"Object reference not set to an instance of an object" I have no idea what that means.
Drilling_holes.zip
I get the above Unhandled Exception error just after loading in a .nc file that was generated by Fusion using their latest grbl post processor. IOsender promptly quits.
I am using v. 2.0.45XL.
Any advice about what is the problem and how to fix it?
I will try to attach the gcode file, which is just to drill 3 holes.
