The z axis was making a grinding noise so I decided to replace the rack and pinion, in the end I changed the pinion and turned the rack back to front as only one side was worn, on reassembly I went through the calibration procedure for the cams using tool 2 and tool5, and reset the focussing etc for camera 1 and camera 2, I then ran the tool height routine which seems to run without a nozzle fitted (no instructions).

Since carrying out the above I have a problem where the machine cannot put the nozzle back into the tool station, and occasionally doesnt pick up the tool, I have never used the tool station height calibration before and I am wondering whether it needs tweaking somehow so that the nozzle is picked and place lower in the tool station to allow it to turn and lock properly.

Any Ideas?

Hi I Have spotted an RV4S on Craigslist, if anyone is looking at it then be careful as the Pics shown are of a machine I bought on Ebay in November 2014.

Very confused newbie, I have finally got to a position where I can place parts but having placed a pcb where errors occurred I manually placed the parts missing and went to go on to another board, my problem is that the machine still thinks there are 2 parts left to place which it will happily place on top of the existing parts but after that they are still listed as being unplaced, I have tried using the reset components button but is doesn't change anything, there are no errors listed and no matter what I do the machine seems to be stuck like this, any ideas!.

regards

As some of you may have seen I have had to remake a few of the Nozzles as the original parts on the machines were unusable, this has got me thinking as the replacement parts have been stainless steel why not remake the whole nozzle that way. I can see a problem with using metal nozzles is that they might get bent If knocked or worse still damage a feeder or the arm, so my current thought is that if the tip were held in by a reasonably strong magnet it could then detach if a problem occurs saving both the nozzle and the machine. Any thoughts?

Hi I have a 20 way vibratory stick feeder which is built as a two tier design, I haven't seen another one listed anywhere it seems to work ok in itself but I am having problems getting the arm to reach the top tier as it is further back and the machine keeps telling me I am at its limits, this feeder came with my machine and is made by versatronics I just wonder if it was for a different machine.

Any help would be appreciated.

Hi I am wondering where everyone is getting replacement nozzles from as both my machines have broken and worn down nozzles, also how long would you expect them to last.

Hi this is my first post in the forum although I have read most of the other posts on here and learning a lot from you guys.
I have 2 machines an RV1s and an RV4s both of which I bought separately on EBay last year.
I am setting up for a small first production run on the RV4s and have come across the grip issue on plastic tapes, after a lot of trial and error I have finally diagnosed the cause of the problem. I found that if you used a double thick section of plastic leader tape that the friction issue disappeared, this meant that it wasn't a material problem, I also noticed that the tape would only feed forward not reverse when single thickness and that however hard you pushed down on the roller the friction on the tape didn't increase. it turns out that the roller is actually in contact with the plate that covers the indexing pin but only when the roller is too low on thin materials, so this is a design/ manufacturing problem with the machine.
My solution for my own feeders is to hollow grind the front end of the metal strip, I found some feeders don't have the problem because of manufacturing tolerances they just miss each other, I am sure there a re a few ways to remedy this depending on available resources.

its easy to test if this is your problem pull a strip though and where you find it wont grip remove the two screws holding the plate in place and nudge it back out of the way and try again, mine are working faultlessly now, I hope this helps someone else.
one other thing, you can actually see the wear on the plate caused by the belt rubbing against it.
