Bad Print Quality

[Khilborn]

Orest, you should really calibrate you printer using a cube first. You are trying to print a to complex object and your printer is not even calibrated correctly.

The distance between nozzle and hot bed is still not low enough. No gap between the lines of first layer is the best.

I can barely get a piece of paper between the hot end and the bed. Its really snug.

Calibrate it when printing.

In terms of calibration. Is there a procedure that is described somewhere, in terms of what to vary and what I should get? I have not been provided one by Geeetech. Regarding the structures that I printed, I already did a cube and a box that Geeetech send me. This current piece is a calibration piece that I got from RepRap that prints several openings of different shapes. The purpose of the piece is to reveal reproducibility of shapes and to determine if there is rounding. The key point from all of the pieces that I ran is that the bottom layers are messed up and the print quality gets better near the top.

You can smear a layer of glue or spray hair sprayer on bed to let the first layer stick to it.

I finally got a print job out. after figuring out the hairspray / glue on the bed print head heights, etc.

Is there a good document on a calibration on the machine? I just purchased the Geeetech Prusa pro i3b w/ 1.75mm material and .3mm nozzle
my test print looks horrible. almost like the plastic isn't extruding fast enough. When it was printing the infill, it wasn't solid lines. more the size it should be on the ends and stringy in between

I would love to find some test print, already g-code that I could load into Repiere software to test hardware and rule out the slicer and config files.

Thanks

We are preparing the document.

Greetings,

Finally, when I was able to print. i got a very bad quality printing.
I used the setting that you share for Printer I3 B, ABS 1.75, nozzle 0.3 as default when buying.
.
the picture below is talking:

I used Temperture trying from 240 up to 255,a and 95 up to 110 for hotbed
the problem is that the filnamnet is not melting very well and not going out from the nozzle very well, and then not stucking well on the hotbed.
I tried to clean the nozzle,, but still the problem not solved.

Please help to solve this issue, because i spent alot of time trying to run the printer in good condition.

Thanx,

Hi, you can smear a layer of glue if the filament can not stick to hotbed.
And you can refer to the slicer settings at this page:
