I have the spindle plug in folder with the 3 files and the only code changes Ive made are by adding define VFDENABLE 1 // Set to 1 or 2 for Huanyang VFD spindle. I see that there’s an Marlin feature request that’s just to access the UART or SPI for someone who wants to talk to temperature sensors via modbus, and they’re talking about using a separate microcontroller to handle the modbus. It is possible to connect and configure the spindle VFD to the mach3 via an RS485 communication and protocol. Ok, so I have the latest GrblHAL up and running and active without spindle, when attempting to enable RS485 control, my sender can see the Teensy but I cannot get communication. I mean, it’s probably doable, and if you’ve got a decent processor, it could probably handle it, but it wouldn’t be simple. ![]() There’s a lot going on in there, more than you probably want your CNC controller handling. Took a quick dip into modbus, and you almost need a separate microcontroller just to handle the modbus communications. ![]() Does your spindle frequency inverter (BTW, I’m just parroting your terms back, I honestly don’t know what a frequency inverter actually is) only talk Modbus, or is there another way you can control it? Does it take a PWM signal? We understand PWM signals. Hoo-boy! OK, you’re talking about implementing a protocol you don’t really know.
