OpenPnP: Multi-Shot Bottom Vision

Align parts that are too large for the camera view, or not rectangular, and more.

OpenPnP: Automatic Machine Calibration with Issues & Solutions

Created a Pull Request for Automatic Machine Calibration with Issues & Solutions. Watch the video Read about the new Vision and Calibration Milestones on the Issues & Solutions Wiki page. Read about the new DirectionalSneakUp method on the Backlash Compensation Wiki page. Join the discussion. Download the OpenPnP 2.0 testing …

OpenPnP: Nozzle Tip Changer Vision & Z Calibration, Part Height Sensing

Made a new OpenPnP Pull Request that adds Nozzle tip changer XY and Z calibration using vision and probing. Used to calibrate the nozzles and nozzle tips to be able to precisely contact probe part heights, feeder heights and placements. Also adds Auto-Focus based part height sensing for parts with …

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. …

OpenPnP: Global Axes and Enhanced Motion Control

UPDATE: These features (and much more) are now part of OpenPnP 2.0. Read OpenPnP: Advanced Motion Control. The first step for more advanced Motion Control in OpenPnP has been implemented and a Pull request posted. This is the foundation work. The fancier parts of what was discussed in the group …

OpenPnP: Advanced Camera Settling

Made a new Pull Request to OpenPnP. When the Camera needs to take a picture for Computer Vision, it needs to be stable, i.e. all machine motion, vibrations etc. must have ceased. For the machine to be fast, this should be adaptive tho the motion that the camera observes. The …

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 …
