Getting error 1 in G Sender and when I run a gcode it's like G Sender "thinks" I am running a 30 x30 vs 30 x 48

I have added a PWCNC spindle to my long mill MKII 30 X 48. I am having an issue with running GSender when running G code. I use Vectric software to create my projects. I keep getting error 1 - missing letter and when the code runs it almost like G Sender thinks my work are is 30 X 30 vs 30 X 48. Any suggestions would be greatly appreciated. When I run the grid program fron IDC it runs correctly on the Y Axis but X axis is running 30 vs 48.

@Slvrbullit I’ve moved your post from the UGS category to the gSender question category since you are not running UGS. :grinning:
