Geeetech Adjusted X Endstop Stepper Cover

thingiverse

A stepper cover that adjusts the x-axis end stop approximately 1mm, 2mm, or 3mm farther away from the bed on Geeetech A-series printers works well without risking other parts of the hot end carriage hitting the stepper motor housing. This adjustment gives a small amount of extra space when using a purge bucket (https://www.thingiverse.com/thing:3372835). Make sure to adjust your printer's end stop location so that it can properly home using the newly adjusted endstop location by adjusting X_MIN_POS for Marlin in the firmware, or by using the M206 or M428 commands and saving to EEPROM with M500. The new end-stop location is now at approximately X[-10 - y] where y is the adjustment distance you chose (e.g. if using the New_X_Stop_Adjustment_-2mm.stl, the new end stop location is X[-10 - 2] = X-12). Finally, if using the purge bucket, take advantage of the extra space by changing the bucket's X position in the script ("G1 X-9.5 F600" becomes "G1 X[-9.5 - y] F600"). The included pictures show my machine with the New_X_Stop_Adjustment_-2mm.stl part printed. Others are untested, but should work fine (there appears to be at least another millimeter before the hot end carriage wheel hits the cover, so the -3mm version should work well).
