Installation Video

Compute Module and Antenna Installation

Prerequisites

Having access to the rear of the machine is recommended for this installation.

Parts Required

• Raspberry Pi Compute Module CM4

• Four M2.5x5mm socket head screws

• Antenna

Tools Required

• 2.5mm hex bit or key

• 2mm hex bit or key

Procedure

• Turn off the machine.

• Unplug the power cable.

• Remove the Wi-Fi antenna on the back of the machine by unthreading it.

• Remove the back-panel leading to the electronics by removing the six M4x16mm button head screws.

• Carefully unplug the antenna wire from the old compute module. Do not pull with antenna wire to disconnect it, but apply a prying force directly to the metal portion of the connector.

• Remove the four M2.5x5mm screws securing the old compute module to the main control board.

• Remove the old compute module.

• Install the new compute module by carefully lining up the high-density connectors and applying force directly over them to mate the connectors. Be sure the connectors are lined up well before attempting to mate them.

• Plug in the antenna connector. This is done in a similar fashion as the compute module, make sure the connector lines up well and then apply force on the connector to mate it.

• Install the four M2.5x5mm socket head screws to secure the compute module.

• Reinstall the back panel.

• Install the new antenna, threading it onto the SMA connector.

Considerations

Be very careful with the high density connectors of the compute module and the fragile connector of the antenna wire. Both of these are prone to damage if handled without consideration.

Troubleshooting

MCU Unable to Connect

• After powering up, the control software may need to be configured to match the machine’s physical hardware. If you get a connection error such as the following, you will need to edit a configuration file:

• First, log into the machine web interface, then open under the ‘machine’ tab open features.ymlfor editing:

• Replace the line mainboard: manta-m8p-v2-0 with mainboard: manta-m8p-v1-1, then click “Save and restart” in the top right corner:

• You will be asked if you want to regenerate the printer configuration. Click “Save and generate”:

• The printer will restart and be ready to use after a few moments.

Move out of Range Leading to “Cancelled” Print

• The default axis limits in the features.yml file are X300 Y307.5 Z300. This leads to “cancelled” prints where the end g-code in the slicer asks for a Z position larger than 300 which throws the error “Move out of range.”

• See this page for more information of editing the features.yml file: Modifying Features.yml

• To resolve this issue, set the axis limit for Z to 310 as below:

• You will be asked if you want to regenerate the printer configuration. Click “Save and generate”:

• The printer will restart and be ready to use after a few moments.

• Remove the lower gas-shock support by removing the two M4x18mm screws.

• Remove the gas-shock and support assembly from the machine.

• Once out of the machine, fully remove the gas-shock from the lower support and transfer it to the Camera Module Assembly.

• Install the Camera Module Assembly using two M4x18mm socket head screws with thread-locker applied.

• Reinstall the upper gas-shock support to the lid and tighten the locking nut.

• Route the two cables from the Camera Module Assembly through the top-plate where the cables for the Y-servo motor pass through.

• Install a zip-tie through the stand of the Camera Module Assembly to hold the cables and another to the servo motor wires near the top-plate.

• Route the USB cable all the way around to the USB port on the main control board and plug into the upper port.

• Secure the cable with a zip-tie.

• Route the other wire to the following connector near the previously moved/installed shorting jumper:

• Secure the cable with a zip-tie.

• Reinstall the 120mm fan with four M4x35mm socket head screws.

• Reinstall the cable track covers.

• Reinstall the rear panel with six M4x16mm button head screws.

• Reinstall the Wi-Fi antenna, threading it onto the SMA connector.

• Reinstall the side panel with eight M4x16mm button head screws.

Considerations

When removing one gas-shock the lid, one shock may or may not be able support the weight of the lid and it may fall uncontrollably onto you or the machine. Be mindful of this and either work with it supported or closed as much as possible.

