Hi I am new to the versatronics RV4's
I am trying to put down Ic's that are on tape. The distance between components seem to need 4 Indexes. I have set this up, when setting up the feeder.
However when you step the feeder, it only indexes once. Any help much appreciated. ???
When you say 'step the feeder' do you mean during a placement run, or when setting up the feeder?
Also let me know the size of the file 'place.dll' that can be found in the folder c:\versatronics\rv\
Manual index operations always advance one step.
Multiple index lanes must be defined in the feeder definition - although it looks like you can change them in Edit Feeders, this has no effect.
When using a multi-index lane, it picks, and indexes once. If vision passes, it indexes the remaining number of times.
This is done so that it will retry one index at a time until it's in-step with the part spacing. However you need to set the number of retries to at least the number of indexes per part.
Here's an example of a triple index working

Seems to only index once when it is manual or during placement. the Size of the "place.dll" is 268KB.
Also having trouble picking from Vib Feeder, Have set up references and set component location, Hight etc, but doesn't want to pick. Any help would be much appreciated. seem to be going round in Circles, double checking.
But cannot see what I'm doing wrong.
Also what should the Results be when you run ARM TEST?
I believe Phono found some differences in behaviour between various versions of place.dll hence the question. As Mike mentions you do need to edit the definition of the feeder itself in RVSetup, and change the index count here for the lane in question. You would then want to save this with its own special name as you will undoubtedly need other indexes for other jobs. Now when you setup the job you make sure you choose that new feeder and put that part in the relevant lane. In Rvplace there is a box that allows you to override the default setting, as they state it doesn't really work. On our machine it did work as a temporary change but was not stored and could also be randomly reset itself of its own accord.

ARM test, shows you some readouts from the various sensors, as you can see. You can twiddle a couple of those and observe the readout changing (the ones on the head being the easiest to get to). They should mostly be kinda central IIRC. I have vague recollections of one of the buttons not quite doing what you might expect... If there were problems visible here I suspect you would already have seen evidence of it when placing.
I don't recall any problems like that with the vibratory feeder, perhaps you could describe exactly what it does when it should be using it?
Hi Gopher, Pickup goes to position over Ic, But doesn't pick up Goes into Edit CDF, But no Component picked.
As for 24mm feeder I am at present again addressing the make feeder section and trying to alter that. I'll see what happens.
Fear I can't see the wood for the Trees.
I'll have to just keep trying things. Although I think I have addressed all possible items with no success.
Sounds like the component definition for the part in that lane has the box checked verifying your definition using the camera. Perhaps that definition also currently holds some spurious settings as to the pick parameters that is stopping the pick happening, I would read though them all and have a look for anything weird.

Never seen that - try using a different part in case there is something odd in its CDF
Have you set the feeder refs and heights?
Is the feeder lane location at an extreme position that might be just out of reach of the arm?
I think most people find setting up their first couple of jobs very frustrating, but once you get familiar with the quirks it gets much easier.
Hi guys. Been watching this thread unfold but been stupidly busy!
Ok. The vib feeder problem, from what you described, sounds like you are testing a CDF (Run-time test), but haven't set the feeder up properly so its not picking up the part. The only way out of that it to cancel and test the CDF again once feeder height/position is set up. Set the lane position and height from within RVplace.exe, then re-tick 'Run-time test' for the package you are trying to pick.
Now then, this multi-indexing. To get it to work there are a few things you need to get right. First and foremost, you need the other 'place.dll' thats 1.7MB. Bin the one you have - although its newer its got a lot of issues, and the only issue I've found with the older (and larger) version is that if you use 'auto fid correct' you may find that for the very first part in a run, the head retracts late, so the feeder has started to advance already, resulting in a mis-pick for that first part. But multi-indexing works.
I'll attach the place.dll file you need to be using.
Give that a go and you may find things work a lot better. You still need to bear in mind the quirks of setting the number of indexes. Personally I always set the indexes within RVplace.exe, using the edit feeders button from the placement screen. Down side to this is that you need to re-set them each time you open the program, and editing a CDF or setting up feeders randomly loses them too. The alternative is to *I think* define number of indexes when you define the feeder, but I've found this to be a bit unreliable too as I recall.
I've seen another related post in RV software area so will reply to this separately.
Hi Phonoplug,
I am picking the Ic from the vib feeder, checking in the test CDF, it usually seems to place first component, then drops say other 5 in the bin.
I have set References on feeder, also centre of component to pick and height settings. As far as I'm aware this should be all I need to set? Thanks for the Place.dll file, I'll download tomorrow when I get back in work. Thanks for your help so far, also any further help you may offer. much appreciated. Aub
