CAD model of N2 head assembly

I have a quad-fan plan I want to implement that won't limit hot-end access any more than the stock fan setup. Anyone have a good CAD model of the N2 head assembly with hot-ends in place they'd be willing to share? It's all pretty simple geometry to model up so it won't slow me down too much if I nee...

Re: Layer Shift Pro2 - Assistance Appreciated

If there was a nozzle strike, wouldn't the rest of the print be spaghetti, as the printer doesn't realize there has been a strike (not knowing there has been a physical shift), and would continue printing where it thinks it should be? Also I didn't notice any buildup. I printed a similar piece (the...

Thanks for the info. Sounds worthwhile to me. That Duet web interface looks great.

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

I have been looking at boards and also settled on the Duet 2 Wifi as looking like the best option. It will be a while before I can dig into that though, as I have some work around the house I better get done before I start taking a printer apart. My current plan is to use all stock hardware (I went ...

Re: Layer Shift Pro2 - Assistance Appreciated

You have quite a lot of stringing. If material is picking up on the nozzle during the print, a glob can drop on the build and cause a nozzle strike resulting in a layer shift. On long prints I check the nozzle every few hours when I can. If it's picking up material I will pause the machine and use t...

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

I'll also be watching here.
I have an N2 and N2+ that I'd consider for brain transplants. They've been good machines, but I think 32 bit would be a great upgrade.

Re: Layer inconsistencies / loose Hotend mounting

That appears to be rotational around the nozzle axis - I would not expect that to cause print issues. I don't have the pro so I'm not familiar with that hot end mount. What layer thickness are you running? If you're running pretty thin layers and using Z-Lift on retraction, you might look into this ...

Re: Resuming print

Is there the possibility to start the print job with the "dump file" later. Where is the dump file stored? The question for me is if I need to print something urgent and stop the actual job and start a new job with a separate build plate. Later load the dump file and start the print job a...

Re: PLEASE HELP with ASA

I've never printed ASA. I don't have a PRO. The screws on the flanges of the Z axis ball screws are supposed to be loose to prevent binding.

Re: Raise3D N2 Plus motor slipping

Is the gear slipping/grinding into the filament, or is the gear no longer rotating?

Re: How I more than doubled my print speed while increasing accuracy

Thanks for the update. Wouldn't have expected the bushings to sing. Interesting. If lube is critical something I've done in the past (not on 3D printers) is use heavy felt to retain/distribute oil. Something like a 2mm thick felt washer on each side of the gantry block would keep he shafts lubricate...

Re: Vase Mode

Surely you can't do this in vase-mode? Agree - from what you've shown that part cannot be printed in Vase Mode. You need to have a part with one continuous shell so the nozzle can spiral up continuously while printing. If the printer needs to stop the flow of plastic to move to a different part of ...

Re: PEEK Washer/Gasket for Nozzles

How has that Olsson Ruby been working with the PEEK washer so far? (Oh... and just confirming: you have an N2-series, right?) Yes, I have the N2. The ruby nozzles have been good. Using them for all filaments, not just the filled stuff. The peek washers have been working well. Usually they stick in ...

Re: How I more than doubled my print speed while increasing accuracy

Since you're using IGUS bushings, I'm guessing you also got your aluminum shaft material from IGUS. I'm considering following your lead and doing a similar rod swap and gantry redesign. Was wondering if you considered the hollow 12mm material? Higher moment of inertia and lower weight than 10mm soli...

Sensing an X/Y Shift

At the day job we have a MarkForged MKII printer. I just discovered an interesting feature of this machine. Between layers the head makes a trip to the X/Y Home. I had wondered why it did that. Today I found out. Some support came loose from the bed on the build I was running this morning. I got a n...

I actually rotate it and print it upside down as it is hollow on the inside. Does anyone have any ideas why it would come out like this and what I could do to make it better? So the face we see in the slicer image you are actually printing on the machine bed? In that case the flat face is on the be...
