Re: Help needed automating a 2 axis David Laser scanner turntable
... this "bi-directional" isn't really hard - look into the serial communicatin samples. e.g. - the "MultiSerial" sample to receive from one port and send to another: /* Multple Serial test Receives from the main serial port, sends to the others. Receives from serial port 1, send...

Re: Help needed automating a 2 axis David Laser scanner turntable
... for bi-/tri-directional handshaking you'll need a software for synchronisation - this can be a simple script on your PC in Java or Processing or ... I've done some of this "handshaking" style applications with different hardware-bases and softwares, so no problem, if you're familiar wi...

Re: Help needed automating a 2 axis David Laser scanner turntable
... you can get one of the 3D-printing controllers, connect the STEP+DIR pins to your stepper drivers and adjust the "steps per mm" so, that it will fit a deg instead of a mm. Then you can "feed" it with plain G-code. For example - homing the motors ist then: "G28 X0 Y0"...

Re: Cleaning metal surfaces with marking laser ...
... this was made with an old IPG YLM-60 type - an 60 Watts CW-fiberlaser with some problem to shut down completely when deactivated (the single spot visible between the jobs). The previous videos were made with a 120W-type with only 3 of the 4 power-banks running, so 85 Watts maximal: https://vimeo...

Re: Laser Projector
Hi Jeff, I have modified several DLP-projectors to "lampless" operation, deactivated the colour-wheel, and replaced the light source with own types (high power UV-LED's or 445nm- or 405nm-laserdiodes with own drivers too) -- so, if you'll need full control, simply modify your projector too...

Cleaning metal surfaces with marking laser ...
Hi All,
... after some marking and engraving, I've tested stripping black paint (development for cleaning metal surfaces):

The result: - on the left a black tile -- on the right the black painted aluminum sheet (Dibond):

Re: David / HP 3D glass calibration panel vs DIY
... you get some errors by position displacement of the marks and some more on not correct set 90deg between the panels. But most errors will accumulate by the optical equipment - optics and objectives of the cam and beamer. David software has some error correction, but this will reduce only some pe...

Re: David / HP 3D glass calibration panel vs DIY
... the quality/accuracy depends on the printing methode and/or service provider, they use to make the panels -- and, of course, on the fabbing (injection-moulding, milling, ...) quality of the brackets.

Re: David / HP 3D glass calibration panel vs DIY
... for me the price for a DIY panel is negligible - maybe 5€ for the panels and 1€ more for the adhesive (or nothing for smaller than 200x200mm) ... but only, because of my tools and resources.
Could be a totally different equation for others ...
