POWER with WEIGHT!
Let me start by saying the upgrade package is amazing, but did not come without some challenges. The 80mm spindle started causing drift in the z axis, resulting in cuts not staying relative to the z axis zero. This may have been an issue for a 1year old highly used CNC and the X stepper was on its way out, not sure. So the Longmill got a full PM. New bearings, new delrins, couplers, the whole PM package. After completing the full PM, the issue was unresolved even after assigning a holding current to the Z stepper. I then upgraded my Z stepper to a nema 23 HI torque stepper that will be installed this weekend to see if the drift goes away. Otherwise I am impressed with the ease of installation and integration with my Longmill MK2
