I am a plastics designer, i.e. I have little electronics experience, pls be nice
I am prototyping some lab equipment which ideally would use a button press to trigger a stepper/leadscrew to send a gantry down (Fwd) to an endstop and then retreat (Rev) to a home position.
Could I use a Tic to do this without an additional micro controller? After going through the guide I would be looking at this set up.
1.Use Fwd and Rev endstops.
2. Set auto homing reverse.
3. Have the Tic in analogue position mode, with the post scaler set very high.
4. Fake an Fwd analogue input with a button.
- Button press triggers analouge position Fwd,
- The gantry hits the Fwd endstop.
- The Gantry then auto homes to the Rev endstop.
This would allow me to control positioning entirely with the endstops, which is within my skillset and will be far easier for the end users to control if adjustment is needed.
Am I bending the Tic to the wrong use here, or is there a better pololu product for this?
Am I understanding the analouge use correctly, or is there a better way to give the system a simple “run fwd a long way” command that does not involve coding?
