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: Best filament for motorcycle headlight - Carbon + Flex?

I think the heat is from the lamp is a major concern, especially with the housing fitting so close to the reflector and no apparent ventilation to allow the heat to escape. I have done some headlight mods in cars and am familiar with Hella lamps. I'm not optimistic about your design surviving out of...

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 ...

Re: Another topic about a gap

or they're too thin to support the printhead without bending or It's me crazy. Any beam under load will bend. Larger beams bend less. I did some beam calculations for 8mm diameter rods and an estimate of the weight of the gantry - I don't remember the exact numbers, but they were comparable to the ...

Re: End of roll issue

A lot of filament rolls start by passing the filament through a small hole or slot which creates a kink right at the end of the filament. Perhaps this kink caused the filament to hang up.
