prusaprinters

<p>Hi PP i am posting here my project, i am willing to modify one of my prusa mini to direct drive extruder and more sturdy frame like Bear.<br/> If you want the Haribo version check it here:<br/> <a href="https://www.prusaprinters.org/prints/36631-prusa-mini-mk3s-smokistyle-upgrade-haribo">https://www.prusaprinters.org/prints/36631-prusa-mini-mk3s-smokistyle-upgrade-haribo</a><br/> Soon i will post also all the files list of extra material and the pictures of the printer afterwards.</p> <p>Please note that for using dual-z i will split the z axis connector, i will not change the firmware, also if you did notice the x axis and the extruder are mirrored because we want that minda hits those points during the calibration.<br/> Our farm is getting bigger so we are looking for a workhorse like mk3s, so we will use all our minis to modify them.</p> <p>Original Prusa MINI is a great printer as it comes from Prusa but we will give it a try, this is how we do learn stuff. :D</p> <p>Check for the pictures here :<br/> <a href="https://www.prusaprinters.org/prints/37939-prusa-bear-mk3s-mini-ultra-upgraded">https://www.prusaprinters.org/prints/37939-prusa-bear-mk3s-mini-ultra-upgraded</a></p> <p>Github project here:<br/> <a href="https://github.com/3DPGVA/Prusa-Bear-MK3S-MINI---Ultra-Upgraded-">https://github.com/3DPGVA/Prusa-Bear-MK3S-MINI---Ultra-Upgraded-</a></p> <p>Wiring Z Axis:<br/> <a href="https://github.com/3DPGVA/Split-Z-Axis-for-MINI">https://github.com/3DPGVA/Split-Z-Axis-for-MINI</a></p> <p>Feel free to comment here or in the forum.</p> <p>Cheers</p> <h3>Print instructions</h3><p>Edit1: Uploaded the Fusion360 project. Next I will print the parts to move to the next iteration and i will post the print options I'v used.<br/> Edit2: Good news i will also do a version of this with 3030 extrusion lets see how it gets.<br/> Edit3: Stls Uploaded for the frame, need to modify the extruder body a bit that Minda Hits as in the MINI. Also this part is not Modified take it as it is : <a href="https://github.com/gregsaun/bear_extruder_and_x_axis/blob/master/printed_parts/stl/common_to_all_versions/x_end_idler_tensioner.stl">https://github.com/gregsaun/bear_extruder_and_x_axis/blob/master/printed_parts/stl/common_to_all_versions/x_end_idler_tensioner.stl</a><br/> The rest of the parts are costumized one by one as in the pictures.</p> <p>Forum Thread connecting dual-Z-Axis :<br/> <a href="https://forum.prusaprinters.org/forum/user-mods-octoprint-enclosures-nozzles/buddy-board-dual-z-axis/">https://forum.prusaprinters.org/forum/user-mods-octoprint-enclosures-nozzles/buddy-board-dual-z-axis/</a></p> <p>Soon to the assembly instructions ;)</p>
