included with patronage. Part list click here ----------- Springs are back on the menu! 15mm red or yellow springs have been tested and work great, (Bed spring are too weak do not use them) Red spring (medium load), the belt needs to be a bit tighter during install but the stiffness of the spring is technically better.: Amazon red spring (<- tested and working great) Aliexpress red spring Yellow spring (light load). Amazon yellow spring (<- tested and working great) Aliexpress yellow spring (not tested, but likely similar) ----------- Updated Dec 22: - mechanically linked top part have been thickened (too thin on the 688 bearing) Sept 8: Z linear rails support with yellow springs STEP files Sept 7 : Z linear rails support - MGN12H 300mm (I need to clean up the file for a STEP export, coming soon) July 6th: updated motor mount design (functionally the same as before, just looks update ) July 5th motor mount updated to possibly remove motor resonance against the frame with stealthchop disabled (undergoing testing) v2 XZ plate with new tensioner, installed from the front July 4th: tighter tolerance on tensioner (ptfe tube version) added missing items to BOM July 3rd: minor tweak on XZ plates to make spring install easier July 1st: very minor tweak on tensioner added a tensioner with smaller holes when not used with ptfe tubing added BOM xlsx, number and an image June 30: very minor tweak on XZ plates June 29: more minor tweak on the XZ plates updated belt clamp added support for red spring (round3 zip) June 28: tweaked XZ plates for easier spring install, tested 15mmx8mm yellow spring and worked great June 27th: removed the dedicated non spring model plate, the spring plate is now the all in one (it is unchanged so far) added synced z version with 230~235mm rod linking both Z belts slightly better organized STEP file June 26th: added wheel printed spacers minor tweak on the squirrel to print cleaner in either 0.2 or 0.3mm layer height June 25th: XZ plates -> LEFT - XZ rear plate (old one had a hole too small where the eccentric nut go into, but if already printed the hole can be easily enlarged with a sharp tool and work) XZ plates alternative tensioning option without spring, use M4x16 instead, info in txt file inside each subfolder added spring install pictures in third release 8mm diameter lower axle option in sixth release ------------ Make sure the belts are the same length and secure to the belt clamps exactly the same way on both side. motor mount can use 16teeth or 20teeth pulley (going to use 20T for now on my printer) klipper rotation distance will need to be calibrated. Starting point with GT2 20T on the motor is rotation_distance:10 Starting point with GT2 16T on the motor is rotation_distance:8 most of it should be semi-intuitive, but feel free to contact me
