Tools of the trade / Re: Eagle export script for TM220A pick and place machine
Its a real time-saver for simple assembly work - just do not expect it to be better than 0.5mm precise... We use it for fast proto- and pilot series, and it paid itself well within a year. Most ICs & large components are manually placed, though.
Why did you go for TM-240 and not the new TM-245? (None of them have the missing improvement VISION, unfortunately.)
I have no doing and shall have no credit for the ULP or the Dangerous Prototypes web, but some response for you:
1. The change for TM-240 vs TM220 was just a couple of altered defines. I have not found any better ULPs - and the rotation seems to be the irritating issue; never seems to be able to fix it. A test run and manually editing is necessary every time.
2. ? Cannot answer that one.
3. The Bin 0 is simple enough; just place the component in one consistent corner and calculate the adjusted offset to the center of your component. For each time the pickup head has fetched a component from Bin 0, it will be ready to fetch the next 18mm to the right, then when last of the 10 is done, it starts in the leftmost again. So you may have to refill emptied positions if using more than 10.
So to use it, just access bin0 with correct offsets (18mm feed plus the offset for the component). If I remember correctly, the default pickup is approx in the middle of the compartment.
Good luck!