Enabling the Camera

To enable the camera after the install, go to the settings panel on the web-console, scroll down to WEBCAMS and add a new Webcam. If the camera is plugged into the USB port it should be automatically detected. Give it a name and save and you’re done!

If the camera is not automatically detected it may be required to restart the Crowsnest service. This is the application that manages webcam streaming. To do so, in the upper-right corner of the web-console, there is a power button that lets you control each service of the machine. Click the restart for Crowsnest to restart the service. After, the camera should be able to connect.

Filament Switch and Entry Port

Prerequisites

Having access to the rear and right side of the machine is recommended for this installation.

Parts Required

• Filament Switch Sensor Assembly

• Three 18lb, 4” zip tie

• Two M4x40mm socket head screws

• Sensor Cable

• 150mm Length PTFE Tube

• One Filament Entry Port Assembly

• Two M4x16mm socket head screws

Tools Required

• 2.5mm hex bit or key

• 3mm hex bit or key (a short ball-end Allen key is recommended)

• Loctite 242 (or a comparable medium strength thread-locker)

Procedure

• Remove the filament and disconnect the filament storage container from the machine.

• Turn off the machine.

• Unplug the power cable.

• Remove the Wi-Fi antenna on the back of the machine.

• Remove the back-panel leading to the electronics by removing the six M4x16mm button head screws.

• Remove the cable track cover:

• Remove the 120mm fan covering the main controller by unplugging the fan from the power distribution board and removing the four M4x35mm socket head screws. You could also remove the three screws not near the fan’s wires and pivot the fan counter-clockwise out of the way, not having to unplug it.

• Remove the right side-panel to gain access to the filament entry port by removing the eight M4x16mm button head screws.

• Open the lid and remove the filament path between the printhead and the rear-swivel mount. The Filament Switch Sensor Assembly replaces this rear swivel mount.

• Remove the rear-swivel mount by unscrewing the two M4x40mm socket head bolts.

• Remove the filament entry port by unscrewing the two M4x16mm socket head bolts. This is when a short ball-end Allen key is useful.

• Fully remove the filament entry port and rear-swivel mount and PTFE tube between them.

• Install the newly supplied PTFE tube into the new Filament Entry Port Assembly.

• Install the Filament Entry Port Assembly using two M4x16mm socket head screws with medium strength thread-locker applied.

• Feed the PTFE tube up through the top-plate.

• Install the PTFE tube into the fitting of the Filament Switch Sensor Assembly. Be sure it fully seats within the assembly. Using gloves with a grippy texture is helpful (PTFE is slippery).

• Install the Filament Switch Sensor Assembly onto the tower using two m4x40mm socket head screws.

• Test the fitment with a piece of filament. You should be able to feed up through the Filament Switch Sensor Assembly without catching on anything. If you cannot, ensure the PTFE tube is fully seated in the Filament Switch Sensor Assembly and the Filament Entry Port Assembly

• Plug the Sensor Cable into the Filament Switch Sensor Assembly. It is keyed and will only plug in one way.

• Feed the wires down through the top-plate and into the electronics panel.

• Depending on what hardware you have will determine where to plug in the Sensor Cable, follow the guide below depending on your main control board:

• Once plugged in, secure the wires with a zip-tie.

• Reinstall the 120mm fan with four M4x35mm socket head screws.

• Reinstall the cable track cover.

• Reinstall the rear panel with six M4x16mm button head screws.

• Reinstall the Wi-Fi antenna, threading it onto the SMA connector.

• Reinstall the side panel with eight M4x16mm button head screws.

• Reinstall the filament path between the printhead and the new Filament Switch Sensor Assembly.

Considerations

Access to the screws that secure the filament entry port is quite limited. Using a short ball-end Allen key will allow you to remove/install it but it can be difficult. If more space is required, you can move the chamber air recirculating fan by unscrewing the four screws that pass down through the top-plate to the fan assembly. There are connectors leading to the fan assembly than can be disconnected and the assembly fully removed if necessary. This will give you more access.
