CR-10 S5 rebuilded to Prusa XXL style 500x500x500 mm printer

prusaprinters

<p>I had my Creality CR 10S5 printer in mostly original state for 2 years. I was printing with it, but I have some prusa printers mk3s and after some experiences I could see so many problems with those Creality printer. I decided to do not mod it, but rebuild it fully. Only frame PSU, MOSFET and motors I used to this new project.<br/> Project goals:<br/> adopted from prusa:<br/> original mk3s rambo board with excellent prusa firmware and tmc 2130 silent drivers (modified firmware, of course)<br/> whole mk3s extruder body with direct drive, filament sensor, and SuperPINDA probe<br/> magnetic bed sticker with steel sheet and textured PEI printing surface<br/> 24V PSU with panic sensor for interrupted power and printing recovery<br/> I left original PSU for bed heating. I insulated whole low surface of bed and I increase voltage of PSU to 12,00 V so heating of bed is faster. My maximum I am using is 75°C anyway.<br/> For Z axis I am using synchronized belt system ang gear box, so strep/mm is the same as mk3s has with threaded rods.<br/> I used synchronized belts system for Y axis too, so no twisting of the bed at all. Gear ratio is 1:2 so Y motor has 2x more torque output for such large bed.<br/> BOM is not ready<br/> Firmware allow me to make homing and bed leveling. Printing not yet tested, but in a few days I will print something.<br/> I need to update movement intervals, so most of the calibration processes from firmware will be running.<br/> Firmware is on github:<br/> <a href="https://github.com/rosch8/Prusa_mk3s_firmware_for-CR10S5_rebuilded">https://github.com/rosch8/Prusa\_mk3s\_firmware\_for-CR10S5\_rebuilded</a></p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>I3 MK3S</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>200</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>30%</p></div><br/> <strong>Filament:</strong><br/> any PETG <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>mostly 3 perimeters.<br/> Orientation of many models is not good, please reorient it before slicing, so you do not need any support.</p> </div></p></p></p></p> Category: 3D Printers
