I have an older pnc 1210 cutter. I was wondering approx, how many grams of force you are using if you have a cutter like mine. I used to cut sign vinyl - cast or calendered somewhere around 40 grams. I have had to increase the pressure to over 100 grams lately. At 40 grams the knife doesn't even seem to make it to the vinyl. I wrote Roland techs and they replied that 100-110 grams is normal for sign vinyl. Am I loosing my mind or is that way high?
On another note: has anyone been able to get one of these to work with X3 and Vista?
Thanks for any input.
Brian

Just a suggestion Brian...What kind of shape is the teflon cutting strip in? Have you ever replaced it?
I found that I had to increase pressure as the cutting strip got worn out.
It sounds silly and simple but replacing that strip made the cutting process more accurate and required a lot less pressure.
(Hated it when I had a brand new teflon strip installed, increased the pressure for reflective, forgot to decrease the pressure on the next cast job and tore up a nice gouge in the strip!!!)
If you can see a "line" or gouge in the teflon strip, replace it. But remember to back off the pressure after that and do some test cuts!!!
edited to add..your unit is good from 20 grams to 350 grams downpressure without damage to the unit so 100-110 is probably OK. But if it used to cut well at 40 grams, why not try the above suggestion?

Get this.... the old Camm-1 Pro in the "old" office is set to 190. It cuts fine at that. The Mimaki CG I use 99% of the time is set to 095 for calendered and 090 for cast. 110 reflective.

Dave, I checked the wear strip and it is in great shape. During my "closer" exam today I noticed that the knife wasn't lifting very high either. I took the spring off the carrier and noticed the movement up and down was sort of dragging. The rod had what looked to be old white grease (lithium maybe?) any way I cleaned it up and WD'd it. After a few cleanings and sprays it freed up a lot. It is still taking 150 grams of pressure to cut vinyl but it's working better. Now it at least touches the vinyl at 40 grams.
Mr Dalton - Thanks for the input. I too use a Mimaki for most of my stuff - and I cut at 50-70 for everything. I use 130 for cutting thermofilm and flex.
Thanks for all the input - I still think something is not just right - I am going to keep fiddling with it.
PS: Anybody ever "oil" or "grease" their machines at all?

DO NOT OIL OF GREASE IT........it aint an automobile!!! the slide where the blade goes up and down clean with 91% alcohol, see how it works. if it seems to drag, 3 in 1 OIL ON A Q-TIP, VERY LIGHTLY, now rub the q-tip on the up and down shaft. you might wnat to check the SOLINIOD, only if your a good mechanically!!!! the sometimes will lose tension as they get old.also takin it apart and clean internal coil might help..ONLY IF YOU KNOW WHAT YOU ARE DOING!!!!!!! when i had 2 PNC-1100's they both worked fine between 70-120........depending on the vinyl.

FIXED! - I now have it cutting great at 70 grams.
old paint: The shaft had white grease on it and it was sticky. I used the WD to clean and loosen it... then I cleaned it all off the best I could and applied a small drop of sewing machine oil. Wiped off all access. I also oiled the bearing in the blade holder. Seems to be cutting good. I still think I cut with less force than this. Older I get the shorter my memory gets.
Back to the cutter - to make sure I'm not dreaming!
Thanks again.
Brian
