That is indeed.. how i decided to brand it and this seems working. In reality both systems have different optical properties; this does matter if you push them to the limits.
Galvanometers are slow, require more calibration. Rotating devices don't stand still at the end of a sweep and are much faster (10 times).
- sydd 7y agothe concept is really cool, congrats! Can the prototype actually print? Do you have some photos of the printed stuff?
- hexa_storm 7y agoThis is how it prints on UV paper, https://cdn.hackaday.io/images/1013221548797737200.jpg https://cdn.hackaday.io/images/1013221548797737200.jpg . This is the calibration data recorded by imaging with the camera directly on a CMOS chip. You can count pixels.. this is what an expert needs to determine the quality. https://cdn.hackaday.io/files/21933938381472/calib_data.zip https://cdn.hackaday.io/files/21933938381472/calib_data.zip More data is here https://cdn.hackaday.io/files/21933938381472/21measurements.rar https://cdn.hackaday.io/files/21933938381472/21measurements.... pixel 4.65 microns. You can use opencv to do the trick. I added a little script in this one.
- thawkins 7y agoGalvanometer based systems often suffer from acceleration issues at the start and end of the swing which limits the usable spread.
