I'm re-doing the magnetic engine I first built with the UP Plus 2 , this time I have super sized it to fit the Zortrax build plate . Hopefully it will be completed within a week
this is the old working engine link https://www.youtube.com/watch?v=A2G0-vBT2kc
LOL it's a little stronger than just a solenoid coil , it has 50mm rare earth magnet with a 58kg holding rate on the piston , coil design is also different , it intensifies the magnetic field to the center of the coil not outwardly creating a greater pull force , hahaha in the video when the counter balance wheel flys off , you can see it spin in one place and go across the table , the lead in the counter balance was 800grams alone , that engine also got upto to over 800rpm with a load (small genorator/alternator connected) , My new one is 65% larger using a 76.5mm rare earth magnet with a holding rate 168kg , unfortunately I need to find material strong enougn to hold together ,z-abs broke apart within 5mins under the stress
