after extensive research and development, I'am in the process of adding a micro controller to the epson 1100 workforce, which can work with the 1400 as well.. this mod will control the timing of the factory epson sensors (esp)..the pe and apf sesor control timing. to allow the removal of the apf motor and tray completely. this will eleminate the preprint dance using the apf motor and wheel on the mods, and allow for repeatable platen results with a properly designed platen. just load and print basically. i will incorporate a line sensor for platen for repeat prints for accuracy (like white base and then color over) we are in the programming stage right now and within the month should have a working unit to test..at that point we will post videos...i'm confident this will allow many to enjoy a low cost dtg or diy dtg printer using this hardware.. :)

see also some useful info in the 1400 mods thread relating to pw sensor (timing and printing pe and apf sensor) the 1100 will print with no paper. pw sensor is not looking for paper it looks for location explained in that thread. pg7

Just a quick update on the micro controller....
just got a call from creative circuits he said i should have a finished hard copy in my hands by april 8th. at that point I,m going to run it about a week. then ill post the videos of the unit and plan on making it available shortly afterwards. i,ll have about 45 units starting out because 50 units is the minimum order of boards that they will print and im going to hang on to 5 myself. If the response for the sale of these is good ill reorder them 50 at a time. it will be first come first serve. i will make them available on ebay for the first 45 and if i continue to sell them i will open a website from there out. ill post a release date after i post videos. just keep a watch on this thread for info...

happy printing

just wanted to update on the micro controller. the board is in its hard copy state as of this morning my electronics engineer will be transferring the program to it as well should have it in my hand tommorro, im behind on my fabrication of the unit itself due to dealing with the electronics. im about half way into the process. additionally im waiting on the carts and dtg ink i ordered along with my belt and drive pulley. im going to post it up when the unit is complete and printing, thats the only way to truly show the value and debut the unit (working) so bear with me. should have something with in reasonable time, and im sure there will be a million questions just trying to get my ducks lined up.

thanks jeff

gotta post the good, bad, and ugly.

heres the ugly
did first print test with micro-controller. just on paper, unit not connected to platen yet. the micro-controller was programmed at the epson print default settings (letter 8 1/2x11") opps:( settings should have been changed to (super b 13x19 thats the platen size) so she printed great just not the right size. some of the programming timing has to be adjusted to coordinate the correct size..;) so hes back to the drawing board...i guess it cant all be good all the time!

i,ll keep ya posted:)

thought i would post a pic of the proto board (micro-controller). this will give you a general idea on the size, it is cut to approx half this in its hard copy. the picture doesn't show with its wires soldered to i/o ports we used a plug n conector for the testing. the tiny holes are programming ports. its a pretty good picture of the processor(micro chip brand) there are three different processors we can use atmel, intel,microchip i will just use the cheapest one at the time of reorder. they all are well known and of good quaility and has its clock etc internal. as you can see even the proto board is a pro print. i,m still looking into the possibility of adding connectors so it will not have to be soldered-depends on its cost. i'm trying to keep this as low as possible. i have already got a couple rolled eyes at its price currently. i will update on the progress:)

Agree connectors will be better much easier and it won't jeopardise the whole epson motherboard if you miss solder it.
none of the connections are to the mother board itself. i agree for ease of install connectors would be the best choice, however again that comes down to cost and time to apply them...:)

let me rephrase that...it essentially is to the mother board but to existing leads out.;)

hey german is your machine working???

i´m curious about it...
the machine is definitely working.:) we are working with some eleventh hour programming tweeks (the controller is professionally manufactured. we are also working on a website for the kit products (i have partnered with a fellow diy,er on this) those details will we released by him upon inception,i will debut it with a design in plastic that my company developed, German mechanical design.(the platen base) we are wraping up on that as well, its precision guided belt drive, (actuator style) for the motion control. this i will make available along with the micro..

just keep an eye here or subscribe to this thread for the released videos in the near future.:)

thanks jeff

just thought i would post an update on the microcontroller...we are getting very close to a finished product.. here is a pic of the controller with wiring to give an idea..:)

this is still not the final, final will be green:D just like most every other electronic board you see, but wiring will be same..

will post up vids on completion..
