? Did the laser power get weaker, even though you have just cleaned your laser head?
? Are there fumes and burning marks, even though your Air Filter is new?
? Does your laser head constantly pause for cooling?
? Is there a bad connection between the laser head and the software, or doesn't the LED on the top of the laser head glow?
? Is your laser head hitting against objects on your working area?
--> All these issues indicate problems with your laser head.
In this overview we have put together the most common mistakes around laser head, as well as solutions for these problems!
1. Laser head assembled incorrectly after cleaning
Has the laser power of your Mr Beam decreased, even though you have just cleaned your laser head? Does your laser head constantly pause for cooling? These symptoms point towards the wrong assembling of your laser head. Most of the times it is the fan, which has been aligned in the wrong direction and prevents the air from circulating in the right direction.
Do you see the fins of the fan on the side? Then it's the wrong way!
Do you see the product label on the fan? Then it's also the wrong way!
|The fan should be placed with the opening facing up, the lower right corner aligned with the metal pin of the heating sink.||The cables should NOT be jammed anywhere!|
Sometimes the heat sink covers up a part of the laser opening, if assembled incorrectly. This makes the laser channel smaller, so that less laser light is coming through.
Another common mistake is that the cables of the fan get jammed between other parts:
2. Problems with ribbon cable, cable clip or compressor pipe.
? Are you getting the error message: i2c_bus_malfunction (#117)... ?
? Are you getting the error message:: No laser head found..., even though your laser head is connected?
? Are you getting the error message: no compressor dynamic data...?
Below we are going to show you how to connect your laser head correctly:
2. Ribbon cable
3. Compressor tube
Please make sure that the ribbon cable is plugged into the socket evenly, with contacts facing upwards.
When the ribbon cable is sitting firmly and evenly in the socket, please gently press the bracket back in place.
If you have a Mr Beam II dreamcut, please make sure the compressor pipe doesn't have a sharp bend. Otherwise the air cannot circulate correctly.
3. The metal carriage of the laser head is hitting against object on the working area.
In this case we recommend to hang the laser head to the next level, so that the bottom of the carriage and the bottom of the laser head are more or less aligned. Please find more details about the coarse focusing in this article.
