I-B Table / Bed

* 2016-04-07

Overview

› BigRep ONE comes with a heated (aluminum) printing bed, incl. polyamide

printing tape which can be replaced.

› The heated bed and polyimide tape ensures that the first layers stick to the

bed.

› The attachment of the bed is directly mounted to the frame.

› The bed is heated by two heating mats, glued to the rear side of the table.

› The bed is float mounted to assure expansion while heated.

› The height of the bed can be adjusted – but this is only necessary once

during the setup and should not be done by the customer.

› The adjustment of the bed is important to ensure correct leveling proce-

dure.

› The bed can be heated up to 85°, 60° is regular printing temperature.

I-C End stops

* 2016-04-07

Overview

End stops are the datum of each axes and make sure that the printer knows where
it is.

In general you need at least 3 end stops, 1 for each axis to define the homing
position.

BigRep end stops (see figure next page)

BigRep ONE comes with 6 optical end stops, two for each axis. The three addi­tional end stops make sure that the printer always knows the maximum position
of each axis, even when the operator used the wrong build volume during slicing.

X- and Y-end stops are both fixed and not allowed to change.

The height of the Z

min

end stop has to be adjusted during the setup to define the

correct ratio between end stop and height of the printbed.

→ To adjust the correct height for Z

min

end stop please have a look at → V-H Lev-

I-D Portal

* 2016-04-07

Overview

BigRep has three moving Axis, X, Y and Z. If you are standing in front of the printer
the movement of the axis is as following:

› X-Axis: moves the extruder in X direction from le to right.

› Y-Axis: moves the X-Axis Y direction from front to back

› Z-Axis: moves the X-Axis and Y-Axis (portal) up and down

Mechanical Description

X-Axis and Y-Axis are driven by one stepper motor (Nanotec) each + belt and pul­ley.

Z-Axis is driven by one stepper motor (Nanotech) + belt and several pulleys

Maintenance

Please have a look at section V - Maintence of the technical manual for further in­formations.

All motors and pulleys can be replaced if needed.

X- and Y-Axis are using self-lubricated carriages and have to be lubricated with
industrial grease about once a year. We recommend mineral oil-based lubricants.

All belts have to be lubricated with silicon spray about once a year.

It is important to check the tension of the belts, which should be around 20Hz.

Note

As Silicon and Grease react with each other, please make sure that you never put
silicon spray at the X- or Y-Axis.

I-E Extruder

* 2016-04-07

Overview

The extruders are the main unit for 3D printing with the BigRep ONE. The extruder
contains the hot end (n) where the filament is heated and then squeezed through
the nozzle (o).

The BigRep ONE is equipped with two extruders which can be changed individ­ually. Given the two extruders, the two nozzles can be used simultaneously for
separate printing projects (with the same or diering diameters), e.g. to print ad­ditional support material for supporting structures alongside the main object.

If you want to use other nozzle diameters than the ones installed, the extruders
need to be retrofitted. You can either replace the entire extruder or only the hot
end. In both cases the extruder must first be removed from the machine.

Auto Leveling

BigRep ONE comes with an auto leveling X-Axis to Bed

The laser sensor is mounted to the X-Axis le from the extruder

The sensor measures the distance between X-Axis and Bed

Before you start a print, the sensor measures (with 3 points) the distance be­tween Axis and Bed + automatically levels correct z-height during a print in case
the planarity is not 100% correct in total

The laser cannot balance minimums and maximums within the bed.

* 2016-04-20

Control Unit is preassembled, directly connected at the back of the printer.

To open the control unit the operator has to use the key (delivered with the ma­chine) + has to turn the main switch to the le position (next to “o”)

The control unit has to be closed at any time during the machine is running. Cus­tomers are never allowed to open the control unit.

Due to security reasons the machine cannot be switched on when the control
unit is open.

In case maintenance is needed, BigRep Service Sta is allowed to open the con­trol unit and switch the machine on. In order to do so you have to tape the securi­ty switch at the top of the control unit.

UPS onboard

UPS ensures that the PC will have power for a short time in case of a current pow­er interruption.

Due to security reasons the fuse of the UPS is plugged out during transportation
and has to be plugged in before the setup.

There is one spare fuse delivered with every printer.

Important
Aer the machine is switched o, the operator has to wait 30s before it is al­lowed to switch on the machine again. Otherwise the PC wont start.

› Smoothie is a free, open-source, high performance and modular G-code

interpreter and CNC control system for the Smoothieboard 32bits control­ler. [http://smoothieware.org/]

› Smoothie is a firmware. That is a program that executes on a micro-control-

ler, basically a very simple/small computer used for very specific tasks. The
micro-controller is located on a controller board, for example Smoothie­board (BigRep: Boogieboard), where it executes the Smoothie firmware.

