Hey guys, Recently, the Part Store changed the 12v power supply to a Meanwell 12v/29A model. The new power supply is ultra low profile and high efficiency. We think you will really like it. The Nema Stepper Motors have also been updated to include braided wiring. This will make your builds wiring look super industrial - neat & clean! We love them! And since we are talking stepper motors, if you missed it, we now carry the DQ542MA Stepper Motor Driver. As always, we are here to help support your builds with the best quality hardware. There are a few NEW products coming out that I can't wait to share with you! Thanks for your support!
