Hello All, I have been working on an open source feeder design for my LitePLacer machine in my spare time for several years and now think I have it cracked. I'm currently writing up the design to put as open source on instructables. PnPFeeder.jpg The feeders include: 8mm / 12mm / 16mm tape width sup...

To be honest: As a software developer I must say: This Software is a real piece of crap. Sorry for the hard words, but it is chaotic, unstable and has so much errors, that I stopped counting them. Every error leads to a hard crash, which is insane. I cannot understand how someone here is able to pl...

Hi Adam,

Sounds great I'm into my Java thanks to Android and run a separate embedded forum so I know what you mean about having time and giving support I'll keep an eye out.

I'll get the 3D file shared onto Thingiverse when I get a minute. For now anyone without a 3D printer can get hold of them via my eBay 8mm & 12mm https://www.ebay.co.uk/itm/283209214795 16mm & 24mm https://www.ebay.co.uk/itm/283464958568 24mm, 32mm & 44mm https://www.ebay.co.uk/itm/28362...

The biggest challenge is to avoid "jumping" components when the needle takes adjacent ones.

Yep in the tests so far I have been able to pick up and place back down without disturbing neighboring components. Though I have not done a full run yet. Waiting on PCBs to arrive.

First tests seems ok I can move from component 1 to component 35 on each strip without any issues. Component 35 is about the length of the holder.
If you want one of these holders then please let me know.

Hello, Yes it's still doing it on the latest version and it is also occasionally doing it when the needle calibration goes through ok. Timout.jpg Here is the log from the end of the needle calibration and where the error appears. The error appears around the sr:{344}} mark. The {"sr":{&quo...

Hello, when I tried, I got correct "sr" responses when I moved only one axis My machine is working well but I do get this error when the needle calibration fails (due to up camera not firing the first time, the needle machine vision algorithm not being quite right or the needle not having ...

then you dont get issues of PWM and frame rates causing weirdness for the vision system

Good call I hadn't thought about that. Though I can probably clock out PWM at a few hundred KHz which should hopefully work with the cam? I'll have a play might need a simple RC low pass filter on the PWM.
