What parameters are recorded by DevoVision?
DevoVision records many parameters of the machine, that can be exported for additional insights. Read what these measures and their appropriate units are.
To reach the data files from DevoVision, ensure to export the file and save it to your computer. See our DevoVision documentation for detailed instructions.
Parameter overview
| Item Name | Description | Unit | Notes |
| Time | Data recording timestamp | Second (T 0 = log start) | |
| SetT1–4 | Set temperatures of heaters 1 to 4 | Degree °C | |
| Temp1–4 | Actual temperatures of heaters 1 to 4 | Degree °C | |
| dc1–4 | Duty cycle of each heater output (%) | % (0-100) | |
| Err1–4 | Error between set and actual temperature | Number | Number of H1-H4 thermoucouple read errors. |
| intT4 | Reference temperature of chip on Devoboard | Degree °C | Reference for temperature to be used to interpret the Delta of temperatures of the heaters. |
| ExtCur | Extruder motor current | Milliampere | |
| ExtPWM | PWM signal sent to the extruder motor | Number (0-255) | The PWM duty cycle (0-255) of the motor |
| ExtTmp | Temperature of extruder motor | Degree °C | |
| Unused | Unused item (reserved for future use) | Old data, not used anymore. Always ' zero' . | |
| FAULT | Extruder motor fault status | 0 = ok, 1 = fault | |
| SetRPM | Set rotation speed of the extruder motor (RPM) | Rotations Per Minute | |
| RPM | Actual rotation speed of the extruder motor | Rotations Per Minute | |
| FT | Instantaneous filament diameter | Millimeter | |
| FTAVG | Moving average of the filament diameter | Millimeter | |
| Puller | Puller speed or control state | Puller ticks | Tickrate = 2mhz. How many ticks for the system to wait, for the motor to set half a micro step. Motor spec puller wheel: 6400 micro steps per full rotation. EXAMPLE: 2000 tick rate. Wait for 2000 ticks to rotate half a step. This takes LONGER than to wait for only 100 ticks. |
| MemFree | Free memory in the system (for troubleshooting) | Bytes | |
| Status | Overall system status (e.g., RUN, IDLE) | IDLE, HOMING, HEATING, PREPARED, RUNNING, ERROR | |
| WndrSpd | Winder (spooler) speed | 1/100th RPM | |
| PosSpd | Positioner speed (if applicable) | 1/100th mm/min | |
| Length | Length of extruded filament | Millimeter | |
| Volume | Volume of extruded filament | Millimeter³ | |
| SpDia | Spool diameter | Millimeter | |
| SpFill | Spool fill percentage (spooling progress) | % (0-100) | |
| FsIntT | Filament sensor integration time | Microsecond |
