Operation
• After placing different materials, you need to use a multi-level fixed focus block to
adjust the height of the laser module.
• For basic parameter settings of the laser engraving device, please refer to the file in
the TF card titled "GRBL Configuration Parameters."
• Firmware Upgrade:
o You can download the latest firmware version from:
https://www.crealitycloud.cn/en/software-firmware/other?type=16
o First, back up the files from the original TF card to your computer. Then clear
the TF card to avoid lags during the update. Save the newly downloaded BIN
file to the first-level directory of the TF card.
