Here are the basics for theta issues in teaching: 1. CAD part library should match machine part library orientation. 2. If your placement orientation is correct and your feeding orientation(orientation in your feeder) is correct, there should be no

Hi everyone, this is my first time on this forum. I've only been an innocent bystander. Until now. I wonder if anyone out there knows of any technical publication (accessible over the net) that explains, in detail, the actual physics involved regardi

Yea, I always liked to program the way it physically sits in the feeder then rotate as needed in placement. Make sure rotation in feeder is 0 as well or you'll really get confused. Some machine mfg's recommend otherwise but it never made sense to m

In trying to have things run smoothly with placement, I have to do a lot of theta adjustment to get the rotation right during placement. Even if the part looks good on the PnP machine screen sometimes it places differently than what is shown. If I u

Any advice how to (easily) replace theta timing belt on GSM Flex head?

For the past few weeks we have experienced an intermitent midas theta error.During normal production the machine times out while just after picking up a component waiting for the theta to center it.Sometimes it fails to leave a tool. Reinitianing the

According to the message guide it just says that it's a error telling you to initiate the Hydra Theta axis. I suppose the encoder for the hydra theta motor could be losing count and causing it to need to be re-initiated, or it could be something to

... and don't forget proper stencil alignment. Invariably I find most bridging problems for fine pitch parts, etc. is caused by lousy alignment. The alignment must be verified under magnification, using the naked eye is not good enough. Use at least

My Quad IVc's will also do the same thing. Mine are equipped with CyberOptics scanners, not QuadAlign. The Cyberoptics scanners do go bad and once they do, they get very warm to the touch and at the same time, if the Quad is reset, the theta axis wil

Thanks for the answer, RLM, I couldn't find anything in the manual that was helpful. If I use a common extent for each component type, I need to identify those components that may be turned due to the feed type (tape, vibe). Is this where I would d
