ReflowMaster2000plus deluxe PRO

Welcome fellow! You came to the right place to find out more about the awesome Reflowmaster2000plus Deluxe pro.


You might want to go straight to our github repo of awesomeness

The incredible Reflowmaster2000plus Deluxe PRO is a reflow controller for the hackerspace afficionado. It provides a light interface to measure heat and control some 220V device powersupply. You can interface this with anything that is able to bang some GPIOs, but we supply you with a simple arduino sketch to get going quickly. All the processing is done in the python based PID controller.

Schema and PCB

Of course the Kicad blueprints for the unbelievable ReflowMaster 2000+ Deluxe pro are available also on our fine github account.

btw, we <3 kicad!!!5!

here's some fine images to marvel at:

PID controller frontend

note: on debian 9, it works if you install the dependency pypid from source and the others via apt:
git clone https://github.com/drogenlied/pypid.git
cd pypid && sudo python setup.py install
sudo apt install python-{nose,numpy,serial,scipy,tk,aubio,matplotlib}

All the control logic is implemented in a python client, that you can start by running

python reflowcntrl.py /dev/ttyUSB0

In case the arduino/other microcontroller driving the wonderful reflow master 2000 plus deluxe pro is indeed connected to /dev/ttyUSB0, this should provide you with a CLI prompt, which helpfully provides a `man` command.


man: provides help on commands
bake: starts the baking process
stop: stops the baking process
disp in: displays the currently measured temperature
spt: displays the current value of the target temperature
pwr: displays the currently driven power
quit: very useful in case you're done baking smd.

The nice display show-cased in screenshots under the controller controller accuracy section , is shown only after issuing a bake command. shows up at the beginning, displaying the loaded profile in blue, so you can verify it before issuing a bake command.

... there's other commands for fine-tuning the PID params, i guess they should be documented too.

PID controller accuracy

The accuracy of the amazing Reflowmaster 2000+ deluxe PRO is world famous, while average solder paste works in the ball park of 30 degrees thresholds, the fantastic Reflowmaster2000+ Deluxe pro manages within 1-2 degrees accuracy, see our measurements for yourself:
