If you want to use a different tool for your router or replace a tool, there are a few things you need to bear in mind.

    Before installing the new tool, completely loosen the union nut of the chuck once. Clean the chuck and the motor shaft. Degrease the chuck and the tool with acetone before installation.
    If the chuck is dirty, the tool may come loose. This can result in damage to the milling table.
  • After changing the tool, you must reset the zero point of the milling machine in the GP Manager. How you set the zero point depends on the type of milling machine you have. You can refer to Youtube For most milling machines, watch a video explaining how to set the zero point.
  • In rare cases, you may want to use a tool with a different diameter. In this case, you must enter the diameter in the INI file for your milling cutter under ".\GpSystem\Fraese", the folder is a subfolder of the GP Manager (How to find your GP Manager installation).
  • You must then recreate any existing milling files. The milling files still contain the old values for diameter and zero point. If you use these, the insert will not be milled correctly.
  • When buying a tool, you should pay attention to the direction of rotation of the tool. If you purchase tools from us, you will always get the correct direction of rotation.

If this has not helped, you are welcome to contact GeBioM Support.

With MultiShore materials, there is often a desire to align the insoles not to the rear edge (outer edge of the material), which is standard with block materials, but to a transition line between the materials. GP InsoleFraese offers the option of defining such materials.

This allows insoles of different sizes to be aligned at the transition line. This ensures that the desired material is always in the forefoot.

To do this, the material must be measured and a new placement must be specified in the INI of the milling machine (e.g. GPM_320.ini):

T_Name = MS-BlackOrange // Can be freely named
T_Orientation = HOCHKANT // Alignment of the inlays on the table
T_Stop = LEFT BOTTOM // The material is created here
B_Use_Multi_Auftrag = yes // MultiAuftrag (yes/no)
I_Anzahl_Boxen = 0 // For small blocks it makes sense to define several boxes
B_MultiShore = yes // Use Multi-Shore
I3_MultiShore_Dimension = 345 285 30                              // Fixed size of the material Length x width x height
I2_MultiShore_Transition = 185/245                     // Change material FROM / TO (from material rear)
I_MultiShore_Nullline = 200                                       // Zero line for positioning the inserts
I_MultiShore_Nulllinie_Prozent = 100 // % specification of the rearfoot (from the heel) with which the insole is positioned
T_Arrange = COLUMN // Determine whether the LINE or the COLUMN is filled first

You design an inlay and reduce the material thickness very much because you want to have a thin/flat inlay.
After milling, however, you now realise that the insert is larger than the insert you designed.

Cause of the problem:

The milling head cuts out a rim around the insert. This edge is as wide as the circumference of the milling head.
In the following pictures you can see the same inlay milled twice. Once with a material thickness of 1mm (start and end of the insert are marked with a blue line) and once with a material thickness of 10mm. The difference becomes clear here

Problem solution:

Do not cut out the inlay directly on the edge of the milling block, but on the inside of the milling head.

Control option:

Design the inlay once with a higher material thickness and mill out this inlay once as a test. If the inlay fits this time, then you have simply cut out the inlay a little too generously.

If a single-pass milling machine suddenly stops during the milling process, there can be various reasons for this. Often, however, it is simply because the axis motors have to use too much energy to move the axes. This can be caused by a lack of lubrication, but also by a blunt milling cutter or a feed rate that is set too high. As the machine's control system has a current limiter for the axis motors, it issues an error message if the set value is exceeded.
If the milling process runs without milling material, this indicates one of the above-mentioned causes or a combination of these.
Therefore, check regularly whether the milling cutter is still sharp, the axes have sufficient lubrication and the feed rate is adapted to the hardness of the milling material.
To further reduce friction when driving the axles, it can help to rub a little oil into the sealing lips in which the axles are guided. The use of WD40 is not recommended, as this agent can penetrate into areas where it has a counterproductive effect due to its strong creeping properties and can cause faults that are difficult to locate.

Causes of errors

The error occurs if the UEFI option is activated in the BIOS. In this case, in some cases the EFI shell is called up during PC startup.


Start the BIOS while the PC is booting.

  1. Switch on the computer of the milling machine.
  2. For most milling machines, you must press the "Unf" key. This is located on the keyboard to the right of the Enter/Down key.
  3. This takes you to the BIOS of the milling computer.
  4. Select "Boat options
  5. There should be an option "UEFI". Change this value to "Normal„.
  6. Save the changes and restart the computer.

