The delivery took 23 days. The laser works fine, however, my previous laser died from overheating and I decided to check this one. The laser module is fixed to external aluminium anodized casing with three M2.5x4 flathead hex screws. The screws are tightened nicely, but there's no thermal paste between contacting surfaces, even though they're pretty flat. Laser diodes are mounted (most likely press fitted) into a machined aluminium block that goes into a U-shaped aluminium radiator and is additionally fixed with five M2.5x4 standard hex screws. There is thermal paste between contacting sufraces, but it's not enough since one side of the machined block barely has traces of the thermal paste. The laser driver is a typical DC-DC step-down regulator with current feedback loop. I ordered a 24V version, but PCB silkscreen says 12V on a power supply pin and (which is more important) electrolytic capacitors on the PCB are rated only 25V, and one of them is connected to both ground and power supply pin. For a robust 24V application you would need capacitors rated at least 35V. The PCB placement between the fan and the laser module is controversial. On the one hand, it is cooled directly by the fan, on the other hand, the laser module is cooled through a slot milled in the PCB which doesn't look wide enough. My guess it all would have worked just fine. I don't know for how long though. Better be safe than sorry.

Все отлично! Всем доволен. Компрессор классный! Everything is great! Fast delivery! Great seller! Silent compressor! Just right for a laser module!

все очень круто, за проход на 85% и скорость 400 фанеру режет только в путь, гравировка тоненькая линия, а заготовка чуть чуть пожелтела это я без воздуха резал, продавец молодец , отвечает на вопросы быстро, подробно все расскажет и пришлет инструкцию, черный и жёлтый поменял местами для cnc3018. нержавейку граверует, один тест сделал 400*70% . Спасибо продавцу и его группе. 6 заказал 16 забрал.
