Cutter leaving perforated line
Hi
My cutter leaves a jagged peforated type line when heading towards its home position, but only when vinyl isnt moving…
Its cuts angles ok and when vinyl is moving to it will cut fine but not when it cuts in a straight line towards the right..
When it does this its almost unweedable… Its like the blade and holder is vibrating in one direction only…
To stop it for now i have got the blade as shallow as i can in the holder and upped the pressure so the bottom of the knife holder is sat on the vinyl more firmly which has stopped it vibrating when heading to right in a straight line….
Your all going to probably tell me this is how it should be set up 🙂Thankyou in advance

sounds like dirt in the holder bearings, not allowing the knife to rotate correctly.
remove the blade and holder and blast out the dirt with some wd40, dry of and refit.

As Chris said & it sounds like a new blade wouldn’t go a miss either.

There are a few things you could try that might help. Firstly as Chris has said try cleaning the holder and make sure the holder is secure.
Make sure your blade is set right, it shouldn’t be far out of the holder at all. Not sure what plotter you have or what software you run but I get my blades from Edward Mathias and they are already set up in a holder so I don’t have to worry about trying to set the blade at the correct depth.
First one costs a bit extra because you have to pay for a holder but after that they are cheaper that the original Graphtec blades.
Make sure the pinch rollers are set in the correct place to stop the vinyl rucking up in the middle.
Try and reduce the number of nodes so the cutter doesn’t have as much work to do.
Finally try asking the supplier of your machine about the problem as they may have come across this before with other customers. -
Hi
Thanks for the replys.
The holder is clean and it has a new blade, i did have it so the blade was out about a 1 mm and the pressure was at 45-50g, but now i have sunk blade so its probably 1/4mm and pressures upto 85g and it seems better. Is the latter the proper way to set it up anyway????
Its a Japanese Foison C24 610mm…
To be honest its been a cracking machine…..It doesnt vibrate/perforate vinyl on curves or heading away from base only heading back in a straight line… well saying that its not doing it now i have adjusted it….

The blade should be set so it cuts through the vinyl but not the backing paper. Best way to try and set it so I have been told is to take the blade holder with the blade in it and pull it across a bit of scrap vinyl. If the blade cuts through both vinyl and backing paper it is set to deep and should be adjusted until it just cuts through the vinyl and marks the backing paper very lightly but doesn’t cut it.
As I said above I get mine from Edward Mathias and they come already set up so I don’t have to worry about it. Might be worth calling them to see if they do blades for your machine as they cover most makes. -
Cheers Martin….

It can also be the platen strip. The strip gets damaged because you forget to reduce pen force after cutting reflective with dull blade, then vinyl with new blade…. – or due to prolonged use. On our (Jaguar) cutter it does this when cutting Rubylith, which is cut with minimal force (20 grams or so) I solve the problem by reducing the cutting speed to 90mm / sec. Don’t know if you can get platen inserts separately. Used to be the case many moons ago with the old CAMM1
