Hello,
I am Prithviraj.poojary. my existing account got spam don't know how, anyway..
back to your question :-
•We are sending G28 command,then only Z axis moves to home position Buy other axis are not moving.
• No we are not getting any Error message in gcode console after sending Command.
•After sending X or Y movement command, XY coordinates are not changing in display.
• It is a delta machine and step/mm for XYZ axis are same.
•Yes we've checked the mapping of X and Y axes to external drivers is correct or not.
Also for better understanding, on monday i am going to share complete firmware.
