Thanks

No gears needed. Size unimportant. Just a idler.

DrDeath, what did you use on the idler wheel for a set up? Like the PE switch seems simple and good along with the drive rod. Good job! GO MAN GO! Im in and out all day won't have much time to work on the project so im way behind you now. My little ones have softball practice. Softball pitching practice, dance recital, school, homework. Then I can get in some R1900.

Hope they win :D used blocks of mdf wood cut to size

Thanks for the pics. Looks good. Did you use a bushing thru the wood for the drive rod. I found some plastic type bushings. Remember the coating on the rod is by definition abrasive. I polished mine with the same metal polish I used to take off a few 10 thou for the coupling. I also spent some time sanding any area that could contact the pe sw.

Will fine tune when assembled.
Can't wait.

Thats what was killing me was over thinking it.

I need some information from anyone and everyone that can and will check out the weight of everything nthat the drive rod needs to move. What does the platen weigh? What does the tray/drawer weigh? I am real worried that I'm making a setup that has such a great mass that the paper feed motor won't be able to get it to move and/or stop properly. Just the sheet of aluminum and the two aluminum angles with the drawer part of the slides weigh about ten pounds.

Re: The Journey R1900 Build
 
I understand your concern for weight, but just remeber your motor is not trying to lift the slides and the angles or the platen box.

Instead you are moving it and out, when you have it setup just push the platen box in and out to see if there is any resistance, to be honest the friction from the whole setup is very little so dont worry!

Re: The Journey R1900 Build
 
I know I've done everything reasonable to reduce friction in all the bearings and drawer slides but I'm worried about the moment of inertia. (if I said that right) I may have misunderstood the service manual but there is a system set up to measure "resistance" in the drive setup through the electrical voltage draw to detect things like paper jams. It would be a great reasurance to me to know that I'm not as heavy as most others at this point but I'll know soon enough I guess.
I'm slowed down a little because I used a slow setting epoxy to attach the aluminum angles to the aluminum plate that is the tray/drawer that I'll place the shirt platen in for printing. I knew it was a slow setting epoxy but I thought I'ld be setting the angles on both sides at one time but I couldn't find enough clamps to do but one side at a time. But I still believe in J B WELD.

Check the platen box is level so its not pulling uphill and the weight not a big issue unless out of control.

ok now i am confused,not sure what this plugged into. Maybe something i removed.

Not sure what I am looking at. If it a cable that runs off the power board it could be the high voltage cable. Hooks to front of mother board. I trashed mine. Did not use.

Re: The Journey R1900 Build
 
I don't think ya'll are understanding what I mean. Its like you have this barge setting in the water. you push like all get out but it resists. but with the same strength, it starts moving slowly and needs less strength to keep it moving. That is what I understand as "the moment of enertia" and where the voltage difference between what it needs to move this heavy thing and the voltage(strength)it shold be using to move a sheet of paper, assuming it will look like a paper jam because something is causing the drive rod to need more power to be able to turn. I can't think of anything that would normaly be put through these things that would weigh even 1 pound much less up to 20 pounds after adding the platen and shirt to the weight of the tray.

spiderx1 March 24th, 2011 07:05 PM

I understand. And agree it should be as light as possible. But the motor is quite strong. The weight on some commercial machines is far more than yours. On my Tjet 3 I stripped 7 lbs off of it in just trim. Thas just a small portion of the weight. If you can move it back and forth easily with one finger you should be fine. I think the tension on the belt is far more taxing on the motor.

It runs from the other side of the printer the other plug goes into a motor on the upper right side

Ok, got to this point. Seems like it is working. Cyan ink out no biggie, now have to make a platen for the shirt..

Nice job! can you do a video showing all sides? Pan from one side to the other? I am striping down now and would love to get a look!
