If a controller reports low DC power while a connection fails, preserve the exact message and stop repeated job attempts. That wording carries information a generic connection error does not. Send the error and machine details to the manufacturer before replacing hardware or repeatedly reinstalling software.
In a recent LightBurn connection thread, a user reports intermittent connection behavior alongside a low-power message. The discussion concerns a different setup and includes troubleshooting suggestions. It does not identify an X1S Pro defect, establish that TYVOK controllers display the same message or justify copying another user's power-supply experiment.
Preserve the sequence, not just the last popup
Write down whether the message appeared at startup, during connection or after a job command. Keep the full console text around it when available. An isolated screenshot saying “cannot connect” may omit the power warning that appeared immediately before it.
Record what worked most recently and what changed since then: the computer, software version, connection method or machine configuration. Separate observed facts from guesses. “The warning appeared before homing” is useful; “the software update broke the power supply” is an unproven diagnosis.
Do not perform live electrical measurements, open a power supply or substitute a unit based on a forum reply. Follow the manufacturer's shutdown procedure and request instructions appropriate to the actual machine. A support case can proceed from the evidence already visible without another speculative cutting attempt.
A useful X1S Pro support packet
| Include | Keep it specific |
|---|---|
| Machine identity | Model, supplied configuration and support identifier |
| Exact message | Full wording and nearby console lines |
| Timing | Startup, connection, homing or job stage |
| Software | Application and operating-system versions |
| Recent changes | Only changes that actually occurred |
| External labels | Readable details requested by support, with power safely off |
Avoid posting private account information or purchase details in a public forum. Send the necessary identifying material through the manufacturer's support channel and retain a copy with the job record.
Keep software symptoms separate
The TYVOK X1S Pro listing describes a large-format diode workflow with LightBurn support. It does not establish the meaning of an arbitrary third-party controller's warning. Use the actual X1S Pro configuration and manufacturer guidance to interpret your machine's condition.
A license error after reinstalling LightBurn belongs to a different troubleshooting path. Reinstalling may change the software state while leaving a supply warning unexplained. Similarly, live speed and power overrides are operating controls where supported, not a remedy for a power-supply warning.
Keep affected material and the stopped job file identifiable until support clarifies the next step. That prevents another operator from treating a partially processed panel as a successful sample or resuming an uncertain setup simply because the error disappeared once.
Should I buy a higher-amperage adapter to see whether it helps?
Not from this message alone. Connector, voltage, polarity and the machine's requirements all matter, and the warning does not identify a compatible replacement. Obtain the manufacturer's diagnosis and approved replacement specification if one is needed.
If the machine reconnects once, is the problem resolved?
One successful connection does not explain an intermittent warning. Record the behavior and wait for the recommended checks. Resume production only after the manufacturer-supported procedure establishes that the setup is ready for use.
