Re: 600x600x890 HD12 build

I think all of them are worth doing.. PLA isn't great longer term or near any source of heat. Other than printing nice, I just don't see the point of PLA personally (not a dig, just a personal thought on PLA).

Re: Littl' Plumb Build

There wasn't any crackling/popping noises during extrusion?

Re: Littl' Plumb Build

That looks like extruder issues.. Not pulling the filament through properly?

Re: My 515x515x540 HD12 Build

Well.. In a random turn, and because I can't help but fiddle..

I've ordered a new LGX Lite, 20mm NEMA14, NF-Crazy Volcano and Dragon LC HF..

Whilst I am there I have also ordered a square carbon tube and MGN9 rail to turn it into a HD12 CF X/Y gantry..

Should all be here by the end of the month.

Re: My 515x515x540 HD12 Build

First "big" print.. 6hrs, in Taulman 910 HDT @100mm/s and 8k acceleration. https://i.imgur.com/x3U6Z5N.jpg A decent learning experience.. Print came out well - slight under extrusion. I released it from the bed too soon, so it warped a bit as it was cooling down, also forgot to change support separa...

Re: Littl' Plumb Build

Have you got pics of the issues?

*EDIT* Wait.. Missed the post.

Looks like a mechanical issue.. It is repeating consistently and fairly heavy.

Any more images?

Re: My 515x515x540 HD12 Build

I may print a cover for the IR sensor, after previous experiences with accidentally shorting one.. Although ultimately I might redo the whole X/Y gantry with a CF box and perhaps twin MGN9 rails with a BMG LGX Lite with a Phaeton or Nova hot end.

Re: My 515x515x540 HD12 Build

So, I've been spending time printing with this.. Learning/tweaking.. It's running input shaper via an ADXL345 now which made a huge difference to print quality. I'm trying to get it to print reliably with high quality at about 150mm/s, there is a difference in settings needed to do this vs. 40mm/s! ...

Re: My 515x515x540 HD12 Build

PT100 ditched. Constant issues with Over-voltage etc. High temp PT1000 installed. It prints, just trying to dial in printing at speed.. Still a way to go. Made a loom up and installed my ADXL345 this evening. Will run it in the morning. Maybe after a couple of other test prints. Just messing about w...
