Jason, I tried to change the polarity. In this case, the Z axis moves in the right direction and coordinates increase when moving up, and decreases when moving down, as it should be. But I still was not able to configure the sensors to the machine properly search home, because sensors are connected...

It should be possible to invert the Z axis just by changing the configuration in TinyG.

If this work, we can just send this command from OpenPnP during connect to make sure it's always set right.

Thank you JuKu! I'm Jason von Nieda, from OpenPnP. I've been monitoring Pixopax's OpenPnP thread and helping where I can. In the near future I will be working to make sure that OpenPnP works well with the LitePlacer hardware and will, once we have the problems sorted out, be posting a Wiki page with...

Yes, I had an issue with the homing of Z, Jason made some suggestions on how to overcome that problem, but that did not work. It drives the Z-Axis down when it searches the Limit-Switch. It should drive it up. Jason suggested to rewire the Limit-Switch, but that would not change the wrong direction...

I've been having very good luck with this by using the HSV color space. Actually I don't think HSV had anything to do with it... you covered up the curves with a flat disc to hide the curves! :) I'd like to see the before/after shots of your HSV manipulations without the green disc in place. I trie...

I've been having very good luck with this by using the HSV color space. I subtract pretty much everything between yellow and blue which gets the vast majority of the nozzle and then the threshold gets everything that was too dark to discern a color from. You can see an example here https://www.youtu...

Just had an idea for the Juki heads, based on the discussion in another thread with the inductance to digital ics.. would it be possible to touch the two ends of the spring at the end of the nozzle to measure the inductance change as it compresses? My main worry with something like this is that get...

Hi WayOutWest, Really nice work, and I love the use of MSER. It seems like a great solution to this problem. As others have asked, would you be willing to post source code or a description of your work? I note that you mentioned FireSight, so even if it's just your FireSight pipelines that would be ...

I think the latest release fixed this. (<rant> Once more, one of those "works for me, not for customers" -cases. I really should have an XP, a Vista and a w7 machine - but don't have room for these, so unlikely to happen. </rant> ) JuKu, I invested in a copy of VMWare and copies of the al...

I highly recommend taking 15 minutes and going through this tutorial: https://try.github.io/levels/1/challenges/1 This will help you understand the distributed nature of Git. Once you understand this, branching, pulling, pushing, forking and pull requests make a whole lot more sense. The core concep...
