webbing cutter/stepper motor tester
in november 2020 i was asked to make a firmware for a webbing cutter to make dog leashes. the frame of the machine was never finished but the controller firmware works as intended.
it has a 16x2 character lcd screen and a 4x4 matrix keypad.
you can set the strip length & number of strips to cut, and save up to four different programs to eeprom.
if all four programs are loaded, the controller will do all jobs in sequence.
the keys # and * are used to confirm and delete respectively, and the keys A, B, C, D are used to select programs
it uses a stepper motor to move the strip forward and a 5v servo plus a limit switch to cut the strip with a hot wire
later on i was requested to modify the code to a stepper motor tester. this later version changes the strips/length settings to distance, feedrate, acceleration, and direction.
