(showing TempoTreadle 1 System Unit)
Install the supplied brackets, spread evenly across the treadle span. The brackets fit between treadles that are connected with a round spacer.
To install the loom brackets, lift the loom a few inches and place the bracket under and around the wooden cross bar at the front of the loom. A helper will make this much easier since you must lift the loom and place the bracket at the same time.
Slide the sensor array under the treadles such that the long ribbon cable exits to the left and the array is centered under the treadles. Be sure to have the side with the sensors facing up. The first and last sensors are marked on your sensor array and should be directly underneath the 1st and last treadle.
Once again, you’ll need to lift the loom and carefully slide the sensor array forward so that the array is held in place by the brackets. The brackets will simply rest on top of the array so it cannot slide backwards or forwards.
A video for this setup can be found at
Next connect the ribbon cable coming from the System Unit to the Treadle Array ribbon connector. Carefully line up the pins, noting that the red stripe on the cable must be on the same side when connected. Press firmly to connect.
Connect the small end of the USB cable to the system unit and the other end to the AC adapter or USB battery.
You may want to place the System Unit on the floor as you perform install and align the magnets for easier viewing.
On the System Unit, select System Settings | Tune Array. At the top of the screen in red letters, observe that the display reads “Any Treadles”.
·A magnet inside a case has been supplied for each treadle. The extra "tuning" magnets are not normally needed.
Magnets need to be attach to the underside of the treadle using the supplied velcro such that when the treadle is pressed, the detection of is strong and steady.
Normally it's best to line up the treadle 1 first. It's recommended that you hold the magnet with your hand over the array until you see the treadle detecting, then go straight up and let the velcro attach to the underside of the treadle.
Next repeat the same step with the last treadle.
You should now be able to see how far back each magnet needs to be placed on each of the treadles.
Small adjustments left or right, forward or backward, may be necessary to get a good detection. There are small sensors for each of your treadles and the magnet must be lined up so that it's directly over these sensors when pressed.
When installing the sensor array on a hard surface, if you have difficulty getting a strong connection, add one of the supplied "tuning" magnets onto the magnet case. The magnetic attraction will automatically orient the magnet in the correct direction.
Be sure that the magnets are not touching the sensor array when treadles are depressed. The magnet should be moved back slightly to keep it from touching the sensor array.
The velcro on the magnet case should be holding firmly to the underside of the treadle.
If a treadle is not tied up, it is ok if it rests on the sensor array, however be sure to turn the treadle status off using Project Setup | Treadle Array.
If tied-up treadles are being detected when they are not going down, but moving slightly, then they are too sensitive; move the magnet case back slightly on the treadle. Also if using the additional magnet, remove it.
If some of your treadles have a lot of “play” and tend to shift left or right when treadling, you may want to tighten them. When you have a gap of more than ¼” or more when slid all the way to the left or right, insert a zip tie around the metal bar on each side to reduce any “play”. After cinching, cut off the excess zip tie and rotate so only the smooth side shows.
If the sensor array is coming out of alignment with left/right movement, you can put a small piece of Velcro or tape to the bracket to secure it from left/right movement.
Symptoms of Poor Alignment
· When weaving, if the you get an “ok” beep, followed by an error beep, look at the display and think about the treadle you are pressing. You may notice that the treadle is detected (showing in gold at the bottom of the display), loses detection, then detects again. TempoTreadle thinks you pressed the same treadle twice, and issues an error the second time. This can be a symptom of the treadle being marginally aligned. Go into tune array adjust the magnet (typically forward) to get a more solid detection. Also see the above troubleshooting tip if there is too much clearance.
Pressing Next Treadle before Prior Treadle is Lifted
· When weaving, if you see all the treadles from the prior pick as well as the next pick, and no error or ok tones after the prior pick, you are likely not letting the prior treadle lift far enough to end the detection (i.e. making a closed shed) before the next treadle is pressed. This can happen when walking the treadles on certain looms. If your treadling style is to have both pressed at the same time, the system will not work as it depends on a split second of nothing being pressed to check for errors and advance to the next pick.
4, 8 and 16-shaft
INSTALL MAGNETS
o Install the 16 rectangular magnets onto the levers by attaching the Velcro (remove the protective backing) to each lever with the magnet facing the weaver when the lever is in the up position. The magnet should be centered on the lever at approximately 1 9/16th inches (40mm) from the top of the lever. Use the picture to the left as reference.
PLACE TEMPOTREADLE AND CADDY ON THE LOOM
o Place the TempoTreadle System unit in the caddy on the left of the loom as shown.
o Plug the small end of the USB data cable into the top of the System Unit; plug the USB end into a USB power source or the provided AC adapter.
In your packaging for a 16-Shaft System Unit, there is an additional short cable as shown below. This cable is ONLY used when using a 16-Shaft System Unit on a loom with fewer than 16-shafts. Put it aside and keep it in case you want to connect your System Unit to another loom in the future.
It’s now time to attach the Sensor Array. The Sensor array has Velcro on the top and a ribbon cable exiting from the left.
INSTALL SENSOR ARRAY
· To attach the sensor array, remove the clear backing from the Velcro and place the sensor array under the castle (see picture) such that the array is centered and the cable on the left. Observe the 16-black sensors and line them up with the center of the 16-levers by tiling the array. Next, turn the sensor array such that the Velcro is facing up and press up to attach under the castle. It’s necessary that the array also be flush with the wood on the castle.
· Press firmly to attach the cables from the System Unit to the Sensor Array, making sure the red stripe is on the two cables is aligned as shown.
