Geeetech A10 Direct Drive (2019 Version)michjael.p.

A direct drive upgrade for my A10 <B>2019 Version</B>, based on the Speed Drive for the Ender 3 by Sashalex007 at Thingiverse.com and Marlin 2.0.x build - I have moved to Klipper / Octoprint. I liked the idea of keeping the mass in the center of the X carriage, and looking at a lot of other direct drive upgrades had the motor to one side or the other. The Ender 3 has a smaller X carriage than the A10 so I designed one in Fusion. The small electronics board is mounted on top of the extruder motor. I am using the Petsfang cooling duct with the E3dV6 clone hotend, for the A30 but works well on the A10. Definitely recommend X https://www.thingiverse.com/thing:3192987 and Y https://www.thingiverse.com/thing:3631951 axis belt tensioners. Direct drive spool adapter https://www.thingiverse.com/thing:4023383 UPDATE: 11/05/20 I modded the above Spool adapter to fit the A10's Spool Bracket. I was using Vertabreakers Marlin 2.0.x build - I have moved to Klipper / Octoprint Vertabreakers Discord: https://discord.gg/9q24GaX Vertabreakers Thingiverse: https://www.thingiverse.com/Vertabreaker/about Vertabreakers Github: https://github.com/Vertabreak/Marlin/tree/bugfix-2.0.x Linear advance calibration: https://marlinfw.org/tools/lin_advance/k-factor.html The pictured calibration cube was printed at 60mm/s and 1500 acceleration. Further Thoughts - A pancake motor should fit in this design and give you back almost the whole bed to print on. <b>**EDIT**</b> I have had a few requests for BMG compatible extruder, so I made one! I also made a version without the mount points on top as the earlier version of the A10 doesn't have an elec board. Theres also 2 versions with a cable chain adapter on top as well, one is https://www.thingiverse.com/thing:1001858 and I modified it to fit without hitting the uprights of the machine. <b>Update #1 for 18/05/20</b> I have installed Ubuntu 18.04 dual-boot on an old laptop and got Octoprint and Klipper running on it. All I can say is wow so far, the sound coming from the stepper's is very different! Quieter and smoother. Im in the process of calibrating pressure advance right now but the initial results printing @ 100mm/s and 1500 acceleration are pretty nice! Configuring Klipper was fun too, as a few of the pin maps in the default gt-2560.cfg file were off. It is nice to be able to change the settings in the printer without having to re-flash the firmware every time. I have also added the klipper config file for the A10 in the files section. I have also installed the yellow bed springs and dual bearing V-wheels on the bed. <b>UPDATE 19/05/20</b> Just found this little gem https://blog.notexpectedyet.com/manual-mesh-levelling-with-klipper/ If you dont have a probe like me and were relying on mesh leveling, this is perfect! <b>IMPORTANT UPDATE 23/05/20 HOT!</b> I found today that the X carriage bracket I had designed was not letting the extruder motor cool properly and was slightly melted!! The motor felt REALY hot, not enough to burn but too hot to leave a finger on for much time. I have re-designed the initial version with some cooling vents now AND it has been moved to the right 3.5mm to line up with the hot end properly. Printing it now and will update when its done. New File is A10 Direct Drive Cooling Moved.stl <b>Update!</b> I have been told that the new A10 has a different X carriage and this mod doesn't fit so that's something to be aware of if your considering using this mod. I have also added a fan cooler to the back of the extruder motor to keep it cool, just a 40mm from ebay and plugged into the spare fan point on the small elec board. (have added pics) the STL is the nema_17_fan_mount_SKINNY
