Summa Cutters

can anyone help my plotter is not cutting properly?

Posted by Kev Dunn on 22 January 2008 at 13:33

Hi All,

I’m having some bother with my Summa D60. I have attached a photo below…

The machine is leaving some parts of each letter un-cut. So its a real pain to weed.

I’m doing alot of these stickers and it’s not cutting the same bit on each letter every time.

Summa D60 with Corel Draw and cutting Oracal 651 and 751.

It doesn’t change whether it’s a new blade or not…

Anyone any Ideas?????

Thanks alot guys,

Regards,

Kev.

is your cutting strip worn? can you feel a groove with your fingernail?

Hi mate,

Yes there is a slight groove…

Could this maybe be the problem. How do you change this?

do a search for signwizard on the net, I am sure they sell these machines and will have spare cutting strips, better sill ask them about your problem

Looks like blade offset to me too.

Also check the blade holder to make sure the bearing is moving freely.

Hi Guys,

Thanks for the suggestions.

I have adjusted the blade offset (as per manual) to get the squares perfect.

I can spin the blade 360 degrees with my finger tip.

I swapped the cutting strip from side to side.

But it is still the same.

Any more Ideas?

Regards,

Kev.

It may be possible that the machine is taking the offset instruction from the cutting software, there is usually an option to take the pressure and other settings from the software rather than the plotter settings.

I dont know the summa, or your cutting software? so I may be wrong but worth checking.

Check there’s no free play between the motor spindle that drives the rollers and the sprocket that is attached to the drive belt. My Summa d610 once had a similar problem and it turned out the grub screw that holds the sprocket onto the spindle from the motor had come loose allowing a small amount of free play between the rollers and the drive motor.

the point where the faults are is the start and finish points of each loop. all other courners cut ok.

so phill may have a good point, or the vinyl backing is buckling, or the pen down is lazy.

I think there is an "overcut" setting in the summa cutters display panel. Check if the endcut is indeed overcutting the startcut

Just an idea

I heard of this quite a few years ago. It was down to the initial setup of the machine having been altered.
Have a look in the manual for setting it up from scratch.
