AMB C1 Initial Setup

	Difficulty Medium
	Steps 22
	Estimated Time 40 minutes

Step 1: Handling the Printer

Do:

Carry the printer with two hands.
Lift the printer from the arm base and steady it by holding onto the Z Axis rail.

Do NOT:

Lift the printer by the bed or bed frame.
Hold onto the Ball screw (try to touch it as little as possible)
Hold on to the printer by the arm.
Hold on to the cable chain.

Step 2: Setting up WiFi for the printer

There are three options with this step:

Connect the printer to your computer and use the AMBOTS connecting assistant.
Remove the printers SD card and enter the network info into the runonce file.
Connect the printer to your computer with a USB cable and input the network info over a command line. If you have a micro SD card reader we recommend the SD card option as the simpler choice at this time.

The printers can only connect to 2.4Ghz WiFi channels.

With Connecting Assistant

Make sure the printer is powered off.

Download the AMBOTS Connecting Assistant here.

Launch the AMBOTS Connecting Assistant.

Plug the included micro USB cable into the control board and your computer.

The status LEDs should light up on the control board.

Click the refresh button in the connecting assistant.

There should be a new com port show up in the console.
Select the new com port in the drop down.

Input your WiFi SSID and password into the respective boxes.

Click the “Set up Wi-Fi” button

The WiFi LED on the Duet should start blinking and go solid once it is connected to the network.

The console in the connecting assistant will also show when the wifi is connected.

Click the disconnect button in the connecting assistant.
Unplug the printer from your computer.

With SD card

Make sure the printer is powered off.

Eject the SD card from the control board by pressing the card into the slot until it releases and pulling out the card.

Insert the card into your computer.

In file explorer there will be a similar set of files as shown.

Open the “sys” folder

Open the “runonce.g” file into a text editor. (you will likely have to make a new one if the duet has been started)

The template for the file is as follows:

M552 S0							;Turn off wifi
G4 S3
M587 S"AMBOTS" P"ambots2020"	;Set wifi info
G4 S3
M552 S1							;Turn on wifi

Look in the line that starts with “M587”

change the text in quotations after the S parameter to the desired network ID.
change the text in quotations after the P parameter to the network password.
Example image would work for a network with ssid network and password 12345
Save the file as “runonce.g”
Eject the SD card from your computer.

Insert the SD card back into the printer and continue to the next step.

When you power the printer on the runonce file will run, then be deleted. if it does not connect to your network you will have to put a new runonce file in the SD card or try option #2.

With USB Cable

Make sure the printer is powered off.

Download / open a command line interface program.

Pronterface - an old program, but we still use it for this type of use case and have success with it.

Plug the included micro USB cable into the control board and your computer.

The status LEDs should light up on the control board.

Open the command line interface program and connect to the serial port the printer is on.

The console in pronterface should show that the printer is online once it connects and then start repeating messages that the WiFi module is not connected to anything.

Run this sequence of commands, one line at a time, replacing the text in the quotations with your network info.

M552 S0
M587 S"your network ID" P"your network password"
M552 S1

Pronterface sends text as all caps by default, so you need to put an apostrophe “ ' “ before each letter that is lowercase.

The green LED next to the WiFi module should start blinking and go solid green once it is connected to the network.

Once connected to the network the command line interface should also show a message in the console saying the printer connected to the network with its IP address.

Step 3: Powering the Printer

Plug the printer into the wall and turn the switch on.

Look for the following:

Row of LEDs on the Duet should light up

Driver LEDs should blink red and green, then stay green.

BLTouch should deploy and retract as it starts up and then stay red.

Filament switch light should turn on.

If other things happen turn the power switch off.

Step 4: Duet UI

amb-"printer number".local/

Go to a browser on a computer on the same WiFi network as the printer.

Enter in this address, replacing “printer number” with the ID number for the printer.

The address should take you to this page.

There should be a filament error you have to clear over the page.

The name of the printer should be in the upper left corner.

The two tools in the tool panel should show approximately room temperature.

Vin should show approximately 24V within 1V

Step 5: Starting the Setup Wizard

There should be a panel on the right side of the Duet UI with the header “Macros”

If you are accessing Duet UI from a mobile device the layout is different. I recommend using the desktop version of the site for this.

In the “Macros” section there should be a folder titled “Printer Setup”

Open the folder.

There should be a file within the folder titled “Setup Wizard”

Select the file

The file will start running immediately.

Step 6: Setup Wizard pt. 1- visibility

After Setup Wizard starts there will be a message pop up on screen to check that you can still see the temperature table behind it, as you will need to see it later.

If you can see the table, confirm the message.
If you can’t see the table cancel the message and the setup wizard will exit. Change to the dashboard tab in Duet UI or adjust your screen window so you can see the temperature table before restarting the setup wizard.

Step 7: Setup Wizard pt. 2- endstops

After the previous message is cleared a new one will pop up to press the proximal switch.

Press the proximal switch by hand.

The message should go away.

If the message does not go away the endstop may not be connected.

Check the Status tab to see if the X lights up green when you press the switch.

If it does not there may be an issue with the connection of the switch.

If it does there is something wrong with the Setup wizard. restart the printer and check the firmware version.

After the proximal message, a new message should pop up saying to press the distal switch.

Press the distal switch by hand.

The message should go away.

If the message does not go away the endstop may not be connected.

Check the Status tab to see if the Y lights up green when you press the switch.

If it does not there may be an issue with the connection of the switch.

