That does not seem to work. the 'initial_extruder_nr" value seems to match the value that cura automatically places at the beginning of the gcode. The only way it seems I can get it to change to T1 (left) is by selecting a 'Build Plate Adhesion Type' and choosing Extruder 2.

Good news, I found that if you add the following line, between the square brackets, to the definition file ["machine_x3g_variant": "r1",] and check "Origin at center" in the machine settings the printer operates as expected. I made some additional correction/modifications to the definition file which I will upload once I iron out the last bug I am running into. When trying to use extruder #2 (left) it will heat fine and 'T1' will appear at the top of the gcode when "Build Plate Adhesion Type" is used and 'Extruder 2" is selected as "Build Plate Adhesion Extruder". However if I select "none" for "Build Plate Adhesion Type" it will only heat extruder #1 (right) and Cura always places 'T0' to start the gcode. I am using M104 S{material_print_temperature_layer_0} in my start gcode. Any thoughts?

I did try that previously with very similar results as "Origin At Center" unchecked (which seems unusual in its own right). I will try slicing again in cura with Origin At Center checked soon. I am battling my COM port connections now, trying to stream gcode commands to my printer to troubleshoot a cooling fan issue. But once I resolve that and get some clean prints in makerbot desktop I will get back into Cura. I enjoy Cura and would prefer to use it as a daily driver.

I setup in makerbot desktop and had much more success. It is printing normally, I have attached that Gcode. It seems to be more successful by moving the head to the front left of the printer during the heating phase and then starts the print. 3DBenchy.gcode

Since my home is the back right corner and the bed raised all the way up, I wonder if the gcode thinks my home is somewhere else, such as the front left corner and is just hitting the stops for x and y. Also I did locate the home offset on my machine is X:146.198mm, Y: 73.497mm, and Z 0mm. Toolhead offset is X: 33.387mm, Y: -0.074mm. I am not sure why that would impact it as those numbers have never been changed since I owned the machine, but I figure it is worth bringing up. I will try to connect my printer via USB and jog it using my computer, maybe that would provide some results.

I also attempted to use the Makerbot flavor of gcode with origin at center unchecked and it did a similar thing to Marlin with origin at center checked. It first homed, then dropped the bed all the way down until it almost hit the bottom (there is no end stop on the bottom of the z-axis). Once up to temp it started printing in mid air in the back right corner. Also it seems like the extruder is trying push out way more filament then it needs to, I can hear the gear skipping on the filament. This does not happen when I use the printers LCD to load filament. Within the extruder settings the material is set correct (1.75mm) and the nozzle size is correct (0.4mm) All these prints have been set with a layer height of 0.2mm, also heated bed has been checked and heated build volume is unchecked. I attached the gcode for the makerbot version. WD4S_3DBenchy (makerbot).gcode

Thanks for the quick reply!! I unfortunately do not have the original files with the printer and I have gotten it running years ago but with different slicers. Unfortunately I do not have any of the original g-code just .x3g files. I attached two gcode files of benchy. One with the origin at center checked (as indicated by the file name) and with origin at center unchecked. Both have the flavor of gcode as Marlin within Cura. I cannot find zero on X or Y because when I jog in the LCD menu, it does not indicate position. When I do home it puts the head in the back right corner and raises the bed all the way up. One interesting thing I noticed is when I ran the .x3g file for "origin center checked" it dropped the bed most of the way down and was printing in mid-air, however with origin center unchecked it did not drop the bed. In both cases the extruder was attempting to print in the back right corner and the benchy is centered within Cura. WD4S_3DBenchy(Origin at center-Marlin).gcode WD4S_3DBenchy.gcode

I am running into the exact same issue. The bed and extruders now both heat up with your definitions file but it prints in the back right corner opposed to the center of the bed. It also jogged the z-axis down a few millimeters even though it was already homed, not sure why but it is just something I noticed. I am running sailfish and the printer does home in the back right corner and home in the center is unchecked.
