceplate (nema 17 i believe) but the body of the motor is also a bit longer than the ultimaker motor here is a photo of the stepper motor he gave me.

neotko 1,354 Posted April 19, 2016 in is there a guide to choosing proper replacement stepper motors? I only see two problems. It looks larger than um2 x/y stepper so might hit the bed. And the shafts isn't round. There's must be a reasonwhy ultimaker doesn't use marked x/y motors there but only on the feeder? The amps, force and 1.8 degrees seem ok. Worse case you break something Pololu steppers are cheap, but if you buy them otherplace than ultimaker distributor you will need to solder the propper plastic plug to connect it.

lance-greene 7 Posted April 19, 2016 in is there a guide to choosing proper replacement stepper motors? the motor ended up not fitting properly, is there a list of info i need to know about the stepper motor in order to buy the right one from a company that makes them, cause there are some in canada and the distributor here is out of stock for a few weeks and I really need it as soon as possible.

nilrog 92 Posted April 19, 2016 in is there a guide to choosing proper replacement stepper motors? You can find some of the information in Ultimaker's GitHub. Here is a link to the PDF where you can see the dimensions at least: https://github.com/Ultimaker/Ultimaker2/blob/master/1182_X%2CY_Motor_(x2)/B1182-B2P-A.pdf But it doesn't show any electrical details, or what brand/model they actually used. You could also check this clone...it probably uses a stepper with similar characteristics as the original one: http://www.thingiverse.com/thing:811271 He seems to use this one: http://www.robotdigg.com/product/7/NEMA17-Stepper-Motor-40mm-Long,-1.2A Share this post Link to post Share on other sites
neotko 1,354 Posted April 19, 2016 in is there a guide to choosing proper replacement stepper motors? Also if you use that large one, you can remove the bed white thing since on um2 it's just a cover from dust. On github there's a um2 assembly manual that you can check to reverse the installation and take it out. (i suppose) Share this post Link to post Share on other sites
ultiarjan 1,076 Posted April 19, 2016 in is there a guide to choosing proper replacement stepper motors? If your in a hurry, did you check Ultimaker's US manufacturing partner? no idea if they ship to Canada at a reasonable price though... http://fbrc8.com/ Share this post Link to post Share on other sites
lance-greene 7 Posted April 26, 2016 in is there a guide to choosing proper replacement stepper motors? actually i found the best deal is a website called http://www.robokits.co.nz/ they had them cheaper than anywhere even with shipping included. ultimakers canadian distributor had to order them from a warehouse which takes 2 or 3 weeks plus then shipping to me all while costing more than this UK company to bring it to canada Share this post Link to post Share on other sites
