Before sending the job to the lasercutter the driver sends and receives a few preflight messages. | Before sending the job to the lasercutter the driver sends and receives a few preflight messages. | ||
We are unsure if they change when using the Network but they are omitted when saving a job to a file. | We are unsure if they change when using the Network but they are omitted when saving a job to a file. | ||
Some consistencies can be found when examining these messages. | |||
The laser always mirrors messages coming from the driver but changes one of the bytes and appends more data. | |||
For example: | |||
<pre> | |||
# Message by driver | |||
< 0x69 (i) | |||
< 0x34 (4) | |||
< 0xb8 | |||
< 0x4e (N) | |||
# Response by Laser | |||
> 0x69 (i) <-- mirrored | |||
> 0xb4 <-- always changed from 0x34 to 0xb4 | |||
> 0xb8 <-- mirrored | |||
> 0x4e (N) <-- mirrored | |||
# More Data | |||
> 0x36 (6) | |||
> 0x2c (,) | |||
> 0xb4 | |||
> 0x76 (v) | |||
> 0x34 (4) | |||
