GT MK8 Auto level for Prusa i3 Pro B and Pro C or Mk8 setup

thingiverse

My First 3D Printer Practicle part that anyone can use if they have an MK8 extruder. I have designed it to fit on the fan for a MK8 extruder and the fan on a Pro C dual extruder bracket which i will show next after i add a second extruder to my Pro B. This part can be installed on a Geeetch single extruder Prusa i3 Pro, Pro B, and Pro C Dual extruder with minor adjustments, some minor changes to certain firmware setups. check out my YouTube channel for the videos i did on this. My user name is: georgeroblesjr i will post my firmware on my wordpress page at georgeroblesjr.wordpress.com I will sell these or the parts you need on my online store if people ask for it. If you want to buy a printer from me and want great tech support, check out my online store: georges3dprinters.comhttps://youtu.be/IcuFkOzr-5khttps://youtu.be/WtjIAIQPWlc Instructions You will need 3-10mm x 6mm cylinder N52 magnets that you can order online, 2-M3 x 16mm screws, 1-M3 x 12mm screw, 1-M3 flat washer, and a push button switch of some sort like off an old TV remote or can buy one new for less then a $1.00. First push in magnets in the two spots they fit in. Remove the screws that hold on the cooling fan to the MK8 extruder (I did this one scew at a time so it would not come apart) and feed the scerws through the MK8 mounting bracket and replace the scews and parts as before. Next take the push button switch and solder on two wires to the two leads of the switch. These wires will be attached to the z min stop replacing the z axis min switch. make sure to remove any obstrutions from the orignal z end stop, like removing the screw which actuates it. In my case, it's on the x axis motor bracket and I had to just get it high enough that it was out the way. Take Z probe arm with the slot closest to you, with the holes on the side closest to the edge on the bottom, take 1-M3 x 16mm screw and thread it through the furthest hole from the right going through the arm to the other side till when you see the threads come out. Then take the second M3 x 16mm screw and thread it in the hole closest to you from the left going through the arm to the other side till about 2mm of thread are showing. Next with the M3 flat washer on the M3 x 12mm screw, feed it through the the arm pivot point (piece with the slot for switch), mount with the holes on the side closest to the edge towards the MK8 mounting bracket and thread it in at the upper center raised screw mount. Lastly, take the third magnet and place on the head of the screw closest to the switch. At this point assembly is done and now you just have to adjust the screws, firmware, and type up some g-code to make it work. see what i did on my youtube channel, my user name is georgeroblesjr, and check out what i did to make mine work.
