I’m sorry there are no drawings.

oh, 2. is in desc :D

Hi! Thank you! 1- Custom made with a local welder 2- It varies a lot. I made a second unit and the PID settings were quite different, but on this one I’m using P-4; i-0.22; d-108. Started with D=0, but the more I kept raising it, the better it followed the ROR. With the D higher than 60 it was already good, but now it follows much better than when I made this video

Unfortunately I understand absolutely nothing about this programming part. I needed something more plug an play to make things work, so I bought this ready to go module I’m using. Just screwed the thermocouple, and connected to a ssr to control the roaster. The guy sent me some pre configured settings and I’ve tried to fine tune the pid values on trial and error. Nice work btw, really cool MODs but what you did there it's a bit over my capacities hehehe

Ha! Actually the Arduino Nano and Max6675 setup is much more easier than your setup. I can literally share with you the program, you only need to download it to the Arduino Nano, it takes less than 10 seconds, connect 5 wires, that’s all you need. Anyway, I like your design more than mine….//

The dimmer is actually from the blower itself. It’s a pet dryer/blower so it came with variable speed built in. It’s just one potentiometer knob. The heater is controlled via a Fotek 40da ssr, it goes to the Autonics pid controller and to a module that connects to artisan, and there’s a switch where I can swap which one “commands” the ssr.

@@ifr3293 ok, i thought that you control faN speed via artisan as well

I really wanted that, but this module I found to buy locally was made to control drum roasters only, so it’s incapable of controlling the air yet, that would be awesome. Maybe one day I’ll try that other tc4+ module, but I would have to buy everything ready, I have no idea how to assemble or program it. Maybe someday

@@ifr3293 random fire ssr and zero crossing detector is doing job fine, mine is working as expected, just dont buy robodyn as its a crap

@@ifr3293 Check out Greencardigan on youtube for programing 👍

Could be WhatsApp or email

Ok. Let me know how to reach you or where to find your information

I have no idea because there were lots of tests, things that went wrong and had to be adjusted and re made, I’ve tried more than 8 heating elements when I was building it, but probably something around U$1200. Im building another one and it’ll probably be quite less than that, with lots of improvements on aesthetics and size, but with the exact same functionality, and trying to get a larger batch capacity

The bake-a-round is too small and very limited in terms of volume. I think he mentions this in one of his videos, that this is a major thing that he would have done differently today. With that in mind, this glass is actually custom made. I found a company that makes test-tubes here where I live and asked them to build a 120mm diameter borosilicate tube. This way I managed to roast 800g at full power and 650g Artisan controlled. I’m about to start another build with a 150mm glass hoping to reach 1kg. The funnels are stainless steel and are also custom made.

@@ifr3293 look up Alex Campbell's roaster if you haven't. Perhaps for a small production roster a bake-a-round is too small which it sounds like is what you might be doing. I can't imagine you need to roast a whole kilogram at a time for personal use. Haven't seen the video where he talked about the parts. I'd like to know where to get those funnels made.

@@josephplaugher7324 I found a local welder who made them for me. I’ve watched and read about every home roasters I found online before building mine. His roaster is awesome , I think he commented that about he pyrex on a forum maybe, don’t remember exactly where.

Hi, I’m sorry but there are no plans. I planned while building it, and kept changing a lot during the process. The funnels are the only custom made parts I ordered.

Yes. There’s a switch that changes between two options. I can use a manual PID controller Autonics TC4S where I select the ET temperature manually, or the Artisan software to control the heating element following a background curve.

Yes I’d like to know too.

It’s a heat gun heating element rewired for 4kW. It’s inside a stainless steel tube. The path is blower > stainless tube with the heater > lower funnel. You can see the thermocouple Im using as ET. The tip of the heating element is less than an inch below that. I just ordered a new type of heating element that I think will be more efficient, will heat the air better and the air will go through more freely with less drag. I don’t know how’s it called but there are some examples below resitermo.com.br/mica.htm frantecmaquinas.com.br/wp/wp-content/uploads/2020/03/WhatsApp-Image-2020-03-02-at-12.57.22-1.jpeg cdn.awsli.com.br/300x300/1279/1279490/produto/74512382/0591fd5768.jpg

Hi, thank you! I didn’t write about this build yet, but feel free to ask any questions about it. If you have any major questions we could talk on WhatsApp or something. Cheers!

@@ifr3293 Hello. It seems to me that the TC4S has no modbus connection. Am I wrong ? how did you connect artisan with heater and thermocouple? Sorry for english i use translator. greetings

@@niepamietam Hi! The TC4S is just a backup to control the heater manually if Artisan crashes. I’m using a modbus interface “Plugin Roast”. Their website is on the description.

Hi! Send them an email (pluginroast@gmail.com). They also use WhatsApp, you can send them a message that way too.

@@ifr3293 Thank you.
