This means that the bed is curved, and convex. In this case, if there is a larger gap between the head and the bed.In Pronterface - Move the head horizontally.G1 Z0.2 Raise head ever so slightly to give us some room.G1 Z0 Go from home straight down to the bottom.G1 Z0 and the head comes to a rest at the correct distance from the bed.Connect with Pronterface, again, and use the following G-code commands.7:30 Return to firmware, and finely tune MANUAL_HOME_Z_POS in the Arduino IDE, disconnecting Pronterface again and upload.7:11 - Deduction of actual distance from print bed is 1.5 mm.
The paper should move freely, but with some friction felt (you should be able to hear the head lightly rubbing against the paper) G1 Z1.5 lower the head again, but no by so much as before.Paper thickness is 100 microns, place under the head.G1 Z1 and if the head hits bed then this is too close.Connect with Pronterface and use the following G-code commands.3:20 - Initial test - Gap at the center of the bed.2:30 - Ensure that the Pronterface USB port is disconnected as otherwise this will inhibit the Arduino IDE from connecting to the printer.

It is an hour long tutorial video, by Tom of, and it shows you step-by-step how to calibrate the printer, and also how to deal with deformed beds (concave/convex). This video is for a Delta printer, a Kossel XL (although the Kossel Mini is also covered) and it clearly demonstrates the height that the zeroed print head should be at, and how to check using a sheet paper. I seriously recommend that you watch this video #18:Calibration for a great explanation on the use of the paper. Have you manually calibrated the printer (at both the center and the edges), such that you can just about get a sheet of paper between the print bed and the hotend nozzle, at z = 0? This last check ensures that the first printed layer of extruded filament is actually touching and "presses on" to the print bed. Print beds are rarely flat (maybe in 1% of cases they are flat), and are usually either convex or concave. It is actually not that hard.Ĭalibration on any printer is difficult, but especially so on deltas, as there construction is more complex than a cartesian printer. Does anyone know a quick and easy way to calibrate a Kossel Delta 3D printer?Ĭalibration, the part everyone fears. I did some research and it's a calibration issue but I have no idea how to fix it. I have been playing around a bit and I found that the nozzle is closer to the bed in the center than it is near the edge. Upon further inspection I found a bit of play in one of the links, I tightened the bolt and the play is gone but it didn't fix the problem.
The gap grows and shrinks in a parabolic manner and it makes it impossible to get a good first layer. What else could be the problem? Addition info (from comments) I have properly leveled my bed with a piece of paper and have checked the whole printer to make sure it's square but the problem continues. I've been having this problem with my delta 3D printer where my nozzle isn't moving flat with my print bed (as if the bed is bent) but I have used the edge of my steel ruler and it seems to be perfectly flat.
