Operate without an SD Card

Quick question, it is possible to operate the LR v4 without an SD Card. The machine will not recognize the card I have, a 32mg Class 4 card?
I ordered 2 from Ryan but am itching to draw myself a crown.

It’s not recommended.

The Jackpot can have gcode stored on the “drive” space on the ESP32, that ought to be enough to load and run the crown gcode.

Repetier host can manage sending to the SKR Pro (and maybe the Jackpot) over USB. I wouldn’t necessarily risk expensive material to that setup myself, but people have done it.

A Raspberry Pi running OctoPrint (Marlin) or cnc.js (FluidNC) can be a solid solution, more than temporary.

Getting the crown done is a good step.

Before that though, make sure that your SD card is formatted in FAT32 format, or maybe ex-FAT. 32G should be okay in FAT32 though. Windows wants to format in NTFS and Mac wants it’s own filesysten, neither of which will work with the CNC.

I have formatted it in Windows to FAT32 and exFAT32. I also downloaded SD Card Formatter and used it, all have failed. I have a couple ordered so will just have to wait until they get here.
Thank you for the help

FluidNC’s libraries do not support exFAT file system.

The card has to be an SPI capable SD card (Not all are!), and formatted with FAT32.
