  15. Once done uploading you should have a screen that looks like this.

    • Once done uploading you should have a screen that looks like this.

    • Check that you are getting correct temperature readings (Celsius), ie. room temperature.

    Edit

  16. Go to Settings -> Fan Power up to 100% Both of the blower fans should start running.

    • Go to Settings -> Fan

    • Power up to 100%

    • Both of the blower fans should start running.

    Edit

  17. Go to Tools -> Move. Press the toggle switch to set motion to 10mm. Press the toggle switch to set motion to 10mm.

    • Go to Tools -> Move.

    • Press the toggle switch to set motion to 10mm.

    Edit

  18. X-Axis: Pressing the left arrow will move the bed to the right, and vice versa.

    • X-Axis: Pressing the left arrow will move the bed to the right, and vice versa.

    • This is correct as the nozzle position has moved in a negative direction relative to the platform.

    • Y-Axis: Pressing the down arrow will move the Hotend towards the front of the printer and vice versa.

    • Z-Axis: Pressing the double up arrow will move the gantry up and vice versa.

    • You will not be able to move to a positive position from your original starting position - this is normal.

    • If an axis moves in the opposite direction double check that you have uploaded the Proforge 2S Firmware if you are building with TMC2100 drivers. If you've uploaded the correct firmware and are still getting incorrect motion, see next step.

    • If an axis is not moving power down the printer and check steps 19, 20 and 21 relating to the stepper drivers and stepper driver jumpers.

    Edit

    • If an axis from the previous step moves in the wrong direction power off your printer and disconnect the touchscreen.

    • In the aruino IDE go to the "configuration.h" tab.

    • Scroll down to lines 855-858. (Go to File -> Preferences and check "Display line numbers")

    • #define INVERT_X_DIR true

    • Change true to false to switch the motors direction depending on the problem axis (X, Y or Z).

    • Re-upload the firmware.

    • Once uploaded, connect back the touch screen and power up the printer from the mains again.

    • Continue from the previous step.

    Edit

  20. Using the touch screen go to Tools -> Home. Home X With X homed the nozzle should land above the right edge of the print surface.

    • Using the touch screen go to Tools -> Home.

    • Home X

    • With X homed the nozzle should land above the right edge of the print surface.

    • If you find the nozzle not lining up correctly in the X direction adjust the endstop trigger to achieve better alignment. The distance between the end of the beam and the edge of the metal part should be approximately 6mm.

    Edit

  21. Home Y The nozzle should land about 1cm from the top edge of the print surface, this is OK.

    • Home Y

    • The nozzle should land about 1cm from the top edge of the print surface, this is OK.

    Edit

  22. If you have the Flexplate upgrade make sure it is on the platform before starting. Lower the gantry by hand so that the nozzle comes close to the print surface. Once close enough the red light on the probe should come on. The nozzle tip should always remain above the surface when the probe is triggered. The bottom of the probe should always remain above the tip of the nozzle.

    • Lower the gantry by hand so that the nozzle comes close to the print surface. Once close enough the red light on the probe should come on.

    • The nozzle tip should always remain above the surface when the probe is triggered. The bottom of the probe should always remain above the tip of the nozzle.

    • Nozzle too close or hits the print surface before the red light on the probe comes on:

    • Lower the probes position on the mount and check again.

    • Red light on probe but nozzle tip is too far away from the print surface:

    • Raise the probes position on the mount and check again.

    • The optimal position of the probe is around 18mm from the bottom of the probe and the bottom of the lower nut as shown in the 3rd image.

    Edit

  23. The Proforge 2/2S features automatic bed-levelling but to help get more accurate results we need to first make sure that the bed is physically as level as it can be. Adjust the z-motors so to get the distance between the nozzle and print surface along the y-axis (gantry) equal. Use a folded piece of paper to feel the gap between the nozzle and print surface.

    Edit

  24. Next use the springs on the platform to level the print surface in the X-direction (or both the X & Y direction if you're building the Proforge 2). Turn the screw anti-clockwise to raise that corner of the platform. Use a folded piece of paper to feel the gap between the nozzle and print surface.

    Edit

  25. To check that the probe and bed is set up correctly we are going to Home all of the axes together. Using the touch screen go to tools -> Home -> Home All X & Y will automatically home first. Then the probe should move to the centre of the platform and slowly lower until it's triggered.

    • X & Y will automatically home first. Then the probe should move to the centre of the platform and slowly lower until it's triggered.

    • The gantry will go up at first and then begin lowering - this is normal.

    • Have your finger ready on the power switch to power off in the event of a crash. If you do crash the hotend into the platform re-check your probe postioning - it's likely too far above the nozzle and needs lowering.

