Hi,
Very insteresting design... Am I mistaken or the "out of center" leadscrew is because you are "restraining" horizontally on just one side ?? That way it will never bind, right ?
Is...
It surely does... I like the way you have all pieces as short as possible. That should help a lot with the stability of the machine..
When do you plan to have it running ? Please keep us...
Hi, Marc
The machine looks great... Could you post more pictures of the details ?
Best regards,

Sorry to disturb, but experience is better asked than acquired the hard way :bat:
The bottom rails you drilled both sides at once ? Was that enough for aligning the rails ??!! I see so many...
Hi, Joe
How did you align the rails ?? I saw that you took off the alignment blocks ! Your design looks great and simple.. Please tell us more..
How did you align the whole thing ?...
Hi, Paolo
Let's keep the feeders for a second phase... They are complicated....
Precision is not a big problem with 0805 components and SOT-23 ! They self align nicely of you put enough...
No hate... Nice advice is always good to hear...
I am making about 25 boards mostly every day with 2 people working on them using hand held vacuum pickup needles and with components in small...
Hi, Marris
Nice to see you in this thread.. Lots of real World experience with the pick and places machines combined with the best drivers for the price that I have ever heard off :cheers:

Hi, Paolo
The pressure sensor is how it is done in comercial machines.. I think it is a great idea but.....
Nowadays I really became a believer in " Evolutive " development :)
Lets...
Hi,
You just apply the solder paste before putting the parts on the board. The solder paste surface tension is enough to hold the components in place. No need for glue for small parts.
You...
Hi, Paolo
Using rack and pinion for the Z is not a good idea in my humble opinion. We do not need speed there, it will just move some milimeters to clear the right of the SMD components !! And we...
Yes, one stepper for up and down and another one for rotation. The neddle actually rotates 270 degrees. I have not got to the point of actually picking up the components :-( My idea is to have some...
I cut the needle with a sharp "xacto" blade rollingundefined it back and forth slowly to get it as flat as possible and if necessary I use very fine grit sandpaper to finish it up. www.smallparts.com...
I am planning on just using the table for small components... Not for the big ones that need the suction cups. I use a aquarium pump modified to make vaccum for the manual pick and place I use today...
Ok.. Let's forget the software by now... It is not trivial but more than easy enough to solve when the machine is operational..
The Z, rotation and vacuum pick and place is also quite easy. What...
If you want you can send me the emails and I will ask the guys politely in Portuguese and see if we can clear things up... It may even be just a misunderstanding with people trying to ask you...
They will go into a reflow oven. Component type and orientation is also part of most BOM generated by PCB's programs. And for small productions that could even be entered by hand without much...
The "bindomatic" new word is something I read at one of John "cranky" ********** message somehwere.. It really defines my first go on the machine very well...
I used Igus bearings and the guy...
I am interested.. I already started something but the results are really not very good.. I made a "bindomatic"... The space between the bearings blocks is too big and it just binds all the time. I...
Hi, Alan
I am down in Brazil... If you need any help I can see if I can find who is selling your design.. And at least we can try to stop it..
Do you have more details that you want me to...
I comptetely agree.. A gantry router that is easy to build with common tools....
Nice looking machine. Congratulations.
I was not able to make out from the pictures at your site how you guided the Z axis ! Could you explain or get another picture of that axis and how it is...
