Preface

Based on recent R&D testing, Thunder Laser recommends updating the RF tube Pre-Ignition Mode as a preventative maintenance measure. This change is intended to improve the long-term stability and cutting performance of ET Series RF laser tubes.

This procedure is typically prescribed by support and is ONLY for ET series RF tubes (ET-60 and FT-80).

P.S How to Improve the Stability of RF Laser Output if Having Interruption or Delay Laser Emission Issue

If, after extended use, you experience issues such as broken engraving lines or missing starting points, you can try enabling an external pre-ignition signal.

For ET60/ET80 RF tubes, we recommend starting with a 2% pre-ignition pulse width. Place thermal paper at the machine's focal point on the worktable and check for any unintended laser emission. If laser output is detected when the laser is not supposed to fire (laser leakage), gradually reduce the pre-ignition pulse width by 0.1% each time until the leakage disappears. The recommended setting is the highest pre-ignition pulse width that does not cause laser leakage. In most cases, this value is around 2%. When necessary, the pre-ignition value can be set higher, but please no higher than 5%.

Note: LightBurn only allows the pre-ignition pulse width to be set in whole-number percentages (e.g., 1% or 2%). It does not currently support decimal values such as 1.5%. We have reported this limitation to the LightBurn team, and they may address it in an upcoming update.

Tutorial Video: Set the Pre-ignition Pulse value in RDWorks

In RDWorks, click File > Vendor Settings, enter the password rd8888, then go to Laser and click Read.

Make sure the laser mode is set to RF Laser (Pre-ignition), then set the Pre-ignition Pulse value to 2 and click Write to save the settings.

Next, check whether there is any unintended laser emission while the machine is in the idle state. If laser leakage is observed, gradually reduce the Pre-ignition Pulse value by 0.1 each time and test repeatedly until the leakage disappears. The recommended setting is the highest Pre-ignition Pulse value that does not cause laser leakage.

Tutorial Video: Set the Pre-ignition Pulse value in LaserMaker

Currently, LaserMaker does not provide an option to change the pre-ignition settings directly. If you need to adjust the pre-ignition pulse in LaserMaker, you are supposed to first enable "No Pre-Ignition" in RDWorks or LightBurn. For detailed instructions, please refer to the "How to Change" section. After that, the pre-ignition pulse width can be adjusted in LaserMaker.

We have already reported this issue to our software team, and they may address it in an upcoming software update.

In LaserMaker, click the settings> Vendor setting> password: TL9501> Laser compensate> Read.

Set the Pre-ignition Pulse value to 2, then click Upload.

Check whether the machine emits any unintended laser output while it is in the idle state. If laser leakage is observed, gradually reduce the Pre-ignition Pulse value by 0.1 at a time and upload the setting after each adjustment. Continue until the leakage disappears. The recommended setting is the highest Pre-ignition Pulse value that does not cause laser leakage.
