Do you have a Rep2X? Are you using photoshop? No?

Why not?!

Yes? Have you tried this yet???

[Steve Johnstone]

No way!

I've never seen the value in dual colour printing and have use my R2X more for dual material printing.

This is a serious game changer!

[Andy]

That is awesome! Can I do it with my rep1??

[TRAMMALOT]

which version is this?

[Rich Webb]

Hmmmm. Zoom in to, say, the gray area below the Mist logo and look at the woven pattern, with alternating warp and woof threads. A "canvas" filter in Photoshop? A well done effect but printed? My guess is not.

[Ryan Carlyle]

What?! How the...?

[TobyCWood]

Oh yeah... it's printed... Off a rep2X. I added another example made from a photo.

I'm trying my first print right now off my Rep2. They have their own approaches to... everything!

Output for the 2/2x selection is x3g. It will print to disk or print via USB.

The can was shown to us during our interview with Adobe.

You can get a free 30 day trial of the cloud version and they tell us there's a $10 a month package with access to the PhotoshopCC version. The CURRENT version has all the 3D Print stuff in it. It has since August. I trying the trial right now... It's good old PS! There's a 3D Mode now and a couple of 3D Print menu items.

Somebody with a 2X... GET IT AND TRY!!

The profiles are the 2/2x bots and ll the online services and a bunch of high end industrial machines... BUT! Go hunt for it on the website and you will quickly find they opened how to set the xml file for making your own profiles. I would BET a Rep1 profile would not be hard to do. I got a lot on my plate right now or i would dive in.

So far I cannot see how to change my temp so I assume it is a property setting in the xml profile.

The interview was a stunner. They had no knowledge of this community... we were shocked at what we were seeing... and hearing. They voxelize the object before slicing. Bye-bye Netfabb. We found another small company from Poland doing this too at the show, but Adobe?  Look out!

Printing the 3D Knot in Protosupply blue. Looking super fine right now. I will post the finished object.

While our moderator knows this already, for others you can work around
this one of two ways

1. Run it on a Sailfish bot and use gcode temp override, or
2. On any bot which supports changing the temp whilst printing (Marlin, Sailfish, Repetier).

Problem with Marlin and Repetier is that the gcode generated by PS will be
MakerBot-style and not RepRap style.

Here's the completed 3D knot. Note the support structure...

No idea why only one, but the other 2 arcs did not need it.

Not too shabby. Would I stop using S3D to go with PS? Probably not, but voxelizing the object before slicing is a VERY good thing.

[Jetguy]

Interesting and very cool, trying it out myself now.

Quick question, was the printed fake soda can an example file? Just looking for a quick model to try out those features on.

Just curious what files you imported and so forth and if they can be shared?

[Andy]

Thanks for sharing .  This is really fantastic.  I backed the kickstarter for that other software you mentioned, and I'm still waiting.  Nice to see adobe put their RnD to work on this and make it real.  Does it use purge walls or a sacrificial tower to keep the idle nozzle drool off the print ? 

Is it possible to use a normal map to create 3d texture on the model surface ? 

I might need to dust off the rep1 and make a profile for this!

-Andy

[TobyCWood]

The can was printed by Adobe. My bet... get a photo... a grayscale photo. Then I believe you use it as a cover or wallpaper onto the shape. From there i do not know. 

Sorry... I have a client screaming for a scan and I'm currently crash coursing on Photoscan.

[TobyCWood]

Go to preferences... experimental features... enable multi tone...

Been watching one of their tutorials:  https://helpx.adobe.com/photoshop/how-to/prepare-print-3d.html?set=photoshop--whats-new--2014-10

The narrator says "notice the walls have been thickened…" If it's smart enough to do that well, that will make it a lot easier to adapt a complex 3d model to 3d printing.

The selection of printers shows Makerbot 2, 2x, 5th gen., MCOR, Zcrop.

So, I have the photographer's subscription (Lightroom and Photoshop for $9.99 a month). I had checked out the 3d printing options a few versions ago, and it was kinda limited. Plus, at the time, there was no indication that you could put in a new profile for the Rep 1, so I didn't really mess with it.  I was playing around with it just now, and their support system is wacky. If I can get a good Rep 1 profile knocked out at some point, I'll have to give the halftone printing a shot.

[Brandon Andrzejewski]

Has anyone had successful results printing images onto solids yet?  Once work is less crazy busy for me (this is the equivalent of a "Free Beer Tomorrow" sign) I intend to grab the trial of PS try this out on our R2X.  But who knows when that will actually happen. 

[Bonekollector]

I was playing with it last night -  I wanted to try out their supports but was disappointed that it didn't seem you could output them to an stl... did I miss something.?

[TobyCWood]

It outputs x3g for Rep2/2x. You can also output for Objet(Zcorp), Mcor and for services like shapeways. No gcode. No stl.
There's xml file mod capability so we should be able to get Rep1s and clones working too...

I just got so much to do...

