On the MASSO screen, an accidental Enter before selecting the blank Admin password field closes the setup menu; press Ctrl+L to lock the controller and bring the password prompts back without rebooting.
Can you restore the Admin prompt without rebooting?
Yes. The recovery sequence is Ctrl+L, unlock the controller, then open the F1 screen. Locking prompts for both User and Admin passwords again. If the User password has been removed, press Enter at the User prompt to unlock; the Admin login then appears on the F1 screen.
This addresses a dismissed prompt, not a forgotten password. It restores the login path; it does not change or reset the Admin password. No reboot is required for this sequence.
What does the disappeared menu tell you?
The operator saw the setup menu close because Enter reached MASSO before the cursor was placed in the password input. The important distinction is between a closed screen and a rejected password: no password was entered in the described event. Reopening the Admin prompt is therefore the relevant action, rather than changing credentials or troubleshooting a password error.
The touchpad keyboard is the input device in this case. Its unintended Enter activated the interface before the intended field selection. The recovery is a controller keyboard command, so it does not depend on clicking the now-closed password field.
What should you check before locking the controller?
Before issuing Ctrl+L, confirm that locking the controller is appropriate for the current machine state. The reported event occurred just before a plasma cut; do not interrupt active motion or a cut merely to restore a setup prompt. Wait until the machine is in a state where locking and then unlocking it is acceptable.
| Check | Where | Why it matters |
|---|---|---|
| Machine is not in an operation that should not be interrupted | Machine and controller status | The recovery locks the controller; perform it when doing so is operationally acceptable. |
| Admin password is known | Authorized credential record | Locking requests the Admin password again. |
| User password status is known | Controller login prompt | If removed, the User prompt is cleared with Enter. |
How do you bring the Admin login back?
- When the machine is in an appropriate state, press
Ctrl+Lto lock MASSO. - At the User prompt, enter the configured User password. If the User password was removed, press
Enterto unlock the User prompt. - Open the
F1screen. MASSO presents the Admin login again. - Enter the Admin password to continue with the protected setup task.
If the menu disappeared after an unintended Enter and the credentials have not changed, this sequence restores access to the Admin prompt. It avoids rebooting while distinguishing the User unlock from the Admin login.
How do you verify the recovery?
Verify each stage at the screen: Ctrl+L produces the locked password prompts; the User prompt accepts the configured password or clears with Enter when no User password is set; and opening F1 displays the Admin login. Entering the known Admin password should then let you proceed to the protected setup screen. If the Admin prompt does not appear at F1, recheck that the User stage was cleared and that you opened the specified screen.
The reported controller was running V3.41, with V3.42 mentioned as a newer release. The described recovery is the Ctrl+L sequence; the report does not establish a version-specific difference. Check the behavior on the installed version rather than treating an upgrade as necessary to recover the prompt.
Frequently asked questions
Can I get the MASSO Admin password screen back without rebooting?
Yes. Press Ctrl+L, clear the User prompt as configured, then open F1 to display the Admin login.
Does Ctrl+L reset the Admin password?
No. It locks MASSO and requests the User and Admin passwords again; it does not reset the credentials.
Can I press Enter if the MASSO User password is blank?
Yes. Press Enter at the User prompt to unlock when the User password has been removed.
Does the Admin prompt appear immediately after Ctrl+L?
Ctrl+L brings up the password prompts. After the User stage is cleared, open the F1 screen to get the Admin login.
Can I use this recovery on MASSO V3.41?
The reported recovery used the Ctrl+L sequence on V3.41. After unlocking the User prompt, verify that F1 displays the Admin login on the installed controller.
