I have a problem again with one of my RV4s. The are a few problems i have so will list them all

1, Sometimes when turning the pc on all 4 LEDs flash on the control card inside the pc as expected bt when loading a job all 4 LEDs flash in turn bt then no movement from the head?

2, Also when powering up the pc i have LEDs on the DSP cards stay on constant, not come on at all, flash at a different rate to the rest of the the LEDs

I can usually get the machine going but can take over an hour sometimes by the time iv powered the whole thing down and back up again (iv currently done atleast 10 power cycles this morning and still nothing) I have replaced DSP cards that i have found to be faulty and this cured the problem mainly but it seems to be getting worse rarther than better, also it can be random as to which DSP card hangs. Things also seem to improve after the machine has been sat doing nothing for a few days.

Any help welcome

I no this is a long shot being as the machines are quiet old nowadays but does anyone know of anybody that services these machines. I have managed to correct most problems but somethings are just beyond me

Thanks for that, i think iv found a supplier and will be gettin some samples in soon. I will also post details of where i got these from for anybody else to use

I assume this is to improve the seal? I actually need new O-rings as the originals have split

Does anybody have any dimensions for the O-rings on the placement head or has anybody had to replace these before and could recommend where to get them from. I have noticed this is very critical to the vacuum seal on also the picking up of the tools.

Thanks in advance as i'm sure somebody will be able to help

I fell even more stupid now because the job was loaded. I can actually get into the calibration menu its just everything bar the tool positions option is blanked out

Thank you, how stupid do I feel not knowing that

Thanks guys, It does like like iv got a corrupt file. Iv tried working all the way back to RV gerber and at get the problem that you mentioned, you open the file and nothing happens apart from the name of the job appearing across the top. Iv noticed this happens when you try and open the transfer file and RV gerber AFTER you have created the job, may just be coincidence tho as i have no explanation for this although  i do have feeders with spaces in the name so what your saying sounds right.
Thanks for the help again

I am trying to access the calibration menu but all options are blanked out apart from the tool position, does anybody know how i can access the other options or am i stuck? I have the username and password and enter them but still i only get the tool position option. Any help much appreciated

On returning to my machine after the bank holiday after trying to open the job film in RV place i received an error message saying "Less the 2 References in Job" Has anybody ever seen this messages before? Also upon trying to find the root of the error i tried to open the same job in RV setup and when opening up the feeder allocation i get an error message saying "Incomplete Job" i only ran the job a few days ago and everything was fine. Has anybody else ever come across this problem? Has the file just become corrupt?

Regards Luke

I have seen a similar problem but what i found was after entering the bias if you pressed the enter key on your key board the bias takes no effect but when actually clicking OK with your mouse pointer the bias did take effect. Hope this helps

I am having trouble with my RV4s machine powering up, when i turn the PC on the 4 lights on the card inside should flash together, right? The problem im having is the LED on the card closest to the back of the PC hangs and then flashes in a different sequence. Any ideas what this could mean?

Also after letting the PC boot up i wait power the RV4s bt nothing happens and i just get a series of "Write readnotbusy error" messages untill im told to correct the fault and restart the machine at witch point the arm will sometimes jerk backwards. Power cycling the PC and machine sometimes corrects the fault but as you can imagine this is a bit of a pain and does not always work. Any ideas to my problem would be much appreciated
