not needed, AWG-ACTO-V1, actuator/motor controller card, Afache

The markings AWG-ACTO-V1 and 170324 are clearly visible on the PCB. The connections and electronics are particularly telling: it features INPUT, OUTPUT, V+ / V−, as well as A+ A− B+ B− labels. A+/A− and B+/B− are typically two-phase stepper motor coil terminals, and the board also contains high-power driver/power supply components. Additionally, an Ethernet/RJ45 interface is visible.

Based on this, I would define its function as follows:

AWG-ACTO-V1 – AFACHE actuator / stepper motor controller board

As a product name in English:

AWG-ACTO-V1, AFACHE actuator and stepper motor controller board

or, more cautiously:

AWG-ACTO-V1, actuator controller board, AFACHE laser system

The 170324 is likely a PCB/version date of 2017-03-24, but this cannot be stated with certainty from the label alone.

An important difference compared to the previous one: the HSS_C02 / AFACHEBA120 looks like a central controller/I/O PCB with extensive CAN/RS232 communication, whereas this AWG-ACTO-V1 may be a sub-controller used to drive a specific mechanical axis/actuator.

I also searched the public web for the exact AWG-ACTO-V1 identifier, but no usable manufacturer documentation or parts list can be found for it. For this reason, I would not state with 100% certainty exactly which axis (laser head, positioning carriage, etc.) it moves.

The most robust designation at present: AWG-ACTO-V1, AFACHE actuator / stepper motor controller board.
