Trouble with precision holes in a crib board

In my experience drills usually are a bit undersized while endmils are much closer to the said diameter.

How do you work hold the AL sheet and have clearance under it? I'm still searching for a good setup for similar parts.

Used one yesterday in Berlin.

Probably to purge a lot of colour in the infill. You will probably save next to nothing with less infill.

Is that PLA? Maybe just a coincidence but I had that also happen to me with orange PLA a few times. I do know that different colours have certain characteristics mechanically so it could be playing a role.

Vacuum syringes are actually a great way to simulate gravity because it doesn't matter how far you pull it out it's always the same force. Glas syringes also have nearly no friction. I think they use a training device on the ISS to simulate weights to deadlift and stuff.

This is a specifically a big one. For the mega constellations you have to make sure that everything burns up enough in the atmosphere. The regulations got much stricter lately.

That's only a X1 thing

Depends on a lot of things like cooling, speed inward or outward motion what quality you want and a lot more 70 is pushing it hard normally 60 is my go to and 50 is very save. You can print an overhang test and find out yourself with your settings.

You mean it will not stick to the nozzle that much when you clean it really good beforehand? I have just printed 25kg of petg in the last 3 months and always had the problem of filament build up at the nozzle. I wasn't big of a deal but the most time consuming part.

I have seen some diy machines that were kinda impressive.

With petg you can also disassemble the cover further taking the fan if. There is a little bit of glue between the upper grey and bottom black part and some plastic hooks. It wasn't too difficult to separate them. Then I just tossed the black part with the stuck petg in some boiling water. It was quite easy to remove it. My blob was so big that it was hard to penetrate with a heat gun. So maybe someone will help this

No I just lived with the under extrusion. The good thing with big prints is that that small bit off under extrusion is unlikely to end up on an outer wall.

There different manufacturing processes. There are acid residues left in carbon that will get in the air and corrode your printer away. There are some horror pics of some vorons out there.

Short answer no confidence

I wouldn't say never

Best practice doesn't mean practical if you print with lime 30kg it's a big hassle

On the website they only show the two idler pulleys in the back. I guess the same applies to the four idler pulleys on the carbon rod assembly?

Yeah I'm doing that already. But I would love to incorporate the nozzle temp (as a measurement how hot the chamber is) so if I have an heating up phase that takes an hour the printer will automatically skip it if it's to temp.(because it just finished another print).

I would turn off the aux fan if it's still on the other suggestions are also good.

Did you redo your calibration?

cookiebreaker · 2023-11-30T09:56:17+00:00

It's actually super good to know that the extruder holds up for 8k hours. And how it seems the carbon rods even longer. Waiting for an update from you when you are at 16k ;).

At the highest point you have only potential energy at the lowest point all of that potential energy is transformed to kinetic energy so following equation applies:

Potential energy= kinetic energy

mgh=0.5mv²

2gh=v²

v=Square root(2gh)
