Yes, going fast and adding a blower to the laser head, made the edge more clear and the kerf of the cut extremely small.
I mesured it with a micrometer and the difference between the perimeter of a small square of 10mmx10mm and the small square cut out is just 100 micron...very impressive
Tank you! that explain evrything.
i had thinked tath the software might use the same feed rate i set for the cut but i asked to be more secure of this.
Adding a trace frame feed rate parameter in the laser control interface can be a nice and useful idea
I've got the blower fan mounted on the air assist mounting from Thingiverse (https://www.thingiverse.com/thing:2545095 - which I need to modify slightly) and the fan is connected to the top of the laser module. It is quite effective and there isn't any smoke damage on card or wood like before.
If you want to connect the blower fan to the laser module as I mentioned in a previous post, make sure you take some ESD precautions when handling the module. The four screws are self tapping and go through the laser mounted fan to the metal heatsink. You don't want to undo these screws more than once, otherwise the threads in the heatsink will foul.
The cable to the blower fan can be desoldered at the terminals on the fan body, cut down and resoldered, to shorten it.
