pattarom As far as I know, someone has successfully cut 6 millimeters of plywood. It needs a lot of passes and a nozzle with compressed air that blows over the cut, otherwise, after a few passes, the wood starts to burn. Atomstack has recently started to sell his mini compressor that comes with adapters for all models of laser cutters and a cutting bed to place below the piece to cut to avoid burning the underneath table.

pattarom No, it is a single channel.

pattarom You cannot restore original firmware without disassemble the plug invalidating the warranty. Also original firmware is not available for download.

pattarom Yes, you can connect to Tuya App and you can connect from Internet to the device.

pattarom Usually any NEMA 17 motor should run flawless. You only must check the connector pins position, because pins position is not a standard between manufaturers. If old motor is not burn, you can use a multimeter set in ohm measurement, to discover where motor coils are connected. To find a coil check what pins give continuity (or zero ohm). Compare the position of the old motor with the new one and modify the cable accordingly, changing the position of the wires in the connector. If the motor rotate in reverse, simply swap, between them, the wires of one of the coils (pratically invert the polarity of one of the two coils).

pattarom Looking into manufacturer website, this is the only size their produce. Seems that all laser engraver models share same structure changing the features.

pattarom Included with the electronic load, there is a chinese and english manual.
