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...

Re: How do I get a rounded edge?

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...

Re: What would you adjust in the settings to fix this?

Your 'boogers' are likely from nozzle ooze when it is moving between the towers. You might try increasing your retraction and/or z-hop. If it is, in fact, ooze getting wiped off on the outside, a large enough z-hop should cause the printer to deposit the ooze booger inside the part before it starts ...

Re: Adapted Olsson Ruby nozzles

fwiw - I've been running Ollson ruby nozzles with no mods. I did have sealing issues against the throat tube, however - I started using a PEEK washer as a gasket between the throat and nozzle. It's worked well for me.

Re: Underside of prints looking rough

Hi Zemlin, thanks again. I've got a couple of follow up questions. I normally use a separation of one layer. Where do I specify this in IdeaMaker? It's called Vertical Offset Top for material building on top of support. Vertical Offset Down Layers for support that starts on top of the build. My sug...

Re: Underside of prints looking rough

Another thing you'll be learning soon is that with some materials the overhang will tend to curl up when printing regardless of the support you build underneath it, and that can lead to a rough under-side as well. Just something to watch for, and may drive you to settings on support that make it a l...

Re: Underside of prints looking rough

In working with support the layer thickness of the build is an important variable, as you can only specify the separation from the support as a number of layers. I normally use a separation of one layer. My suggestion would be to make a small test part that requires support on a shallow-angle surfac...

In that photo of the first layer, the bed is not true to the nozzle - where it gets too close you can get the squiggles. Backing down on the flow rate will help with that, but you might need to tweak the bed as well.

Re: Top layer issues

Overextrusion. Around holes like that the surface fills in patches. Your ridge is where one patch stops and the next starts - they are printed at different times and the overextrusion builds up excess material. your test square paints the surface uninterrupted from one corner to the other. That's wh...

Re: ABS/raft almost single part

You have complete control of raft adhesion. There's a setting for the separation between the build and the raft. Don't have IM in front of me, so can't give you the exact name. Increase that. I often start with that at 80% of the layer height and adjust from there to get the raft adhesion I want. Th...

Re: Can't print with Hatchbox ABS

How's your bed clearance with the bed and nozzle at temp? Wondering if your nozzle is dragging on the bed and just closing off the flow. PLA runs a lower bed and nozzle temp so it's going to have a little more clearance with the same machine settings. You might also check your extruder spring tensio...

That's a good point, but does introduce the need to home for every temp range you choose to use. Eeek!

Setting up for a new part usually involves a material change, often a bed change, maybe a nozzle change - homing the bed is just part of the setup and no big deal to me.
