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.

Re: Hardened nozzles appear to be getting etched anyway...

I printed a couple of small parts with NylonX using the Raise plated nozzles and didn't see anything drastic, but I invested in a set of ruby nozzles when I bought a few spools of CF materials to play with. So far so good with those, and they work nicely with unfilled materials as well. I had an iss...

Yes, fits fine. If the nozzle hex is larger, there's plenty of stretch in the silicone to accommodate.

PEEK Washer/Gasket for Nozzles

I had been thinking about trying some sort of gasket at the nozzle/throat tube connection for some time. I recently picked up a set of Olsson Ruby nozzles so I could start running filled materials. I was skeptical that the torque spec on the nozzles would be adequate to create a seal on the throat t...

Re: Best filament for motorcycle headlight - Carbon + Flex?

My two cents. Use a filled polycarbonate for the headlight surround. It has higher temp resistance than nylons do, and the filing ( likely carbon fiber) really cuts down on warp. I've been messing around with CF PETG recently, and it does print pretty sweet. I also have some CF PC that I haven't pr...

Re: z-banding/print surface quality

I do hear a loud "clack" sound sometimes when the printer starts printing and moves the bed up or down. I can't really make out the source of the sound. Keep your eye on the ball nuts when the print bed starts moving. I think you'll see the ball nuts rotate a few degrees and that clack is...

Re: Inconsistent Z Axis Homing

Are you setting the gap with the bed hot? There seems to be enough thermal expansion in the system that I find it best to set the gap with the bed at print temp and the nozzle close to temp.

Re: z-banding/print surface quality

Do you have any z-hop at retraction? That combined with the loose ball nuts *can* introduce some inconsistency on the Z height as the ball nuts can rotate freely and don't always return to the same spot when they reverse directions. You can test this by eliminating any z-hop at retraction. Then the ...

Re: Another topic about a gap

Are you running ASA with the fan covers on - you don't want any cooling with that material.

regarding PEI - I'm not printing it - I'm using a sheet of it for the build surface.

There seems to be some helpful info about ASA here: https://www.simplify3d.com/support/materials-guide/asa/

Re: Another topic about a gap

I have had good results with Hatchbox ABS and eSun ABS Plus. Between the two I prefer the Hatchbox. It's a little more prone to warping, but the finish and colors are a lot nicer than the matte finish from the eSun ABS Plus. I've had availability issues with Hatchbox, however, so when I was doing a ...
