xPro V5 vs CNC shield vs others?
The BTT SKR is a 3D printer controller using a 32-bit LPC (Arm, baseically) micro, so it'll easily support 4 axes and have plenty of leftover power/expandabilty. The main gotcha could be spindle control, but... hm, yeah, the source indicates that they just use a heater MOSFET for spindle PWM, so it's not going to be much different from a stock 3018 controller.

Is it possible to delete the boot loader on a SKR 3 EZ?
Take a look at https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader -- it may help. It's not only for the larger boards.

SKR 3 EZ Bootloader FW
However, I couldn't manage to find the original bootloader for this chip. I found this : https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader which is very interesting for many older BTT controllers, but not the SKR 3 EZ.

Bootloader broken on 4.2.7 board?
If you want to investigate, you might start by looking at https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader

Upgrade fw without sdcard ?!
The only other way is to use a little programmer such as an ST-Link, which looks similar to but is different from the little USBasp programmers that can be used for 8-bit boards. An ST-Link can flash firmware directly, but it's not as simple as using the SD card. See, for example, https://www.youtube.com/watch?v=7O_ZOdnM0SU and https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader

My micro sd card reader on my btt seems to be broken can I use a usb isp to update the firmware instead?
For LPC based boards this may help. It seems to allow flash over USB.

SKR Mini E3 v2.0 doesn't update its firmware even if the firmware.bin change to firmware.cur
It doesn't sound like an EEPROM fault, because that only affects various settings, not what functions and codes it supports. It sounds like something is wrong with the bootloader, eg it's reading the firmware file but not storing it. If nothing else works, is it worth getting a little STLink in-system programmer and reinstalling the bootloader and firmware completely? There's a link at https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader which should be helpful if you want to try that.

I think I bricked my skr 1.4 turbo
(If all else fails, you can try reflashing the bootloader - something on this page may help you.)

SKR V1.4T AGAIN!
Technically, it's possible to use a programmer to update the firmware, and I've seen descriptions of how to do that with various small programmers. Here's an example. Perhaps a google search will find more information, given that it does exist. People have used that technique to read and (re)load bootloaders and firmware.
