3D scanners are not cheap, and the last thing you want to see after purchase is bad data.But this is [Dave Does] And others were using their Revopoint POP scanner until some public brainstorming discovered the reason: the electric turntable that came with the Kickstarter version of the product was spinning too fast and the software could not accurately track the object. So he decided to replace the stepper motor controller in the turntable And document the process for anyone else who might encounter difficulties with the scanner.
In the video below, [Dave] Open the plastic shell of the turntable, revealing a very sparse interior. If you want to perform some core upgrades, there is a lot of empty space inside, and there are even some mounting studs for tightening new components. But for his purposes, a general stepper motor controller is sufficient. He found a suitable board on the Internet, the price was about $5, and began to design a 3D printed bracket that matched the existing screw holes on the turntable.
But this is not exactly a substitute. On the one hand, you must make a hole in the side of the housing so that the potentiometer knob can stick out. You must also solder the wires from the original DC jack and power switch to the new board to connect them, but at least the motor is plugged in.In the video below, you can see [Dave] Demonstrating the impressive deep throttle capability of the new driver.
If you prefer to build rather than buy, we have introduced some impressive DIY turntables in the past, which can meet the requirements well, from handling camera-controlled automatic models to fully 3D printed versions that you have to do yourself.
