Let&#8217;s keep going. Today is March 18th, 2014. Just over a year behind.<link rel=\"image_src\" href=\"\/reprapblog\/wp-content\/uploads\/2014\/03\/IMG_2105-1024x768.jpg\"\/>\n<p>So I was working on the child RepRap that MY RepRap had built, so I could give it to the Museum of Science. During the last post I&#8217;d done its first print and the traditional minimug toast. Now I had to get the endstops working.<\/p>\n<p>This was my first Prusa Mendel (IT2) build, so I didn&#8217;t know how the endstops would go on (in the original Sells Mendel the optical endstop mounts were all integrated into the build, but on the Prusa Mendel you have a lot of &#8220;flexibility&#8221;). I decided that I still wanted to use opto-endstops (vs mechanical ones), but that made it more difficult to figure out where the endstop flags should go (and I don&#8217;t like the idea of using glue for anything).<\/p>\n<p>For the Z axis, I wanted to design a small opto-flag holder for Z (adapted from the endstop holder for Z). I set up the opto-endstop in a helping hands aligator clip to help measure what the piece should look like, and put the original z-endstop-holder (that I was adapting) on the X axis:<\/p>\n<p><a

Budaschnozzle mount and the extruder is at <I>exactly<\/I> the right height for an opto endstop board mounted on a standard Prusa IT2 endstop holder.<\/p>\n<p>I modeled them with paper then cut them out of tin after (I say &#8220;them&#8221; because not only did I put the X endflag beneath the left of the extruder, but I put another shim of metal beneath the right of the extruder so it was evenly balanced).<\/p>\n<p><iframe loading=\"lazy\" width=\"640\" height=\"360\" src=\"\/\/www.youtube.com\/embed\/hSuvx_iQxk4\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n<p><a
