Today he made a small adapter for this lens. Now it fits tightly into the other adapter. The focus can be adjusted. I removed his first expansion lens, because I glued the one from the other lens and I don't want to remove it. The two outer lenses are his. They are glued. It works quite well...

I have several blue lasers over 7W with a P4000 driver, which works with two batteries, however. There is no problem with them. And I modify these myself by changing resistors. They have a smooth start. The bad thing is that you have to put them between the radiator.

I found them on another site. There are 17mm and 22mm. I guess they are the same https://convoylight.com/products/detail/15207616 https://convoylight.com/products/17mm-6v-5a-boost-driver

Can you provide a link to the driver you are using?

Today I made a focus adapter. I will be able to use it with other lasers. It turned out very well and is very stable. Really good focus at 40-50 centimeters. With adjustment it can burn things at 3-4 meters. It's not much, but I managed to create this from the lenses I have on hand. I have many...

Today I connected the 120W laser. I didn't have a Secret key and I made a bridge on the plus in order to be able to disconnect the connection so that it doesn't turn on unintentionally when I'm not using it. I'll have to put a metal plate in the front part, because when trying with lenses it...

The cooling will be active of course. There is no danger of overheating for me, because I always put a temperature sensor with a display and see how many degrees. In this case, I always use the lasers for short cycles. 10-20 seconds there is no danger of overheating.

These are the same but have an amperage adjustment option https://a.aliexpress.com/_EGEFm0c

Yes, I know. I can adjust it to this high amperage using the copper wire, like in the video above. But I will use the 1800W boost driver. It is up to 22-23 amps. The power supply will be from two packs of 6 26650/5000mha batteries connected in parallel. Because the BMS I have outputs 40A. With...

@RedCowboy I looked at these, but I don't need them at the moment. https://a.aliexpress.com/_EwsI2Nm

Today I also bought this 500W Raycus pump. The $200 offer was just worth it. With this pump, the filament is removed very easily. Here is a video. I will use the same driver, which is up to 22 amps. There are some step-down drivers that are 30 and 50 amps, but I will need a battery with about...

Today I also made the 12V battery with 9 18650 batteries. I put 16 AWG silicone cables on the BMS output. Do you think they are thick enough for the 15V and 15A load?

Today I got this box. In it I will make the 120W laser which will be powered by 9 18650 batteries at 12V. I will use this converter which outputs 15V and 15A. It does very well in the tests. I am still waiting for the BMS for the other 260W laser. The 120W one will become quite compact. I hope...

I also set the step-down driver for the 120W laser. The battery is 24V, and the driver works at 16V/15A. This is a protective glass glued with glue on the front. This way the laser is sealed. However, it heats up very quickly because it is small and has no cooling. The good thing about this...
