Laser Repair near Southampton, on a Lotus Laser BLU100 Machine – Southampton University
A visit to a new customer, University of Southampton requested as the customer could not use their Lotus Laser BLU100 machine as their newly purchased 100watt laser tube would not fire. The laser repair was conducted by our highly experienced service engineer ‘Gavin Edwards’. The laser repair visit included: –
Upon arrival at University of Southampton the machine was visually inspected. The laser machine was in visibly a good condition.
The investigation into the new 100 watt laser tube not firing started with checking the connection were secure and that the were terminated correct, with no loose connections. All connection were tested at the laser PSU and the laser tube. All connections were secure.
The system was tested at the controller to ensure that no actual output was being observed at the laser tube. No output from the laser tube was observed.
The next stage of testing was to isolate the laser PSU, this is done by by-passing the controller signal and testing directly from the ‘Test Fire’ button on the laser PSU. There was still no output observed from the laser tube.
We, as a company, always try to have discussions with our customer before attending site, as if we can fix the problem over the telephone then this is the best outcome for customers. However if an issue does require a service visit then because we have had prior discussions with the customer we are able to bring any potential spares to site. This visit being a good advocate of this process as the engineer had brought a replacement 100 watt laser PSU on the visit.
This 100 watt laser PSU was connected for test purposes and the laser fired correctly. This PSU was then positioned and installed into the machine. Due to the laser tube being a brand new laser tube, a full alignment was required. This alignment was carried out on the machine, which then also brought a further issue to light: –
It was noted that the laser head bracket had become twisted on it’s mounting points, causing the head to sit out of alignment and at an angle, meaning that the final alignment to the Z-Axis was not possible.


The engineer was able to shim the laser head bracketry to enable the laser head to be straightened and to sit in the correct position for the remainder of the beam alignment


Now that the laser head was parallel to the Z-Axis the last stages of the beam alignment were able to be completed. During the alignment process all of the turning mirror were removed, cleaned and reinstated into position. The main focusing lens was removed to be cleaned but was found to be badly damaged around the edge. The customer had a spare lens in their stock, so the 2.5″ lens was replaced.
The remainder of the a standard service items were carried out on the machine: –
- Inspected, cleaned and oiled linear bearings
- Inspected and cleaned electrical bay
- Inspected and tested Safety Interlocks Inspection & Test
- Inspected and tested all sensors
The laser machines laser power was tested at the exit aperture of the laser nozzle and was shown to be measuring 90w @90% power. There was no milliammeter on the machine so it was not able to be limited to a sustainable settings.
The machine was tested by running some of the customer previous jobs on the machine, all tested ok and the customer was happy with the results and the lotus laser repair.
