If your printer’s not enclosed and you don’t have the fan on then I would suggest making sure there are no vents blowing air while you’re laying down the first layer. It’s not the “smooth finish” everyone seems to covet, but it’s way better. And, the first layer of print quality improved a lot. What I did was set the fan to start up after the print had cleared the base layers, after the raft. I have a Monoprice Voxel printer, which is enclosed, and I was having the same problem due to the fan. The first layer above the raft is actually literally above the raft, so if the material dries too fast as it comes out of the nozzle it’s not able to adhere at all to the raft. Or, if you are in an uncontrolled space where your printer’s exposed, there may be too much temperature variation or air movement - over cooling things. Hi - so I know this was a few years ago - but for you and anyone else who ends up here I believe I have a good answer to this problem: it’s actually the fan cooling the first layer extrusion down too fast so they are not able to adhere. One way to tell if there is a small blockage in a nozzle is to initalize the printer, and then set it to extrude fillament - if the fillament does not fall straight then that is a sign of a blockage - I have had issues with this and designs sticking to rafts on another 3d printer but not the Cetus. ![]() We have got a 0.2 mm Nozzle for fine and sharp detailed printing, a 0.6 mm one for printing big and structural parts, and a 0.4 mm option for the general-purpose printing needs we may come to face. ![]() I changed the distance by 0.05, but you can make changes as small as 0.01.Īre there any other issues, such as signs of a clogged nozzle, try changing the nozzle and see if this makes a difference. The Print Quality of Cetus MK3 is really superb due to the Variety of nozzles provided with the printers. Where you say that you have calibrated the bed, do you mean the nozzle height? If you do mean this it might be worth adjusting the height of the nozzle so that it is slightly closer to the bed, I did this with mine and did small test prints until I was happy with the result as I had loose rafts, but they did still stick to the item I was printing. Are you printing with PLA or another material, are you now printing larger items than you were previously or are you getting the same problem on some prints that you have had success on previously, have the conditions where you are printing changed at all - ie the printer is now nearer to a draught in the room, although this would matter more on ABS than PLA. ![]()
