Problems with very early version of gSender

I keep having dropouts with Gcode sender. Even when I’m jogging the machine around with the keyboard. The Topo sign done in Vectric the most I got was 2 hours in with Gcode Sender. Finally I gave up and cut it in UGS without a problem. The cutting board done in Fusion 360 Gcode sender failed once on the rough pass, cut the finish pass fine, then failed 7 times on the cutout pass till I gave up and just finished cutting it out on a band saw. I do alot of longer jobs and I am really having a problem with reliability with the new app.
