Delta MS300 VFD, RS485, RPI4, QTdragon, getting it to work

Yesterday I've made a teamviewer connection between my home-pc and my cnc-machine (that's in a cold space), that gave me an nice environment to test thing. And... mb2hal is working!  I've attached my mb2hal config. I'm not happy with the naming yet. I expected all names like mb2hal.spindle.[pin-name]. But only the first transaction is named that way.

But...... I have EMI problems I think, When I stop my spindle, usb-devices often stops working.
My PI is connected to my Delta MS300 via usb, using the inbuild rs485 converter of the VFD. What shell I do? Use mesa_modbus and eliminated the use of a usb-cable? Do I need another firmware to use mesa_modbus on my 7c80? I probably have to put my 7c80/PI4 in a steel box too... I'll ask this kind of things on the printnc-discord...

The firmware's for the 7c80 doesn't seam to have pktUart enabled. I've asked Mesa for help. Compiling the mesa_modbus driver was the easy part
 

It looks like I've solved my electrical problems, changed some cables and used some ferrite cores.

@PCW: Can you help me getting PktUART working on my 7c80? There is no firmware on the mesa-website that supports PktUART...

Hi Calysto,I use the same components as you. RPI4 on 7c80 and MS300.
I am currently using the PWM terminal to control the spindle. Can you share the whole configs folder with me?
This will help me a lot to understand by comparing the differences.

Here it is. I use 2.9.2. The joypad does not work correctly yet. Where you are looking for should be in the "4_QT_spindle", "9_QT_postgui" and "mb2hal_MS300" files.

Happy to hear I'm not the only one with this setup

I've connected my VFD with an usb cable to my PI. I hope there will be Pktuart firmware for the 7c80, so we can use the RS422 connector.

If you have questions, let me know....
