Bunnie Huang posted teardowns of the [form 1](http://www.bunniestudios.com/blog/?p=3110) and [form 2](http://www.bunniestudios.com/blog/?p=4641). [This picture](http://bunniefoo.com/form1/f1td-galvo-mounts.jpg) shows the form 1 galvo assembly (assuming you have form 1) and the text “20K-0098” is visible on the motor - not sure if it is x- or y-axis. Googling for “20K-0098 galvo” actually returns another thread from the formlabs forum in which another user had similar issues with the y-axis galvo: [swapping out a bad galvo: the PhenixTech PT-20K is a drop-in replacement](http://forum.formlabs.com/t/swapping-out-a-bad-galvo-the-phenixtech-pt-20k-is-a-drop-in-replacement-video-of-tuning/901). Good luck ---

The real problem with replacing the galvo on your own isn’t the process or procedure or even finding a replacement part, though it looks like finding it may be slightly difficult, It is calibrating the machine after the replacement. That can only be done by Formlabs. If you have a Form 1, then you MIGHT be able to mess with the pots to get it close. The Form 1+ is calibrated internally with software ( I believe). Unfortunately, I think you are best off getting a quote for the repair from Formlabs and have them do it. -David ---

@saadahmd You can replace and recalibrate the galvo’s yourself in the **Form1** as per my thread above linked by @100ideas - but not in the **Form1+** or **Form2** - as @DavidRosenfeld mentions the Form1+ is calibrated electronically via a Formlabs designed custom galvo control board. The original **Form1** however used an off the shelf galvo control board (and galvos) which has potentiometers on the board to adjust the galvos. As I say, see my thread linked above on how to make the replacement. ---
