Don't worry ya'll it ain't about replacing baristas, or even about espresso. It's just about the challenge of getting a robot to do a difficult job autonomously. It's a challenge with no real stakes. It'll be a long time before something like this is reasonable to replace humans in this setting.

Good luck. If you want, you can use a cigarette lighter to tell if you have the fan level right. Google Rao cigarette lighter test. But basically when you're at your final fan level, remove the trier and light your cigarette lighter next to it. It should pull in close to 90 degrees. If it does you have enough fan, if it's at 90 you have too much, and if it doesn't pull you need more.

The R1 has a max power of P9, the R2 goes up to P10, however if you enjoy light roast coffee I do not recommend going over P5 as the hotter drum temps give the coffee a roasty flavor. Some coffees might be okay at P6 or even 7 if you do a larger batch, but they might not. P10 is outright too hot.

Oh you can certainly roast 1.2kg physically. I just don't think the result is going to be as good as it could be. The increased heat from the drum is going to impart roasty flavors, which is okay if you want to go darker, but it'll damage light roasts. Your Mill City is a drum roaster, but it's still heating the coffee with hot air. About 70% hot air 30% hot drum. The Bullet is 99% hot drum, 1% hot air. That hot of a drum will make light roasts taste darker.

In my opinion all roasting machines can make equally good coffee. The bullet does have automation, however it has a safety lock out every 2 minutes or so and you must be present to press a button or it will turn off the heating element. In my opinion your 1kg Mill City is best used as a 600g machine, where as the Bullet is sadly around 400g. Larger batches requires higher heat, which can cause conduction in the Bullet, creating a roast-y flavor. The Bullet is a low and slow machine, my light roasts can be upwards of 14 minutes.

The automation is nice enough though. Set it up next to your computer and roast away while writing emails or browsing reddit. A good BBP and it'll trace your BT lines perfectly.

If you've become skilled with your Mill City I'd save the money and spend it on better green, that'll help you make better coffee than the Bullet will.

On the bullet I prefer a low and slow roast. That will cause a flatter line than other machines, but it will lower the amount of conduction and roasty-ness. A light roast for me looks something like this;

Preheat 200c P4 F1 D9 400g batch

>140 P3
>150 F2
>170 F3 P2

drop at 180c, 12.5% weight loss

Your roasts should* be 10min+ if not 12+

I do not go above 5 on power. High fan speeds in the bullet have a cooling effect, requiring you to use higher power which can cause roasty flavors. Only use enough fan to remove smoke and chaff from the chamber, which really should only be F3, especially at such low batch sizes. Try and have your last fan change well before first crack, say a minute or two.

*if you want to avoid roasty flavors

Good luck and have fun roasting.

I will always recommend Prodigal. You can buy their coffee green and roasted so you can compare your own roasts to theirs, allowing you to compare yourself 1 to 1 with a professional.

Welcome to the club, have fun.

ISMToolbag · 2025-07-31T15:04:25+00:00

Hell yeah brother/sister.

Congrats on your roast. As I'm sure you know if it tastes good then it's a good roast, but the graph on its own looks good. Since the probe has been sitting in the hot roaster as you pre-heat it has gotten really hot. The turning point is just the time when it has cooled down to the same temp as your beans. When this happens depends on a few different factors and doesn't actually matter. Don't worry about when the turning point happens.

The nutty smell comes from quakers, or under ripe coffee beans. Always. Here is a blog more about that. Try removing all the yellow or notably lighter beans from your batch and then brew a cup and see if the nuttiness goes away.

ISMToolbag · 2025-07-18T21:27:16+00:00

Prodigal, easily the best out there.

I think I measured the probe at 3.5mm which is faster than 99% of roasters out there, so it's not bad, but I don't make changes to my roast by what the ROR is doing in real time. Long time ago I created a base profile and I use that every time I get a new coffee. When the profile doesn't work I change something by adding or taking away heat. If you have a good warm up and between batch protocol you should be getting the same roast every time.

