I did a print before and after calibration. It looks so much better. Thank you for all you help. I also reprinted the ResMed Adapter Sincerely appreciated it.

I forgot that had to be done as it has been such a long time since I changed the extruder gearing. I also think I found part of the problem and that is one of the screws on the stepper motor mount (on the extruder side) was stripped. I have to drill it out and re-thread it. The extruder spring lever was loose as I watched a video I filmed while printing that last part. You have been a great help and I will let you know how my next print goes after fixing the stripped out screw. I will also calibrate it after that is done.

I first would like to let you know that I am very grateful for helping me out with this. It is not something I have encountered before. I probably do have the units confused. That is what it said on the owners manual for the dual gear extruder. Right now I only use PLA and no it was not specific to it. As far as the holes are concerned, there are none. This is the issue I am having sometimes. Some print just fine and others not so well. Those holes are where the extruder started skipping again for some odd reason. I just printed two other items and keeping the speed set as you had earlier told me and they printed just fine. I didn't change the speed or anything else when this last piece was printed. Pics are attached. I just now started to print a fan mount with ducts and the extruder is skipping all over the place and leaving "nits" as you called them. However, the first few layers printed fine. I even slowed down the print speed to 80% and turned up the nozzle to 205 then to 210 and it is still clicking. (Link to the video is in my Google Drive below) It did not click much at all during the first few layers. The attached 3mf files are Image 1 is the TT_E3D Mount and the TT_E3D BL_Touch Mount (printed just fine) Image 3 is the TT_E3D Fan Mount.

Ok I finally received the parts I needed and printed it. The print looks much better but there is one issue. The extruder I think was not set at the correct mm/min. It was set at 100 and I read the manual again for the new extruder gear and it said to set the mm/min to 139. I am going to do another print but this is what it looked like when done.

Still waiting for my extruder but I tried printing your model just a few minutes ago and it did fine until about 6.5 mm up. Then the extruder stopped advancing filament. The gear was going around but nothing was moving. I think the E3D Hot end got clogged. Just not sure why in the middle of the print because it was doing so well up until that point. I will try again when my new extruder gets here and I will also take apart the heat break and re-seat it. The sides were really smooth and no gaps at all. Thank you for all the help so far. I really do appreciate it.

I also downloaded your code and it won't let me view the properties in it so that I can see the speeds you set up.

Wow thank you for doing that and providing the information for me to look at directly in my printer settings. I also think I may have an extruder problem as I just printed a small square adapter and then a larger mount form my new hotend (to be able to set it up better with a BL touch) Anyway the small adapter printed just fine with very minimal problems. (See pic) The larger part printed horribly. The End stop part came out fine but during printing it hiccuped a bit. Some clicking was noted. I then immediately printed (thinking that one printed well let's try another one) the E3D Mount (see pic) it just screwed up all over. Lots of clicking from the gear on the extruder noted. Although it could be because of the speed differences like you stated. I have since ordered a dual gear extruder and also moved the extruder so that the PTFE tubing wasn't binding when the print got taller. On the E3D Mount I can't figure out why it would print great on some layers and horrible on others except that I have an extruder problem. I have attached the 3mf file if you don't mind taking a look at it also. I will try the code you sent as soon as I extend a stepper motor wire as I moved the extruder as I said above.

Cool thanks. I will change it to Random for future round prints. I also ran Autotune PID for the hotend 3 times using the C3 command and input and saved those recommended settings inside the config file. I have attached the 3mf file TT_ResMed 10 Adapter.3mf

New E3D hotend installed and trying to get the settings correct. Anyway I found I had an extruder problem and that was fixed. I still have some lines but only on one side of the print are they noticeable. It prints well on about 3/4 of the diameter but on 1/4 it seems to have a problem. There is also a vertical line on the rear of the print. I just replaced the stock Tevo Tarantula hot end with a genuine E3D V6 hotend and made the appropriate settings changes in the config file. I am baffled as to why it would print well on part and not so well on the other. I am also not sure why the vertical line is showing up.
