OpenPnP: Camera light actuators and more

There is a new testing version available featuring new built-in camera light actuation (no more scripting). It can support new Profile actuators, so you can control multi-channel lights like RGB etc. A pipeline can optionally control the light actuation, so different light profiles can be used on different pipelines. In …

TinyG: New G-code commands for OpenPnP use

TinyG is often used for Pick & Place because it comes with the Liteplacer kit. Some features have been added to TinyG to make it more like other controllers and to optimize its use with OpenPnP. UPDATED: see dates in the sections. New commands for OpenPnP This Pull Request implements …

OpenPnP: Advanced Motion Control

Made a new Pull Request for OpenPnP Advanced Motion Control and documented migration and usage in the Wiki.

Camera FPS, CPU load and Lighting/Exposure

I’ve just confirmed an old suspicion of mine. Camera frames per second (fps) depend on lighting or rather on the exposure you need to set for the given lighting situation. This is at least true for the ELP FullHD camera and the new 720p 120fps global shutter camera I’m evaluating. …

Smoothieware: New Firmware for PnP

The Open Source motion controller firmware Smoothieware is optimized for 3D-printing, milling, laser cutting and similar. It is a very nice and versatile firmware but sometimes problems get exposed in the Pick&Place use case. I found and fixed some missing features and bugs and tried to contribute them back to …

Choosing a Motion Controller: The Panucatt Azteeg X5 GT 32bit

Most motion controllers today use a universal language called G-Code, a de-facto standard that incredibly dates back to 1950. G-code mainly just moves mechanical axes around in a completely abstracted manner, so you should be able to do anything with it, right? Does it even matter, which controller to choose? …

OpenPnP: Advanced Vacuum Sensing Part-On/Part-Off Detect

Made a new Pull Request to OpenPnP. Vacuum sensing part-on/part-off detection was significantly expanded to allow for differential vacuum level assessment and adaptive dwell times. Adds graphical diagnostics. Easier setup with Measurement Method combo box. Detection can be switched off without having to overwrite your values. The method combo box …
