* After about 6hrs of printing perfectly, suddenly get a '''large''' x-axis shift again. | |||
* This video '''uses a different driver board''' -- but provides an EXCELLENT way to measure the Ref. Voltage for the driver current. | |||

* This photo proveides info. about the '''G3D Drive Board''' that is used in this printer. | |||

* The REF voltage was upped from 0.5V to 0.64V | |||
** This should correspond to a current increase from 625mA to 800mA | |||

* Spent '''hours''' adjusting the X-axis belts to even get this to print. (Belt not lined up problems, etc..) | |||
* Then spent hours more continuing to make tiny adjustments, to get a print that finally did not have any x-axis shift. | |||
* ATRAIN advised that it seemed like the stepper current needed to be increased. | |||

* Tighten the X-axis Belts yet again. (Really tighten, and use old white glue on/behind washer to prevent slipping.) | |||
* Update the firmware for the final PID values. | |||
// AluHotend E3Dv6 | |||
#define DEFAULT_Kp 8.66 | |||
#define DEFAULT_Ki 1.02 | |||
#define DEFAULT_Kd 48.80 | |||
* NOTE: had to leave this in what I '''hoped''' was working order, as the glue should be left to dry for 24hrs. | |||
