iKier K1 Pro 24 W … there are some problems …
to make you smile: the iKier support team is celebrating the Chinese New Year and will not be available again for a week 
Happy New Year …
… there are still some problems, hints an help
1. The wiring does not work as delivered.
The cable that leads to the laser is either too short or routed incorrectly, in any case it pulls the plug when you use the autofocus. Remedy: turn the cable holder, route the cable around the laser.
**2. The user manual contains a QR code that links to an outdated video. **
Remedy: Thanks to friendly support in the lightburn forum, a link to a more current video and one in German. Thank you for that. [IKIER K1 Pro 20 Watt - #3 by Tilman]
3. Neither the user manual nor the installation video explains what can/should be tested with the “high speed test.gc” file that is on the included stick.
The test did not produce any visible results, after the laser had moved over an area of approx. 250 x 250 mm for about 15 minutes.
4. The user manual describes the setup in lightburn, but important settings, e.g. for the z-axis, are not mentioned.
5. Neither the operating instructions nor the video explain how to connect to WiFi.
After researching on the Internet and lots of „trial and error“, I can suggest the following procedure:
a. Insert the USB stick provided into the controller, it won’t work without it.
b. Install the iKier app on a smartphone
c. As long as the smartphone is still connected to the Internet (via your own WiFi), select the device.
d. Now(!) select engraver as the WiFi on the smartphone. In contrast to some posts on this topic, “engraver” is not the name of the device, but the SSID of the WiFi produced by the iKier. 12345678 worked for me as a password.
e. If the smartphone is connected to the laser, an image (which must be on the smartphone, no more Internet access at that moment) can be engraved from there.
f. In the menu item “Creation” of this app you can see a small work area… I haven’t tried anything else yet, it’s too complicated for me… but obviously you could also use the laser from your smartphone.

6. **The cutting results are poor. **
The values for speed and power given in the table by the manufacturer are not sufficient. Cutting 15 mm thick wood - as stated in the advertisement - seems unrealistic when 3 mm thick plywood cannot be cut.
Remedy: A file kindly provided via the lightburn forum. This file can be edited very easily with a text editor. Important: in the macro definition it must say [ESP500] and [ESP501] instead of ESP[500] or ESP[501]. After I deleted all previously installed devices under “Devices” in lightburn and then installed my device using this file, I was able to cut something for the first time.

7. For completely unknown reasons, some engravings or cuts succeed right away - and now with acceptable quality - but then the laser suddenly stops in the middle of the work area with the message: “The movement limits of the laser have been reached”.
This message occurs frequently. It doesn’t matter whether you select absolute coordinates, current position or user-defined position when “Starting from”. It looks as if the laser doesn’t know where it is at the moment. Remedy: I found out from a post in another forum that a user’s device was pre-assembled, but not all screws were tightened and all cables were laid properly. The user recommends completely disassembling the device and reassembling it; all cables should be laid tightly (so that there is enough play at the end of the cable) and all screws should be tightened. I’ve done that now, but haven’t been able to test it yet, I have to buy new material first
