21. Messages and troubleshooting
Every known message and problem has a REVO-xxxx code – you see it on the screen and in Revo Panel, and quoting it is enough when reporting to service. Full list with fixes: revo3d.pl/en/error-codes.
| Message | What to do |
|---|---|
REVO-0101 File prepared for nozzle … | Install the nozzle from the file or slice the file for the installed nozzle. Print prints anyway, Cancel cancels. |
REVO-0102 File from another slicer removed | Slice the file in [r]evo Slicer or Orca Slicer. |
REVO-0201 Filament may run out | Prepare a new spool or set the correct spool level. |
REVO-0301 Axes are not homed | Tap HOME ALL. |
REVO-0202 Heat the nozzle to at least 180°C… | Loading and unloading need a hot nozzle – choose a material preset. |
REVO-0501 Chamber door is open | Close the door and start the print again. |
REVO-0502 Chamber too hot | Open the chamber door; keep it open for PLA and PETG. |
REVO-0401 Bed heats by itself / Bed too hot | Switch the machine off with the main switch and call service. |
REVO-0402 Bed not reaching temperature | Close the door; if it happens again – Report a problem. |
REVO-0403 Heating error / Heater … not heating at expected rate | Check the heater and thermistor cables; Report a problem. Restart: ⏻ on the bottom bar. |
REVO-0503 Camera: sudden image change | Check whether the print has detached or shifted. |
REVO-0601 Self-diagnostics: worth checking | The result went to Revotech – we will contact you. You can send Report a problem. |
REVO-0602 The PIN was reset | Sign in with PIN 0000 and set a new one. |
REVO-0603 License locked / Trial – days left | Enter the license number in Menu → More → License or contact Revotech. |
REVO-0604 The screen does not respond or looks wrong | Menu → More → Screen mode → SWITCH TO KLIPPERSCREEN (emergency screen), then call service. |
Most common machine setup problems
| Problem | Cause | What to do |
|---|---|---|
REVO-0701 First layer too thin, transparent, the nozzle scratches the bed | nozzle too low (Z offset) | During the first layer use Fine Tuning → raise Z by 0.02–0.05 mm; save the value. |
REVO-0702 First layer round “spaghetti”, does not stick | nozzle too high or a dirty bed | Lower Z by 0.02–0.05 mm in Fine Tuning; clean the bed (no fingerprints). |
REVO-0703 Good layer only on part of the bed | old bed mesh or a skewed gantry | Revo Panel → Bed mesh → NEW MEASUREMENT; Move → GANTRY LEVELING. |
REVO-0704 Print corners lift (warping) | bed too cold or open chamber with ABS/ASA | Raise the bed temperature by 5–10°C, close the door for ABS/ASA/PA, use glue or a release agent. |
REVO-0705 PETG tears pieces out of the plate | adhesion too strong | Glue stick as a separator, bed 70–75°C. |
REVO-0706 Strings and “hairs” between features | damp filament, too hot | Dry the filament, lower the temperature by 5°C, check retraction. |
REVO-0707 PLA clogs the nozzle mid-print | chamber too warm | Print PLA with the chamber door open. |
REVO-0708 The machine asks about the nozzle before every print | file sliced for a different nozzle than set | Set the installed nozzle in Nozzle or slice the file for the right nozzle. |
REVO-0709 The file disappears right after upload | file from another slicer | Slice in [r]evo Slicer or Orca Slicer. |
REVO-0710 Orca does not see the printer / does not send | no connection or a different network | Computer on the same network as the machine; run the command from Revo Panel → Service → SHOW CONNECT COMMANDS again. |
REVO-0711 No Revon printers in Orca | Orca was open during the Revo Sync install | Close Orca completely and start it again. |
REVO-0712 Wi-Fi does not connect | wrong password or a corporate network (802.1X) | FORGET NETWORK and connect again; on a corporate network use a LAN cable. |
REVO-0713 Revo Panel does not open in the browser | wrong address or a different network | The address is on the screen next to the clock; phone/computer on the same network; QR code: Panel on phone. |
REVO-0714 Filament does not go into the toolhead | cold nozzle, squashed end | Nozzle at least 180°C, cut the end at an angle, push until the gears grip. |
REVO-0715 Belt: the print does not slide off the belt | adhesion too strong, belt still warm | Wait until the belt cools, then hold EJECT. |
REVO-0716 The extruder clicks, weak layers | temperature too low or flow too high | Raise the temperature by 5–10°C or slow the print down; check the nozzle flow limit. |

Print problems
- The print does not stick – clean bed without fingerprints; check the bed temperature and the first layer; use a release agent for PETG.
- Strings – dry the filament, lower the temperature by 5°C, check retraction (chapter 19).
- Weak, delaminating prints – temperature too low or flow too high; close the chamber for ABS/ASA.
- Nothing helps – run the machine test and send Report a problem.
