Hello, I built an mpcnc with the SKR Pro V 1.2 and the TFT35-E3 V 3.0. With the display I can control the CNC and everything works, but I want to control my cnc directly from the laptop now, and here I can’t get any further. None of my laptops can find the usb port of the Mpcnc, so that I can program the control in estlcam. I have already flashed the board with the (V1CNC_SkrPro_Dual_2209-2.1.1.zip) and tried to remove the screen
Neither worked. What could be the reason for this?
Some possibilities:
- The computer to SKR USB cable needs to run from the computer to the square USB port on the SKR pro. Any other cable configuration won’t work. The display being plugged into the SKR has nothing to do with whether the computer can connect. The display uses different ports to talk to the SKR.
- When you plug the SKR into the computer, a USB port needs to appear on your computer. If you have a windows computer, there need to be USB drivers installed for that connection to work. To troubleshoot this better we would need to know what OS you’re using on your computers.
- If the port enumerates but your sender isn’t aware of the port to use, it won’t work. I suspect this isn’t your problem- but it would be good to know what sender you want to use on your computers.
Also Estlcam can’t control the SKR board. It takes a special control board to use that. 99% of us just use Estlcam for CAM not for control

When you say it doesn’t connect, can you be more specific?
What are you using to “control” the CNC, and what do you mean by “control”?
As mentioned above, EstlCAM doesn’t work on a SKR board for control, but is great for CAM (creating g-code). You need to use the SD card (either in the SKR or in the LCD Screen) to run g-code programs.
If you are trying to do simple moves like you do from the LCD screen, then a program like Pronterface or Repetier Host will be needed. Not sure, but you may need to be in Marlin mode rather than Touch Screen mode for this to work (hold the knob on the SKR for a few seconds)
What Jonathan says. You need an OpenCNCShield or CNCShield (or similar) with an Arduino Mega or Nano to use the Controller portion of Estlcam. @RegPye and I are the only ones that currently use one of those boards, because we are extra fabulous 
and not like the other kids.