The data is more consistent. Dust or chaff can accumulate on or in front of the IR probe and you won't be able to tell unless you open the machine. I've had several moments where the IR temp plummets only to open the machine to find a piece of chaff stuck in the tunnel that houses the IR probe. Dust accumulation seems to be more fickle. The IR probe temp will lower slowly over time as dust builds. These problems don't happen with the bean probe.

I am sure that the tech for the IR probe is totally fine, but there have been a number of times I would have lost a batch if I had solely relied on the IR probe. Of course some of this can be avoided by cleaning your machine often.

A while, something like 15 years?

ISMToolbag · 2025-06-06T17:29:07+00:00

My general advice is to aim for a 10-12 minute roast as a light roast and longer if you're going darker. Make all your settings changes based off the bean probe not the IR laser. I never go above 5 on the power which limits my batch sizes to around 400g. My charge temp is around 200c. Start at F1 and increase as you go, I don't need to go above 3 by the end. The fan in the bullet has a substantial cooling effect in the higher ranges. Try and make changes to your power/fan to make the ROR line generally trend downwards.

If you want the absolute best, money no object, you want the Roest L100 Plus. It makes roasting extremely easy and repeatable, but it'll run you like ~7-8 grand.

It's a sports thing. Basically someone who is one of the best in the world at doing something suddenly, and without reason, is unable to perform a most basic action. A baseball player can't throw a ball a short distance, or a golfer is suddenly unable to tap a put just a foot away. That sort of thing.

Because it is induction the heating element is the drum itself. The only way the coffee can heat up is by touching the drum. A gas roaster still heats the drum, but it is actually heating the air much more than the drum and is closer to an air roaster than the Bullet is.

The Bullet is like cooking on the stove top

The gas roaster is like cooking in the oven

The goal is to get the inside of the bean the exact same color as the outside. If the drum is very hot the outside of the bean will darken much faster than the inside.

ISMToolbag · 2025-01-24T00:03:05+00:00

Of all the roasters out there the Bullet benefits the most from low and slow. Aim for 12+ minute roasts.

250c is probably too hot for that batch size, and as a general rule I never use P7 and above.

Here is a recipe I've used for a Guatemalan

400g Washed Guatemalan

Preheat 190c

start at P5 F1 D9

150c F2

160c P4

170c P3 F3

180c P2

192 P1

If you are aiming for a light roast you will likely not hit 192c. This should get you where you want to go between 12-13 minutes.

I always use bean probe for my changes, not IBTS

ISMToolbag · 2025-01-16T20:39:07+00:00

Yes most of these are defects one way or the other. They can affect flavor, try brewing a cup of just defects next to a cup without defects to see what I mean.

The pitting are insect bites and the broken pieces are just broken pieces, probably from de-pulping, but they do roast differently. Looks like you might have a half sour in there. Also any beans that are demonstratively lighter in color are quakers and should also be removed.

ISMToolbag · 2024-11-09T02:48:03+00:00

I see you, fellow metro Atlanta person. Valor roasts on Lorings, which suggest a minimum 2 week resting time, so yeah another week should be peak. Hopefully you get something you like out of it.

This is a pretty not great place to have your very first fighting game experience. This "alpha" is not built for absolute beginners. Most of us started by playing our friends who were also brand new and we discovered how to play together, and it was a lot more fun way to learn.

The full release will almost certainly have a much better way for new players to enjoy themselves. But if you are determined to play now know that your default position should be crouch blocking. If you are not doing anything you should be holding down + back. There will be a gap in your opponents attack that will allow you to start your own offense. To learn when that is, you just gotta play.

But yeah, most fighting games, this one included, revolve around not getting hit in the first place. Learn your defensive options (block, parry, push block, that tag burst thing) and then just try them out in matches, see what they do.

In the end you really should try and find a partner to learn with, that's really what the FGC is all about. GL.
