Preface: This is a diagnostic procedure to collect data on the output of the LPSU. It is not necessary to perform this unless instructed to do so by Thunder Laser USA Support & Innovation Labs. But you can if you like. This instruction is specific to the Thunder Laser USA Nova series machines only.
Using the provided test file attached at the end of this article. Here is an overview of the test file.
Here is how the meter should respond to the test file. Please record the mA value of each pulse in order from 10% to 100%
USING TEST FILE
Current Reading in ma:
If you notice, 70% power and above stayed at 27mA. I rechecked the file to be sure it was correct... and i think it is.
So, we cap our power at 70% in the machine config. This allows us to match the right power supply with the right tube to get our required 10% over published power safely without worrying about current or overdriving the tube.
The plateau may be attributed to that cap. We are exploring this to be sure.
Now we are going to gather these values the manual way as well and compare the data.
NOTE: Just because the results are different, that does not indicate an issue, just a difference.
His machine has the same controller and LPSU as the first test on the Nova 35-80. The only difference is, the nova 35-80 has a C-90 tube and the Nova 51-100 has a C-100 tube, which is largely inconsequential when testing LPSU current output. However, the current draw of the 2 tubes may differ slightly. Everything else in these machines, as it relates to this test, is identical.
Here are the results of both machines side-by-side:
NOVA 35-80. C90 TUBE, 100W LPSU NOVA 51-100. C100 TUBE, 100W LPSU
Nova 51-100 firmware and laser settings:
It appears that Chris' machine has 99% set for laser 1 max in the config. If the above tests were done with this cap, and not out 70% cap, the comparison is not accurate. We are exploring this and will provide updates.
