having fun!! i found that my end nuts on my lead screws had all started coming loose. i also found that my love joy couplers started getting loose. so i fixed that and tuned the gantry a bit to have better bearing contact. i also stretched the bend out of the y axis with a few more turns. im starting to slowly ramp up the speed to see what will work. im at 65 ipm. What is the norm for most of you?
