Anycubic Photon

Took advantage of today's lightning deal, my printer will be here Sunday.

Dang man. Got to be about 10 here alone.

Not Photon news, but I got the brass Shapeways parts in today.

They look great and came in a little felt baggie with a draw string  Now I just need to order the corrected version...

Yeah, probably because majority of items printed in this material are jewelry, so they come in gift bags. 

While I enjoy reading this thread, I wish some of the stuff mentioned here (in almost 800 posts now!!) would have been covered in separate threads.  This is one crazy free-4-all!

Did my first print off one of my models, my SD70ACC cab and inverter cabinet. I think it turned out pretty good for my first time.



My settings:

layer height: 0.02
bottom layer count: 8
exposure time: 7.5
bottom exposure time: 40
light off delay: 1.5

 Reese,
 Looks great.
 Change the off time to 6.5 in your Photon slicer, cause that is the minimum amount of time it takes the "Z" axis to cycle and cause the "print time" to be wrong when the slicing is done.

Looks good Reese. 
I'm sure this was just proof of concept, correct?
A couple of questions...
Not familiar really with the prototype, are there vents, grilles or doors that you plan to include in subsequent designs?
Is there a way that the bottom, where it meets the sill can be more straight/flush?
It looks a little wavy, is that where the supports were trimmed?

Yes, this was pretty much just a test to see how it would turn out on the Photon.

The prototypes are rebuilt SD70s to AC traction, wide cab, ect.



The louvers on the doors all turned out well but the vents on the inverter cabinet look a little fuzzy but I also think I made them a bit small. The details are a bit to see anyways on this green resin, and my quick cell phone shot didn't help much either. I'm going to give it a coat of primer tomorrow so I can fully inspect it.

I didn't do much finishing on the model other than cutting off the supports, but a little sanding should square up the bottom nicely.

I'll do some more testing during the week. I think I'm on the right track so far.

Thanks, that all makes sense.
NS must be really powershort a lot of time.
It's amazing to me that they would shop that unit to do plastic surgery at the front and completely ignore the tail.
Presumably they would do this surgery at the time for overhaul and yet they still don't paint them?
Weird.

These were probably shot after overhaul work completed and on their way to Juniata shops for paint.

Weird.

IIRC the SD70ACC rebuilds are done by Progress Rail in Muncie, IN or Mayfield, KY and shipped back to NS at the Juniata Shops for final painting by NS.  Most are transferred in this ragtag look.  NS currently has over 600 older locomotives stored due to implementing "Precision Scheduled Railoading" so no real shortage.


Here is the 1800 after repainting (3 months after the previous picture):

Ah, thank you for the additional info.
It seemed I had seen pictures of fresh GE units pressed into service in primer but I can't be certain it was on NS.

Congratulations!   Some gray primer will bring out the detail and I'll bet it will be impressive. 

Rod already mentioned setting the off time to 6.5.  It won't change anything you've done this far because that's what you had anyway.  It's the time it takes the machine to cycle up and back.  What it does effect is the estimated cycle times as they are calculated from the setting inputs.  The number you put in will give a time estimate much quicker than you will actually get.  By 5 seconds per layer.  When you put in the 6.5 number your estimates will be very close to the real time.

And don't hesitate to try .05 layers.  They print pretty nice too, and a lot faster.  The normal time should be increased to 10 or so if you do that.  I successfully used that with green resin.

[Chris333]

I think .05 layers give you less sagging as well.

After recieving some stuff from Mark W, I want one of these printers even more. If it wasn't for the fact that I have a hard enough time finishing simple projects (no problem STARTING the projects, just finishing) and know that learning new hardware AND software is probably not going to happen I continue to hold off. His parts look GREAT however. Better than SWs parts...
