<p>This could be caused by under extrusion, often caused by the bed being too close to the hot end / extruder nozzle. You could try to relevel the bed, or change the screws so that the bed moves down slightly. Often when levelling, you want to feel slight resistance when sliding a piece of paper between the bed an the nozzle. You should do this for all 4 corners. Be careful though, you dont want the bed too far away from the nozzle, or problems maybe arise with the print not sticking to the bed.</p>

<p>Hope this helps, Luke.</p>

I just returned from the global readjustements and seems that it's the extruder distance, I tried with the menu settings, but after set "-0.2" the printer says me that this value is out of the interval [-0.5;5]

I'll search the manual option
AJ MM
CC BY-SA 4.0
2020-06-13T14:22:34.583Z
@AJMM This value should not be negative, as the printer believes the nozzle is under the bed. This should be set to 0 as a minimum. Under extrusion is basically when the filament is pushed so hard into the bed, it doesn't come out properly. This is probably what is causing the problems.

@AJMM I would also recommend trying another 3D slicer such as Ultimaker Cura (https://ultimaker.com/software/ultimaker-cura). Also, where do you get your models from. If you make them yourself, try another CAD program, such as Fusion 360 (https://www.autodesk.co.uk/products/fusion-360/overview). It is free for hobbyists and non-commercial uses. See (https://www.autodesk.com/campaigns/fusion-360-for-hobbyists) for help. If you get them on the internet, try a 3d-printing specific model site such as Thingiverse (www.thingiverse.com).

I know all systems that You mentioned, but if I could use Cura, I do it.
In the other hand, FlashForge answer me and the extruder calibration interval is between -0.5 and -5 (all negatives, I thought that 5 was positive); after follow their instructions, now the distance between the extruder and the bed is so little (just the opposite), so I'll report the results to the official technicians and continue reading your aportations.

Thanks so much.

@AJMM I have found some values for Cura. You can download from the Ultimaker website (a quick google search should bring it up. If not, let me know and I will give you the link.) You need to add a custom FFF printer. Then set the x/y/z width to 140. Make sure that origin at centre is checked, and the GCODE flavor is Marlin. Set the printhead settings to: X Min: 37mm, Y Min: 55mm, X Max: 37mm, Y Max: 55mm. Then set the gantry height to 28mm. Set the number of extruders to 1 and the filament size to 1.75. the nozzle size should be set to how big the nozzle is. Usually it is 0.4mm.

@AJMM Are you sure the filament diameter/size is set correctly. For example, do you use 1.75mm filament, but the software believes you are using 3mm filament. The software may believe the filament is bigger than what you are using, leading to gaps. Also, is the filament sticking to the bed properly. Try printing with a raft. This way, even if the first layer isn't great, it will be fine when you reach the model.
