Yesterday, the guys from 3D Printing for Beginners did a Tripodmaker Review of our latest Tripodmaker Black Edition. You should definitely check out what they wrote on their blog post. You can read it here.
We have already received many questions based on their blog post that we wanted to clarify to our readers here.
DOES SHIPPING OF THE PLEXI PANELS OFTEN GO WRONG?
The answer: Not any more
Shipping of the plexi panels has been a pain at the launch a few months ago. Within the regular box, shipping goes terribly wrong. This is why we currently opt to ship the doors separately in a dedicated packaging, separate from the printer.
This package is way lighter and can be handled in a more gentle way, and not with brutal force. As mentioned, our device is rock solid and build to last, this means it is not a box to do a walk in the park with and requires some heavy lifting.
DIMENSIONAL ACCURACY IS IMPROVED
We changed our calibration procedure, creating prints within +/- .15 mm of tolerance. This is something you'll have to take our word for it =)
THE STRINGING AND X-Y-RESONANCE TEST FAILED, BUT WHY?
The answer: The reviewers received a prototype of the machine and there have been several firmware and software updates since then. To get a review out for you as soon as possible, this was the only possible way of working.
At the time of testing, our Prisma software was not up and running. This means slicer settings were not 100% optimized yet when compared to our standard Repetier Host set-up. There the user has a certain freedom to operate regarding temperature and speed settings.
But let's be honest, the guys from "3D printing for beginners" know what they talk about. So how could this go wrong?
Well, stringing is not an easy thing to tackle, and often requires a combination of settings, like acceleration of the retraction, specific movements before hopping, acceleration and jerk for travels between two spots where material should be deposited, and of course the temperature setting.
Same goes for x-y resonance. Rigidity of the frame is one factor, but speed, jerk and acceleration make or break the final results of every printer.
While the temperature is a setting the user can change to fix the stringing, the other parameters like retraction, acceleration and jerk are not included in the printer menu. We have seen that this only leads to confusion or frustration with our customers.
As tests were performed by 3D Printing for Beginners somewhere October - November 2015, our demo device was still fitted with the old firmware set-up.
The acceleration and jerk during printing was set too aggressive, resulting in x-y resonances. Then again, the acceleration of the printer travels was to slow, allowing the filament to ooze and string heavily.
At the moment, printers running software version 0.92.8i should not be suffering from such sever troubles.
