Safety:
Your Acceptance of Responsibility:
There are a number of potential dangers when using the PolyPrinter.
these do not normally present large risks. However, you must accept the responsibility of managing those risks yourself, and in turn so must you also be responsible for, or transfer responsibility to anyone else using or who has access to the machine. Do not use or purchase the Polyprinter without full acceptance of this responsibility.
PolyPrinter Operation
By its nature, the PolyPrinter must use some very hot components.
The heated bed and its supports can be hotter than boiling water. Treat it with as much
caution.
The “hot end” where the plastic is melted is even hotter. It is in the range of a stove
element. It WILL cause burns if contacted while hot.
There are also potential problems of a chemical nature:
Acetone, which is (optionally) used occasionally to clean the bed surface, is flammable
and its vapor may be harmful. It must be used only on a cool bed, and never poured or spilled. The room must have adequate ventilation to disperse the vapors. Acetone on a heated bed will vaporize rapidly, forming an explosive mixture.
The ABS or other plastics used for printing may give off fumes. In general these are not
deemed very toxic but some people may develop a reaction after intense or long term exposure.
Keep small children, the uninitiated, and anyone else not able to be safe, away from the
PolyPrinter when its hood or side panels are open.
Mechanical Dangers:
The moving components of the PolyPrinter can hit, pinch and trap hands and fingers. Sometimes they can move surprisingly quickly, and with enough force to cause harm. Do not interfere with the moving parts. Be especially careful not to have a finger or hand become trapped between the head and the bed, since both can cause burns.
Misuse, abuse:
Do not use the PolyPrinter as a bird cage, reptile habitat, pet dryer, cat-startler or
anything else that could harm your pets. Using it to dry books, warm coffee, make cupcakes, and to dry insects is fine.
Pets can be bothersome. Cats in particular recognize that the PolyPrinter is a

reasonably-empty box. Cats will also think the top of the PolyPrinter was designed to warm their feet and tummies. That’s OK. It has been specifically designed to take the occasional helpful feline’s weight, since, in fact, during development their presence and opinion was not optional.
Part Cleaning
Support removal is generally not too terribly difficult, but does depend entirely on the
part, and the settings used for support. A good pair of small needle-nose pliers with grippy serrations in the jaws can be used to tear away a great percentage of the support, most of the time. Using the pliers can be safer than using a knife.
If using a knife, be sure to cut with the knife pressure in a direction away from body parts
or anything precious - a knife will very often shoot far past the cutting point when the plastic suddenly gives way.
In general, it is best to have a good solid work surface to do parts cleaning upon. Protect
it with a sheet of something durable but not precious, like a cutting board, cardboard, wood or a magazine.
Try to orient the part being cleaned so that you are generally putting downward pressure
on the tool, such that the desk surface takes all the force and is also what is hit by the tool when you cleave the plastic.
Use finger guards or leather gloves to protect against minor nicks and cuts.
Use tools that are just sharp enough to do the job. Sometimes a slightly duller tool will
actually make support removal easier, because it does not dig into the plastic so much.
Computer Requirements
There are three main activities typically involved with using a 3D printer:
Designing parts and preparing the 3D files
Processing the files before printing (“Slicing”)
Sending the files to the printer and printing them.
Each has its own effect on the requirements the computer needs to meet.
It is possible to use a relatively slow, older computer to do all of these things. It generally gets annoying to deal with a very slow computer though, so if you have a choice, and certainly if you have the budget to buy a new one, it is best to aim a higher than the minimum specifications.
Video
A good video card or the newer Intel integrated video will give a nicer experience with most 3D

design software, since it generally involves a need for rapid refreshing of the display. In addition, the software interface to the printer, Pronterface, updates a display of the printing process by default that takes up quite a bit of video performance, and can actually slow down printing and reduce print quality if on a computer with slow video, if not put into a mode (“Mini Mode”) where that drawing is suppressed.
CPU
The slicing programs e.g. Kisslicer will use all available processor cores to speed up the slicing process. An old single-core machine like a Pentium 4, or a Centrino, will be much slower than a multicore chip like an Intel i7, which has eight effective cores. This is not too much of an issue for small parts, and is merely a question of the time you’d have to wait for the slicing process to complete. A generally useful price point is an i5.
RAM
The design programs and especially the slicing programs can use large amounts of memory to hold all of the 3D information when they process the files. Like the number of cores, this can be exchanged for time, but sometimes, and it is again much more of an issue with the larger parts, the amount of time required can rise dramatically, if the computer is bogged down moving information back and forth between hard drive and RAM because there is not enough RAM to work on it all at once. Aim for at least 6 GB if you are looking at a new computer.
Operating System
Windows 10 is preferred but it is possible to use Windows 7, or Windows 8 (requires a few
extra steps during installation). We only recommend considering 64-bit versions.
Apple Mac, Linux: Will work but no install package yet. Each software package must be separately installed.
NOTE: PolyPrinter is no longer formally supporting installations on 32-bit operating systems.
System Specifications
Bare Minimum:
Intel Core Duo, 4 GB RAM, Intel integrated video. Windows 10 64-bit. Effects: Will need to use “Mini Mode” in Pronterface while printing. Kisslicer may issue warnings about RAM, and will be slow to slice files. 64-bit operating system
Useable:
Intel i3 or i5, 6 GB+ RAM. There is a lot of variation in the video performance in this

