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.

I understand. Do you know what extra restart is? Have you tried it to see if it makes a difference?

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

I hadn't noticed it was after the seam - try some extra restart. Since you don't have a gap you shouldn't need much to boost your output. If you're running a .4mm nozzle, .1mm or .2mm should be enough to notice a difference.

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

You should be able to get the perimeters to fuse by increasing the flow - going too far could create other problems, but turning that 'knob' should make a difference.

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

Could also be impacted by extruder calibration and z-offset.

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

I don't know the E2 machine, but in my experience asymmetry usually indicates a cooling issue - where one side is getting more cooling than the other.

Re: Replacing print head linear bearings ?!?

I ended up making some retainers to hold the bearings from the outside. No play issues in my cast N2+ block. I wasn't happy with the Amazon bearings though. I decided to see how 'name brand' bearings would compare. I bought a pair of THK bearings from Misumi ($53 for the pair w/ shipping). Holy crap...

Re: Under and Over Printed Corners

Looks like you might benefit from some extra restart on the extruder tab. If it's just a little short on laying down the first bit, the error will accumulate on subsequent layers and the gap gets bigger. Once it creates a small gap the next restart doesn't have anything to land on. That can also con...

Re: Feature request: Live Z on first layer

I just swapped the control board in my N2 for a Duet 2 Wifi. The web-based control interface for the Duet has a live micro adjust for the Z - it's real nice. I don't use it much because I also installed a BL Touch probe - but when I don't quite nail the Z offset the microstep is handy.

What material are you printing? I printed a 3KG PETG part covering nearly the entire bed a while back. I don't have the Pro - this was on an N2+. My first attempt was using a magnetic spring-steel bed and I had a similar issue. Enough warp in the part that it lifted the bed and caused the print to f...

Re: PETG print problem

Have you tried slowing down? With a 0.4mm nozzle I can't print PETG faster than 50mm/s or the extruder backs up. Maybe you just have too much back pressure and aren't extruding consistently.
