Files to copy on the SD card
1°) Download the corresponding le to your MicroDelta Rework
- Standard MicroDelta Rework (without option), download this le at: Conguration_MicroDelta_Rework.zip
- MicroDelta Rework with heated Bed, download this le: Conguration_MicroDelta_Rework_heatbed.zip
You can also nd these les on our website’s «Support» section», MicroDelta_Rework / Logiciel / Conguration /».
2°) Once downloaded, unzip the le and copy all its content to eMotronic’s SD card.
Windows : what you should have on the SD card aer this step
Objective : copy the conguration les to the eMotronic’s SD card.
Note: SD card is usually detected automatically and its content displayed once you connect your 3D printer to you computer. e
SD card generally appears as drive «E:» or «F:» but it can vary depending on your hardware.
3°) Press the «Reset» button on the 3D printer (located on one side of the lower plate).

PREPARATION
4°) Check in the device manager that the eMotronic is properly recognized.
Take note of the commu-
nication port attributed
to your printer
Port Number
COM5
Windows : Device Manager
With Linux : Command line terminal
Use the following command : lsusb
eMotronic board will show as «OpenMoko, Inc».
make sure that a USB port is attributed to the board using the
following command : ls /dev/tty
Usually, the port assigned to the port is «ttyACM0», «ttyACM1»
«ttyUSB0» or «ttyUSB1».

Connecting your printer to Repetier-Host
1°) Run Repetier-Host soware.
2°) Go to «Cong» then «Printer Settings».
3°) Select the COM port assigned to your MicroDelta Rework.
Select the COM port

4°) Click on Connect.
is one should change color, becomes green when
connected
5°) Check that the extruder’s temperature is consistent (logical value)
and the printer’s status is «Idle» as shown below:
If you have a Heated Bed, its temperature will be displayed
next to the extruder’s

Motion test
1°) Go to the «Manual Control» tab and click on the Home shaped icon
(is should initialize your printer = move all axes to origin). 2°) Make sure that EVERY sliders move up till hitting it’s
corresponding endstop.

PREPARATION
Automated Calibration
1°) Go to «MicroDelta Rework» tab, launch the calibration and
follow the steps.
2°) Mount the calibration module on the printer’s core,
and plug its jack connector on the eMotronic board.
3°) By clicking «Next», the calibration begins and calibration module
will start it’s multi-point bed probing. is process can take several
minutes.
4°) Once the probing is done and the bed plane successfully
corrected , you should set the Z maximum height.
e «MicroDelta Rework» plugin is still not available for Mac
OS users, it will be necessary to perform another calibration
method explained in appendix.

5°) Remove and unplug the calibration module. Place a paper
on the center of the bed.
6°) Follow the instruction on the screen to properly set the
maximum Z height of your 3D printer.
5°) e calibration process is done! You can now print the
last piece of your 3D printer: the Spool Holder.
e calibration process is meant to be done once and not
before every print. In some cases the, calibration could
become unaccurate, aer disassembling and reassembling
structural parts of you printer per example, you should
then calibrate again your printer.

Heating Test
1°) Go to Manual Control tab, click on Extruder heater activation as
shown below:

2°) Check that the target temperature is reached :
If the target temperature is not reached or the actual temperature
varies a lot around the target temperature, perform a PID calculation
(see appendix).

Charging lament
2°) Disengage the extruder
Disengage by pushing
here
3°) Insert the lament in the extruder’s inlet and
push it as far as possible
inlet
4°) If you encounter a hard point while inserting the lament,
engage the extruder and turn the drive wheel until the lament
gets to the nozzle, melted lament should start coming out

1°) Cut the tip of the lament with a certain angle
to make its insertion in the extruder easier
5°) Tighten the spring strongly by turning the knurled screw.
Note: if the thumbwheel is not tight enough, the lament will be badly driven.

PREPARATION
Extrusion test
1°) In the «Manual Control» tab, perform a slow extrusion of 50mm.
50 mm Extrusion
If this is not the case, adjust accordingly the pressure exerted on the lament
from extruder, and this by turning the knurled screw of the extruder.
2°) Verify that melted lament comes out of the nozzle regularly.
