  • Before commissioning, please make sure ALL of the following steps have been completed, before continuing!

  • Machine Assembly. ALL steps listed at the bottom of this page must be followed, in roughly the order shown.

  • Install Pronterface / Printrun.

  • Install the Marlin firmware into the Arduino Mega 2560.

  • NOTE: We're currently in the process of transitioning from Marlin to FireStep on the Arduino, for motion control. This guide is currently written for Marlin, but will soon be re-written for FireStep.

This guide will make heavy use of g-code (the protocol between the host software and the motion controller).  We are communicating to the motion controller with these low-level commands, which gives us a bit more power and flexibility during the commissioning phase.

  • Sanity checks before continuing:

    • Check for loose screws. Tighten everything.

Ensure that the ATX power supply power connections are made as shown in the first image. The other side of those wires should connect to the EMC02 motion controller.  The wires should be cable-tied to the frame, and clear of any moving parts.

  • NOTE: Currently, the 3D printing modular tool must be plugged in for the Marlin firmware to work. Otherwise, it will think that the hotend thermistor is reading too high, and will shut off. I'm currently working on a build that doesn't have this logic, but the changes are widespread and will be a while before it's fully tested.

  • For now, if you're not using the 3D printing modular tool, simply wire a 100K ohm resistor into the terminal strip where the hotend thermistor would go.

  • The 3D printing modular tool PCB should look like the picture to the left. Please refer to the 3D printing modular tool instructions to ensure that it is wired properly.

Launch Pronterface.
  • Launch Pronterface.

  • Select the COM port that the Arduino Mega is assigned to.

  • For baud rate, type in '250000'

  • Hit 'Connect'.

  • If this doesn't work, some common-sense troubleshooting will be needed. Ensure the Arduino is programmed properly. Ensure the USB port is connected and not in use by another app.

  • NOTE: We are only using Pronterface at this point for debugging. It's great because it gives us raw access to the motion controller so that we can troubleshoot and control the machine. Later, we'll run OpenPnP instead of Pronterface.

  • Send 'M80' in the pronterface input console. The red LED light on the FirePick Delta's ATX power supply board should light up after this command is entered.

  • Send 'M81' to pronterface. The LED should turn off.

  • Send 'M80' one more time to turn it back on.

  • Type 'M999' to reset any errors that happened while the power supply was off.

  • Each stepper driver module has a small trim potentiometer. This potentiometer sets the current drive to the motors.

  • This potentiometer setting should be a balance / compromise between:

    • High enough so that the stepper motor does not stall and lose steps

    • Low enough that the motor does not get hot to the touch (should not get past the threshold of pain, which is around 60 C or so)

  • Currently, I have mine set to 0.65 volts. This value is subject to change. This page will be updated if / when this value changes.

  • To adjust the trim pot, use a metal 1.5mm wide flat-head screwdriver, and place the DMM positive lead on the screwdriver. Place the negative lead on GND

  • NOTE: The standard tip of most multimeters will fit snugly in the ATX power supply's spare Molex 4-pin connectors. It is recommended to put the black DMM tip here, in the center two positons.

Type 'M119' in Pronterface.
  • Type 'M119' in Pronterface.

  • It should return:

    • x_min: open

    • y_min: open

    • z_min: open

  • Manually move the delta mechanism so that the "X" arm is touching the optical sensor. The amber LED should turn on. Type M119 again, and Marlin should report that the X optical switch is closed.

  • Repeat this for the other two axes.

  • Do not continue until all three homing switches work properly. Troubleshoot as needed if they are not working correctly. If you try to home without these switches working, the homing function will crash and could cause damage.

  • Ensure that the delta mechanism is roughly centered near X=0, Y=0.

  • Click the 'Home all Axes' or type in G28.

  • Watch the video for an example.

  • The delta mechanism should move all arms up to the endstops, and once the first one trips, it should sequentially home each one. It should look like the video in the left image area.

Neil, M80 and M81 are backwards in step 23.

Reef Morse - Reply

Reef, per my email on the dev list, M80/81 are not backwards (although if an older firmware version is loaded, it will appear this way). Mostly replying here for others that might have the same issue... best action to take is to do a git pull using the specified Marlin fork and branch, to main/latest, and try the commissioning steps again.. that should fix the M80/81 problem.

Neil Jansen -

In Step 29. I had to up the feed to G0E-90F10000 to get it to move like the video. Also are the stepper current limits different for the smt nozzle/ 3d print head?