[Jetguy]

I'm on that quest too. In fact, this "It outputs x3g for Rep2/2x" is why I switched my Wanhao Duplicator 4 to 18t timing pulleys on the X and Y motors so it's now effectively a Rep-2 and 2X compatible machine.

What I'm finding is there are a LOT of programs and even MakerBot themselves are promoting/supporting only the 2 series profiles. A shining example of this is the MakerBot digital store.

I ran into an issue where a model I bought was missing a single part file for the 5th gen mini (yes, the store sucks and has tons of stupid mistakes like this) and to complete the print, the only way was to either wait for MakerBot to fix the problem and provide the file, OR, do what I did and swap in 18t pulleys (only required on the X and Y motor) and then I could print an X3G designed for a 2X on the Duplicator4.

I'm just saying, for those with Rep1 clones, this might be a better long term solution given market trends and things I keep seeing repeated in the software. Rather than fight the system, it's a cheap and easy mod- then no software hacks required. Again, think of it like this, there may be multiple new software tools coming out that natively support 2 and 2X profiles. Rather than having to hack each application individually to get a working Rep-1 profile, it's easier to just swap in 1 pulleys and now no software hacks are required.

  I just finished the tutorial mentioned above & if you choose local printer in the properties window it gives you the option to export to stl then all the other printing options - layer height temps etc can be handled by the slicer/printer software as before - I have a Rep1 Dual & I just opened the PS generated stl in makerware & it opened/sliced OK (I have'nt got time to print it now but I'll try tomorrow. I haven't tried a supported object like the owl above but part of the questions being asked is solved by the ability to export stl's.

That's  great answer but one giant thing we should address here is capabilities.

The draw that brought me into even trying Photoshop was the dualstrusion capabilities that are shown in the original post.

Let's face it, there are so many CAD programs, so many free tools, and so many slicers all for single extrusion. We don't need yet another CAD/Slicer combo.

But, what I saw was some impressive dualstrusion features NOBODY else offered. That requires direct slicer integration to get those results.

As such you cannot export an STL file that I am aware of (because there would minimally have to be 2 STLs) to export the photographic dualstrusion print function.

And sorry if that's just my focus but again, why in the world blow huge money on Photoshop just to export a single color STL. That is pointless.

I'm not saying that there are not cool features and there may be functions here not offered but in the single extrusion world, I think it's going to me really hard to justify to the average 3D printer owner.

On the other hand, guys producing models to sell where Dualstrusion with real capabilities beyond the basics that we get from Makerware could be a game changer. Those folks can justify the cost of Photoshop in the business model.

[Jetguy]

Again, what impressed me is the grey scale dithering present on that simple print of a soda can mock label.

That's not faked, I can see the overhang droop on the bottom edge of the print.

To be able to take a cheap Flash Forge or Wanhao dual extruder machine and get that print "they think" they have locked into an expensive Replicator 2X only function is why we have public groups like this to break down those artificial barriers. The combined knowledge of the group and understanding of software and hardware is what this is all about.

That's why I'm trying this, I think that is cool and want to unlock that feature for others even though I don't own a 2X.

[Darrell jan]

Jetguy,

So for a Rep1 Dual, all I need to do is swap in 18t pulleys? And, for example, tell S3D to use a 2x profile?

[Ryan Carlyle]

And change your machine definition so the firmware knows the new steps/mm. 

[Jetguy]

Yes, and specifically on the X and Y motors.

 

X is simple, it's direct drive off the motor. Y axis generally has the short belt from the motor to the jack shaft. The key here is that both the drive pulley and dreven pulley on the jackshaft are the same. They could be any toot count, it's a 1:1 ratio in and out. So by changing the pulley at the motor- the source of the motion is now 18t pulley.

 

You cannot connect with Makerware and print over USB this way as the Makerware conveyor service looks for the reported VID and PID of the firmware to decide which bot you have. Rep-G doesn't care about VID/PID but you should connect one time using the Replicator 2X profile to set the correct steps per mm in the firmware. Remember, for the most part, the magic happens at X3G conversion step. However, most Rep-G start.gcode recalls homing offsets as does the S3D code. Setting correct steps per mm in firmware is used for: Homing and toolhead offsets and the real kicker- pause of any type.

 

So the basic steps recap:

Change pulleys

Connect to Sailfish using Rep-G with a Sailfish Replicator 2X profile- that adjusts steps per mm in firmware eeprom and updates the axis lengths and homing/toolhead offsets. Keep in mind, firmware thinks in steps, not mm. This is why this is critical

Now ensure you choose 2X machine types in software when generting the X3G so that the correct steps per mm are encoded to the resulting file.

It's recommended to just print from SD to prevent any confusion. Any previously created X3G is proabably encoded with the wrong steps per mm and thus a smart idea is to purge all SD cards of previous files.

 

Again, the advantage of doing this is so that things like The MakerBot store which sells X3Gs that are precompiled for the 2X would print 6% undersize before this mod. Things like MatterControl currently default to Rep2  profiles for X3G, etc.

Rather than fight the system, make a simple mod to the printer and just fake the funk.