range, but if the computer is labeled as an “Entertainment” system it may be adequate. Windows 10 64-bit.
Better:
Intel i7, 8+ GB RAM. If new, the video should be fine. Windows 10 64-bit

The mechanical parts that you might normally need to interact with are yellow.
Main Components
X Carriage - travels left and right
Y Carriage (Printer Bed) travels for and aft.
Z Height Adjuster - adjusts nozzle clearance to the bed for the first layer
Front Switches
At the lower left side there are two black switches. The top one controls the “Camera” light on the right side of the hood. (If equipped.) It’s good for general lighting of the printing area, and especially helpful in giving the camera enough light to work with, especially if you want to monitor printing progress remotely in a room where the lights have been turned off.
The lower switch controls a light on the X Carriage to better be able to see printing in progress.
On the side of the same switch housing is a red Reset switch. This will interrupt any operations in progress, cancel printing and disconnect communications. It is not normally needed or used as part of operations. It is occasionally needed if USB connections have been disturbed.

You do not need to turn the PolyPrinter off when it is not being used. Leaving it
on takes very little power, and maintains the USB connection so that it is able to
print on demand.

Camera (if equipped)

The built-in camera (PolyPrinter Plus) provides the opportunity to use a program on the connected computer to monitor printing. There are several methods for doing this:
Create a Skype or other internet communication account just for the printer. Set it to
auto-answer calls, and you can the n call your printer from another computer or a smartphone. This is only suitable for situations when it is acceptable for the monitoring to be done by only one person at a time. It may also create privacy problems if the camera (which has audio too) allows someone to eavesdrop on the general area of the printer, unbeknownst to others.
Set up a frame-capture program that periodically uploads an image from the camera to a
web server. This is good for when the printer is shared such that a number of people are interested in the status. An example can be found at http://www.yawcam.com/
Adjustments
Z Height
This adjustment is very important to successful prints. It sets the thickness of the first printed layer. It needs to be in a fairly narrow range of height for that first layer to stick properly. Once you have it set correctly it usually stays the same for quite a while, until something changes. The PolyPrinter ships out only after it has been adjusted properly and has successfully printed a number of objects. However, it may have had a rough trip to your door, and may need a bit of a tune-up before you can print successfully.
How to tell if it’s correct:
If you think it is close, but want to be sure, try to print a part, with a setting that includes a “skirt” (see Kisslicer), which is a line of plastic laid down around the outside of the part before the actual part and its support. The skirt should be a bit “fat” - quite a bit wider than it is tall, and be well-stuck to the bed. It should also be the same width all the way around, except near where it began, because the plastic doesn’t flow at full rate until a few inches of skirt have been laid down. You’ll get used to spotting whether the skirt looks right, after you have been using the printer a while.

Procedure:
It is important to have the X Carriage all the way toward the left (the home position) when setting the Z adjustment, because there it is more independent of the Z Tilt (see next section).
1. Make sure the head has no plastic attached to the bottom face of the nozzle (use
2. Clean any plastic from the bed, especially at the home position.
3. Use Pronterface to:

