There are a couple of reasons why your print may not be sticking to your print surface. First, you want to confirm that you are printing on some of the best possible surfaces for your pen. We have tested it on the following surfaces with great success.
- The removable print surface from your MOD-t
- Standard Blank Printer Paper
- a piece of cardboard with blue painters tape evenly applied to it
Next, you will also want to make sure that you are placing your pen close enough to the surface so that it adheres properly. If you have your pen too far away from the surface not only will your filament not adhere to the surface but you will likely create a mess.
