Cutting Dibond with excalibur 5000
Hi all, first time on here, came across it on a search.
Ive just bought a Excalibur 5000 to cut dibond on my new UV flat bed.
Have cut foamex, correx etc.. not a problem. But have come to cut a full sheet of dibond & i cant get a straight line. The top 6" are fine but then as the off cut runs up the chanel the line goes off up to 20mm when i get to the bottom of the sheet??Anyone else suffered this problem/know any tips to get round it?
or am i being stupid & not doing it right?? have read the manual, searched the internet etc… nothing as far as instructions or tips on cutting different substrates.Regards
James

ive managed to speak to someone, who is sending me out a new cutting wheel assembly. not sure if this is going to do anything?
-
I wouldn’t have thought that a new cutting wheel assembly would do any good.
The cutter comes down it’s rail, so it can’t move off course. That means that the dibond must be moving as you try to cut it.
My first action would be to look at the clamping pressure.
-
ive tried it with one person holding the clamp firmly down & one sliding the cutter down. it makes it stiffer to cut but still cuts at an angle? madness.

I bought an Excalibur 3000 from sign UK and have noticed the same problem, I would be very interested to hear the result/outcome. I haven’t contacted our supplier yet as I haven’t had chance to check all the alignments properly. I think I must go and do that now…
-
I also have had the same problem, and the only way around it as far as I have found is th only cut large-ish pieces. Trying to cut anything less than 2-3 inches causes a wonky cut! 🙁
This of course is useless, and I also would like to know the answer! -
Mine’s OK :lol1:

mine wont cut a straight line down the middle of a 8×4 sheet?? its that bad.
-
OK, let’s be fair here…..
Sure, it is only a thin skin but we ARE trying to cut aluminium by hand and a lot of force on the cutting head is unavoidable. Sometimes I have to put all of my not inconsiderable weight on the head to get a cut started.
Also, the very action of cutting necessitates curling one side of the cut away from the other. Scissors on paper work in the same way – the right hand side of the material goes down under and the left hand side goes up.
Taking those factors into consideration I think it is unreasonable to expect an Excalibur to cut small pieces accurately and, for those who need to do that type of work, a guillotine might be a better tool for the job.
On the other hand, if your Excalibur won’t cut anything smaller than about a foot then perhaps there is a problem with it.

just fitted a new wheel assebmly. managed to get a straight cut (well not as nice as i would have liked) with about 1tonne of pressure on the clamp. Perhaps its not the best tool for the job?

Had a couple of phone calls from Keen-cut this week and they truly are very helpful. The first option they talked me through was to check the nylon bearings on the cutter wheel assembly and yes they were loose, this improved the cut to almost straight…yes almost straight…after speaking to them again I received an extra spacer for the handle today to move the handle across to the left so when you pull down the main weight is central to the cutter wheels…..and…….. :lol1: :lol1: .. it cuts straight !!! (hot) (hot) .
I was very impressed with their help and even more impressed it now works perfect..
