Sienci Labs Dust Shoe

To make dust collection easier for your LongMill, we spent the time to design it its very own dust shoe. The new Sienci Labs Magnetic Dust Shoe is a great add-on for your machine that can keep dust management easy! This dust shoe is designed specifically for the LongMill and works with 1.5″, and 2″ to 2-1/8″ hoses.

This dust shoe is a Z-axis independent style dust shoe designed to collect dust and debris efficiently.

The assembly is shown after the initial reveal in the following video:

Sienci Labs Touch Plate

This guide will help you set up and use your Sienci Labs Touch Plate with gSender or UGS. If you have a different touch plate that’s still a standard block shape these steps may help you set up yours as well.

Inside the package:

  1. One touch plate
  2. Red and black wire with banana plug and magnet (1.8m)

Step 1: Wiring and plugging in your unit

Your LongMill control board (the LongBoard) comes with a detachable two pin screw terminal on the Probe/GND pins. With a small flat head screwdriver, start by screwing the two bare wires into this terminal. Ensure that the red and black wires are in the correct spot as in the photo.

When properly wired, the red wire will be on the Probe pin and the black wire will be on the GND pin.

Next, plug the banana plug into one of the two holes on the touch plate. Ensure that it is well seated. You can pick the hole you want to use that helps keep your wires out of the way.

Ensure you have an end mill firmly secured in your collet. If you are planning on doing a probe on the X and or Y axis, make sure that you have at least 15 to 20mm of your bit coming out of the collet. For other notes on end mill compatibility, please go to the end of this guide.

Attach the magnet to your end mill. You can also attach it to the collet nut or another part of your router or spindle as long as you have a conductive path through your end mill.

At this step, you are ready to start setting up your touch plate!

Step 2: Setting up software probing

You can choose to use gSender or UGS (UGSPlatform) to run the probe. We recommend gSender as it is easier.

gSender

gSender comes pre-loaded with all the settings needed for our touch plate and is able probe easily in the X, Y, and Z-axis and some other combinations.

All probing happens in the Probe tab in the main window. Here you can select what type of probing you’d like to perform as well as select the tool you’ll be using or you can type in the tool size manually.

  • Z: Finds the Z height only.
  • XYZ: Finds the zero point on the front,left corner of your material in all axes.
  • XY, X, Y: Finds the zero point in the X and/or Y directions only.

If you have a third-party touch plate, you can press the gear icon at the top right of the window to access the settings, which will pop up a window. Go to the ‘Probe’ settings on the left hand side. Here you’ll be able to customize your plate dimensions, the probing speed, or switch over to a Z-only probe.

You can also add tools here if you want the probe widget to remember your most commonly used tools.

UGS

UGS comes with a simple plugin that allows for your machine to send the commands to your machine to utilize the touch plate for finding the X, Y, and Z-axis.

Start by going to the top of your screen and clicking Window -> Plugin -> Probe Module. You will see a new tab appear on your screen.

Next, we will change a few settings. Click on the “Settings” button on the plugin.

  • Units: choose between millimeters and inches. For this guide, we will be using millimeters.
  • End Mill Diameter: the diameter of the end mill you will be using. You can find this diameter based on your manufacturer’s specs, or you can measure it yourself.
  • Fast Find Rate: the speed the machine will move to touch off the touch plate on the first pass. Set this to 150.
  • Slow Find Rate: the speed the machine will move to touch off the touch plate on the second pass. Set this to 25.
  • Retract Amount: how far your tool moves away from the touch plate on its first touch off. Keep this setting at 1.

Within the left side of the plugin, you’ll also see a few more tabs

  • XYZ: Finds the origin/datum point on the corner of your material in all axes.
  • XY: Finds the origin/datum point in the X and Y direction only.
  • Z: Finds the Z height only.

