is classic china basically a part designed by a diy or engineer who looks to be really capable and quite intelligent and designed for one process and china just takes it and makes it exactly the same carbon copy and they do the the easy innovation it's not an innovation just they just printed it with an sls machine and you know say it's better and they should have redesigned but they don't think about these things in china they just make they just as quickly as they can get the product onto the market so this needed to be redesigned the moment that somebody thought that they were going to make it with a different type of NUMBER_TOKENd printing process so yeah lightweight as this is i think i could drop NUMBER_TOKEN not exaggerating NUMBER_TOKEN of the weight off of it by um designing it for selective laser sintering uh and also designing it to include an integrated mount for a hot end but as i've said in previous videos the weight savings in the plastic extruder portion here is kind of uh you know a lot less important than the potential weight savings in redesigning stepper motors so this stepper motor here we've seen it before on the orbiter extruder and it is a lot smaller and lighter weight than a pancake pancake stepper nema NUMBER_TOKEN. still i'm seeing the same um spacing on the screws see diagonal to diagonal it's the same on both of these the shafts appear to be the same and if i hold the circular portion up to the pancake it looks like this could already be just a lightened version of a pancake stepper motor so i want to take a look inside of this and compare it to a pancake but first let's do a weight comparison i'm going to do my best to just sort of hold the the wires in the air i don't really want to measure the wires so yeah i'm not you know moving that but it's not moving very much so we're looking at about NUMBER_TOKEN grams with this one we have NUMBER_TOKEN grams so yeah like a NUMBER_TOKEN gram weight savings pretty impressive but that weight savings comes at a cost looking at the stator for these two motors we can see the nema NUMBER_TOKEN is a lot more robust the windings here using a much finer gauge of wire then this one i'm going to assume about the same number of wirings more windings equals more magnetic power but yeah it's a massive trade off there because the longer the wire in other words more windings equals a longer wire the longer the wire the more resistance which means the more heat so your smaller wire gets hotter as you apply more power to it so you can't overclock this thing you can't just shove more electrons through it to get it to to have more torque whereas with the nema NUMBER_TOKEN here you can absolutely feed more current into it and achieve more torque taking a look at the two rotors here we can see just how much larger the nema NUMBER_TOKEN is it's it's significant right and that means that there's more leverage the magnets are farther away from the center point of rotation so each step is going to have more pulling force so the nema NUMBER_TOKEN is going to be significantly more powerful and speaking of integrated solutions you can see i've removed the uh the stator here completely from the housing and i've got the back housing along with these two screws
