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.

Calibration process using command lines

If for one reason or another, you can’t or don’t want to use the «MicroDelta Rework» plugin to calibrate your 3D printer, you can perform this operation using
Gcode commands, here’s how to do this:

1°) Make sure the printhead is at room temperature.

2°) Mount the calibration module on the printer’s core and plug the jack
connector on the eMotronic board

4°) Start the calibration using G32 command, it wil probe 3 points of the
bed.

G32

3°) Go to «manual control» tab. Home or initialize your printer using the
G28 command.

5°) Start the full bed calibration using G31 command, this will probe multiple points of the bed to optimize the rst
calibration. is is known as grid compensation strategy.

G31

6°) Once done, save the grid values using M374 command.

7°) Remove and unplug the calibration module.

9°) Place a paper on the bed

10°) Activate printhead heating and wait to reach 70°C.

11°) Move the printhead down with the arrow keys as shown below in the
manual control tab.
Once the printhead is close enough from the paper move the printhead down
slowly by jogging down of 0,1mm at a time, repeat until the printhead touches
the paper and holds it from moving.

12°) Set the maximum Z height using the M306 Z0 command

13°) Save using M500

PID calculation

By GCODE commands :

1°) Make sure the print head temperature is at room temperature.

2°) Disable the secondary fans.

3°) In the «Manual control» tab, use the input  eld for sending GCODE commands :

Send the following command : M303 E0 S250 C8

Details :

• E0 = extruder number 1

• S250 = target temperature at 250°C

• C8 = 8 cycles of regulations around the target temperature

Once the command is sent, Repetier-Host logs will show you the progress of the calculation.
When the calculation is  nished, the new values P, I and D are indicated in the logs.

4°) Send the following GCODE command to save : M500

If you have the LCD screen :

In the menu of the screen is integrated an option to directly calculate the PID.

Just go to the «Calibrate / PID hotend» menu.

Preamble :  e PID values are necessary for the temperature control of the heating elements. If you  nd that the target temperature is
diffi cult to reach or the actual temperature varies a lot around the target temperature, it may be useful to recalculate the PID values.

Maintenance

A monthly maintenance of the 3D printer is recommended.

Below are some recommendations:

Using a brush, dedust the following:

• Emotronic board

• All the fans to ensure a good airow

• Cold part of the printhead

- To clean the printhead follow the guide dedicated to the Hexagon hotend on the following link:

http://data.emotion-tech.com/highlights_fr/Hexagon%20-%20Notice%20montage-debouchage.pdf

- Clean the teeth of the drive wheel using a sharp ended tool like a needle tip, the end of tweezers or a cutter blade.

- Check & tighten the screws of the 3D printer.

- Lubricate the various mechanical transmission elements with multipurpose grease.

Recommandations

Turning o󰀨 your 3D printer :

After printing, if you want to turn o󰀨 the machine, wait until the print head cools down to room temperature to

ensure that the print head doesnt get clugged.

Transport :

If the printer has to be transported by car or another mean of transport in which it could be subject to vibration, it is
recommended to unplug all the motors from the eMotronic board to avoid damaging it.

Troubleshooting :

A FAQ on the MicroDelta Rework is available on our website in the «Support» section, please refer to it
to troubleshoot your printer, most problems could be solved through this tool !
