Every known message and problem of Revon printers has a code REVO-xxxx. You see the code on the machine screen and in Revo Panel. When reporting a problem to the service, just give the code.
First digits: 01 file and slicer, 02 filament, 03 motion, 04 heating, 05 chamber and camera, 06 system, 07 print quality.
File and slicer
| Code | Message / symptom | What to do |
|---|---|---|
| REVO-0101 | File prepared for nozzle … (file for a different nozzle) | Fit the nozzle from the file or slice the file for the mounted nozzle. Print prints anyway, Cancel cancels. |
| REVO-0102 | File from another slicer removed | Slice the file in [r]evo Slicer or Orca Slicer. |
Filament
| Code | Message / symptom | What to do |
|---|---|---|
| REVO-0201 | Filament may run out | Prepare a new spool or set the correct spool level. |
| REVO-0202 | Heat the nozzle to at least 180°C… | Loading and unloading need a hot nozzle – choose a material preset. |
Motion
| Code | Message / symptom | What to do |
|---|---|---|
| REVO-0301 | Axes are not homed | Tap HOME ALL. |
Chamber and camera
| Code | Message / symptom | What to do |
|---|---|---|
| REVO-0501 | Chamber door is open | Close the door and start the print again. |
| REVO-0502 | Chamber too hot | Open the chamber door; print PLA and PETG with the door open. |
| REVO-0503 | Camera: sudden image change | Check that the print has not come loose or shifted. |
Heating
| Code | Message / symptom | What to do |
|---|---|---|
| REVO-0401 | Bed heats by itself / Bed too hot | Switch the machine off with the main switch and call the service. |
| REVO-0402 | Bed not reaching temperature | Close the door; if it comes back – 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. |
System
| Code | Message / symptom | What to do |
|---|---|---|
| REVO-0601 | Self-diagnostics: worth checking | The result was sent 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 the service. |
Print quality and settings
| Code | Message / symptom | What to do |
|---|---|---|
| REVO-0701 | First layer too thin, transparent, the nozzle “scratches” the bed Cause: nozzle too low (Z offset) | During the first layer, Fine Tuning → raise Z by 0.02–0.05 mm; save the value. |
| REVO-0702 | First layer comes out as round “noodles” and does not stick Cause: nozzle too high or a dirty bed | Lower Z by 0.02–0.05 mm in Fine Tuning; clean the bed (no grease from fingers). |
| REVO-0703 | Layer good only on part of the bed Cause: an old bed mesh or a tilted gantry | Revo Panel → Bed mesh → NEW MEASUREMENT; Move → GANTRY LEVELING. |
| REVO-0704 | Print corners lift (warping) Cause: bed too cold or the chamber open 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 Cause: adhesion too strong | Glue stick as a separator, bed 70–75°C. |
| REVO-0706 | Strings and “hairs” between parts Cause: damp filament, too hot | Dry the filament, lower the temperature by 5°C, check retraction. |
| REVO-0707 | PLA clogs the nozzle halfway through the print Cause: chamber too warm | Print PLA with the chamber door open. |
| REVO-0708 | The machine asks about the nozzle before every print Cause: file sliced for a different nozzle than set | Set the mounted nozzle in Nozzle or slice the file for the right nozzle. |
| REVO-0709 | The file disappears right after uploading Cause: file from another slicer | Slice in [r]evo Slicer or Orca Slicer. |
| REVO-0710 | Orca does not see the printer / does not send Cause: no connection or a different network | Computer in the same network as the machine; run the command from Revo Panel → Service → SHOW CONNECT COMMANDS again. |
| REVO-0711 | No Revon printers in Orca Cause: Orca was open while installing Revo Sync | Quit Orca completely and start it again. |
| REVO-0712 | Wi-Fi does not connect Cause: wrong password or a corporate network (802.1X) | FORGET NETWORK and connect again; corporate network – plug in a LAN cable. |
| REVO-0713 | Revo Panel does not open in the browser Cause: wrong address or a different network | The address is on the screen next to the clock; phone/computer in the same network; QR code: Panel on phone. |
| REVO-0714 | Filament does not go into the toolhead Cause: cold nozzle, crushed filament 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 Cause: adhesion too strong, belt still warm | Wait until the belt cools down, then hold EJECT. |
| REVO-0716 | Extruder clicks, weak layers Cause: temperature too low or flow too high | Raise the temperature by 5–10°C or slow the print down; check the nozzle flow limit. |
Power and power outages
Revon printers do not resume a print after a power outage. The available print recovery systems do not meet our expectations: during a longer outage the nozzle, bed and chamber cool down and the print detaches or cracks. We recommend an external uninterruptible power supply (UPS). An online (double-conversion) UPS is a good direction. Its power is estimated from the UPS manufacturer's guidance – roughly 6 kVA. This is a suggestion, not a guarantee: choosing and running the UPS is up to the user and the UPS manufacturer, and Revotech is not liable for the effects of a power outage. We are working on our own backup module.
