Hi,
Thank you very much for your feedback. We understand that electrical schematics can be difficult to follow, especially without an engineering background.
We have now prepared an updated and more detailed documentation file for you. You can review it together with the following video, which may also help you better understand the wiring diagrams: https://www.youtube.com/watch?v=pB56zBjUsFI
We hope the combination of the video and the new file will make the wiring and control system much easier to follow.
Wendy will also send you a follow-up email with the detailed files tomorrow. Please kindly keep an eye on your inbox and make sure to check messages from Wendy@sflaser.net.
If you have any further questions while working on your DIY project, please feel free to contact us anytime. We are always happy to help.
