*sold* Fully assembled Liteplacer for Sale (Central Europe)

I put the liteplacer on a very solid 4cm thick black kitchen MDF plate. There are 4 table legs attached that can be take off for shipping. The Tiny...

Re: Openpnp

Yeah, we're using your fiducial PNG, now. One issue is that it didn't seem that your published machine.xml had any fiducial-home stuff in it.

Re: Openpnp

UPDATE : We did get the homing fiducial to work. It turns out that it can ONLY be a white (light) dot inside of a black (dark) area. I assume all fiducials are like that until the (potential) new update comes out with a fiducial pipeline. Correct, see: https://wiki.apertus.org/index.php/Liteplacer_...

Cable chains issue / first element gives way

Once the cable chains have been filled with all the cables going to the head the weight can lead to the first element of the chain giving way. We created a small 3d printable piece to put between the cable chain and the sheet metal to act as support structure for this first cable link element. To ma...

Re: Openpnp

I now got optical homing and the nozzle tip changer working with OpenPnP. Really interesting !! I would really like to get some more easy digestible information regarding OpenPnP on LitePlacer.. Did you or someone else collect the information somewhere - maybe even in a "step-by-step" gui...

Re: Openpnp

In my opinion the current approach to detect failed pick ups with the bottom vision camera is the way to go - all the hardware and software (not 100% in openpnp yet but its wip) to do that is already in place.
