The MK2 has a great feature that will help ensure great prints every time but you will have to get things set up first. Setting up and positioning your Pinda probe is where all the magic happens or where all the headaches begin. Follow along and with this one simple trick you can put all the troubles behind you and start down the road to great prints.
Once your Probe is in position after running the Auto Home function from the led controller loosen the lock not on the pinda probe and lower the probe down so it touches the dime.
Once your probe has been lowered, secure the lock nut again to make sure the pinda probe is secure in place. Do not over tighten the lock not on the pinda probe or you can break the mount loose from the carriage.
The goal here is for the probe to be almost the same distance from the hotbed as the nozzle. It must be just a touch higher than the nozzle but not much higher. The Probe should he up just enough higher than the nozzle so it clears any curled plastics when printing to avoid collision but not so high that it can not read the sensors in the bed. A dime is just about the perfect distance.
Note: It is important to always run a xyz calibration each time you move the pinda probe to avoid nozzle colissions with your hotbed causing damage to the bed and PEI sheet. After each xyz calibration always run the Calibration GCODE and fine tune your live z so the settings are saved on your controller in the Rambo.
The below is as outlined by the recommendation from the MK2 Assembly instructions. And in the photo at the bottom are the results when using the Dime method as outlined in this article.
