RV Software / Re: Waffle or static feeder
March 19, 2025, 09:12:26 AM
In RV Setup, create & save a feeder type, passive with the  pitch and #slots required.
Then create & save an instance of that feeder.
Add that feeder to the job, and place it in a centre location
Fill the first slot with the part.
I'm not sure of the "official" way to fill the rest of the slots, which is why I made my "fillfeeder" utility which will copy the first slot to the rest ( need to exit RV Setup to use this)

In the part cdf, select "lock X" and "Lock Y", which stops it adjusting the pick position based on vision results

I've noticed that for some reason you sometimes see duplicate feeders after adding passive types, not sure why this happens, and I don't do it often enough to remember if this causes issues, but it usually works out OK.

RV Hardware / Re: RV4S Driver Belts (and OpenPNP)
December 31, 2024, 12:04:33 PM
If they look OK I'd leave them for now - don't think I've ever seen anyone reporting belt issues.

TBH I'd question whether an OpenPNP port is worth the effort - the inverse kinematics for the RV are very non-trivial, e.g. there are some motion paths that need to be split into two moves due to the limits of the geometry.

Then you have the issue that the downward camera has an angular offset from the head which varies with arm position, and of course part rotation also varies with position.
The original developers needed a machine grid calibration to get enough accuracy.
And even if you get all that sorted the feeders are a bit crap.

An interesting project if you have time to burn, but you easily could end up with something that isn't quite accurate enough to be useful for anything.

I think there may be some partial wiring diagrams here somewhere.
Both boards have serial interfaces- not sure if they share the same serial bus. Don't think I've seen command docs but pretty sure the comms are very simple - a byte or two in each direction.
There is a utility in the standard install called armtest.exe that allows testing of the functions of these boards.

Simple spacer to allow 16mm lanes to be used with 12mm tape

Here's a longer version of the corner for when the PCB is hanging over the left edge of the bed..

For Sale/Wanted, Suppliers / Re: Sanyo Denki drivers

I have a small stock of the hybrids on the Sanyo drivers if anyone needs them - they seem to be pretty reliable though - I had one die a long timne ago, possibly due to shorted wiring.

Storage limits updated - please upload any drivers etc. that might be useful.

RV Hardware / Re: total noob with an RV1s
May 19, 2024, 09:56:28 PM
The only difference between the RV1s and the RV4s is that the RV4s has the flying camera for faster vision of smaller parts, otherwise everything is the same.

On an old machine you will probably need to replace all the feeder belts, while you're at it get new O-rings for the nozzle and tools.
Give the feeders a good clean (but do NOT use oil on the pins as paper dust will turn to sludge).

Put some grease on the Z rack & pinion - everything else should be fine as there are so few moving parts
 
The only documentation is the stuff in the documentation post pinned in the software section. Basic operation isn't that hard - shouldn't take more than a day or two to get it doing something useful.

I'd be interested to see some pics of the QPlacer internals - mostly just curiosity, but might be of interest to anyone else that comes across one, not that there are likely to be many ou there.

I don't know anything about Qplacer but Wouldn't sueprise me if there are similarities to the earlier RV1s/4s so could be worth looking through the documenation for that

Hmm - I just did a teardown of some biotech gear with 20 solenoid valves inside, could come in handy....

I bought a CL feeder a while ago to look at - would be interested to see your mounting details.

I think the only permanent place to edit the feeder indexes is in teh .fdr files, which is a pain - one of the few really dumb design decisions - they should always have been in the CDF as they depend mostly on componant size.

As regards  W98 crashing, adding more RAM might help - ISTR having some issues a while ago that were fixed this way

Received the parts -  was puzzled for a while as they came with no info & took a while to realise what this seemingly random box of bits even was, as it was a while since I ordered!
Having remembered, it then took a while to find any info on assembly as I couldn't remember where I'd found out about it & for some reason it wasn't in my Aliexpress order history.
Haven't got around to doing anything with it since...