In these sections, makes sure that these settings are changed. If your section does not have that setting available to change, you can skip it. This means that in the XYZ tab you’ll enter all these settings, in the XY tab you’ll only use the settings pertaining to the x and y-directions, and in the Z tab you’ll only use the settings pertaining to the z-direction.

  • Probe X Distance: 25
  • Probe Y Distance: 25
  • Probe X Offset: 10
  • Probe Y Offset: 10
  • Probe Distance/Direction: -15 (make sure this value is negative)
  • Touch Plate Thickness: 15

Step 3: Putting it all to use

We’re pretty much ready to go!

If you want to run a probing operation, first we need to place the touch plate and set up the magnet. There needs to always be an electrical connection between the block and magnet for probing to work. gSender has a feature to check this for you, meanwhile UGS you’ll need to do this manually.

  • Make sure the magnet is attached to the collet nut of the Makita router.
  • For XYZ probing:
    1. Place the touch plate on the front left corner of your material. Make sure that both of the inner faces of the touch plate are contacting the edges of your material.
    2. Jog your machine to position the cutting tool about 10mm (½”) or closer above the circular logo on the touch plate.

gSender

Back in the ‘Probe’ tab, you can choose which axis to probe for and the diameter of the bit you’re using – in this case select ‘XYZ’. The bit size can be selected from the drop-down of saved bits, or can be typed in manually. Press the ‘Probe’ button and you’ll get a pop-up window to confirm you’ve positioned your bit correctly and you’ll be prompted to check for a good connection.

You can either bring the touch plate to the end mill or touch the banana plug and magnet together. Make contact a few times just to confirm there is conductivity, as the red circle should flicker to green and a blue ‘Start Probe’ button appears.

Pressing ‘Start Probe’ will now make the machine move to probe three sides of the touch plate, twice on each side. There should not be any crashing or abrupt movement. Once the process is over, remove the touch plate components from the machine and then press ‘Go to XY0’. The bit should be over-top of the bottom left corner of the stock material, and pressing ‘Go to’ next to the ‘Zero Z’ should bring it to touch the materials surface.

If the probing was unsuccessful, then it’ll be indicated by the cutting bit not returning to where you started the probe cycle or the machine will be put into an ‘ALARM’ state. To bring it out of the alarm state, press the pulsing ‘Unlock’ button in the middle of the visualizer and that will put the machine back into its ‘IDLE’ state. An unsuccessful probing cycle can result from an incorrectly positioned probe or starting too far outside the circular logo. Be sure to verify your setup before attempting another probing cycle.

UGS

Open up the probing window in UGS and in the XYZ tab press “Measure outside corner”. The LongMill will go through a cycle to probe and take its measurements.

If the probing function is successful, then the machine should return the bit back to the starting point where you initiated the probing cycle. You should notice that the digital readout (DRO) on UGSPlatform changes to reflect the measurements, the current position being offset a little in the X and Y and quite a bit offset in the Z.

You can check that it’s now zeroed on the material corner by first taking the touch plate off the material and removing the magnet from the router collet before pressing “Return to Zero”.

If the probing was unsuccessful, then it’ll be indicated by the cutting bit not returning to where you started the probe cycle or the machine will be put into an ‘ALARM’ state. To bring it out of the alarm state, press the “Soft Reset” button followed by the “Unlock” button and that will put the machine back into its ‘IDLE’ state. An unsuccessful probing cycle can result from an incorrectly positioned probe, the magnet not attached to the collet properly, starting too far outside the circular logo, and the probe not being plugged into the controller. Be sure to verify your setup before attempting another probing cycle.

If everything went according to plan, you should now see your bit hovering at the material corner like this:

Remove your magnet and set your touch plate aside, and you’re done!