    Edit

  26. With a successful Z Home go to Tools -> auto-level. Press ONCE. The axes will home again and the sensor will now go around the platform probing 9 points. Again, have your finger ready on the power switch to power off in the event of a crash.

    • The axes will home again and the sensor will now go around the platform probing 9 points.

    • Again, have your finger ready on the power switch to power off in the event of a crash.

    • Once the Auto-levelling has been completed, re-home all of the axes to return the nozzle to the centre of the platform.

    Edit

  27. Take the folded piece of paper and place it between the surface and nozzle. On the touch screen go to Tools -> Move and toggle the distance selector to 0.1mm. Use the touch screen display to lower the nozzle (z-axis) in 0.1mm increments until it begins to grip the paper.

    • Take the folded piece of paper and place it between the surface and nozzle.

    • On the touch screen go to Tools -> Move and toggle the distance selector to 0.1mm.

    • Use the touch screen display to lower the nozzle (z-axis) in 0.1mm increments until it begins to grip the paper.

    • Make a note of the Z height displayed on the top right of the touch screen when the paper begins to be gripped. (This value will be 3.00mm to begin with, this is normal.)

    • In this case it ended up being 1.40mm when the paper began to be gripped, but this value will be different for everyone.

    • When done raise the nozzle up about 80mm.

    Edit

  28. Take the included sample of PLA filament out of its packaging. Use the included pliers to cut a sharp end. Place the spool of filament onto the spool holder and feed the filament through the filament sensor.

    • Take the included sample of PLA filament out of its packaging.

    • Use the included pliers to cut a sharp end.

    • Place the spool of filament onto the spool holder and feed the filament through the filament sensor.

    • Press down the Idler arm and push the filament in through the feeder and through the PTFE tubing until it reaches the Hotend and you can't push it in any further.

    Edit

  29. Before powering up the Hotend make sure that the black PTFE tubing is pushed all the way down the Hotend, it should go into the Hotend by 6CM. Double check, as running filament through the hotend with the PTFE tube not all the way down will ruin the Hotend. On the touch screen go to Tools -> Preheat

    • Before powering up the Hotend make sure that the black PTFE tubing is pushed all the way down the Hotend, it should go into the Hotend by 6CM. Double check, as running filament through the hotend with the PTFE tube not all the way down will ruin the Hotend.

    • On the touch screen go to Tools -> Preheat

    • Heat the Hotend up to 200C.

    • Wait for the Hotend to heat up.

    • Caution - the Hotend will cause burns if touched while hot!

    Edit

  30. With the Hotend up to temp and the filament loaded, go to Tools -> Extrusion. This is the length of filament that will be fed, each time you tap the down arrow. This is the speed setting.

    • With the Hotend up to temp and the filament loaded, go to Tools -> Extrusion.

    • This is the length of filament that will be fed, each time you tap the down arrow.

    • This is the speed setting.

    • You should have a smooth and continuous flow of plastic coming out of the Hotend nozzle.

    • The extruded plastic will be hot!

    • NOTE: When powering down from a hot Hotend, power the hotend down first and let it cool to at least 100C before completely powering off - as this prevents the heat from rising up the Hotend with the absence of the fan cooling it.

    • If you are not getting any filament extruded check the extruder motor is turning in the correct direction (anti-clockwise) to feed the filament. See next step if your extruder is turning in the wrong direction.

    Edit

    • If an extruder from the previous step moves in the wrong direction power off your printer and disconnect the touchscreen.

    • In the Aruino IDE go to the "configuration.h" tab.

    • Scroll down to line 863. (Go to File -> Preferences and check "Display line numbers")

    • #define INVERT_E0_DIR false

    • Replace false with true to change the motors direction.

    • Re-upload the firmware.

    • Once uploaded, connect back the touch screen and power up the printer from the mains again.

    • Continue from previous step.

    Edit

  32. Go to Tools -> Preheat Press the extruder icon to toggle to the bed. Power on the bed by setting its temperature to 60C - typical for PLA printing.

    • Go to Tools -> Preheat

    • Press the extruder icon to toggle to the bed.

    • Power on the bed by setting its temperature to 60C - typical for PLA printing.

    • A red LED should shine on the back of the heated bed and it should begin to heat up.

    • Avoid touching the bed whilst hot!

Yeah i double checked that it was plugged in the right spot, and the power was on otherwise i could not controll the motors and everything else, i will try to reupload my touch screen firmware, maybe theres a problem cos i only got one extruder in the firmware even tho i took the 2s

Hey, first i have to say those are really nice guides, secondly i have got a problem with my printer fans (step 15) because they are working when i clip them to 12V but arent doing anything when I turn them on via the Settings as it is supposed to be

Raphael Lehner - Reply

Have you checked that you have connected them to the correct position on the board. When trying to power up the print fans from the touch screen you need to make sure that you are connected and powered from the mains too and not just the USB port.
