Data format
- Byte = 1 Bit Message Start Indicator + 7 Bit Payload
- Only one message (checksum + command) can be sent per UDP package
- Max UDP package size 1472 bytes including checksum; fragmented by simple cutting (even inside a command)
Checksum
2 Bytes - sum of scrambled message bytes; MSB first.
Checksum has to be send before message.
Values
| Value | Lenght | Description |
|---|---|---|
| ABSCOORD | 5 Bytes | absolute position relative to job origin in µm |
| RELCOORD | 2 Bytes | relative position in µm; signed (2s complement) |
| SPEED | 5 Bytes | speed in µm/s |
| POWER | 2 Bytes | power in 0,006103516% (100/2^14) |