· With the system unit powered on, run a test by using the Tune Array function under System Settings to verify that all the levers work. Press System Settings then Tune Array. Flip the levers down and expect to hear a tone and see the lever number displayed. If all don’t initially work, adjust the position of the sensor array and/or magnets until they all do detect properly.
· You are now ready to put your own WIF onto the SD card and weave!
Initial Setup
· Loom Action in System Settings can be set to “Table” or “Table2”. When weaving with 8 or less shafts, the “Table” action should be chosen; for over 8 shafts, use “Table2”.
· When saving a WIF from your weaving software use the Lift Plan option. Copy or perform a “save as WIF” onto your SD card from your computer or use TempoWeave design software to Export for TempoTreadle.
· Most likely you’ll need to place the small micro-sd Card in the provided adapter. Eject the micro-sd card from your computer once the project is saved and place back in the TempoTreadle system unit.
Weaving
· You do not need to place all the levers in the neutral position between picks
· With “Table” Loom action, the weave screen shows three pick sequences. The one it is currently expecting is in the center, surrounded by a box. With “Table2” the levers needed are highlighted in blue, correct levers detected are green, incorrect levers detected are red. The weft color is shown in a circle of color.
· Lower the levers indicated on the center line, noting the weft color if you have color changes.
· Once you have lowered all the correct levers, TempoTreadle automatically sounds an OK beep, adds 1 to the pick counters and advances the screen to the next sequence.
· It is recommended that you place all the levers in the neutral position and press the Home icon when you take a break from weaving.
Unweaving
· You rarely need to unweave when using TempoTreadle, but occasionally you may have a weft bubble or some other problem where you do want to some picks out. To have TempoTreadle prompt you backwards through the sequence, first place the levers in the neutral position, then press “Weav” on the weaving screen (now it will show “Unweav”). Continue to unweave until you are ready to start going forward through your weaving sequence. Simply press “Unweav” on the screen twice so that it now reads “Weav” again.
· If you have only one pick to unweave, you may want to simply open the correct shed, back the pick out and then keep weaving without using the Unweave feature.
Selecting Menu Options while Weaving
· When TempoTreadle shows the weave screen, place all the levers in the neutral position (levers up) before selecting other menu options or pressing the weave/unweave button. If you don’t have the levers in the neutral position, the screen may seem slow to respond.
· Free Weave – Currently Free Weave is not supported when weaving on a table loom
Weaving a sample
· Once you start a new project, you often weave a few a sample to get a feel for your beat. Once ready to start the “real” piece, and weave a sample or header, you may want to select Project Progress | Reset Progress to zero the counters.
Symptom: No levers detect when using Tune Array
· Sensor array is mounted backwards. Be sure the cable exits to the left with the red stripe down.
· Cable is not plugged into the System Unit. Attach the ribbon cable end to the end of the system unit. Be sure the red strip is on the same side (forming a straight line as the two cables are attached).
Symptom: Some levers do not detect
· Check to see if the black sensor array is centered. You may need to move slightly left or right.
· Visually check that all the magnets are in line. Adjust if necessary.
· Be sure the sensor array is flush with the wood.
· Take a spare magnet and see if the sensor registers by holding the magnet over the sensor array.
Symptom: Weaving sequence will not advance until levers are placed in neutral position
· Check System Settings. Loom Action should be in Table or Table2 Mode and position Up.
Symptom: The screen blinks rapidly
· See if “Free” has been selected on the weave screen. Press the button to return to “Weav”. Also if “Free” can be selected, likely the Weave Mode in System Settings is not in Table or Table2.
Symptom: No Error beeps
· This is intentional on table looms. Only “OK” beeps sound when all the levers are in the correct position and ready for the pick to be thrown.
Slide the magnet caps onto the ends of each lever as shown. Ensure that the cap is slid all the way down, touching the round metal plate. If the magnet cap is not tight, place one of the provided glue dots on the wood and slide the cap back in place.
Extra Velcro will be included. Place a strip on the back of the magnet if cap is too loose.
Place the caddy connector over the top of the loom and then place TempoTreadle into the caddy.
Place the sensor array under the front of the loom as with the cable extending to the left. The small white marks on the array indicate the first and the last treadle. Line those marks under the magnets on the loom castle. The edge of the Velcro should be barely visible under the loom’s castle as shown in the picture. Route the Sensor array cable under the top of the loom through to the back. See photos at end.
**NOTE: The array pictured here is black, we have since switched to clear cases. **
Place the System Unit in the caddy.
Plug the small end of the USB data cable into the top of the System Unit; plug the USB end into a USB power source or the provided AC adapter. As with all Micro USB plugs, the plug is directional. The picture to the right shows the side that should be facing the front of the unit when you plug it in.
Connect the cable from the system unit to the connector on the sensor array. Press firmly to attach the cable from the System Unit to the Sensor Array, making sure the red stripe on the two cables is aligned.
Power on the system unit.
Select System Settings | Tune Array to verify that all the levers work. Press levers and expect to hear a tone and see the lever number displayed. If all don’t initially work, adjust the position of the sensor array until they all detect properly. Excess ribbon cable may be bundled with a rubber band.
Your system unit will arrive with a micro-SD card already in the unit. A loom profile, !Voyageur, has been preloaded on the card. Once the unit is powered on, the loom profile will automatically load. You can run a quick test to see how TempoTreadle works by selecting Weave and following the short lift plan. You should hear the “ok” tone when you have the correct levers engaged; at that point you normally would throw the pick. Now you are ready to use TempoTreadle.
