Firmware web builder stm32 nit working

[Jamilgalau]

hello terje i build firmware via STM32 bluepill web builder, i have connected EStop or Reset, Cycle Start, and Feed Hold to ground but grbl firmware can't be run on openbuilds, ugs, and io sender, last year i did it and it worked. thx

It works for me (CNC3040), default options:

The port shows up when you connect the board? And can you connect to the port with the sender?

Thank you for the latest firmware update, it can work well and run smoothly on UGS, G Sender, and IO Sender, but unfortunately it cannot be used on the OpenBuilds controller, there are error messages alarm 2 and 9

[terjeio]

Alarm 2 and 9 is related to soft limits and homing respectively. Error 2 and 9 is related to bad comms and alarm beeing active when sending gcode to the controller. So perhaps disable soft limits and ty again?

can't connect with openbuilds from the start, I use STM32 Blue Pill, maybe you can try it...but it's normal in almost all gcode senders..I'm used to opnbuilds controller

If you power up the controller and connect with a terminal (like puTTY) what is the response when you send a ? to get a real time report?
