Since I expect much higher rigidity than my current printers and I might want to have a heavier carriage (converting to CNC maybe), I&#8217;m thinking about using NEMA23 motors.\n<p>I have options to go with 1.8 or <a href=\"https:\/\/www.oyostepper.com\/tag-9-09deg.html\">0.9 deg stepper motor<\/a>, I can get 23HS7628 <a href=\"https:\/\/www.oyostepper.com\/tag-4-18deg.html\">1.8 degree stepper motor<\/a> with 18.9Kg.cm holding torque , 23HS5628 1.8\u00b0\/step motors with 12.6Kg.cm holding torque or 23HM1430 0.9\u00b0\/step motors with 18Kg.cm holding torque. I would use TB6600 drivers at max 1\/16 microstepping.<\/p>\n<p>Since motor prices are quite different, I&#8217;m curious to have a second opinion. I think the 0.9\u00b0 will probably not bring any quality improvement since the limitation will still be mecanical, and anyway since the motors are much stronger than nema17 I can go further in useful microstepping. I can get a sweet deal on the 12.6Kg.cm motors, and I&#8217;m hesitating with the 18.9Kg.cm ones (1.8\u00b0) which are 50% more expensive.<\/p>\n<p>Or&#8230; should I just stay with (cheap) Nema17 motors?<\/li>\n<\/ul>\n<p>Any thought?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hi, I&#8217;m about to build my 3rd printer, even though I&#8217;m getting quite some experience already I&#8217;d like to hear some other advices regarding stepper motor.
