CNC Torch Table Testing Protocol

Ignitor Testing

1. Test 5V spark with 5V DC USB supply and cutoff USB cord. Use Helping Hands to hold wire, start with max separation and move in to determine max spark gap. Stop when you have sparks beginning.
   1. Take video clip, post on FB.
2. Use spark ignitor element with the above to see if the spark ignitor is activated.
   1. Take video - positive or negative results.
3. Test Neon light supply. Measure max spark gap as in #1.
   1. Video + FB post
4. Use neon light supply to see if spark ignitor is activated.

5. Set up torch in a holder to test ignition distance above table. Use acetylene only, no oxygen. Point torch to table at 1/2" away from surface. Place ignitor off to the side. Start with 3" away and keep moving away to see max ignition distance.
   1. Take video of ignition event. Take another video with max distance away, acetylene only.

Auto Ignitor Testing

1. Using 120V AC ignitor, test auto ignition using SSR powering the neon transformer. Connect transformer through SSR
2. Turn on gas manually.
3. Trigger ignitor via control panel to turn on flame automatically via control panel triggering. (take controller from old printer, add SSR)
4. Trigger ignitor via Lulzbot Cura to show computer-based triggering

Auto Gas Testing

1. Cut off torch end
2. Determine which gas line is which. Top 2 should be gas mix, bottom should be oxygen.
3. Verify that only one of 3 tubes carries acetylene.
4. Put the gas valve on that, 12 DC using D8 with Marlin Universal Controller
5. Trigger gas valve via D8 using screen (turn heat bed on)
6. Add 2 more valves. Test each as above at 12V.
