Hey guys,

I also recently bought a 3018 CNC. An offline controller was also included. But this one has an STM32F103RBT6. That means I shouldn't try this firmware, right?

regards maxl95

Hi. This looks like a controller with a colored TFT display, which is totally different from the OLED display in the controller I have. So, I'm afraid, my firmware will not work with this board.

Thank you for your quick response. Yes, you're right, it has a colored display. The firmware on the Controller is very bad. I thought I could improve it with your firmware. Unfortunately the read-out protection is activated. So I can't make a backup and make firmware myself.

Hello Max195.. I have the same as yours... I bricked mine, trying to upload the firmware... from positron Any chance that I could have the firmware for it.. ?? I first read it though, but When i read it with ST-linkv2 the memory starts at 0x08000000 for 0x3F54 Bytes It is a lot less bytes.. than the original.hex from positron. Can you try to read it.. The SW settings is slow speed at 480kHz and the it connects OK ! but only reading from that adress Tnx 4 help JP

I t can be read, probably I read too little... i had to read the full data range, but did not.. I used a white ST-LINK V2 JP

@Jempiken. @maxl95 guys have you any updates with that? May be we should try to make some branch and start to do from scratch?
