ISR frequency * time significantly below 100%		01/01/70 00:00
Not sure, whether I got you...		01/01/70 00:00
That is not the main problem		01/01/70 00:00

Long ISRs are no problem, unless...		01/01/70 00:00

ISR is set to 1ms but...		01/01/70 00:00
That is the problem		01/01/70 00:00

What is the baud rate?		01/01/70 00:00

Who tells your micro how the stepper is to be moved?		01/01/70 00:00
reply		01/01/70 00:00
So, the stepper is running all the time?		01/01/70 00:00
ya...this is the purpose of having interrupt		01/01/70 00:00
Ok, then confirm this please...		01/01/70 00:00

Still delays in the ISR?		01/01/70 00:00
reply per		01/01/70 00:00
I suspect that your ISR is longer than 1msec!		01/01/70 00:00

ISR code		01/01/70 00:00
Post full ISR		01/01/70 00:00

Still not full ISR shown - and debounce?		01/01/70 00:00
