AtomStack A5 Pro won't boot


Hello everyone,

I have an AtomStack A5 Pro laser engraver and I am having a startup problem.

The machine powers on, but it does not boot correctly. The controller seems to start partially, but the laser is not operating normally. I am trying to determine whether this is a firmware issue or a hardware problem.

I have already checked the power supply, cables, and connections. I also tried restarting the machine multiple times.

Below is the information returned by the controller/GRBL:


configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

Could someone help me identify the controller, firmware version, and recommend the correct firmware if a reinstallation is necessary?

Thank you very much for your help.
Does anyone have the firmware for this machine? It is an AtomStack A5 Pro with a Laser32 A5 V1.0 controller board. I would like to update or reinstall the firmware because the machine is not booting correctly. Any help or firmware files would be greatly appreciated.

It looks like your machine is stuck in a boot loop. Where are you viewing the serial data?

Are you seeing this in LightBurn’s Console ?
