My multi-cut is off

My multi-cut is off

Postby Esther » December 5th, 2017, 10:53 pm

Hi all,

I'm cutting 0.8mm chipboard using a 60 degree blade and the clickholder and my multi-cut (2x) is not following the exact same path on the second round.

On the horizontal sections of the cut, it cuts in a slightly different place. It seems to be doing this where the shapes have long horizontal cuts. The vertical sections are fine.

Any ideas what could be causing this?

Hi Esther -

Is there any chance your mat is buckled in those places and throwing off how it lays on the mat so it is effectively "shifting" a little when it runs horizontally? I know you are an experienced cutter so sure you have your blade settings set properly for the blade.

Just out of curiosity - have you tried the 60 degree plus blade that usually does a better job on chipboard. I am trying to think of why your vertical cuts would be fine but your horizontal cuts off. Do they start off at the beginning of the cut or do they move as the cut progresses? What force and velocity are you using?

Have you tried to draw the pattern with the pattern twice consecutively to see how if it looks accurate with the pen tool. That would help narrow down the options of what might be going on. Just a thought.......

Gigi,

Thank you so much for your answer.

My mat is most certainly a little warped, but I rotate it often and can say with some certainty that at least some of those cuts are falling in flat sections of the mat. But now that you've alerted me, I'm going to pay attention to the location of the cuts and extent of the double line on my next go. Brilliant suggestion, thanks!

My new order of 60 plus blades just arrived (the ones I have in stock are dull) so I will try with that.

As to the location of the problem cut, it seems to be on opposite sides of the rectangle so if on one horizontal it falls on the top left the on the second side, it would be bottom right.

My velocity is about 400 and the force 200. Blade extension is approximately the same as material thickness and blade height is set with the felt gauge that shipped with the machine.

One more thing I noticed, the problem does not occur on curves or complex cuts, just on the long horizontal straights.

Trust me to get the weird problems :D

Thanks again Gigi, I hope the added info will help you think along so we can get to the bottom of this problem.

I have appointments this morning but will think about it when my head is clear? Did you try cutting the same design on regular card stock? Just tryign to see if the chipboard and blade are the issue vs. something else.

More later........... :)

Gigi, the thing is I have the thicker material which needs multi-cut and then the thin kind where multi-cut will likely eat into my mat. Let me see if I can find a different thick-ish material where I can try the multi-cut and let you know how it goes. Just to confirm, the regular 60 blade offset is 0.25 right?

Thanks,
Esther

Yes - the regular offset is .25. for the 60 plus it is.7

On the thinner material, just decrease your force so two cuts wont cut into the mat and do a multi cut - that should work and hopefully help us problem solve?

Gigi I'm thinking the problem is with my click holder. It seems to cut fine when using a regular holder or the detail holder. I think the holder is slightly out of alignment. It came apart once while I was changing a blade/cleaning it and though I put it together again I guess it's not quite the same.

When cutting chipboard, due to the sturdy nature of the material there is more pressure on the blade and as the holder is not 100% OK this shift happens.

Does this make sense to you?

HI Esther -

I am not sure I have heard of a click blade coming out of "alignment" per se, but they have malfunctioned a time or two - usually at the beginning. But I totally understand what you are saying and the fact that it cuts fine with other holders definitely leads to that one being the culprit! I am glad you figured it out - thank you for taking the time. I hope that totally resolves your issues.

So much for cleaning -right??!!?? :)
