well ...after following a print from start to the issue I think I finaly find the source. If you look the top right side of the tail the plastic is doing a little bubble, and the hotend is still stuck a short time when going back to the left. I'll do some tests to confirm this feeling. Do you have any advice to avoid this kind of plastic bubble? lower the hotend temp ?by M4vrick99 - Delta Machines
During the first shifting prints the belt was still in the pulley. I've tried tighting it more without any change in the shifts. The alignment is good as the printer was working well during 2 months with very great accuracy ! And nothing moves between this time and now, I've already check the alignment 2 times since the issue is present. The very strange fact for me is the shifting is always atby M4vrick99 - Delta Machines
Hi everybody I have a strange issue on my kossel mini. everything was working good, I was printing all of my parts without any issue. And now most of the prints result with a shift. The shift is always on the Z tower, and always on the same direction. The strange fact is: the shift is always on the same layer for one gcode !!! I've tried several changes to find the source without finding anyby M4vrick99 - Delta Machines
A view of the issue At the top of the image it's mainly good, at the bottom of the image is the spot where the printhead is above the bed. The object is centered on the bed, looks like your idea is good dc42, the bed is not perpendicular to the towers.by M4vrick99 - Delta Machines
Ok I seen what you mean. I do not use Z probe and auto calibration, I found it less accurate than manual calibration. I'll check for twisting and measure every distances between towers to see if I can make any corrections.by M4vrick99 - Delta Machines
your idea sounds great. I've seen the think3dprint3D upgrade, My printer is one of the last before this new version I guess I can try to unscrew the heated bed a little more to move it up on one side. But the gap is on the both side of the X axis, if it's an perpendicular problem there is one side too high and one too low, not too low and each side and good at the center.by M4vrick99 - Delta Machines
Hi all I have some troubles calibrating my new Kossel Mini. The issue is not easy to explain, but easy to see. If I print a ring centered on the bed the first layer is more far from the bed on the X axis ends than all the other parts, and only on the X axis. I guess the smooth_rod_offset is good because the issue is only affecting the X axis, the hotend is printing the same way on the centerby M4vrick99 - Delta Machines
