Is this an Ultimaker 2?  I guess it must be.

 

Anyway if you want to print over USB (not recommended for tons of reasons but you can do it) then you have to go into cura and add a custom printer and set the gcodes to be in Marlin mode.  The "UM2" machine that comes with cura 3.1 only does um2 mode.  So you have to create a custom printer.

 

Or alternatively and much easier - get Cura 15.*, tell it you have a UM2 but then customize your machine to use reprap style gcodes.

 

The problem is that by default cura creates UM2 style gcodes (aka ultigcode) which works great for the SD card but through USB, your UM2 defaults to normal Marlin gcode mode.

This is not true. At all. You can set the gcode flavor of an Ultimaker 2 printer to "Marlin" in Machine Settings, and it will not use Ultigcode. You do not have to create a custom printer.

Also Cura 3.1 tells the user about Ultigcode when they try to print over USB to a Ultimaker 2 printer, and since OP does not mention that, I doubt that he is indeed using an Ultimaker 2.

 

@Heinerle, if you press the "Print over USB" button in the lower right corner, the printer should start heating the bed (does your printer have a heated bed?) and then the extruders.

Thank you for the replay, I got a Cocoon Create Modelmaker , No heat bed, single extruder.I press to start print over usb but still 0 Temp. will not heat ub.

ather functions will work, i can contoll manually x y z .

i tried all sorts of setting but all the same .

thanks for you help.

Did you configure your printer without a heated build plate in Cura? If not, it may be waiting indefinitely until your non-existing heated bed reports it has heated up.

 

Can you do the following:

* load and slice a model

* start the print using "Print over USB" (Cura now switches to the monitor)

* wait a minute or so

Go to Help -> Show configuration folder

In the folder that opens, zip up everything. Please post that somewhere (dropbox, google drive, whatever floats your boat) and post a link here.
