Mr Beam Lasers Support

Indications that something is wrong with the laser head: 

• Does your Mr Beam no longer laser as well after cleaning as it did before? 
• Is there heavy smoke or traces of smoke even though the filters in the air filter system are new? 
• Is your laser head constantly taking cooling breaks?
• Is there no connection to the laser head or does the LED on the laser head no longer light up? 
• Or is your laser head hitting the workpiece? 

In this overview, we have compiled the most common faults relating to the laser head and show you how to rectify them!

1. Laser head incorrectly assembled after cleaning

2. Problems with ribbon cable, clamp or compressor hose

3. Laser head grinds on the workpiece while travelling

1. Laser head incorrectly assembled after cleaning

Has the laser power of your Mr Beam decreased even though you have just cleaned the laser head? Does your laser head keep taking cooling breaks? These symptoms indicate that the laser head has been assembled incorrectly. Below we show you a few places where you need to pay particular attention during assembly.

• Insert the fan the right way round: The fan must be positioned in the housing with the opening facing upwards. It must also be aligned with the bottom right corner of the metal pin. If these two points are met, the text sticker on the fan will not be visible.
  
• Position cables correctly: To ensure that the laser head functions correctly, the cables must not be trapped. This can happen between the two cooler halves or between the fan and one cooler half.
  
• Positioning the laser front panel: To ensure that the laser beam can exit the laser channel unhindered, it must be ensured that the laser front panel is positioned correctly. Ensure this by aligning the opening of the panel and the laser head before tightening the screws.

• Insert the fan the right way round: The fan sits at an angle in the housing of the laser head in order to transport them through the laser cooler. The sticker on the fan must face the floor and the corner from which the cables come must be at the top right near the circuit board. It snaps into place easily when it is correctly positioned. Only then can you close the housing with the second half of the cooler.
  
• Position cables correctly: In the dreamcut [S], the laser diode is connected to the circuit board with extra cables. Make sure that these are recessed in the milled channel so that you can close the cooler halves completely.
  
• Positioning the laser front panel: To ensure that the laser beam can exit the laser channel unhindered, it must be ensured that the laser front panel is positioned correctly. Ensure this by aligning the opening of the panel and the laser head before tightening the screws.

• Insert the fan the right way round: Der Lüfter sitzt schräg im Gehäuse des Laserkopfes, um sie durch den Laserkühler zu befördern. Der Aufkleber, sowie die drei Querstreben des Lüfters muss dabei zum Boden zeigen. Die Ecke, aus der die Kabel kommen müssen oben rechts in der Nähe der Platine sein. Er rastet leicht ein, wenn er korrekt sitzt.
  
• Fully screw in the side screw again: Once you have positioned the fan correctly in the housing, you can screw the screw on the side all the way back into the housing so that the fan is secured again.

Note: Never unscrew this screw completely so that it is not lost and does not loosen any other parts.

• Reinsert the nozzle: In order for the dreamcut [x] to realise its full potential, the small nozzle must always be inserted before the laser aperture is attached.
  
• Positioning the laser front panel: To ensure that the laser beam can exit the laser channel unhindered, it must be ensured that the laser front panel is positioned correctly. Ensure this by placing the left retaining lug in the centre of the recess on the laser head before tightening the screw.

2. Problems with ribbon cable, cable clip or compressor pipe

 Broken or incorrectly inserted ribbon cables, a loosened or broken black clip or even a completely torn off socket on the laser head can also lead to error messages in the software. In this case, contact our friendly support team to find out whether you need to send your device in for repair.

Below we show you how to connect your laser head correctly:

1. Black clip 2. Ribbon cable 3. compressor pipe

1. Black clip

To remove the ribbon cable, you must first push the black clip slightly forwards in a horizontal direction. Never use too much force when doing this, otherwise the clip or even the entire socket will remain in your hand! If this happens, please contact our friendly support team to find out whether you need to send your laser head in for repair.

 The clamp only comes out about 2mm.

2. Ribbon cable 

Caution: You should only pull out the ribbon cable when your Mr Beam is switched off and unplugged! Otherwise this will cause a malfunction of your Mr Beam!

Make sure that the ribbon cable is plugged into the socket with the contacts facing upwards and evenly. 

When the cable has been inserted as far as it will go and is inserted evenly and vertically into the socket, press the black clip closed again.

3. Compressor pipe
With the Mr Beam II dreamcut / dreamcut [S] / dreamcut [x], check that your compressor pipe does not have a visible bend If this is the case, air cannot circulate.

3. Laser head holder grinds on the workpiece

If the metal plate of the laser head (laser head holder) bumps against your material or drags the cut parts around, it may be due to the unfavourable focussing of the laser head. Please check whether the laser head holder is very low in relation to the laser head (i.e. your laser head is finely focussed at the top position). Does it look like this for you?

In this case, we recommend moving the laser head holder with the coarse focussing to the next higher level so that the laser head moves in line with the laser head holder as far as possible. More details on coarse focussing can be found in this article.