the Brass Brush included in the Tool Kit).
a. Home the X axis. Press the button on the top left of the movement
command circles.
b. Turn off the motors. (If the printer has recently printed or moved its head
they will remain “on” for about a minute.) Press the “Motors Off” button which is along the left side.
The head should approach the bed, and may touch it.
5. The ideal height after Z Homing is zero clearance between the bottom surface of the nozzle and the bed.
6. With a little practice you can see a gap if there is one. Take a look at the clearance, if any, between the bottom face of the nozzle and the bed. Raise the nozzle slightly, using the “Z + .1” buttton in Pronterface, if necessary, to get a visible gap. Then slide the X Carriage toward the right, and see if the clearance remains roughly the same. If it is noticeably different toward the right, you should first follow the procedures below, in the “Z Tilt Left-Right” section.
7. Take an ordinary piece of photocopy paper, and slide it under the nozzle, with the X Carriage all the way to the left. Do a Z-Home. The nozzle should grip the paper firmly.
8. Raise the nozzle .1 mm. The paper should still be just a bit gripped.
9. Raise the nozzle another .1mm and the paper should be completely free.
10. If that is not the case, see “Adjustment”, next.
9
Adjustment:
The Z Height adjuster is the yellow knob on the left X Carriage, hiding behind the left aluminum vertical support. (It’s a little shy and does not like people watching it change.)
If the head does not even grip the piece of paper at all, or completely lets go when raised .1 mm, turn the knob counter-clockwise to reduce the clearance.
If the paper is still gripped after raising a total of .2 mm, then increase the gap by raising the head, by turning the Z adjuster clockwise a little.
One full turn is .5 mm, which is quite a lot. If it’s already very close, turn it much less than a turn - 1/8th or ¼ turn at a time is a good starting point. Each time you turn it, again press the Z Home button, to let the printer find the new home position and let you see what difference the changed setting made.
How to tell if the head is being pressed too hard into the bed:
If the head is adjusted too low, you may get warning messages during printing, or just before it begins to print. If you are doing the “piece of paper” test described above, the paper will still be gripped a bit or a lot even after raising the nozzle .2 mm or more.
1. Move the X carriage or the Y carriage by hand (Motors Off) and see if the head leaves marks on the bed tape. It’s generally well-adjusted if it just barely makes marks. If it’s tearing up the tape or digging into it at all, it’s definitely adjusted too low. Turn the knob clockwise to increase the clearance height, pressing Z Home with each change, and see whether it stops rubbing the bed so much.
2. Once you get it to where it seems close to correct, check the Z Tilt (below).
Z Tilt Left-Right
Your PolyPrinter should not require much attention to the left-right height adjustment. But if you think it has drifted off, or the whole X carriage assembly has been lifted off and the nuts disturbed, perform the checking procedure above, up to the point of “Adjustment:”.
Since the Z Height detector switch is on the left side, we adjust the right-hand motor to match the left.
Press the “X Home” button on Pronterface. The X Carriage should go all the way to the left.
Press the “Z Home” button. The nozzle should approach and just barely touch the bed. It is OK if it has a small gap, for this procedure - in fact, it makes this a little easier to
10
perform, so if there is no gap at all, create a very small one now, by pressing the “+Z .1” button in the top half of the vertical set of buttons to the right of the main circular controls in Pronterface. Press it one or more times, enough to get a small visible gap between the nozzle and the bed. It doesn’t much matter what the size of the gap is, as long as it’s small enough for you to see whether it changes significantly, in the next steps.
Press the "Motors Off" button on the left upper side of Pronterface. Also make sure that the Heater and “Off” button is pressed so you don’t get burned while doing this procedure.
Then move the head to right manually and see whether the bottom of the nozzle moves away from or toward the bed as you move to the right.
Perform the same “piece of paper” test on the right and left sides. What matters first of all is that it grip it the same left and right, Use the “.01 mm “ to find a good height for this test. It doesn’t matter whether it’s correct overall, yet, as long as it’s the same left and right.
When the clearance is the same left and right, go back and perform the overall height adjustment described above in “Adjustment”.
You will need to loosen the two setscrews that couple the right hand Z rod to the belt drive assembly at the top of the printer. They are a bit hard to see. They are opposite each other, so if one is easy to see, the other will be harder to see. Use the 1.5mm (smallest) sized hex driver tool.
Once you do that, you can make fine adjustments by slightly rotating the Z rods (most easily done down at the motor shaft). Hold the left threaded rod so that it doesn’t turn, and turn the right side one.
Twist the right-hand threaded rod counter-clockwise to decrease clearance
Twist the right-hand threaded rod counter-clockwise to increase clearance
You should feel little “steps”. Generally, you should only need a handful of steps. That is only a few degrees of rotation. Do a few, test, and decide if it’s enough or too much. Take your time.
After you have made any adjustments, slide the head back and forth to check how the clearance changes. If you can’t see it change, your alignment is good.
Tighten the two setscrews.
Rarely Needed Adjustments:
X Belt Tension
Y Belt Tension
Each tension adjustment is an easy turn of the respective screw adjuster. Righty-tighty.
The belts should certainly have no slack at all, and should have enough tension to make a