Here are some other options you can use when probing:

  • For just finding the top of your material (Z):
    1. Flip your touch plate upside down and place it on top of the material that you want to find the top of.
    2. Position the cutting tool so that it’s above the indented part of the touch plate.
  • For XY probing:
    1. Place the touch plate on the front left corner of your material. Make sure that both of the inner faces of the touch plate are contacting the edges of your material.
    2. Jog your machine to position the cutting tool at the outer corner of the plate, lowered down from its top surface.
  • For X and Y probing:
    1. Place the touch plate on the front left corner of your material. Make sure that both of the inner faces of the touch plate are contacting the edges of your material.
    2. Jog your machine to position the cutting tool away from the X or Y face.

Concluding notes:

You may have some issues with using your touch probe if your cutting tool is:

  • Irregularly shaped (v bits, dado bits) and the side of the widest point of the bit does not touch off on the side of the touch plate
  • Non-conductive
  • You’ve entered the incorrect plate dimensions. You can refer to our own design below or the dimensions supplied by your third-party touch plate manufacturer:

Installing the LongMill T-Track Set

Here is a simple T-track set up that you can mount onto your work table. This is simply a basic guideline on setting up your t-tracks, but feel free to lay them out in whatever way works best for you! This layout minimizes reductions in cutting area and depth, and can be prepared in advance before your machine arrives. It uses a 48”x48”x ¾” MDF sheet, which can be purchased and cut to size at home or at your local hardware store.

  1. Cut a 48” x 48” x ¾” MDF sheet into five pieces of 6” wide planks, and two pieces of 5 ½ ” wide planks.
  2. Lay out the T-tracks and planks on the table, and fasten them down with wood screws. The machine will sit on top of the 5 ½” planks, as the 6” planks are arranged between them. They should be fastened with screws at least 1” in length. Leave about 1” of space between the screws and the ends of the MDF planks.
  3. To ensure your planks are flat against your table, drill counterbore holes in the middle of the 5 ½” planks. You can use the LongMill or a counterboring bit to create the holes, making sure you have removed enough material to recess the screw heads and surface the MDF planks at least 1mm deep. Then fasten them down with wood screws.
  4. Complete the rest of the Table Mounting process as described in the LongMill Resources page: https://resources.sienci.com/view/lm-table-mounting/
  5. Surface the MDF planks, as described in the LongMill Resources page: https://resources.sienci.com/view/lm-surfacing-wasteboard/
  6. Mount your clamps onto your newly installed T-track table, and enjoy!

Assembling and Using the LongMill T-Clamps

T-clamps are simple yet reliable workholding tools which are used with T-tracks tables. We’ve come up with T-clamps that work for various metals, plastics and woods, holding down materials from 0.1″ to 1” thick. These clamps are ideal for holding down small to medium sized pieces of material. Inside the package:

  • x6 steel clamps
  • x6 knobs with inserts
  • x6 3D printed end caps
  • x12 hex head machine screws
  • x6 flat washers
  • x6 T-track rails
  • 100 pcs wood screws

How to Assemble T-Clamps:

  1. Push the plastic end cap onto the steel clamp – the end with two holes. It should have a slight wiggle but should be not easy to remove.
  2. Fasten a hex bolt onto the other end of the clamp. We recommend the hex head to be facing upwards so that it easily slides into the T-tracks, but you can change it if desired.
  3. Slide the other hex bolt through the clamp slot, with the hex head facing down. Bring the washer and knob from the top, so that the washer is contained between the clamp body and knob.
  4. Now you can slide the downward facing hex bolt onto the t-track and locate the clamp for mounting material

How to Use T-Clamps on T-Track Table:

  1. Slide the hex bolt head through the T-track, so that the entire clamp is on the table.  You may need to adjust the bolt and knob to have it fit onto the table.
  2. Place your workpiece onto the table.
  3. Move and adjust the clamp to push down onto the workpiece, ensuring that the end cap side of the clamp is lower than the bolt end. Tighten both bolts until snug. Position the clamps so that there is enough space for your cutting job on your workpiece.
  4. Push your material to check if it is secured onto the table. If not, use more T-clamps or other workholding methods.
