Want to convert HP Draftpro 7570 into a vinyl cutter.

[Helifoto]

Hello to all,

Today I converted a hp 7580B for vinyl cutting. Everyting works but far from perfect. Things to sort out...

1. Right pressure on knife
2. Relocate center coordinates after loading a paper
3. Finding some nice freeware. Signgo is great but only works for 30 days.
4. Try to make it all work under win XP (I had to use an old win98 machine to make it work)
5. Buy some new vinyl. I have heard that it gets hard in a year or so, thus harder to cut nicely.
6. Make some money from it

I am having issues with the paper feed. it seems that the feeder is slipping on the surface and therefore moves the paper/vinyl wrongly. Does anyone have this issue? Any suggestion how to fix this? thanks.

What thickness is your vinyl product? Have you tried to adjust the Platten pressure on your HP?

FattyJr,

Send Andy Fritsche an email, admin@fanet.de.

I found the German forum, translated the page and asked the seller to send me comperable info on the cutter holder & Blades. The seller is in the USA.

If I read your post correctly, nothing is attached under the pin holder. The HP pin holder to facilitate pen changes while plotting an image, is spring loaded. Since the drag on this holder will be greater while slitting vinyl the spring tension will tend to let the knife holder wonder, depending on sharpness of you blade.

Since the carrage is plastic, I used a rubber band to apply more tension. Just incase there is a wreck undere the knife, the rubber band will hopefully break and not the pen carrage.

I am new to the cutting end of the HP but have years of service plotting electrical & electronic dwgs.

i am trying to convert a hp7580b pen plotter into a cutter for sandblast mask material i have found some info on it but am curios at to if anyone knows if it will have enough torque to pull through the material, has anyone tried cutting thicker vinyl any help would be awesome

[coltons customs]

my material is a 16 mil rubber made for sandblasting i have cut it before with a graphtec plotter and a 60 degree blade however it was not my own and am now trying to figure it out i have a mimaki blade holder and 60 degree blade am using the demo version of sign go i am just trying to figure out if it is worth the effort to try to use this plotter due to the probs everyone seems to aquire in just cutting vinyl

[coltons customs]

i used a mimaki blade holder with a 45 degree blade for vinyl under 12 mil and aprox 2 ounces of weight i used a 60 degree blade for thicker stuff as for shimming up i used tape they use when installing pickup toppers and lay it in the crease on the cutting table that is directly under the blade

Could someone tell me what blade holder I would need???

I can find some on eBay, Mimaki (which was mentioned on the Luberth site, or a Roland which was mentioned.

I am looking at the tungstentec eBay store.

Any thoughts???

Also, I have read a lot about shimming up under the blade holder with plastic or tape; does anyone have a good pic of this???

Thanks

Does anone have drawings for a vinyl knife holder for the HP 7585? A friend cut out a sign for me and I am intrested in makning my old pen plotter useful.

i actually came across a dxl and an exl plotter a while back, but wasnt able to find software to run them, i did find a guy that converted 1 drawing for me so i could test the exl, so i know that unit works.. i'm not so sure about the dxl right now, but i would really like to be able to make my own blasting and painting masks, as well as my own vinal lettering....

anyone got any newer information? this 30 day trial and then $200 stuff is for the birds... i need something cheaper and faster...

[project5k]

well i worked on this a bit over the weekend, and what i ended up doing was dl'n a trial copy of the winline stuff, but i still couldnt get it to work, i'm not sure if its the mach3 driver, or the fact that i'm trying to use a parallel port, or what... there arent any serial ports on my machine... so i'm kinda stuck.. i also dont know if its supposed to be a null modem cable or a straight through...
