Luckily the new barrel is really easy to unclog. I thought this was a really strange behavier, because the nozzle is hot enought to get the high flow part of the print done but not the low flow sections?!? However after a few more tries of raising the temperature and test-printing, this was my best result and in the end my nozzle got too hot, melted the filament right in top of the barrel and clogged. Another temperature rise later the printer finished printing the raft and then started skipping at the first bottom layer. But I’ve been pleased too early and right at the moment as the printer started with the thin raft lines, the extruder started skipping again. (I think a painfully precise calibration is overkill. I did compile my ‘own version’ from the start code by chrisevich. b) the z-axis calibration code posted by cmeyer never worked for me. Perhaps the info below will help someone in the future: a) I used the start and end code from chrisevich (11) which worked nicely for me. I started a test print and while the nozzle was laying down some first fat raft lines, I was happy that my printer was back in business again. I just wanted to thank everyone who contributed to this thread - it helped me tremendously when setting up my Cetus3D MkII with Cura. There is no silicone sock on this nozzle, maybe raising the temperature will help. (I haven't figured out software leveling yet.) Use Cura or other to position your model in the chosen area, set your settings and make your gcode. The new nozzle arrived but at its first feed the extruder started skipping again while pushing out just a little bit of filament. Here is how I am using Cura with my cetus. ![]() ![]() It was my last nozzle so i decided to order the new V2 barrel and give that wear resistant nozzle a try. I have already had pushed about 3 rolls through its tiny. Tries to clean it failed with the same result. At first i thought it was a clogged nozzle. It already has the V1 extruder installed.Ī few weeks ago my extruder started badly skipping steps while printing PLA. I own my Cetus MK2 for round about 3 years now.
