Re: Layer Shift

You say the first layer was flat. Not sure what you mean by that.
Is the bottom surface of the failed print perfectly flat?

Re: Layer Shift

There are about 17 different things that can cause layer shifts. A few that come to mind are Condition of the gantry rods (lubrication, cleanliness). Speed, acceleration, jerk settings exceeding machine capabilities (either travel speed or print speed). Material collects on nozzle - drops blob on pa...

Re: What is the cause of these surface artifacts?

3D printing isn't plug-and-play. A different material color, different brand, different moisture level ... or just a different spool sometimes. It will do you good to play with the retraction settings and learn what those settings are for.

Re: What is the cause of these surface artifacts?

What printer are you running?

You need to look at your retraction settings. Retraction, retraction speed, extra restart (might need to add a little negative there) and coast will all impact extra material that the perimeter start point.

Re: Upgraded to a Duet 2 Controller

Working on my N2+ now - here's a shot of the board mounted using the brackets I shared above. I replaced the blower with a 24V unit, and also removed the standoffs in the case which space the blower away from the back of the box. On my N2+ (cover screws on the box) there were inserts in holes that s...

Re: Has anyone done a 32bit upgrade to the N2 series?

A brief follow up on my experience with an N2 running with the Duet2 Wifi board. Real happy with the outcome. The touch screen is not in used. I got an old iPad2 from my daughter and have that by the printer just with the web browser for printer control. Landcape - Portrait mode cuts down the number...

I've had some that were tough to unscrew, but never to the point of damaging the throat tube.

Re: Gantry sag as seen by a BLTouch

I spell out some of the process in a few posts here: https://forum.raise3d.com/viewtopic.php?f=17&t=17428#p54231 I have the advantage of having two printers, so while one was down for the upgrade I could make the parts I needed. It's far from a plug-and-play endeavor, but there weren't any major...

Re: Magnetic build plate

Yes, my printed tabs are .5mm up from the bottom of the plate, so the spring clips pull the aluminum down to contact the hot-plate.

Re: Moving print area

On my N2 & N2+, I wanted to get the clips out of the build area. I moved the heated bed 12mm forward (toward the door), and also moved the Y endstop switch by 12mm toward the door. With that I was able to get 300x300 of clear build area, and also was able to add some attachment clips to 12x12 sq...

Re: Replacing print head linear bearings ?!?

Last night I replaced the crappy Amazon bearings in my N2+ with the THK bearings. I still have the factory bearings in my N2. The THK bearings eliminated the play I had with the Amazon bearings, but I can't claim that they are better than the original bearings in the N2. Based on my cost for the THK...

Re: Octoprint and hacking the touch screen?

Hey @zemlin, I'd like to run native octoprint on the unit. Have you been able to make any progress on this? I have not, and the Duet Web Control interface doesn't do as well in a portrait mode display - so I haven't put any more effort into it. My daughter had an old iPad that is working well as th...

Re: Spectrum PETG

Some PETG bubbles if the print speed is too slow. I normally print PETG with a 0.6mm nozzle. You don't want the print speed too slow either. I generally run at least 60mm/s to keep the flow rate up. I've never used Spectrum PETG, but the comment you make about retraction could be the material being ...

Magnetic build plate

A colleague showed me the flexible, powder-coated PEI, spring steel build plate from his Prusa printer. I love PEI as a build surface, but have been looking for a way to get rid of the double-sided adhesive for quite some time. The bed on my N2 and N2+ printers has been modified with 4-point adjustm...

Re: Missing hole in print using vase mode

On the tube_test.stl file there is a pocket on the bottom of the part, so the first couple of layers would print with a hole. If printed solid there would be a pocket on the bottom with support structure required for the top of the void. Looking at the model in IM again, I see the default first laye...

Re: Missing hole in print using vase mode

I compared S3D and Ideamaker on the Tube Test part - S3D leaves the hole on the solid layers. Ideamaker does not. Vase mode, one solid layer is what I set up.

Re: Some beginner help please

1) You do not need a raft. A raft helps compensate for build surface irregularities and some folks prefer the appearance of the build on a raft. The bed clearance to the nozzle is not as critical either. It adds to the build time though and many folks do not use them. I do not. 2) That is perimeters...

Re: Strange first layer problem with E2. one side of models

If you're using M572 you could try stepping that up a bit to increase the initial nozzle pressure.
