I'm using a small laser machine that only has X and Y axis. When I try to use the Universal Gcode Sender, like to reset the machine, etc., it wants to send Z axis commands and I believe this is jamming up my machine as additional commands don't execute.

My machine uses an Audunio Nano but only has an X,Y axis. I have to close the connection and then re-open it again to return the system back to normal.


Is there any way I can disable Universal Gcode Sender from sending Z axis commands?

One other problem that might be at fault (meaning perhaps sending Z commands isn't the problem) is that when I type $ in the command window I don't see any response displayed of what my settings are. Does this mean my Grbl is not installed correctly on my Nano? I installed Grbl using my Ardunio IDE from the GitHub website.

I'm new to all of this and I just got this laser machine and am trying to explore a little using the Universal Gcode Sender software.


Thanks...
