Yes, remove feeders, unplug the connectors from the bottom rear, and the arm/table unit just lifts off.

Might help if you could post pics of what you are seeing.
Also, if you set the cam threshold way off, so it sees no features,
 think it shows the greyscale video image-this may be helpful in identifying issues. Could be a wierd issue with the capture card, or maybe a video ground off, so noise from somewhere is causing interference.
A regular issue is the IDC 0.1" headers used in various places-may be worth replacing the ones on the arm board with crimped or soldered ones like JST or Molex. Maybe also put a scope on the camera power to see if there's any noise or glitches.
I thing the video signal passes through a relay on the arm board to switch between otf and fixed cams. If monitoring the video, ty to do it at the input of the capture card

Regulator is on the PCB on the side of the arm.

If it's stray pixels etc. Try tweaking the camera threshold. Also check for marks, paste etc. On the lower face of the nozzle

I've seen an issue that looks like it's getting the fields of the interlaced video frame the wrong way round or similar-a comb-like appearance on edges. I think it can happen if the video signal disappears, e.g. bad video or camera power connection.  Once it starts, it happens consistently until power on everything is cycled
I think I saw it when I powered up the RV box before the PC. Haven't seen it since I made a habit of allowing the pc to boot before turning the machine power on

AIUI the X/Y aspects of these functions are basically equivalent. Setup just sets the initial values so the fid cam starts in roughly the right place

Saved searches on ebay are handy when looking for very specific things like this. I got my spare capture card at a good price after a few months

Centring of the feeder pick location isn't a huge deal as unless feeders are locked in the CDF, it will tweak the pick position over multiple picks until it's centred.  This can be an issue if the vision isn't set up optimally, such that the centre position isn't very consistent. Inductors with solder on the bottom are a regular problem.
Locking feeders can be helpful in some cases, but the first thing to do is optimise the vision thresholds and blob size.

I've seen this a few times, I think it was a stuck button on the gamepad, or the gamepad getting into an odd state that was fixed by unplugging & replugging it.

For Sale/Wanted, Suppliers / FS RV1S - £100 Loughton Essex.
« on: October 21, 2019, 11:14:04 AM »
Part of a lot I picked up a while ago - RV1S base unit only with PSU box and PC. No frame,feeders,nozzles or PCB holders. I did have it running a while ago but it's just been sitting gathering dust since.
I have an RV4s so not likely to be very useful for parts & now want to clear the space, and I can't be arsed to set it up again to demo to a potential buyer, so prefer to go to someone already familiar with the machines as a spare. 
Collection only Loughton Essex

I'll take 10 - let me know how you want payment

By "screen corruption" do you mean the well-known thing where the screen display becomes offset, or something else?

Incidentally the quickest way to recover the former is to load any other job, ignore the feeder error messages, then reload the job you were doing. This avoids the re-homing delay when starting RVPlace
