I’m 3 years into my lemon road. 
that sucks…it seem Aillio wanted to rush out a new product, and I get the need, but nothing is updated for the R2 versions: website, roast world and community. I guess I will see how I am doing in 3 years.
It depends on the complexity of your issue or the nature of it.
Aillio tech support does not acknowledge convective roasting in the bullet. So they won’t look into anything to do with air or airflow. Yet they install an airflow sensor on the R2 and R2Pro? Seems a bit like they are admitting airflow is importantly enough now? Yet they still disregard my findings. I even had to prove to them that my board had power issues. That was almost a 2 year process. They are pretty bad at listening to customer input, so if they don’t discover the issue or it isn’t plainly obvious, they kind of write you off.
I have seen this before: its like the connectors on the R2 Pro, we spent a lot of money on drum, sensors, and heating, so lets save a dollar on usb connector and cooling tray connector, the lack of function controls by using less function buttons, chaff collection screen, and most concerning manufacturing issues.
Yes, understandable in some ways and nearly h forgivable in others. Haha. I don’t know why, but I hate pressing “-“ 9x to turn off the cooling tray fan.which can also end up adjusting the fan or drum in a back to back roast. I should have made my own cooling tray a long time ago.some of the mods and diy’s here on the forum are down right genius
Hi Dave,
I am sorry that your Bullet was damaged during shipping, and you feel disappointed.
It seems like all your issues stem from the broken control assembly (except the smoke during seasoning), so I am confident that once you receive the spare part, your R2 should work.
Just to shine a light on a few things. We had the new shipping box tested by a 3rd party to ensure that it could pass the standards for being dropped etc. They did this on all sides and corners and it passed.
Needless to say it was a big surprise to learn that some Bullet’s control panel were damaged during shipping (you are not the only one).
We have since removed the control panel and require users to mount this as part of the setup routine. All damaged control panels will of course be replaced by us.
As for the USB connector this must have been broken during the impact as well and should explain your connection issues with RT.
I can assure you that we use only high quality components from the best manufactures and our goal is to have the highest reliability possible.
Please let me know if your new control panel fixes all the issues. Your feedback is really appreciated.

I’m wondering if my R2 Pro will arrive DOA. Their saying yours isn’t the only one that was damaged doesn’t breed confidence. I realize they are watching out for themselves, but we customers should also be protected. Aillio has a well earned reputation with the R1 lineup that they need to live up to with the new lineup. I’m hoping they take care of things properly.
My R1 has never operated correctly. so, I don’t really agree with that statement. The company is pretty new.
Well, that is true. Yours has had problems that by now they should have fixed. It just sounds like the R2 units are having lots of problems with lots of units. I haven’t read of that many R1’s having problems. Then again, most of the folks commenting on their R1’s are the people with functioning units. It would be helpful to hear from more users like yourself who have faulty units.
Well, the Aillio brand is a “disruptive” sort of brand. Which means they are comi from a tech and branding world instead of old world or specialty roasting. So you’re going to get more branding quality than ground up quality.
That being said, induction is pretty simple mechanically, and a rotating drum is pretty basic, so there isn’t a whole lot to break when things are working well for you. The company has a lot of potential. Just they’re still new and so they are an unknown. But home roaster machines aren’t really a competitive space yet, so perhaps in that regard they are quickly establishing a niche, but at a pretty high price. For $5K, espresso machines are better built and better performing, and coming from Centennial legacy companies sometimes, and they’re aren’t even pretending to be “pro”.
But in terms of your machine arriving DOA, I think you have a good chance of it arriving in good condition. And there is a lot to like about some of the changes they made. I used to have a faulty board that pulled extra power. It made the steps too big, but extra power is really useful. So hoping you get a good one 
I roasted on Hottop from 2001-2020. Great machines. As soon as I found out about the R1 I bought one and have no regret. I dont post much but read and learn from the community and am always interested and learning from their roast profiles.
My R1 had a IR sensor issue shortly after purchasing. Aillio provided great support and it operated flawlessly the remainder of its life. Perhaps Im weird or in the minority, but I cleaned and maintained my R1 religiously. I thought enough of the build quality to take pride in its maintenance. In my opinion, Its similar to firearms. A hurricane and 9.5ft of surge killed my R1. As soon as I have a space to continue my favorite hobby, Ill be ordering a R2 without hesitation.

Do we need to run the fan calibration on the R2 Pro?

No you don’t.
The air flow sensor measures the airflow and adjusts the motor / fan for the correct RPM.

How do we confirm if the airflow sensor is working correctly? Is there a way to switch over to RPM control if the airflow sensor faults?