› This program receives instructions from your computer ( typically G-code,

generated by CAM soware), and executes them, for example by moving
stepper motors in a coordinated fashion, and operating tools.

› Firmware is written by BigRep and based on the open source smoothie

project, like many other FDM 3D Printer and/or CNC milling machines.

› Firmware updates will be pushed automatically to the printer by BigRep if

connected to the Internet.

V-E Check stepper value axis

* 2016-05-07

In case there is an issue with correct measurements of the prints, the stepper
values of each motor have to be checked. The stepper values tell the printer how
many steps per mm have to be done for each axis. Example for X-Axis.

1. Home

2. Drive to G1 X200 Y200

3. Use laser as 0 position

4. Drive to G1 X500 F3000

5. Measure the distance with metering rule (use laser)

6. In case it is more or less than 500mm, for example 490mm:
500/490 = 1,02 --▷ multiply 1,02 with the present config value and change
the value within the config + save config

Check stepper value feeding wheel

Beneath the axis the stepper value for extruder feeding wheel is most important,
as this value has to be changed aer hardware replacement and/or change of
material:

1. Mark 300mm of filament (from top of extruder)

2. Extrude 300mm of filament

3. Measure the filament which is extruded

4. In case it is more or less than 300mm, for example 260mm:
300/260 = 1,15 --▷ multiply 1,15 with the present config value and change the
value within the config + save config

V-F Lubricate

* 2016-04-07

Axis

Regularly clean and lubricate the X-guide rail (H), Y-guide rail (F), Z-lead spindles
(C), and Z-guide shas (B).

Please only use approved industrial lubricants. We recommend mineral oil-based
lubricants for rolling or plain bearings.

Regularly check the lubrication of individual components. Ensure that they are
always covered by a thin lubricating film.

Belts

Lubricate X, Y and Z belt with silicon spray.

To lubricate the Z-Belt, you have to open the cover at the top of the machine in
each edge.

To lubricate X and Y belts you have to open the cover of the axis.

V-F 1/1

V. Maintenance BigRep

V-G Belts

* 2016-04-07

Maintenance

All belts have to have a certain tension, measured in Hz. In order to measure the
tension you have to open the covers of the axis, manually hit the belt like a guitar
and measure the tension with a trumeter. The tension of X and Y Axis should be
around 15-18 Hz.

You can lower or increase the tension of the belts by using the screws at the
brackets which holds the belts to the axis.

Replacement

Belts can easily be replaced.

You have to open the cover of the axis, loosen the screws at the brackets (4 in
total), take away the old belt and guide the new belt through the pulley.

VI-C Maintenance Config Overview

* 2016-04-20

Only for One.3b: Config/Stepper changes

Changing the Stepper Value

Since the transmission of the new system is 3.33 compared to the old one, the
new value for beta_steps_per_mm would be 53.3 x 3.3 = 177.7. However, high
values seem to influence the firmware, so the number of microsteps for the step­per motors is changed, too. The microsteps were 32 and are now 32 / 4 = 8, so the
new value is 177.7 / 4 = 44.4.

Old New

beta_steps_per_mm 53.33 44.44

This results in changed dipswitch positions at the stepper driver of the Y-axis. It is
found in the cabinet to the le. Check the labels.

Changing the hysteresis of the heater control for the bed

The controller for the temperature of the bed is controlled with a bang-bang-lo­gic, which means turning o at max value and turning back on a min value. This
range is set in the config file, the old value is 1 °C. This means that the heater will
turn o at 1 °C above the setpoint ant turn on again at 1 °C below the setpoint. For
a smoother temperature control, the value is changed from 1 to 0.1.

VI-D Getting Started Simplify3D

Slicing (creating G-Code) is a fully automatic process
– BUT settings used are crucial.

We do recommend and provide you with needed
presetting's for simplify3d. How to prepare:

1. Hardware: Make sure you have at least 8 GB ram

2. Install Simplify3D from simplify3d.com

3. Buy a Simplify3D license

4. Download the BigRep factory file from your
customer portal

5. Double click the BigRep factory file - presetting's
will be loaded automatically

Intro

NOTE: This is a quick start guide, especially made for using simplify3d with your BigRep. You will find the most
important settings and descriptions to get started. For in depth knowledge about the software and each single setting,
we recommend to visit www.simplify3d.com/support.

