can control the motor in Pronterface but g code command not executed

Dear All,

I'm a newbie here, I'm using Ramps 1.4 to control my stepper motor. I found that I can control the motor by pressing the buttons on Pronterface UI (for example, by pressing the z motion button in the Pronterface UI my stepper motor can run). However, if I just type G0 Z10 or other G code in the Pronterface UI and click send, the G code is not executed.

I'm using Marlin 1.0.2 firmware, Win10 OS.

How should I send some simple G code commands to the machine? Thank you in advance for the help.

... try sending "M114" or "M119" - if you don't get response from the firmare, then your sender/receiver-functions won't work ...

Thank you for the suggestions. I tried M114 and M119 and I can get response from the firmware.

When I connect the machine to Pronterface, send g0 z10, it will run for the first time. When i try to send another g0 z10, it won't run. I have to disconnect and reconnect the machine to let it execute the g code, but again, it only response to the first g code that I send, and not response for my second g code command. Meanwhile, I can still use the button on Pronterface to control the z motor.

Any suggestions? Thank you.

... this is simple - if you move it to Z=10, then a new move to this same position won't do anything (it's already there) ... move it with "G0 Z20" away, then "G0 Z10" will work again

... this will be different, if you change the mode from "absolute" (G90) to "relative" - send "G91", then every "G0 Z10" will move the Z-axis 10mm in the same direction
