New to 3D printing, my experience has been DISMAY to say the least. Bought the PowerSpec Ultra 3D from MicroCenter. Upon advice from their salesman I also bought the Simplify3D software. After 50 straight hours of work my dismal results are: The FAILURE rate using the slicer included with the PowerSpec is 85% or better. First layers (PLA) almost never stick.

It doesn’t matter if I run 200C tip and 60C bed, or 235C tip and 105C bed. No modification to the build plate surface (BuildTak, tape, glue, spray, etc.) shows improvement. The parts I was able to make have a super simple base geometry. The only mode it will print in is “Standard Definition”. It absolutely won’t print in high resolution, ever. I have leveled the bed repeatedly and between every attempt (a simple symptom to eliminate). Here’s some additional observations: - First layer hardly ever sticks.

- Display will change to Chinese language after power cycle. - Frequent USB connectivity issues, requires power cycle of machine and computer. - Filament guide tubes become dislodged from head from print movement. - Sparse instructions in the box, extra hardware and cables (the heck is the extra cable for?!) - Metal handle not true and warps plastic door when screws tightened (loosen screws and touch with superglue to hold in place). The FAILURE rate using Simplify3D is 100%. I have yet to achieve one print on this platform with over 50 attempts.

The g-code generated slams and chatters my servos ignoring the stop limits. The z-axis build plate is literally inches from the nozzle and it prints in thin air. I have tried every single setup change and tweek that is available; short of re-writing the code. Everything looks correct in the GUI, but the actual print process is a heart breaking joke. The entire experience is anger producing. Up until 3am every night since I bought this setup, I have yet to see a reliable result.

There are actually several more bugs, mini fails, part flaws, etc. Then I am writing about in this post.

I have read every form, post, suggestion available. It appears that many people are printing successfully with S3D and with the PowerSpec (a FlashForge knockoff). In general many people are printing in 3D successfully. I am not one of them. I have 15 total days to return this equipment to MicroCenter, after day three I am pretty much ready to do that. I doubt I will be able to return S3D; the customer service is known to suck or be non-existent.

End rant, thanks for reading. I appreciate the feedback on this post. Very positive and supportive. 3D printing feels more like a community with this interaction. So I took some aggressive steps today. Went down to MicroCenter Denver, spoke with the rep.

He and another customer standing with us admitted that they have had total brain damage printing PLA on this specific printer (PowerSpec Ultra 3D). They both admitted to deferring to ABS when at all possible. Besides the thermal contraction issues (somewhat controllable) they have had success sticking the first layer(s). They also concurred with your statements (spray, glue, etc).

I was really hitting the reliability subject hard with them. I know this is new and emerging (adolescent) technology but from a “sigma” approach to results, I can not ignore the fails and work arounds that myself, and everyone else is experiencing. I returned the PowerSpec Ultra 3D. I purchased the Lulzbot Taz 5. I got it all back home and after a careful setup and calibration proceedure, as well as downloading the Cura platform, I have printed one sample part. The results are amazing and drastically different than the previous.

The Cura is a hearty and effective slicer. Everyone is totally correct about that. The Simplify3D has a few more bells and whistles but guess what; I’m not printing bells! I R&D one off prototypes for the R/C industry.

I need parts that print and work properly within acceptable tolerance(s). I have to say as well, that the Lulzbot is an amazing machine as well (so far).

It is noticeably higher quality and robust. The build volume of the Taz 5 is formidable.

The Cura suite works seamlessly with the machine and I am exactly where I expected to be 60 hours ago. Thanks again for all the info and general support. I remember when digital cameras first came to market (I am 38 yrs old.). Look at that technology now. Let’s keep printing and pioneering. I can’t wait to see what is the future of this industry. Cheers to all.
