Alternative firmware for CNC3018 offline controller

Рет қаралды 28,397

2 жыл бұрын

This is an alternative firmware for a CNC Offline Controller that is frequently sold with 3018-type CNC machines.
The controller has an STM32F103C8 MCU, 128x64 two-color OLED display, SD card slot and USB socket.
The firmware uses Arduino framework to make it usable for DIYers and hackers. Firmware is supposed to talk to any GRBL-enabled CNC machine, including lasers. At the moment the firmware allows jogging, spindle/laser control and (mostly) running jobs from SD card.
Project description, source code, build&install instructions:
github.com/positron96/cnc3018...
Sister project (an ESP32 DIY controller) that shares a lot of source code:
github.com/positron96/ESP32_C...

I LOVE that you can change workspaces! This was a bit deficit on the original controler firmware. I NEED to give this a try. I may make a hardware clip for the 4-pin connection rather than soldering a connection, so that I can put it back into the original case cleanly.

This is so great, wish it worked for the newer, 1.8 inch color display versions...

Thank you! I don't have newer version, unfortunately

Just FYI: I bought a CNC3018 pro a year ago and the included a newer offline controller, which is based on an esp32. I suppose this would open up wifi functionality.

Yes indeed! I've made a esp32-based pendant (also on youtube), stumbled upon too high current consumption for the CNC controller to handle

What program do you use for flashing the original hex?, I flashed your firmware but it doesn't send any command to the cnc board

@osmanpasha_diy 2 жыл бұрын

I've used j-link and openocd successfully. Does the firmware show anything on the display?

@Vinpinto 2 жыл бұрын

@@osmanpasha_diy Yes it does show the interface, I put a serial probe in tx rx terminals, the behavior is as follows: after the firts $I sent by the offline controller, the machine responses with [VER:1.1f.20170801:] [OPT:V,15,128] ok the offline controller understands the response and sets the baudrate as 115200 correctly after that the ofline controller only shows the machine as X idle or sometimes Lockpad Idle, but no further comand comes out of the offline controller, not with a SD card file, not with the DRO, or any other entry on the menu

Heya! I recently got a 3018 Pro CNC that come with a newer board with WIFI function built in... Was just wondering if youd played with it as Ive tried to connect to the controller through software like UGS and LaserGRBL but they say connection refused. Yet the controls are identical in how they move the machine.... I want to see if some people are interested in trying to build a custom firmware that allows this kinda stuff?

@osmanpasha_diy 2 ай бұрын

Hi! I've heard people say these controllers have WiFi capabilities nowadays, this means they are completely different from what I have here. So no, I haven't played with the new ones. But LaserGRBl at least should work with WiFi as I understand

@@osmanpasha_diy fair enough.. its interesting cos neither connects, they both just say connection refused... my guess is the board doesnt allow connections outside of your browser but idk aha

you can use st-link v2 with OpenOCD and PlatformIO. My project has settings to upload via OpenOCD. I don't know how to upload with St-Link Utility. Also you didn't answer how you've built the hex. If you did it with PlatformIO, then you have everything to flash.

Hello and thank you very much! What do you mean by incomplete? As you can see from the video, the buttons are fully handled in firmware (so you can find the pins in code), and in the schematic on GitHub the MCU pins where buttons are connected are marked.

@@luisalonso9987 Hola and thank you! Yes, 8 keys go directly to MCU pins. On schematic, they are named BT_U, BT_D, BT_CENTER, etc. SSD1306 display should work, though if it says "4 pins" is probably an I2C module. On the controller it is wired via SPI, so I' would look for SPI display for compatibility.

My offline controller could only do simple. Not 3d carve. Idk maybe it was just mine. Looked just like that one

@osmanpasha_diy Ай бұрын

Hi, I think that's expected. To do complex tasks, you would need a g-code file, and controller can work with file of any complexity, 3d carve and anything.
