This is my third review of MakerWare. The first. two. reviews showed the software to be promising but beset with enough problems so as to be unusable. Some problems persist, but the usability’s taken a big step up.
The biggest change I’ve made to my setup is upgrading the Replicator Dual’s firmware to the most recent version. This fixes the MakerWare connectivity problems I was having a month ago, and also makes the Replicator quieter and faster. I jumped from 5.4 to 7.2, and frankly I’m kicking myself for not doing it sooner.
I’ve started aiding the printerless by offering prints of some models on Etsy. A recent order for a set of three Magic: The Gathering +1/+1 counters prompted me to download the new MakerWare to try printing multiple models with a dualstrustion printer.
These are small models and they should print quickly, which makes them ideal test subjects. (These counters are available in The Forge, so go ahead and print some for your local Friday Night Magic game. Tell ’em Zheng sent ya.)
Launching MakerWare shows me a familiar interface, including the NYC skyline that I’ve maligned in the past as an unprofessional distraction to the process of 3D printing. I have it on decent authority that this image is the view from Brooklyn, which makes sense given that MakerBot’s HQ is there.
Back to the review: I reach into my Bag of Holding, withdraw an STL, and MakerWare puts it in the center of the build space, defaulting to white plastic for the build material.
I Command-C/Command-V twice, and now I’ve got three +1/+1 counters. This little feature is far and away my favorite improvement MakerWare makes over grizzled warhorse ReplicatorG. The GUI’s very easy to use when it comes to duplicating and arranging objects on the build platform.
Minor feature request: I’d like to be able to select multiple items and group them the way I can in Illustrator, so that I can click one and rotate/scale/translate the group around a common origin. This functionality is kinda-sorta of implemented with a drag across multiple items, but there’s always a chance you’ll grab something else on the build platform by accident.
I import a new item (the -1/-1 counter) and it shows up at the origin, which I guess is to be expected but I have trouble selecting it because another very similar item is in the same spot. I try to move it out of the way and I end up screwing up my placement and I have to start over.
This time I import a single instance of each counter. There is no snap-to-grid option that I can find, but there is an Auto-Layout feature that easily separates the models and places them independently on the platform. Very nice.
Next. I want to print the -1/-1 in black, and the +1/+1 in red. This is pretty easy to do. Click the instance you want to change and then click the Object button. Select the extruder you want to use. In my case I’ve preloaded the Replicator Dual with black on the right and red on the left.
There’s a color swatch in the Object popup, but clicking on it doesn’t bring up a color picker the way I’d expect it to. Instead I have to go to Preferences, which seems like a weird place to change an object’s settings. I guess if you’re thinking that you’re setting the preferences for the bot it makes sense, but I prefer to think about the object I’m building rather than the tool I’m using.
It’s easy to make the +1/+1 counter red, and now I’ll just copypasta the pair of counters and I’ve got three of each. So far, so good.
I click the make button and get a bunch of well-organized settings, but I’m going to pretend I have no idea what I’m doing and just accept most of the “High Quality” defaults.
I’ve never managed to get a print to work on a Replicator Dual with lower than .18 layer height, but the High Quality settings default to .1 layer height. Either that’s a theoretical minimum that better geeks than me have reached, or it’s a minor oversight in the software. I change the layer height to .2 just to be safe.
My first print fails due to an off-kilter build platform and I have to cancel it from the bot. This isn’t a MakerWare-specific problem– it can and does happen with any software.
Feature request: It’d be nice to have a “try” again button, because now I’m waiting for the slice to finish again. It seems odd to me that MakerWare isn’t caching the most recent slice operation so I can try again quickly. Failed prints aren’t exactly rare as hens’ teeth, and this slice-fail-repeat pattern is really slowing me down.
I re-slice, wait, and try again. This time, it turns out the left extruder head is slightly higher than the right. The first layer of red counter goes to la-la-land, crashes into the emerging black counter, and the whole print goes kablooie. I cancel, get out a wrench, and adjust the hardware while the extruder nozzle is still warm.
This is frustrating, but not unexpected in the world of home 3D printing. So I try to keep things simple, and go back to printing a single color print of a single -1/-1 counter with Make it Now. Success.
I need to print two more of these, so I Make To File and export the gCode. The gCode file is ready in a few seconds.
I choose File->Make It from File (this really should be an option under the Make button) and a dropdown appears. I click Make It and the build fails before it even gets to the printer. It tells me to look at the log to see what happened. I see a bunch of cryptic errors in the logs that I’m unqualified to troubleshoot. I’m abandoning this method for now, and I’ll just print two more single copies of the -1/-1 counter, slice delay and all.
I’ll also need some red +1/+1 counters, so in the interest of keeping it simple I import the STL, change the color of the instance to red, and discover a bug shortly after I hit the Make It button. This version of MakerWare doesn’t like single-extruder prints with the left nozzle for some reason.
The Replicator goes through the motions, tracing an empty line on the build platform, but the extruder’s not heating up. It’s got residual heat from a previous attempt, but it’s not getting hotter.
But. Both extruders work just fine if I try a dualstrusion print again, now that I’ve leveled the HBP and made sure my nozzles are both at the same height. They work just fine in that they manage to extrude plastic, but they do that job just a little too well.
Both prints have these filament morgellons sticking out of them. Close observation during the print reveals that a little bit of filament continues to seep out of the nozzle as the machine switches colors. That tuft of filament catches on the print the next time the extruder sweeps over the top layer. Maybe this could be fixed in gCode by running the extruder drive motors in reverse for a bit in-between colors. I dunno.
This is more cleanup than I want to get into. Probably better to print one color at a time.
At this point my effit-o-meter’s in the red zone, so I give up and go back to printing with ReplicatorG. It looks like MakerWare is sufficently advanced to handle a simple import-and-print operation, but for more complicated operations I’d prefer software that allows for quick and easy print iterations.