If it does there is something wrong with the Setup wizard. restart the printer and check the firmware version.

There should be a new message pop up saying the endstop section passed. Clear this message to go to the next section.

Step 8: Setup Wizard pt. 3- motors

A new message should pop up saying the proximal arm should move away from the endstop.

Clear the message and watch the arm.

The proximal arm should rotate 5 degrees away from the endstop.

If the arm does not move there is something wrong with the wiring or config.g of the printer.

If the distal arm moves the drivers are switched.

If the arm moves towards the endstop the direction of the motor is reversed.

A new message should pop up saying the distal arm should move away from the endstop.

Clear the message and watch the arm.

The distal arm should rotate 5 degrees away from the endstop.

If the arm does not move there is something wrong with the wiring or config.g of the printer.

If the proximal arm moves the drivers are switched.

If the arm moves towards the endstop the direction of the motor is reversed.

A message should pop up saying the Z should move up.

Clear the message and watch the arm.

The Z axis should move up 10mm.

If the arm does not move there is something wrong with the wiring or config.g of the printer.

If the arm moves down the direction of the motor is reversed.

A message will pop up asking if the motor check passed.

If so, confirm and continue to the next section.
- The hotend heater will turn on if you confirm.
If any of the described errors occurred hit cancel and address them.

Step 9: Setup Wizard pt. 4- heaters

The hotend should start heating up to 50C and a new message will come up.

Watch the temperature to see if it is going up.

Watch the hotend fan. It should turn on one the temperature is above 45C.

If the temperature rises and the fan turns on hit ok.

If the temperature does not rise there is an error in the wiring or config.g with the heater or thermistor.

If the fan does not turn on then there is an error with the wiring or in the config.g with the fan.

The hotend temperature will change to 200C and the bed heater will turn on to 50C.

Watch the temperature table to see that both temperatures are rising.
Wait for the temperatures to settle before continuing.
If both heaters reach temperature hit OK.

If the bed temperature does not rise there may be an issue with the wiring or config.g of the bed.

If either heater has a fault error then there may be an issue with wiring, config.g setup, or the heater curves in config.g.

A message will come up saying the extruder check is next.

Hit ok to go to the next section.

Step 10: Setup Wizard pt. 5- extruder

A message will prompt you to insert filament into the hotend.

Push the extruder lever to the open position.

Take a spool of filament and put it on the spool holder.

Feed the end of the filament through the filament guide.

Insert the filament into the extruder.

The light on the filament sensor should turn off.
Push the filament in until some starts to come out the nozzle.

Lock the extruder lever in the first engaged position.

Clear the message in Duet UI.

A new one will pop up asking if filament is extruding.

The extruder should start to pull in the filament and start extruding out the nozzle.

If nothing happens then the extruder motor wiring is incorrect, disconnected, or there is an issue in the config.g file.

If the motor ejects the filament back out the extruder, then the motor direction needs to be flipped in the config.g.

If the extruder successfully extruded filament, clear the confirmation message.

A message will pop up saying the extruder check is complete.

Clear the next message to go to the next section.

Step 11: Setup Wizard pt. 6- filament sensor

A message will pop up asking you to remove the filament from the extruder.

Push the extruder lever to the open position.

Pull the filament out of the extruder.

The light on the filament sensor should come on.

Clear the instruction message.

An event notification should take it’s place saying that a filament out was detected.

If the light does not come on and the event notification does not appear then there is a wiring issue with the sensor.

If the light comes on but there is not an event notification then there is an issue in the config.g or the sensor is plugged into the wrong port on the Duet.

If the event notification did appear, clear it.

It should be replaced by a message asking if the notification worked.

Clear it to go on to the next section.

Step 12: Setup Wizard pt. 7- part fan

The part fan should turn on.

Confirm this by either looking under the distal arm or touching the fan.

The hotend is likely still hot at this time.

If the fan is on confirm.

Clear the next message to go to the next section.

Step 13: Setup Wizard pt. 8- BLTouch

The BLTouch probe should deploy.

The probe pin will extend.
The red light in the BLTouch will turn off.

Confirm if the probe deployed.

If the probe did not deploy

Check the connections. There may be an issue with the wiring.
- The BLTouch may simply have a bad connection to the Duet, not necessarily that something is incorrectly wired.
The BLTouch could be connected to the wrong port on the Duet.

The probe should retract.

The pin will retract.
The red light will turn back on.

Confirm the BLTouch is working.

If the BLTouch deployed but did not retract.

The BLTouch could have a weak connection with the Duet.
It’s possible there is an error in the setup files for the BLTouch in the Duet.

If the BLTouch retracted confirm the message to go to the next section.

Step 14: Setup Wizard pt. 9- homing

A message will appear notifying that the printer will home after the message is cleared. Read this sequence before clearing the message.

What should happen:

Z axis moves up.
Both joints move towards endstops.
Joints stop once they reach endstop.

If the joints don’t stop they will error out the drivers, you can see this has happened if a red light starts flashing on the driver.

Proximal arm moves away from endstop and back to it.
Distal arm moves away from endstop and back to it.
Arm moves to the center of the bed.

If the arm moves somewhere else there is a problem in the config file

BLTouch is deployed
Z moves down to bed.
Z stops once BLTouch hits bed.

If the BLTouch does not touch the bed before the nozzle or the BLTouch does not stop the Z then the printer will try to bury the nozzle in the bed. Hit the E-stop button in the UI.