The error should no longer occur. If the error still occurs, please contact GeBioM mbH Support.

Error description

The GP Manager still displays the current milling jobs. However, it then crashes immediately.

Causes of errors

The GP Manager does not automatically delete old milling jobs. If there are too many completed jobs, the GP Manager can no longer create the list of completed milling jobs and crashes.


Rename the directory with the completed milling jobs and create a new directory.

You can find the standard directory as follows:

  1. Make a Right click on the GP Manager link and select "Open file path
  2. Open the folder .\GpData\Fraese\Inlays
  3. Name the folder Done um.
  4. Create a new folder with the name Done

In future, select the "Completed orders" and delete orders that are no longer required.

  • GP M101
  • GP M102
  • GP M103
  • GP M151
  • GP M302
  • GP M303
  • GP M251
  • GP M202

Under "View" -> "Status of the machine" boxes at the top right are highlighted in light red. This means that the limit switch has been triggered for this axis. In the example illustration, the negative limit switch of the X-axis has been triggered.


Causes of errors

The router is in the limit switch position. This can happen if errors occur during milling.


The tiller must first be moved out of the limit switch position. This can be done in several ways.

  1. Start CNC Remote

Identify milling type with the GP Manager

The easiest way to recognise the type of tiller is in the GP Manager. To do this, proceed as follows.

  1. Start the GP Manager.
  2. Select "Analysis" -> "GP milling machine„.GP-Manager-Analyse-Fräse-klein-markiert
  3. You can read the type of milling machine you are using in the GP milling machine module.


Identify milling type by appearance

There are several router series, which differ at first glance in the colour of the housing.

turquoise: 100 series milling machines (GP M101, GP M102, GP M103)
blue: 200 and 400 series milling machines (GP M201, GP M202, as well as GP M401 and GP M401xxl)
grey: 300 series milling machines (GP M301, GP M302, GP M303)
red: milling machines of the 50 series (GP M151, GP M251)

100 series

All 100 series milling machines have a turquoise-coloured housing and are connected to an external computer via the COM port.

GP M101
These milling machines have a motor from Kress or Suna, the carbon brushes of these motors must be cleaned regularly. The computer is not integrated into the router and is connected with a COM cable.

GP M102/GP M103
Both milling machines have ISA750 motors, which are maintenance-free. The computer is integrated into the router. The GP M103 can be distinguished by the fact that it has two USB sockets and a switch at the bottom left (see picture below).



200 series

All milling machines in the 200 series have a blue housing.

GP M201

300 series

All 300 series milling machines have a grey housing. All milling machines are controlled via a COM port.

Fräse gross

GP M301
The GP M301 is controlled using the GP Remote programme and connected to an external computer via a COM cable.

GP M302/GP M303
On both types of milling machine, the type plate is located at the bottom left of the milling machine (see picture below). The computer is integrated into the milling machine.



400 series

All 400 series routers have a blue housing. The difference between the GP M401 and the GP M401xxl is the size of the milling table.

GP M401
The milling table of the GP M401 is 1205 mm long.

GP M401xxl
The milling table of the GP M401xxl is 1600 mm long.

50 series

All 50 series routers have a red housing and the computer is integrated into the router. The easiest way to distinguish between the two routers is by the arrangement of the buttons on the front.

Error description

Instead of the new job, the milling machine mills the old job again and again. The milling machine does not accept new jobs.

Causes of errors

This is usually due to a network problem or an operating error in the GP Manager. Make sure that you have selected "Analysis" -> "GP milling machine" after you have selected the milling job also "Create milling file" select.


  1. Start the GP Manager
  2. Select the customer for whom you would like to create a milling order via "Project" -> "Determine", or create a new customer.
  3. Select the GP CAD file that you want to use for the milling machine by double-clicking on it.
  4. In the new view, select "Milling

  5. You can set the settings for the milling job in the following dialogue. Click OK to write the milling file to the output folder.

