* Vacuum sensing is now supported: https://github.com/openpnp/openpnp/wiki/GcodeDriver:-Command-Reference#vacuum_request_command What kind of hardware is required for this? On the liteplacer and openpnp front after months of building, fiddling, learning and testing I finally arrived at a state that...

So I have read around a bit how to properly tension the belts on the liteplacer. So far the information I found is inconclusive. I was hoping people here can help narrow down the answer. -) If the motor makes noises while spinning the belts are too tight -) if the belt makes a low audible note when ...

Please grab a multimeter and measure the resistance in each cable pair?
Also check if the cable pairs have no connectivity to each other with the multimeter.

I created a machine.xml that makes OpenPnP work with my liteplacer out of the box (no need to run liteplacer software first to program tinyg or send custom gcode to the tinyg): https://wiki.apertus.org/images/d/de/Machine.zip It configures tinyg at connection/startup and also activates pump and val...

Also, Jason said, that " TinyG users can use the GcodeDriver as far as I know". https://groups.google.com/forum/#!topic/openpnp/j-TAyyZ9XQ0 , last few messages. I created a machine.xml that makes OpenPnP work with my liteplacer out of the box (no need to run liteplacer software first to p...

I am happy to share pictures and design files of our build. We bought a cheap MiniITX pc enclosure and created a custom plate to attach tinyg to where the mainboard normally resides. The DC power supply is not properly attached yet but we are currently too lazy to drill holes into the bottom of the ...

I found a workaround solution to trick the bottom vision camera into dimming brightness: attaching a white paper label to the table to partly fill the cameras view with bright white elements Details (also with bottom vision CV parameters for nozzle tip recognition): https://wiki.apertus.org/index.ph...

> I am evaluating whether this issue is caused by the tape being slightly off angle from the vertical machine axis. Could be, but doesn't seem to be so. The images don't show any off-angle, and the error is rather big. Do you have slack compensation on or off? Do you see the same if you go first to...

I shared my own findings here: https://wiki.apertus.org/index.php/Lite ... hine_Notes

In summary the nozzle offset with the samsung nozzles is neglectible though

I am using a white paper tape with 8mm width and 2mm pitch. 0402 components. The weird issue I notice is that just going 3.5mm left from the hole center (as liteplacer does by default to pick up components) gets us into the component of even part numbers center location pretty well. But going 3.5mm ...
