Laser cutter/engraver
The frame we are going to be building is based on carriages that use V-wheels. These are commonly available online from a variety of sources. Let’s begin with a brief discussion of the general design. Like the plotter, the laser cutter uses a cantilever arm for the Y axis on which the toolhead moves. The entire arm moves in the X axis and the toolhead can be any desired laser head you desire. You can use exactly the same type of board you have on your 3018 as the motherboard for this machine and you can flash GRBL on it, just like the 3018. In addition, you can also attach an LCD controller to operate it offline (i.e., without a computer). You can also attach some other commonly available boards such as the MKS DLC 2.0, for which you can acquire a TFT controller flashed with firmware specific to laser cutter operations.
Here’s a bill of materials for the laser cutter frame:
