; Quick motor testing
M913 X35 Y35 ; drop motor current
M564 S0 H0 ; allow movement without being homed and allow movement outside limits
M291 R"Test X axis" P"Slowly test movement of X axis with small increment of movement" S3 X1
M291 R"Test Y axis" P"Slowly test movement of Y axis with small increment of movement" S3 Y1
M400
M913 X85 Y85 ; return motor currents to normal
M564 S1 H1 ; restrict movement of unhomed axis and prevent movement outside limits
If motors still move correctly, test homing.
