Blade holder mechanism bouncing – help please?

Posted by Warren Beard on July 29, 2015 at 1:59 pm

Hi

Our Roland XR640 has just started giving us problems with cutting, the blade holder should stay sprung up against the top of the carriage (like on a stiff spring holding it up) however it keeps dropping down and "bouncing" as though on a soft spring and sitting half way down and seems to bounce when going through the cutting motions.

Sometimes it’s fine and then half way through cutting or at any random time it goes loose and cuts erratically.

Anybody have any ideas and also if anybody can recommend an engineer in the Hampshire area that would be great.

Thanks

hope you are well mate, sounds like you may have a break in a cable, i know your machine isn’t mega old but there seems no rhyme or reason as to when these go it depends how they lay back down as the carriage moves. You could check connection plus haven’t worked loose

Many years ago we had a similar problem with a Roland cutter, it turned out to be a solenoid in the blade holding unit

Well taking a closer look I don’t know what the black dust is from from something’s rubbing and wearing something down. I think it may be this dirt on the strip causing issues?

What can I clean it with? is IPA OK to use on it?

Thanks Warren

IPA should be OK, but don’t use anything any more aggressive like head cleaning solution.

As Kev says though, I would probably look at the cut cable and guide. They’re pretty inexpensive to buy.

Update: it was a cracked cable which has now been replaced and working good as new again. Surprised it didn’t last that long, cheap part but 4 hours to replace by an engineer isn’t cheap that’s for sure 😉

Thanks for your replies, much appreciated.

4 hours!!??

Seems a bit excessive to replace the cable and guide, but maybe there was some other service work done at the same time. Did you get Roland to do it?

Printmax, I suppose maybe about 3hrs as we did spend some time asking other questions etc and he checked one or 2 setting.

Fair enough. As long as it’s up and running again, that’s the main thing.
