Re: Mission accomplished "license to thrill"
 
I like how you have managed to work with the PVC so well. I saw in one picture you had some parts made with a nice rounded corner. How did you do this? It makes a nice look.
Also where do you buy you PVC from. I have made some DTG printers out of aluminum but think a PVC platen would look nice. Especially in black since it would match the color of the printer. I would also like to try to make a scissors jack for the platen out of PVC too.
you sure put alot of work into this project :-)

heres a tip i haven't shared yet besides with bob.. the material i used is pvc type II high impact plastic.. therefor it can be solvent welded ie( plumbing glue) it just takes a bit longer to set up and your cuts have to be precise even the cut edges sanded smooth for good contact.. i suggest making a square jig;) for those not confident about the plastic welding..

i use the plastic welder because my edges dont have to be perfect the rod fills it.;) then i just sand the top level..

also you could build it from plexi ie acrylic,plexi glass lexan available at lowes;)..this can be painted with acrylic paint and will look the same or vinyl stickered.. the best part of this material is it is solvented welded also but its bond is instant.. heres the trick you use (mek) available at most hardware stores including lowes..lol:D its branded as a parts cleaner and its some potent stuff..lol (this is the main ingredient in most plastic glues) you will use it in its pure form, it has the consistency of water use a syringe or hypo applicator to apply the liquid to the pieces to be bonded, instantly becomes one piece make sure you have it in a jig no taking it apart (this is how fish tanks are made;)) what it does is disolve or soften the molecules for a second between the two pieces that are to be joined then it hardens intertwining the two pieces molecules ie (becomes one piece) its not gluing, solvent welding:)

additionally you polish the edges using a map gas torch..similar to the small propane torch just different gas... it makes it awesome...

P.S DO NOT ATTEMPT TO POLISH THE EDGES WITH ANY MEK PRESENT IT IS EXTREMELY FLAMABLE..

Jeff, I really appreciate your munificent diy information.

when the previous design using Roll mode, the PE status is always ON (means paper existing). But now if refer to your new idea in order to set registration automatically, if use Sheet mode, where and how to install and trigger the PE sensor ? I guess if fix the PE several inches below the original position to let the forefront platen to trigger ?

Yesterday, I try to test it in Sheet mode, but failed. I hold the PE sensor by hand, and trigger it when the APG running, however I got the Paper light flashing alarm. And I want to know if you could start to print without any error/alarming every time?

i will share this new method once i get my printer alltogether.. (the modification)

we have deceided to go with the belt drive...:)

allso what printer are you using? 1900? and what rip?

Re: Mission accomplished "license to thrill"
 
For diy dtg, I have bought two R1900, because for the first one the print head was ruined by me :-( and I bought the second. In the previous I use EK trial, however I reinstall my windows system last, now I just use the epson driver. I would reinstall EK later to try to test again.

ok..then you are set to go with the 1900...;)

you can do your testing with the epson driver, however you will need the rip...for sure.. you cant get a good print using the epson driver maybe on white.. but you need to use dtg ink.. the rip lets you configure the channels for colors-white etc.. its a must have.. and ek has a table feed adjustment thats incredible..

do you have the printer set up as a dtg? if so post some pics etc.. once you get that far i will explain what you have to do to as far as mods to get it to work doing auto res..(thats what i call it):)

this also depends on your setup (drive)

My first release dtg use the original friction drive, wood platen, original inks just for testing (sorry for my poor performing ability). Now I am building the rear and opinion drive, using PVC platen, and straight-line lead rail. When I finish the new version, I would upload some picture also.:o

good start...

which ever method you choose for the next version...make sure you have access to the platen path to attach a few items under the platen..so that they caan read and make contact with the platen..

i will send you a pm...;) see thats easy... contribute your plans pics-progression and get the info...

good luck!

THANKS, PHILIP..:)

you can find material anywhere on the net.. prob locally aswell.. i fab plastic for my job thats why i use it and it is extremely light.. i have more info on this in the build your platen- base from plastic thread...

i used black polyethylene on the new printer..very cheap plastic and machines well..

hi, i have a little problem with the paper sensor in the epson t1100. can i fixed? do you have the solution? thanks

oh, and youre a genius.....

Re: Mission accomplished "license to thrill"
 
Thanks for the reply. I'm liking the plastic idea for certain parts more and more. What thickness polyethylene did you use. Is there a certain grade I need to use so it's not too brittle. Do you recommend welding parts when there is a bend as opposed to bending. I saw one picture you posed and it had a very nice rounded corner. Can I get this with welding plastic. How do you cut your plastic? I have cut this in the past and had troubles both with it shattering and melting when I cut with a saw.

Thanks

Philip

Hi,

Do you have a link for the build you own platen out of plastic thread? I did a search and couldn't find it?

Thanks,

Philip

Hi,

Sorry for all the questions. Do you use the low density or Hi density PE? I know HD is very strong. I didn't know you could weld PE?

Thanks again

Philip

here is the link.... buid your own base and platens from plastic

I use HDPE high density PE... and yes you can weld it...

however any thing you put heat to has a tendency to bow a bit... so after you weld it-> to pull the bow or slight warp out use a heat gun , heat it a bit and presto back to square... its welding temp is around 320 degrees..

i used 1/4 on the base and 3/16ths on the platen.. i also use aluminum L channel to stiffen the edges underneath the platen (counter sunk and pop riveted to the plastic)... this setup is very light;)

hope it helps..

i abandoned the 1100 for the 1900... the 1100 only works in sheet mode..

the only reliable method is to set it up as the printer operates.. you will need a separate belt from the paper feed (asf motor to move the platen to contact the pe switch at the correct time.. the only way to hack these sensors without electronics is to design it mechanically around how it functions normally..:D:)

i think you would have a lot easier time going to the 1900..the hacks are much easier and its a better printer...with the ability to print white..
