Hello,

I am building a simple bot using Marlin Firmware and TMC2209 stepper motors. This machine runs the X, Y and Z axis and it's purpose is simply to dispense glue. My issues is that for some reason when I insert an SD card and select a simple g-code program it will run the homing for X, Y and Z, but then commences to only run the Z axis, X and Y will not move. This is frustrating as when I connect to pronterface everything works fine all axis respond. I have tried a myriad of different g codes and sequences and every time it's the same, everything will home, but only the z will run. I have attached my modified Marlin config files along with a one code I've tried to run. I have read through a many different forums, but haven't found any solutions. I have tried using the 998 and 999 dummy thermistors, and have played with the feed rates.

Thank you in advance!

Gcode is by default case sensitive

It Must be upper case, G1 not g1, M106 not m106

all the lowercase lines are ignored, unless you enable GCODE_CASE_INSENSITIVE

Pronterface knows this and converts to uppercase automatically
