You may be able to fix the issue with your holes by adding more solid top layers in your slicer settings.

The extruder clicking issue is a twofold problem, assuming the trimpot has been adjusted and the screw on the hobbed bolt has been tightened. If your temp is too low, the material will be too soft and the extruder will have trouble pushing it thru the nozzle. If the temp is too high, the material will become too soft around the hobbed bolt and cause the material to bind and the thump of death returns...

I fixed this by adding another fan and shroud to the front of the extruder to get around the poor heatsink design. I have printed ABS as high as 260 with zero issues using the fan.

When I get home I will post the stl file for the shroud. Pics can be seen here:

Heh glad my suggestion was helpful nice work

1. The hotend is moving Up & Down & sides when is printing

It's not loose screws or bolts, as you've discovered. This is the annoying "clicking" issue, so perhaps some of my blog post's solutions for the clicking extruder will help, whether it be higher temperature needed, loose drive gear, wrong trimpot settings, etc. If none of that helps you, it could be something else (but hopefully not).

It's hard for me to tell what's wrong. The first thing I see is that your print is lift quite badly on the corners, so you'll need hairspray or something else. I found that ALL of my prints experience lifting until I started with hair spray.

Is the issue that it didn't seem to print the right model at all? Is it supposed to look like the zig zag arrow in your photo? I found that SoliPrint and Slic3r badly corrupted several models I tried off Thingiverse. The only solution I could find was to use Cura which never showed signs of trouble.

Does the 3D model show the holes after slicing? Maybe it's not using enough fill which is a model issue, and not something I have experience with. You can also check your slicer settings - the extrusion multiplier might be 0.6 or 0.7, but you can try setting to 1.0 (100%) which ensures the plastic extruded isn't limited.

I have some problems with the hotend:

1. The hotend is moving Up & Down & sides when is printing, like this video on youtube zqC4tD5ao78

Note: The screws are very tight so I don't know why the hotend is loose

2. And then start to print with a z zigzag movement   like this video SDC-7BaqhgY

how I can close the holes in the models like the photo (letters F, R, N, A)

Thanks a lot for your help.

Feel free to give me feedback about the post, and my method of solving the problems.