Overview

VI-E 1/7

VI. Appendix BigRep

Slicing – model settings + place surface on bed

Most important:

• Avoid support

• Use correct size/measurements

• Place the model directly to the bed

In detail:

• Import Model: click at File / Import Model and
load a new .stl file

• Rotate: click at the model (1.), rotate in X,Y or
Z direction (2.)

• Scale: choose percentage or millimeter,
uniform scaling recommended (2.)

• Last step: click at Center and Arrange (3.)

before

after

Slicing – most important settings

To choose the settings for your print, open the
process and go to advanced settings, most
important categories are:

• Extruder

• Layer

• Additions

• Infill

• Support

N

ote: Find a detailed description for each

categories at the following pages.

VI-E 2/7

VI. Appendix BigRep

Slicing – most important settings: Extruder

Most important:

• Choose the correct extruder (T0, T1)

• Choose the correct nozzle diameter you have

installed at the machine (.5 or 1mm)

In detail:

• Extrusion Multiplier = Flowrate, choose 1 as
standard

• Extrusion Width = Single Outline Width, 10-20%
more than nozzle diameter is recommended,
but not a must

• Ooze Control = avoid overflow during z-moves,
standard values are recommended

Slicing – most important settings: Layer

Most important:

• Layer Height (resolution)  choose

between .6 and 1mm with 1mm nozzle &
between .2 and .5mm with 0.5mm nozzle

In detail:

• Top Solid Layers = number of solid layers at

the top of your sample. Choose at least 2.
Increase if you use little infill.

• Bottom Solid Layers = number of solid layers

at the bottom. 3 are recommended and
most often sufficient

• Outline/Perimeter Shells = number of loops

at the “walls”. Choose the correct amount to
avoid gaps or little infill structure.

• Start Points = the “seam” for z-moves.

Choose start point to for example “hide” the
seam in the back

VI-E 3/7

VI. Appendix BigRep

Slicing – most important settings: Additions

Most important:

• Always choose at least a skirt with one outline
to avoid imperfections within the first line of
your print

In detail:

• Skirt = One outline with offset

• Brim = Skirt with no offset and several lines.

Choose Brim to avoid warping and to ensure
that the print sticks to the bed more solid.

• Raft = Brim with layers also underneath the
print object.

Slicing – most important settings: Infill

Most important:

• Choose at least 10% infill, more than 30% are

most often not necessary

In detail:

• Internal Fill Pattern = determines the infill

geometries. Recommended geometries are
Grid (fast) and Honeycomb (solid)

• Interior Fill Percentage = determines the interior

solidity

VI-E 4/7

VI. Appendix BigRep

Slicing – most important settings: Support

Most important:

• Activate / Deactivate Support

• Choose Extruder – whether you want to use

same material or special support material.

In detail:

• Support Infill Percentage = how solid your
support will be. 20% is most often a sufficient
value.

• Dense Support Layers = interface between
support and model. Should be at least 2.

• Support Pillar Resolution = determines the
resolution of each support pillar. 1.5mm is
recommended for small parts. Up to 5mm for
big prints.

Preview and Transfer G-Code

Most important:

• Click at Prepare to Print to slice your model and to

enter the preview mode

• Inspect different layers and feature types

• Change settings and slice again if necessary

• Get build time and amount of material (note:

these values are appr.)

• Save your G-Code to Disk (USB-Stick)

In detail:

• Show in preview = determine the preview mode.

Recommended: Build table, Toolhead, Retractions
& Coloring Feature Type

• Preview By = use the slider next to End, to inspect

layer by layer

• Save Factory File = Click at File-Save Factory File

to save

VI-E 5/7

VI. Appendix BigRep

Advanced

Advanced – Customized Support

before

after

Most important:

• Check automatic support

• Remove/add single structures

In detail:

• Activate = click at Tools/Custimze Support
Structure

• Support Pillar Resolution = determines the
resolution of each support pillar. 1.5mm is
recommended for small parts. Up to 5mm for
big prints.

• Generate Automatic Support = Generates
supports structure similar to the regular slicing

• Remove existing supports = remove single
support pillars

 To use your customized support structures,
just click at Done and start slicing

Advanced – Using Multiple Processes

Process 1 – 15% infill & 0.8mm layer Process 2 – 40% infill & 0.6mm layer

Most important:

• You can create as many different processes
(settings) in z-direction or layers as you like to

• Use different extruders (materials or colours)
for different layers within one print

• Especially for different infill settings very useful

In detail:

• Add = create a new process. Settings will be
duplicated

• Layer Modification = click at Advanced within
your process settings. Determine the start- and
stop height of the selected process

• Prepare to Print = Make sure to Select All
processes after you clicked at prepare to print