  6. Select "Analysis" -> "GP milling machine" the new order should be displayed here.
  7. Select the order by double-clicking on the date.
  8. Select "Create milling fileGP-Fräse-Projekt gewählt-markiert
  9. The file should now have been transferred to the milling machine. The job is now only orange, the buttons at the bottom right are no longer activated.Fräsdatei-erstellt-markiert
  10. To be on the safe side, manually check whether the GP Manager has also transferred the milling file to the milling machine.
  11. The paths at the top right under "Analysis" -> "GP milling machine" enter the folders for the Milling orders and the Milling files to.
    GP-Fräse-Projekt gewählt-ordner-markiert
  12. Start CNC Remote and select "File" -> "Open" to check whether the path here matches the folder for the milling files. If the path is not identical, it is often the case that the GP milling machine writes the milling file to a temp folder. In this case, there is a network error.
  13. Make sure that the detailed view is activated in the following dialogue.
  14. Check whether the modification date corresponds to the time at which you created the milling file.
  15. Check whether the folder matches the folder configured in the GP tiller.

Error description

The brush on the router is so worn that it can no longer generate a sufficient vacuum and you want to change the brush yourself.

You need:

  • 1 x 4 mm or 5 mm HSS drill bit
  • 1 x replacement brush
  • Pop rivets (4 mm) as well as matching washers and riveting pliers
    • We strongly recommend riveting the new brush as well. The vibrations of the milling machine can cause nuts to come loose and fall into the milling machine. This can lead to damage to the tiller. If you still want to fasten the new brush with screws, do so at your own risk. In any case, make sure that you Self-locking nuts use. In addition, the screws should protrude as little as possible and have a countersunk head. You are responsible for any damage to the tiller caused by improper maintenance.
  • 1 x hacksaw or heat gun

This is how it's done:

  • Remove the brush cup from the tiller.
  • Drill into the pop rivets from the outside. Take care to minimise damage to the brush pot when drilling.
  • Cut the new brush into suitable pieces so that they fit into the brush head from the inside, or use a heat gun to mould the brush.
  • Place the new brush in the brush pot and drill the corresponding holes in the brush.
  • Place a washer around each pop rivet from the inside.
  • Pull out the mandrel of the rivet with the riveting pliers until it breaks off.


Error description

The milling file does not arrive at the milling machine. The router is not able to find a routing file.

Cause of error

If nothing has been changed on the computers, the network connection between the milling machine and the computer is often interrupted. If the computers have been reinstalled, a path is often incorrect or a network drive is not shared.


  1. Make sure that both the computer of the router and the computer on which the GP router is running have a network connection.
  2. If necessary, restart both computers.
  3. Start the GP Manager
  4. Select "Analysis"->"Gp milling machine
  5. Make sure that the right-hand path specification contains the same path as in the remote programme of the milling machine under "Settings"->"Options"->"Control system". In the case of network connections, the paths may look different, but must refer to the same directory.Remote-Einstellungen-Optionen-markiert
  6. Is in the right-hand path "C:\Temp\GpTemp", there is usually a network problem. First try to resolve the network problem. In this case, the GP Manager saves the data in the GpTemp folder as the network drive of the milling machine cannot be found.
    Once the network connection has been re-established, you must restart the GP Manager once for it to apply the change.
    Is in the path "C:\GEBIOM_SQL\GPDATA\Fraese\CNC", there may be a problem with the INI file belonging to the milling machine. Unless the CNC Remote programme is also set to this folder.
    If you have made changes to the INI, check the INI file. If you have not made any changes and this is the wrong order, contact GeBioM Support.
  7. If the correct path to the milling machine is entered there, open the path in the file manager (on the computer on which the GP Manager is installed) and try to create a new file. Right click->"New"->"Text document". If the file cannot be created, enter the folder on the milling machine with "Full access" for "Everyone" button. If you can then create a file from the computer on which the GP Manager is installed, milling should work. Start the GP Manager and try to transfer a milling file again.

Error description

When the tiller reaches the rest position, it immediately moves to the limit switch.

Cause of error

An incorrect value has been entered when determining the zero point.


If you have determined the value for the zero point in the GP Manager, you must enter it with a minus sign. If you have changed the zero point and then this error occurs, you have probably forgotten the minus sign in front of the value. The milling machine triggers the limit switch. This is how you set the zero point correctly:

  1. Follow the instructions for determining the zero point
  2. Ensure that the remote programme is started on the milling machine and that there is a network connection between the milling computer and the computer on which the GP Manager is installed.
  3. Start the GP Manager
  4. Select "Analysis"->"GP milling machine
  5. Click on "Setting the zero point
  6. Enter the correct zero point in the dialogue that opens in the remote program.
