Universal gcode sender with GRBL 1.1 in arduino uno

I'm using arduino uno to run GRBL 1.1 code. Connected to Universal g code sender v2.0.7.
It works perfect, but when I use Universal g code sender v2.0.9/2.0.10, its visualizer doesn't display gcode, and Run button doesn't start-up job. gcode is prepared in FLATCAM program.
Does somebody knows solution?

Your post was MOVED to its current location as it is more suitable

As your problem seems to be related to Universal g code sender v2.0.9/2.0.10 does there exist a specialised userforum for universal G-Code-sender?

Another solution might be ESTLCAM.

It is a softwarepackage that can control your CNC with real 3D-milling (not only 2,5D) via an Arduino Uno, Mega or nano
and can create the G-code from DXF or SVG-files

You can test it for free with full function

Hi Stefan,

thanks for your quick answer. I thaught problem was in GRBL in Arduino. After some next tests I've found solution. Issue is in g code file generated by FlatCam program,
the first empty row stops loading in the UGS versions > 2.0.7
So my help request can be closed.
Nevertheless thank you for ESTLCAM suggestion.

Best regards
