Octoprint GPX with WanHao Duplicator 4 would wrong temps.

[Davide Spano]

Hello

I have got the printer to work almost I just need a bit of expert advice.

Background.

1. I use Octoprint

2. I have installed GPX plug in in Octoprint

3. I have also installed the Custom Control Editor plugin

4. In GPX Machine Type = Replicator 1 - dual extruder  

5. In GPX GCode Flavour = RepRap

6. Then I have downloaded the MakerBot calibration set beacuse I would like to print the 20 mm cube, simple!     https://www.thingiverse.com/thing:2064

7. In OctoPrint my printer profile is for my WANHAO Duplicator 4 225/145/150 mm, Origin=Centre, Rectangular form factor, Nozzel=0.4, Number of extruders=2

8. I have read https://groups.google.com/forum/#!topic/wanhao-printer-3d/rDewhBxqIJU

9. I have downloaded the config file from that post and made minor mods principally changed the start code because the carriage was crashing to the left, I tested that the changes are correct by creating start and stop buttons with the Custom Control Editor.

10. In Octoprint Cura Engine I use the following profile

[profile]

layer_height = 0.1

wall_thickness = 4

The bits highlighted are those I have changed.

11. I upload the 20 mm cube STL file to OctoPrint and slice it with the Cura Engine with the Printer Profile set to that of my WANHAO Duplicator 4 and Slicing Profile as above. 

12. I get a .GCO file that I load and print

13. The problem 

      The printer moves OK but the temperature of Tool 0 (The right extruder) is set to 70 that is the print_bed_temperature  instead       of print_temperature = 200  and the Bed remains off.

Do you know what I have done wrong and what should I change to get this to work?

Perhaps the profile for the WANHAO Duplicator 4 is not quite correct?

I have read https://groups.google.com/forum/#!topic/wanhao-printer-3d/rDewhBxqIJU but I am not quite sure what to do.

Thanks
