00:02 Dismantled original components for X Carve controller taking pictures along the way for your own reference.
00:58 Installed kettle lead panel mount and wired to PSU using crimp terminals. Depending where you buy your panel mount, the wiring may be different.
03:13 Connect 3 cord flex from power in terminal on PSU towards relay module.
04:00 I wired up a gang socket which would pass through the glands on the front panel, and connect to relay. I’ve drilled two as I am using a dual relay module.
04:30 I then connect the 24v power to GRBL shield via E stop. The E-stop is fitted on opposite end of front panel.
05:14 I drilled the holes for all the other front panel connections.
05:20 These include four 4 pin aviation mounts, which need to be soldered to lengths of 4 cord flex which will connect to stepper terminals on shield. (I’ve added two additional opening in anticipation for a laser module.)
06:56 Cut or disconnect original limit switch wires – keeping enough material to make connection within control box.
07:23 Wire ground and spindle enable to switch. If you are not planning to add a laser module you can take these directly towards relay.
08:14 In the video I pushed a tinned red wire into the 5V header but I later soldered this on. I then heat shrinked the wires together, adding DuPont header connections and fitting on relday.
09:31 Solder X, Y, Z and limits to male aviation plugs.
09:58 Add second power panel mount to back panel.
10:10 Testing the controller. Everything seemed to work but the relay was remaining on because the later version of the firmware assumed I was using a variable speed spindle. I had to change something in the config file and flash the shield. This useful blog walked me through the stages: http://goo.gl/B6IM3S
11:12 I now ran into another problem, as the relay always turned on when the controller was powered. The G code commands were also swapped. This could be quite dangerous, and I couldn’t figure it out so I asked Nathan from OpenTronic to problem solve this for me. He found another command in the Config file that had to be uncommented.
12:08 Now I will show you that it works, using a disco laser.
