Print2Go

Build (Win/Linux)

A reasonably recent version of the Go compiler is required to build PrintAndGo (v1.25+) as September 2025

1. Clone project and cd to repo

   $ git clone https://github.com/chepo92/PrintAndGo.git
   $ cd PrintAndGo
   

2. Compile

   $ go build -o ./builds/PrintAndGo.exe .   # in case you are running in and building for Windows
   $ go build -o ./builds/PrintAndGo .       # in case you are running in and building for Linux
   

If you want to cross compile:

$ GOOS=linux GOARCH=amd64 go build -o ./builds/PrintAndGo-Linux . # Example for Linux 
$ CGO_ENABLED=0 GOARCH=arm64 go build -o ./builds/PrintAndGo-ARM64_RPI3 . # Example for a raspberry Pi 3
$ GOOS=linux GOARCH=mipsle GOMIPS=softfloat go build -o ./builds/PrintAndGo-MIPSle . # Example for MIPS Little Endian
$ GOOS=windows GOARCH=amd64  go build -o ./builds/PrintAndGo-Win64.exe . # Example for Windows 64 bit
$ GOOS=windows GOARCH=386  go build -o ./builds/PrintAndGo-Win32.exe . # Example for Windows 32 bit

Build with docker (usually for dev and cross compile)

1. Clone project and cd to repo

   $ git clone https://github.com/chepo92/PrintAndGo.git
   $ cd PrintAndGo
   

2. First build the docker image configured in the docker file, this will build the PrintAndGo code too docker build -t go-builder:1.0 .

3. After first time build, can be run

docker run --rm -v ./:/usr/src/app -w /usr/src/PrintAndGo -e GOOS=linux -e GOARCH=mips -e GOMIPS=softfloat go-builder:1.0 go build -v

1. After first run, can be re-started, with interactive terminal docker start -a -i go-builder

2. In the interactive terminal (IT), build the PrintAndGo project (use a the cross compile command from above if the case): go build -o ./builds/PrintAndGo .

3. Once build, copy files back to host (eg. after cross compile, get the binaries) docker cp go-builder:/app/builds/PrintAndGoLinux ./builds/PrintAndGoLinux

docker cp go-builder:/app/builds/ .

1. If you need to update the source, copy files from host to container (eg. developed new code and need to compile in docker), better to delete previous files if made a lot of changes In the container (IT), remove existing app files: cd /app/ && rm -r * Then in the host, copy to container: docker cp ./ go-builder:/app/ Then you can build (step 4) and copy back to host (step 5)

Cross compile

Go can be cross compiled Example for MIPS Little Endian GOOS=linux GOARCH=mipsle GOMIPS=softfloat go build .

1.Build docker image with updated files, no cache if anything changed (for dev), dockerfile and docker image can be modified with cross compile commands docker build --no-cache -t go-dev-linux-img:1.0 -f ./Dockerfile_builder .

Examples docker run --rm -v ./:/usr/src/app -w /usr/src/PrintAndGo -e GOOS=linux -e GOARCH=mips -e GOMIPS=softfloat go-builder-linux-img:1.0 go build -v

Examples docker run -d -it --name go-builder go-dev-linux-img:1.0

Virtual printer

There is a virtual printer code used for testing in /util from the original Takoprint repo.

Webcam

Webcam support is WIP, but should mostly work - as long as your webcam shows up on /dev/video0.

Note that certain webcams are extremely power hungry and can cause stability issues on RBPI hardware:

The excessive power draw of some webcams can cause issues to the USB controller, resulting in ‘lost gcode’ replies which will cause the print to stall. This is not a bug in PrintAndGo: If you suffer from this issue, get a better power supply or/and replace your webcam (or find other ways to feed power to it, like using an active USB hub).

Note that PrintAndGo has an escape hatch for stalled prints: Sending a USR1 signal to PrintAndGo TTY subprocess should resume the print in most cases:

$ ps -ef|grep :serial-pipe   # first, find the subprocess
takopri+   351   301  0 09:01 ?        00:00:00 PrintAndGo -tty /dev/ttyUSB0 -baud 115200 :serial-pipe
$ kill -USR1 351  # send SIGUSR1
