This is included already, you can also enter the number of parts in the reel.
I had a look in the function, you need to positon the downcam corsshairs to the part in your feeder, then select on the tape "Set as Feeder"

Works perfect, just placed a board with a feeder, positions exact on the part in the feeder, my try was in a parthole of a tape, and it always returned to the same hole, so it workes.

Sad enough, I do not have feeders

Nice, thanks for taking the time to check that out, much appreciated

Hmmmm, yes auto feeders.... They would be really nice.

Was anyone able to place bottom layer? the software does not make any difference, and even if I put the width as a negative value on offset X the software would the machine wants to move outside of the limits. any recommendation?

[Pixopax]

I just work on a ulp-script for Eagle which extracts the bottom parts data
It mirrors the parts position so you can put it on the machine without any offsets.
Its ready tomorrow. I also made a 90° rotation as I often design in landscape mode but place in portrait mode.

But if you do not use eagle...

I just found the solution: I should activate "Populating Bottom Layer" BEFORE loading the pick and place file . and I guess I should also have one file for top and an other one for bottom

Hi Pixopax,

thank you for improving the software. Will you publish the sources/binaries of your version anytime soon?

[Pixopax]

I would, but Github does not want it
I tried today to get the knaster-fork again, started all over, got the right version as it seems, but still I am nozt visible in Github, also, I cannot commit changes to that fork.
I did not have much time to try out more, as I had to place some parts today, my first real boards came out of the machine, finally

I tested my eagle script to make the parts list, placed to and bottom and everything worked.
I only still have some problems with parts jumping out of the tape, that is annoying, but not so tragic.
Also, the rmod-fork seems only to know 8mm tapes, 12mm or more is not possible.
So I placed the bigger parts by hand.

Good job, the placement looks really accurate! I'm still trying to get a better accuracy with my machine. Were you able to place the QFN chip automatically?

I'm using git at work but I can't help you with github since I've never used it. It might be easier to maintain your own fork without pushing your changes back to original
repo.

The software crashes in the moment I try to take a picture from the component, so that does not work with QFNs.
I only placed 8mm tapes, something else is not possible in this version.

I also came into trouble in a strip to the far left of the table, the software refused to add the tape, it went doen 2 holes then crashed.
I placed the tape further to the right, then it was ok, no Idea what that was.

Also, I had trouble with the Z-Axis, the needle calibration did not work correct, as the air tube in the hollow axis started to modify the position of the needle, I could see that in the cam, everytime the air tube rotated back the needle made a jump.

My todo-List is: Add other tape formats as 8mm, renew the Z-Axis with the parts Malte showed us, add a pressure sensor, as I had some parts not picked up.

Hi Louis,

nice boards - I like the combination of milling and V-scoring on your panel.

Do you have Misumi account to buy the parts for the Z-enhancements? If not, ping me and I might be able to help.

Regarding git, let me know if you want support. I'd be happy to help, as I see a benefit for all of us in enabling you to share your work
