the air cut i did looked pretty smooth and balanced.i did not have to change the feed rate in the code .my machine is not set to operate that fast.so it just ran at my maximum settings.I also use small cuttters at times,the smallest
is .0075 ,have not killed one yet,but have killed plenty .03125 playing with differant feed rate for differant materials.the A axis on my machine is 600 steps per degree.the X axis is 3200 steps per inch.in your post you mention your
X axis is 20000 steps per.does that per, mean inch?it might be your X axis is maxing out your A . try reducing your microstepping on X by half.the pulse width is for time balance between driver and computer.you will find it in motor
tuning.when i first set my A axis up the motor would not act properly.the motor was the same as the motor on Z axis .X Y and Z were running well. drove me nuts! so i set the A axis as spindle in ports and pins.then started to play with
pulse width running the motor as a constant speed spindle.the motor smoothed out and acted properly at a pulse width of 9 . my old setting was 5 and i thought my machine was pretty smooth.now it is real smooth.between mach,
my computer and the drivers ,setting my pulse width at 9 runs it the best.if i have to use my backup computer that pulse width has to be set at 3 to do the same thing.
