Hello Dan,
you are totally right : WHY ?
– When I started I knew nothing about writing an apk for Android.
– And we needed “additional hardware” to make a stand alone CNC, my first goal.
Now we need an SD card reader, a Bluetooth module and something everybody has always in his pocket. (but it still works with a PC or the “additional hardware”) .

I tried again to make a pull request without success. (don’t say I’m dumb : I know)
I would have liked to be one of your contributors but I think my codes will fall in limbo.
( or you could fork them … Up to you)

I received my new toy today : ESP32. Will be out of the (marvelous) world of CNCs for a while.
Best regards,

Hello Dan, I didn’t receive a notification by mail and just readed your last message.
I’ll try again to make a pull request tomorrow. Again sorry…

The Android APK is finished. Tested on a Motorola G3 and a Wiko Y60.
The new code for the MEGA , the source code (.aia) and the apk Android are on the net.
https://github.com/wolf8012/Control-a-CNC-by-Android
Works with the additional hardware as before when unpaired and with a smartphone.

It was fun writing it, and I learned a lot (my first apk Android, oops).
Untested : the compatibility with a RAMPS. But it should work.
the Bluetooth Rx is Y-MIN on the RAMPS (don’t forget an attenuator),
the Bluetooth Tx is Y-MAX on the RAMPS,
and the STATE pin of Bluetooth ( to make a clean unpaired ) is D17 and also 23 on the RAMPS.

Best regards,

Hello Dan,
I tried to send a pull request and failed… Sorry.
My code is downloadable : https://github.com/wolf8012/GcodeCNC_SD_OLED_JOYSTICK

I am writing an Android app for this code.
( Without previous experience in MIT App Inventor)
The goal is to learn and reduce the hardware.
90% is done. ( Ninety-ninety rule … )

I’ll get back when it is done.
Best regards,

Hello Dan,

I tried to send a pull request through github but it seems that it concerns the changes to 1 code.
( the SD card is added to a mix of 2 of your codes… )

Always in the idea of a stand alone machine I have added since Xmas a read and save of (4) Gcode names of files on the SD card.
While adding an Oled128x64 ( an LCD2004 is big and current hungry) and a joystick it will be possible to choose the file to run and display the “line of total lines” processed .
I’ll get back when it is done.
Best regards,
