Wiring:
This is a simple interface to control a stepper-motor via a serial-connection.
The idea is, to send a movement- or setting-command from a remote control-box
(not shown) to the Arduino/Stepper to move it.
I use a cheap 5€ 5V/200mAh/60Ω stepper with 96 steps/rev (3.75° steps), 6 cables (2 common ground);
I have no idea if it's unipolar or bipolar or whatever, so please don't ask. It has very little torque but works very well for this test
I intend to use it to control the x/y-axis on a DIY-3D-Plotter.
| Command: | Result: |
| s### |
change number of steps to ### f.x. s100 sets the motor to do 100 steps on execute |
| d# |
sets the direction of rotation to # valid options are 1 for FORWARD and 2 for BACKWARD everything below 1 is set to 1, everything above 2 is set to 2 |
| m# |
sets the stepper-mode: 1 for single-stepping, 2 for double-stepping 3 for interleave and 4 for microstepping everything below 1 is set to 1, everything above 4 is set to 4 |
| r### |
sets the stepper-speed to ### rpm r96 for 96 rpm (default) r0 sets the rpm to 1, anything below 1 would crash the script you might have to experiment for best settings for your stepper |
| v |
prints out the current settings no additional parameters needed |
| (enter) |
runs the motor with the current settings (no feedback) |
| e |
prints out the current settings and starts the motor (combination of "v" and "") |
| x |
return the stepper to the original position (not yet fully working) |
? |
shows a short help the available commands (this table) |
anything else | is currently being ignored |
Still to come:
* stepper-selection via serial
* serial-control for pen-servo
