Great, thanks for the fast response!
Ok so the firmware is:
21:16:48.733 : FIRMWARE_NAME:Repetier_ http://omni3d.1688.com/ PROTOCOL_VERSION:1.0 MACHINE_TYPE:Mendel EXTRUDER_COUNT:1 REPETIER_PROTOCOL:2
Everytime I send an M501 when it's printing I get the:
21:18:08.951 : Info:Configuration stored to EEPROM.ok 44869
21:18:08.951 : Warning: Missed line detected - correcting buffer usage.
And when it's not printing I get the:
21:21:46.245 : Info: 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
21:21:47.235 : Info:Configuration loaded from EEPROM.wait
Also when I type for example M92 X80.00 nothing happens
Strange thing is that I am able to send prints and other commands from repetier host like move the bed or heat op the hotend,
Any ideas are more than welcome :)
