Here’s how it looks in use on a 0402 resistor: The raw view from the Up Camera: 164D9930-97BA-47A0-9D27-8CC65590A1AB.jpeg The view with the Pink masked out of the image, note all that is left is the resistor and the lowest (pickup) part of the nozzle.

(Applies to OpenPNP, and Liteplacer (once Up camera support is available)) I ran into some issues with the Up Camera (new ones) when I needed to run vision with bigger components (like TQFP-64, 0.8mm pitch 1cmx1cm BGA’s, mezzamine connectors, FPC connectors etc.) It required the aperture of the diff...

The sound, sounded like it was coming from the bearings not the stepper motor. Plus it’s around 2000 steps per minute, axis is loaded and it’s micro stepping, so thought it was unlikely it was stepper resonance when I was testing pushing the limits. That said, hearing isn’t great these days so I may...

I’ve noticed the bearings on the X/Y axis start whining way before the steppers start maxing out, which generally indicates the bearings not keeping up which will lead to increased wear. Also it’s a lot of mass to move around at higher speed if something goes wrong (like hitting nozzle holder etc.),...

And for comparison purposes, this is the same machine and settings in OpenPNP but with the Up Camera not used for placement. This is a really good case for why an Up Camera is required in the process, hence why I switched to OpenPNP. B2D56DBC-C48D-42FB-A47B-BD1B13197683.jpeg it’s a combination of er...

Alignment/tuning complete. Amazing how accurate the machine can be (I have the fixed belt attachment points). Here’s a board placed with bottom vision in OpenPNP 0402’s, a SOT23, 0.5mm pitch FPC connector and 0.4mm pitch molex mezzazine. OSHPark board (the weird board reflection is due to post it no...

Out of curiosity, Is it possible to "personalize" the LitePlacer code? Quick question, what language is it written in and what development system is needed? It would seem that the creator is open to contributions, so how would one go about contributing? It is. Written in Java (works on Wi...

I used the instructions and the machine config file here as a starting point: https://wiki.apertus.org/index.php/Liteplacer_PnP_Machine_Notes#OpenPnP_Setup And here's my final machine configuration (including nozzles, 0402 strip feeders and visual homing (black dot on white background)): OpenPNPConf...

So I tried OpenPNP this weekend, and it was a lot less problematic to get working than I was expecting based on previous comments on the forum. Tested a board placing 0402's. I was using OpenPNP latest Stable and a newer standard LitePlacer build + the recent upgrades (new cameras) and Samsung nozzl...

Ignore, figured out what’s happening. I’ll leave it up here in case anybody else runs into it as it’s none obvious behavior. How the Fiducial locating code works (and also homing and tape hole detection and rectangle detection etc), is it measures the location of the object in X/Y, and then if it’s ...
