unknown command and communication timeout
i use radds/due and Repetier Server 90.4 on raspi3.
Firmware is Repetier 1.0.2
Raspi is connected via 20cm Usb cable to due and via lan to Network.
i tried to print one model several times , but unfortunately i get lot of Messages with unknown command .
some communication timeouts also happen , which cause a big blob in print.
Asi cannot find anything Special in gcode file I´m not shure how to fight against this.
tried to increase buffers in Firmware from 30 to 50 , then to 100 same result.
tried to increase baud rate from 76800 to 250000 , no Change.
tried to update Server from 90.4 to 90.6 , no Change
also tried direct print via USB, no Change
the Special on the model is just that is has extreme high quantity on small segments.
Log Shows only the Messages with unknown commands and communiation timeouts.
print Speed is 120mm/s , travel Speed is 800mm/s
additional info : slower print (at 70mm/s travel Speed 800mm/s) succeded
(may be there is enough time for Software to fix communication timeouts)
as i cannot find anything Special in gcode (only G1 moves in the file) the question:
are lines starting with ; in gcode interpreted as unknown commands?
and : can a couple of unknown commands cause a comunication timeout?
what can i do to solve this Problem?
