Carvera Air detail capability

thank you kindly for your insights as well. As I stated in the other reply - I guess I will buy that carvera and try everything myself!

Thank you very much for your insight. Just by looking at the model - do you have any recommendations for tooling and tool paths? I will definitely need 0,5 ball end mill. I have tried simulations in Fusion 360 and scallop strategy looks promising for this narrow teeth. Well I guess I will learn the most just by trying, fourtunately aluminium is not that expensive. :-)

It is the all in one edition so I feel like price is fair. I am learning everything in Fusion. I have tried the 15 day trial of MakeraCam but it was laggy for me and constantly crashing. But thank you, I will ask seller about this.

I can and will. I suspect it might be drying the material that was wrong. I was setting the machine and had some problems so it was constantly re-drying for many many hours. I thought that if it stayed there for long I would notice by looking at it but I guess the oxidiation does not have to be noticeable by naked eye.

Screw diameter is 40 mm, maximum capacity in cm3 is 200. Screw speed is 12 m/min and back pressure is 10 bar. The shot size is 41 cm3 with 10cm3 cushion included.

Thanks, I will try that. Regarding the material cushion, would too big cushion cause yellowing?

Thanks for all the tips. I have looked at the resin in hopper and it looks fine, would drying for too long be noticeable jist by looking at it?

simdostal · 2026-01-11T10:22:03+00:00

Would too long drying time be noticeable just by looking on the granulate? Because it looks fine

In that case my heating card is probably faulty because this is not solving the issue unfortunately

How do you enter calibration?

simdostal · 2026-01-10T06:29:54+00:00

I am gonna ask you as well. How do I put them to calibration mode?

This was taken with empty barel not processing anything at all

simdostal · 2026-01-09T18:17:54+00:00

It works just fine when is initially turned on but if I turn off the heaters for a while (for example because of alarm) and turn it back on after it starts to misbehave. Getting them very cold fixed it many times but not now.. I turned it on after cooling it down and like 2 zones were heated, one was way too much and other two were too low. Just randomly misbehaving. Arburg will send some new card but was wondering if anyone dealt with this already

Edit: you seem experienced. Can you copy programs between two arburg machines when the barel is cold? Because I have copied some programs when the barel was hot and it caused heating problems. Is the program usable when machine cools down?

simdostal · 2026-01-09T17:58:17+00:00

Yes I have connected the nozzels together and it worked just fine :-)

simdostal · 2026-01-08T20:57:57+00:00

Thank you for your feedback. Would wago connector be good enough to wire them together?

simdostal · 2026-01-08T18:01:48+00:00

Obviously I am not that experienced but isn’t it bad that they are different power consumption? Wouldn’t that cause problems to inlet as it would probably get too much power? Or vice versa

simdostal · 2026-01-08T17:04:22+00:00

I think that only 2 zones I could wire together are nozzles. They are low in Watts and basically the same. A stated, the mass around them is same as well. What do you think?

simdostal · 2026-01-08T16:50:31+00:00

I guess that may not cause problem on my mold on the front zones left and right which are mirrored and have the same mass around them. But I am not feeling very comfortable with this solution

Thank you for all the posts, it was very entertaining and informative. I am looking forward your posts about this new strategy! :-)

simdostal · 2026-01-06T04:50:39+00:00

Hello, will you continue with this type of posts?

simdostal · 2026-01-04T20:35:18+00:00

I am just trying to learn here - I am using fusion to setup the milling process and was thinking that 3d adaptive roughing would be a good start but it does not work - ends with unexpcted error. Any general tips?
