construction of my scanner

Postby Kbbr » Mon Jul 18, 2011 1:26 am

Hi David-Fans!

I am now starting with the construction of my scanner for planeless scanning with turntable and a tiltable frame. The circuit draft for this project I have already improved with the great help of Walter ().

In this topic I want to document step by step the work on my scanner hardware and ask my questions if problems or obscurities appear. At the moment I am drawing the layout for the setup of the electronic components on a perfboard. When it is finished, I will upload it here. Unfortunately the first obscurity appeared already:

Is it a problem if the Pololu stepper motor driver is supplied with power without a connected motor? (VMOT und GND connected, all 4 motor coils disconnected)?

Thanks!
Stefan

Stefan, it's no problem if the outputs are free. But don't connect or disconnect the two motor coils if the Pololu is supplied with power. This could damage the Pololu (or any other driver) in ms for ever!

Walter

PS. I am curious to see your progress.
