my white ink is reborn! i took the day off. only to get back the shop with white ink acting up. not intermittently but every three to five feet it would drop. i've noticed that the white heads just can't reach 49. even if i set them to 52 (the max), they won't get to but 47.6. so i...

@mrnick86 i get what you are saying. our gantry is dead on 90 degrees all the way down the table. i'm going to shoot a video of my pully behavior. maybe if you have a minute you can look at yours and see if this bouncing to a stop is normal. @gino the replacement motor is the same motor...

this one has me really confounded. we have this issue lately/permanently where our prints are stepping to the left about 1/8" per every two feet. the bottom and top of the print are perfectly plumb to the printer. (image attached) the encoder reader was cleaned, then replaced, the encoder...

great advice bovegas. also if you hear a hissing noise have a partner press upwards on the capping station into the print heads while pulling a vacuum. if you hear the hissing noise get quieter or go silent then you know that your caps aren't targeting your heads either most likely high...

awesome update david! you have a lot of CET fans here including me. we can never be too updated/informed.

with rasterlink it's very easy. keep it in CMYKlmlc/ -SS. you'll need permanent chips for the lmlc. now just run a CMYK profile and it will print from the two heads. you'll need heads plugged into the lm lc. you' can use old clogged heads and just run homebrew cleaning solution through...

so that explains why we never seems to get the white advance. i hope there's some technical reason beside just having lazy programmers. also, when there's a narrow spot that with most printer would have the carriage jot back and forth quickly, the carriage still swings the full length of the...

so if there's white ink in the profile, it will skip white space? or white ink in the ripped print file? all of our profiles have white attached.

in the firmware under sytem, there's a check box "skip white at blank space". but it doesn't seem to work the same as on most printers. it seems to do it occasionally on the margin. maybe there's something about my file that is causing it not to call it "white space"?

i purchased a small enexpensive led uv way back to test for curing and i found that a fluorescent black light put out more joules than the "uv curing LED". the type that is needed for curing will be a pretty beefy lamp with a power supply. when i got back to the seller (uvprocess) they...

it'd be great if the existing power supply would work for a new lamp system. then as well the light would have to be the same. it seems that the ink would be formulated for a very specific wavelength. here are some curing units off of alibaba that might do the trick for a real system. keep...

i'd go for it. you'll be able to come up with lots of of work arounds from cutting one letter at at time, to feeding panels through with tables on each side. 4' wide anything will not be terribly limiting. as for accuracy... it's a sign, not a machined part or a cabinet. just cut the damn...

any cnc, the worst most accurate cnc is better than "no cnc". i'd get an old school shopbot if i was getting into the cnc game. huge user support on http://www.talkshopbot.com/forum/, i've been able to fix my ancient one here and there with minimal technical skill. if you can pick up a used...

is there any ink leaking just below the tubes that enter the yellow head?

i think the thing is to print a negative black mask on the emulsion, expose, and this wash out the screen. the ink should slip off with the unexposed emulsion.

i've seen those systems on alibaba here and there. seems that many of them print some kind of solvent. i've considered messing around with it for some very basic screens for art production. i'd assume you could just use several coats of uv ink as the resist.

when you say "condense" you mean wicks? condensing would be from the rapid evaporation of the solvents in the ink, which the uv ink does not have. also what are your settings (heat, voltage, negative pressure)?

the plot thickens of course this is a thread about y- position. i didn't get to it today because we were dealing with another issue. but i noticed something odd concerning the y- start position. i needed to run a test so i sent the print. i saw that it didn't go to the "main" printing...

i have the used 6x10 fk512 for several month now and it's been a great machine. except for one thing that has me puzzled. my "zero" (aka flat y-base in the control panel) isn't consistent. this has been happening since our install. but recently has gone cater-wonky and i find myself watching...

the negative pressure is just like holding your finger at the top of a straw and then drawing it out of the fluid. it will hold the fluid by vacuum. by lightly lifting your finger away from the edge of the straw a small amount of fluid will escape. adjusting the negative pressure (odd use for...
