can anyone advise with D60 cutting problems?
Firstly, I’m really sorry if the answer to my woes has already been given, I’ve looked through previous posts quite a bit but I think my problems are a little different.
I’m not sure if they are linked in any way but here goes –
Whenever I cut anything, the first attempt will always ‘miss’ the first cut. It varies from a millimeter or 2 to anything up to 50mm depending on the size of the image being cut. If I’m lucky it will be on a straight line and I can do it manually with a scalpel. It appears that the blade does not go down quick enough on the initial cut. If I ask it to cut 2 or more of the same image then the 2nd onwards will be fine (apart from the next problem)
I think this is just general wear and tear / servicing, but the general accuracy is failing and it is getting worse. Where 2 cuts should join they can miss by up to about 0.5mm which makes peeling away the unwanted part quite tricky (sorry I don’t know the technical term for peeling away!)
Finally, not really a problem but a question about drawing
I use CorelDRAW 12 and WinPlot V6.7 and I was wondering if there was a way to get the cutter to cut certain lines in a certain order – I’ve had some designs go to the cutter and it cuts a line then goes all the way over to the other side to cut another line and then back again. It seems daft and slow.
Sorry for being a bit thick 🙄 and thanks in advance for any replies.

Check that the grub screw that fastens the pulley wheel onto the roller drive motor spindle is not loose. If it is it can cause free play on the rollers which can result in the cuts not completing properly (there’s a similar wheel connecting the drive pulley onto the rollers – this should also be checked).
There is a way to order the sequence in which the cutting takes place – this has been answered before but for the life of me I can’t remember how to do it 😕

as per what Phill says. But also check blade offset as this could also compound factors possibly.

HI dude,
i’m not certain on the first issue, missing a cut but,poor cutting, especially on fine detail might well be your cutting strip, if you can feel a deep groove with your finger nail then it wants replacing.
drawing in 12,
if you draw a line, eg, you made up a dozen odd shaped decals on a single colour, you want to add cut lines between them to aiid weeding… these lines will cut in the order, and direction, they were drawn so, that is probably your answer. hope that makes sense! basically draw as you want it to be cut!

Thanks for the replies 😀
I’ve checked the grub screws – all ok
The cutting strip probably needs replacing so I’ll do that.
I measured the blade with a micrometer and set the offset correctly which helped a little.
But I changed the blade in the process and now, instead of missing the first millimeter or 2 it misses a huge chunk of cutting 😥
If I set it to cut 2 of the same thing, then it goes off and makes all the right moves but above the vinyl in mid-air! It can be nearly 2 seconds before the blade touches down. The second version will be fine but its annoying to waste a whole cut.
Have I somehow put the blade holder into the clamp incorrectly?

I had exactly the same problem with an old D120 that I had access to (not mine). I tried all of the above to no avail, including re-installing drivers. In the end when I contacted Summa, they suggested a service, but given it wasent my machine, that was not an option. IN the end I kist placed a small square into the objects to be cut as the 1st object………….

cunning 😀 I like that idea, thank you.

missing the first part of the cut is usually a bit of grit in the electro magnet barral. which operates the knife holder.
you can sometimes feel it with the machine turned off gently move the holder down and up feelling for some courseness.chris

Chris,
If its the same problem I had then I think its a firmware fault with the machine, as every subsequent cut in the file was perfect. It was just the very first object that the blade did not move. If it was dirt ingress, then there would be problems with cuts during the whole file output. It was a strange one, and all I did was to have a sacrificial object as the first object cut in the series.

I had the same problem on my summa, it was caused by a little foam rubber pad about 4-5mm in diameter that the cutting head has in it. The head has a screw in it which meets the foam pad when the blade rises, after a while the foam pad becomes worn and sticky, restricting the free movement of the blade down but not up. It does not stick as much while vinyl is being cut as the blade is only touching the foam briefly that is why letters do not complete entirely as it only sticks a bit but enough to effect the cut. The first cut is always the worst as it has been on the pad longer and so is stuck more firmly. Clunky noises can accompany this scenario as the head releases suddenly and not smoothly also a clunk can be heard when the head rises as the screw hits the pad which may not have any padding left to it, mine had worn a hole through the centre almost. I will put a photo of the head showing the pad in another post if you want,

That all makes sense, wish Id known that before as Id have put a bid in on the machine :lol1:

You would have got a bargain then Graeme it looks like an expensive fault but costs about a pound for a load of pads(not summa) and half an hour to fix

That sounds exactly like the issue I have, it makes a big clunk quite often! I imagine I have worn right through mine.
I would be very interested to see a photo and of course where to get hold of replacement pads.
Thanks.

Was this ever solved?? And was the pic posted anywhere??

Actually, I have got an update on this. Sorry I forgot to post it up.
Turns out there are 2 different types of head and the type I have does not have the pad mentioned in earlier posts.
The problem of the missing first bit of cut is down to the magnets sticking. Its all very clean in there, no grit and now lubricated too with a drop of WD40.
The cheap solution is to put an element into the design to be cut first (a simple box is normally enough) to get the ‘sticking’ cleared before the design is cut.
The not so cheap solution is to buy a new head!
I’ve also bought a new ‘Smart blade’ from Harry at Edward Mathias which helped enormously with accuracy of cut. Harry was a big help in working out what was wrong with the head, definitely the chap to talk to.

I dont think my problem is the same though. Mine is missing the same sections every time.
I will try and photo the parts being missed .
