Similar projects worth following. Within a few years, he co-founded the Weston Electrical Instrument Corporation. Hi Marinus, we can discuss this here too — quoting the last post from LPF: While magnetic motors operate through the attraction and repulsion of magnetic fields, electrostatic motors exploit the attraction and repulsion of electric change to produce motion. Piezo stacks are ideal here though hackers have also used cheap buzzers! Sometimes though you need high precision over a larger range of travel.

Arduino Firmware to Control Galvanometer Drivers

One of the cooler applications however is the mirror galvanometer. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies. For some applications however resolution is of primary interest rather than range of travel.

Writing arduinp to create a raster scan to make a rudimentary TV style screen Making an oscilloscope or ECG Using stepper motors rather than servos. One such application is MEMS motors, tiny often less than 0. However much like piezos it can also be used for high precision motion. These often require sub-nanometer accuracy less than th of th of 1 millimeter in order to visualize individual atoms.

Laser Galvo: Arduino Controlled

Sometimes though you need high precision over a arduion range of travel. As it turns out, he used that approach in an earlier projectbut this time around, the hard drive only donated its platters for use as low mass, first surface mirrors. Even the audio is faithful to the original. About Us Contact Hackaday.

Laser + Galvanometer Control

I don’t think any of them are particularly laser-cutter specific though. In any case, their mechanisms are interesting in their own right!

Check it out in action below. There are a number of piezo configurations that allow this.

You can see it in action here https: What education film about electromagnetism would be complete without an iron filings demonstration? It is here that piezo actuators really shine.

Magnetostriction is the tendency of a material to change shape under a magnetic field.

Meters are largely digital nowadays, but their analog ancestors are still widely available. The screw can therefore be made to rotate. But instead of it being a laser show I want to engrave metal.

When we’d drive galvo motors from the DAC-audio-ports of the Duet, would we need a stereo amplifier? Click here to login.

Arduino Firmware to Control Galvanometer Drivers

Piezo stacks are ideal here though hackers have also used cheap buzzers! A current through a coil moved a rod to which a mirror was attached. These systems are effectively high speed vector graphic like line drawing systems, resulting in a number of interesting algorithmic challenges. Similar projects worth following. Magnetostrictive actuators Magnetostriction is the tendency of a material to change shape under a magnetic field. And the LEGS and similar Inchworm actuator allows relatively quick, high force, and high resolution motion.

I understand that standard servo-type galvo drivers use V differential inputs. By inverting the process extending quickly, then compressing gxlvo the process is reversed and the screw is turned in the opposite direction. Arduin for DIY use, it sounds gakvo a resolution of 1 part in would be adequate.

In particularly the finishing of precise mirrors and lens used in semiconductor and astronomical applications.
