Geeetech A10 Diamond Hot End

thingiverse

This is my first gen diamond hot end conversion for the Geeetech A10. My printer had a GT2560 v3 board, which has two extra slots for stepper drivers. I printed the part on my Anet A8 because the A10 was in pieces while I reverse-engineered it. In addition to the extra motors, driver, extruders and Bowden hardware you will need: 2x 50mm fans 3x M3x10mm bolts 9x M3x15mm bolts 5x M3 nuts 2x M3x65mm threaded rod Note that the thread for the fan bolts is printed into the parts, so nuts are not needed (very hard to get in place anyway) and overtightening will strip the thread out. The BL touch offset is 30.26 to the left and 14.3 to the front when setting Marlin. I think the part cooler needs a new design because I'm currently not 100% happy with the bridging results that I'm getting. I have mine printed in PLA, as this is what I have and what I generally use. There are some other bits that I need to design up alongside a new part cooler, like updated motor mounts and brackets to change the orientation of the PCB on the back. One last thing: the A10 runs on 24v, not 12v. Ensure you have the correct size cartridge if you replace it because the wires are not long enough on the original. Update: I've uploaded a modified motor mount and a new part cooler. The part cooler is still being tested. 11/05/19: I forgot to mention the pinouts for the additional extruders. In Marlin file pins_GT2560_v3.0.h, #define E0_STEP_PIN 46 //physical 38 #define E0_DIR_PIN 44 //physical 40 #define E0_ENABLE_PIN 12 //physical 25 #define E1_STEP_PIN 49 //physical 35 #define E1_DIR_PIN 47 //physical 37 #define E1_ENABLE_PIN 48 //physical 36 #define E2_STEP_PIN 43 //physical 41 #define E2_DIR_PIN 45 //physical 39 #define E2_ENABLE_PIN 41 //physical 51 In configuration.h, you also need to define EXTRUDERS 3 and SINGLENOZZLE. I need to find out how much of an offset the bed needs to be adjusted because I have just noticed that the nozzle is further from the carriage than the original. It may require some other modification to the machine which will be designed or linked at a later date.
