It works, which is more than I can say for the 2 USB soldering irons I received from Amazon!

BruceMardle I'm sorry about your finger. I picked up the hot end of a soldering iron... once!

BruceMardle It'sinteresting seeing an Ender-3 V2. I recently bought a plain Ender-3. It doesn't have a bearing block at the top of the (only) lead screw!

Q: What are the pads labelled '8S' to '1S' on the bottom of the board?
尋ねた BruceMardle に 2022-07-02 11:54:18
Z_itriix It is mainly used to distinguish 12345678S during production, and the function has no effect.

Q: Does the LED display show the input voltage or the output voltage?
尋ねた BruceMardle に 2019-04-19 05:36:27
JoGeo It shows the output voltage only

Q: What is the wavelength of these UV leds?
尋ねた BG183915105 に 2021-10-03 04:16:37
BruceMardle I haven't actually tested it, but the product description says 405 nanometres. That sounds right, comparing it with my 405nm laser pointer. The light looks pretty dim but it's not entirely invisible. (It makes a lot of things fluoresce blue, which can be confusing!)

Q: What size holes do these cut?
尋ねた BruceMardle に 2019-06-03 11:32:17
donaldsneffe 4,6 and 8 mm and 3 mm punch, but 6 mm does not cut in mine, it is flat at the end. All in all super poor quality.

Q: Does this do line or cross or selectable? How do you choose between line and cross?
尋ねた Craig Shaw に 2021-01-23 09:06:06
BruceMardle The line laser and the cross laser are 2 separate products (though the cross laser is out of stock as I write this).

尋ねた BG436471841 に 2021-04-07 03:39:09
BruceMardle The 5mW refers to the light output, not the electrical input. Anywhere between 3V and 6V input should work. (I'm not sure if the output is higher at higher input voltages. I don't have mine with me to test.)
