Its low profile, and lack of any protruding shaft from underneath meant it could just sit on the desk while testing. |

| - | As mentioned, I started with Shapespear's [[https://cdn.instructables.com/ORIG/F59/07PC/IJUCSTEF/F5907PCIJUCSTEF.zip|3D scanner firmware]], which was a great base as I had no experience with Arduinos at this point and his code did most of what I wanted. My code is basically the same, but I have removed the manual step-and-take-exposure button function and added a post exposure delay selection option instead. The other minor change is that I don't use the motor enable/disable controls. | + | As mentioned, I started with Shapespear's [[https://cdn.instructables.com/ORIG/F59/07PC/IJUCSTEF/F5907PCIJUCSTEF.zip|3D scanner firmware]], which was a great base as I had no experience with Arduinos at this point and his code did most of what I wanted.

| - | The program has the stepper motor and camera type set within the code, I assume it will be used in a fairly dedicated mode. So it would need to be recompiled and re-downloaded to use it with alternative devices ((the Arduino IDE uses the term "upload" for sending the code to the Arduino board, but in my terminology one downloads from the larger machine to the smaller machine - eg you download from the internet to your PC)). | + | The program has the stepper motor and camera-type set within the code, I assume it will be used in a fairly dedicated mode.

| All these functions except "Up" (cycle through exposure count options) are live, even during a stepping run, so that you can tweak things while a scan is in progress. | All these functions except "Up" (cycle through exposure count options) are live, even during a stepping run, so that you can tweak things while a scan is in progress. | ||
| - | I might update the code so that the manual step options just step one stepper motor step, rather in units of stepsPerRevolution/stepChoices, as that would be more useful for aligning the photographic subject exactly where I want it. | + | I might update the code so that the manual step options are just step one stepper motor step, rather in units of stepsPerRevolution/stepChoices, as that would be more useful for aligning the photographic subject exactly where I want it. |
