This guide assumes a basically properly built and calibrated printer Main_Page. This guide is not intended as a design guide, but more as an operational troubleshooting guide.
If you have not read through and attempted a complete calibration, see the REPRAP wiki for Calibration instructions. Some common calibration issues as well as common build related issues however are discussed.
(Please note: This guide is for identified and resolved issues only. The more common the issue, the better. No questions or open issues belong here, go to the forums for interactive help (look to your left in the links column). Use clear and concise language, only 6 pics or entries per issue.)
The following categories are used to help identify the print issue by either print defects or by cause (if known).
The print defects will point to identified causes and branch into individual examples and solutions:

Prints do not adhere to build platform.
|
Print head too high to push plastic against build platform
|
Change height settings to no greater than nozzle diameter above bed, calibrate bottom stop, level build platform
|
| Tall parts tend to detach before build is complete. | Too low of contact area for the height or too low adhesion. | Select to use a raft with a larger footprint to aid adhesion, or use skirt with zero offset to increase base area. | [9] |

Printed parts adhere to the print bed too aggressively. Shown ABS printed on heated PC (polycarbonate) sheet.
|
Bed material selection needs to be compatible with material printed and temperature used.
|
PLA on heated glass works well as a build surface, Blue painters tape unheated works well for PLA, ABS on heated bed with Kapton tape works well, ABS on heated bed with PET tape works well. See build forum for examples and suggestions.

| Printed parts adhere too aggressively. Shown ABS on heated glass took chip out of glass. | ABS may adhere too aggressively on uncoated glass. | Use Glue Stick, Kapton, or PET tape on glass for ABS. See build forum for examples and suggestions. | [12] |
