Hi, I copied the reprap files into the sd card and connected to the printer through the web control. So the first thing it wants me to do is the homing of all the axes. So I click Home all. C, Y,X home perfectly fine. But the Z moves down, away from the endstop. So I flipped the direction of the z axis in the config.g file. Now when I "home all", the z axis crashes into the tool head pressing against the end stop switch. What do I do Also, My tool head is perfectly grabbing the tools but I am not able to set the temperatures on my bed and the tools. They are not responding. What do i do for this
Whats in your homez.g? Move the Z-Axis the right way if you move it with the Buttons on the Webinterface?
I was wrong about the z axis direction. I switched back the directions back to normal as I downloaded. Now when I press "+5mm" the bed goes down, so the direction is correct. I am attaching the homez.g file and the config.g files for the reference. I cannot figure out a way to home the Z axis and get the nozzle and the bed temps up. This is my homez.g file : Code: ; homez.g ; called to home the Z axis M98 P/macros/Coupler - Unlock ;Open Coupler G91 ; Relative mode G1 S1 Z5 F5000 ; Lower the bed G90 ; back to absolute positioning G1 X150 Y100 F50000 ; Position the endstop above the bed centre G91 ; Relative mode G4 P500 ; wait 500msec G1 Z-300 S1 F1000 ; Move Z down until the switch triggers (first pass) G4 P500 ; wait 500msec G1 Z5 F5000 ; Lift Z G4 P500 ; wait 500msec G1 Z-300 S1 F300 ; Move Z down until the switch triggers (second pass) G4 P500 ; wait 500msec G1 Z5 F5000 ; Drop the Bed G90 ; Back to absolute positioning this is my config.g file : Code: ; Configurat; Configuration file for Duet WiFi / Ethernet ; executed by the firmware on start-up ; General preferences M111 S0 ; Debugging off G21 ; Work in millimetres G90 ; Send absolute coordinates...

That's one of my concern, when i start the printer, I find that the red light beside the Z motor connector on the duet board is on by default. When I push the button by hand, the light goes off. But when the Z axis is moving, and i press the button, the motor doesnot stop despite the red light going off. I am attaching pictures for reference.
Homing Z using a Z probe (which is what the switch is) should be done using a G30 command, not a G1 S1 command. See https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z.
Can you send me the files in your sd card. Mine are all messed up. That's what causing the problem I guess. I cannot seem to get the printer recognize the nozzles and the bed.
download the config from here | https://github.com/e3donline/RepRapFirmware-SD | copy it to your SD card and overwrite any files prompted at.
