That is AWESOME! I'm super stoked that you got that one going!

I have that idea back to 5~6 years ago. At that time, I couldn't find any digital distance sensor and thinking to design one. I went to talk with an engineer in Parallax, Rosevile in California where is 45min drive from my office. Anyway, long story short. Recently I found the sensor so I teamed up with my buddy Rix who know programming well. So, we split the project in half: hardware and software. I take care the hardware production and he take care the coding. First prototype was terrible because wrong ball screw was using and some design flaw. It cost me a trip back to China and got it fixed. The first version could travel as fast 80mm/s. The revised model can run as fast as 300mm/s.

See a new video I made:

A couple customer called for the status of their purchase of the RTAF system. I'm sorry that we're a little behind schedule on PCB designed and fabrication. The design is completed and has been sent to prototyping. The controller should be ready in 2~3 weeks.

Hi Marco

I’m interested in purchasing one of your new “Real time tracking autofocus laser heads”, for a customer with a very large laser cutting machine, for which leveling of the cutting table would be too hard and expensive, I have a few questions though:

- Does the item in your online store (LSR-RTAF70M) include the stepper motor, stepper driver and power supply?
- Is this head a standalone unit?, does it have its own control independent from the machine’s controller?
- Is it compatible with any type of laser controller? Or is a specific DSP model required?
- Could you please send documentation on how to integrate it to a laser machine?

Thank you in advance for your help
Best regards,
Fernando

Hi Fernando:

Good to hear from you again! Please see my reply below:

- Does the item in your online store (LSR-RTAF70M) include the stepper motor, stepper driver and power supply?
Ans: Motor (Yes), Driver(Yes), power supply (No, you need DC 24V 3A or 5A better)

- Is this head a standalone unit?, does it have its own control independent from the machine’s controller?
Ans: Yes.

- Is it compatible with any type of laser controller? Or is a specific DSP model required?
Ans: Should work for most DSP controller. It need 'LH' (TTL signal to Laser power supply to work)

- Could you please send documentation on how to integrate it to a laser machine?
Ans: Working on it. It is pretty simple for installation and control. The most challenging task is to get it correct mounting plate to hang the laser head. Plus, a modified mounting plate for the 2nd mirror may be required. But we provide laser metal cut to assist you should you provide a drawing.

Hi Marco,

Great!, I'm working as an advisor for a customer who is building an incredibly large laser cutter (around 20 feet long!), he will be purchasing from you, not me, I think it will work, I'll have him contact you when we're finished selecting the required components.

Hi Marco,

Please let me know as soon as you have documentation on how to install this new head, I need at least electrical connections instructions as I need to verify what's needed to interface your head's control to the machine's controller

Thank you
Fernando

Hey Fernando:

Sorry to reply late here. I've been really busy recently. I just received a circuit board for the RTAF laser head and been testing for a while. It is a new design board but it it not in final stage yet. Once I have completed the tested and setup, I'll provide a step by step procedures to assist you folks to install the auto focus system
