Twotrees laser TTS-55 and adding limit switches

I purchased a Twotrees TTS-55 laser to add engravings to my projects. I do need to say that I purchased this laser with my own money, it was not given to me by Twotrees 3D. I also added limits switches to the laser. After assembling the laser and adding limit switches I feel that this laser is a good small format engraver for hobby projects. I look forward to many projects with this laser.

Thanks for the great video! And the links!

Cracking laser and mine on its way as a new business venture, worth you investing in the air assist will give you even cleaner work and cuts. Grreat video 👊👍👌

Quick tip: if you flip your motherboard upside down on the front you will have the clearance to center longer pieces under the frame.

The expansion is available as part of the unit or separately currently

Спасибо тебе, друг! Благодаря тебе сделал концевики на свой гравер!

do you happen to know if they work on a TTS 10pro?

Great video. Do you know how to install switches on the other 2 ends? as a protection to not grind the motors in case it tries to run off the limits? than you.

I just received one ( my first ) and it’s a huge learning curve for me, I’m not sure if I like Lightburn or GBRN better ? But mine has the air assist that does make a difference in cutting . I’m not sure if making it larger is better but I deal with small engravings on leather and ceramics and aluminum.

Nice video, just need to confirm the orientation of the wires 😁 so based on the video, its red(voltage) on top, black (ground) in the middle then green (signal) at the bottom? Thanks!

What are the connector types on the board? I have PH2.0, but those aren't correct.

Question about limit switches, I have several on my laser but didn’t know how the actually work. Is the laser head supposed to physically hit it? Or is there a sensor on the limit switch that senses when the laserhead comes near it? I ask because my laser head Rams in the mind sometimes and wants to keep on going and I have to shut the machine off quickly.

Hello everyone.
I added limit switches on my TTS-55 pro, and I noticed after that I have a lot of USB disconnexion during jobs, after 2/3 minutes.
I tried a 22 minutes job after disconnecting the switches, and it runned smoothly to the end.
Anyone knows what the problem can be ?
BTW, the problem occurs on Lightburn. I didn't test with another soft.

I have had requests for the feet I used to secure the laser to plywood, so I added the stl files to Thingiverse, same link as the limit switches.

[guythejedi]

where is the link for the feet you made?

Diode lasers are the worst, they don't even cut white paper.
