Can I send a compiled F103C8T6 HEX file? Email 459429772@qq.com

[hankecnc]

Hello, I am from China, I am a cnc enthusiast, my job is a machining center master, cnc is a hobby, I used this firmware from https://github.com/robomechs/6-AXIS-USBCNC- GRBL, I saw your source code today. I downloaded the source code to the linux system, installed arm-none gcc, and used the make command to compile, but after downloading, I connected the computer through the ch340g serial port module and sent $$ without any response, and then I tried to uncomment them separately in the boardmap_bluepill.h file//Setup COM pins (must match selected COM port) //#define RX_BIT 10 //#define TX_BIT 9 //#define RX_PORT A //#define TX_PORT A

And //#define COM_PORT 1 //#define TX_BIT 9 //#define TX_PORT A //#define RX_BIT 10 //#define RX_PORT A There is no response after compiling and downloading. I don’t know much about C++ and microcontrollers. Can you send me a HEX file of F103C8T6 to 459429772@qq.com, and tell me whether the communication method is serial or USB virtual serial

I there. I just compiled the default version of µCNC (3 axis cartesian machine on bluepill with USB virtual COM port). Try it and tell me if it works..

[hankecnc]

I did not see any files available for download on this page,

I used this firmware earlier https://github.com/robomechs/6-AXIS-USBCNC-GRBL He works very well, I would like to try your firmware, but the process is not smooth,

[Paciente8159]

I sent it to your e-mail. I've also added the compiled hex in the release v1.1.0 (just scroll to the bottom and download the hex for the bluepill). Thanks.

[hankecnc]

Thank you, I downloaded the uCNC-bluepill-usb.hex file of this page https://github.com/Paciente8159/uCNC/releases/tag/v1.1.0 to the blue f103c8t6 development board, connected via USB, the computer can The STM virtual serial port was recognized, but I did not get any reply when sending the $$ command through the serial port software, and then tried to connect the serial port PA9 and PA10 through the CH340 module, but there was no reply.

Nothing happens when using other grbl-related software such as Candle

[Paciente8159]

This compilation uses the bluebill built in USB. Using and external serial cable doesn't work. Also try this: Short PINS B5 and B6 to ground before plugin in the USB cable. These pins are the hard reset and feed hold (negative logic). If B5 is left ungrounded the µCNC will be in failsafe mode and will not respond to any command. All limit switches and probe are also in negative logic as a safety measure (in case any fault or forgotten connection it will trigger the alarm/event) Then µCNC will reply to your commands

EDIT!!! You can invert the working logic of the triggers/switches without the need to recompile the code. Just read about commands $5 and $7 here. But to do this the first time after you upload the firmware (if you did not modified the firmware config file) , PIN B5 must be shorted to prevent failsafe mode.

[hankecnc]

Thank you very much for your patient guidance, I will follow your prompts PINS B5 and B6 are grounded and have gotten a reply, thank you very much

[Paciente8159]

Your welcome. And thanks for trying out µCNC. Any problem please report and I'll get to it ASAP. I'll keep this issue open for a few more days in case you have any doubt.

I am willing to try new things. What host computer do you use to operate uCNC?

Although uCNC can connect to the serial port software normally, it cannot use Candle2 https://github.com/Schildkroet/Candle2 The host computer communication on this page, click on the connection, no response, another laser drawing software is also, I guess whether it is a handshake protocol Has it changed? Because I am not good at programming, I can't solve this problem. Candle2 is excellent as a grbl host computer, and I don't want to give it up.

[Paciente8159]

I'm using OpenCNCPilot. I like it alot and it has a very clean and simple interface. I'll try Candle2 to see if I have any problems.

[Paciente8159]

I've tested Candle2 and the original Candle. It seems to have been locked to use Grbl firmware. If I modify µCNC startup message to output: Grbl 1.1.1 ['$' for help] Candle2 and the original Candle both start communicating with µCNC. To modify the startup message go to the grbl_interface.h file and modify the MSG_STARTUP_START from #define MSG_STARTUP_START "uCNC " to #define MSG_STARTUP_START "Grbl " Recompile the code and upload and it starts working.

[Paciente8159]

Since the problem was solved I'm closing the issue. In a near future release an option to emulate Grbl startup message will be added to improve software compatibility.
