This weakened the nibbler a bit, but hey, who needs strength for cutting plastic? Did I mention that I'd modified this nibbler in the past to cut plastic? I made it so that its jaw would open wider. About an inch into the work, the nibbler broke. I scribed my cut lines, then started cutting with the nibbler. My original plan was just to use a nibbler, starting at the hole for the phone jack for the UPS.
Here's where the Gecko will fit, more or less. The Enclosure, after the guts were removed. After looking around at what I had on hand, I decided to "repurpose" an old UPS's enclosure: Yesterday and today I was working on an enclosure for my Gecko G540 driver and the power supply for it and the motors. I'm still getting it built up-I got my motors and motor driver three days ago and the A4 just arrived yesterday.
The next step is the worst part (imho) and that’s crimping header connectors onto 25 wires.I'm the proud new owner of a microCarve A4 CNC machine. No power supply required and no fan, the G540 is in a separate, cooled enclosure This combination of Arduino and cncshield will go in a small plastic box with a USB socket in one end and the DB25 cable at the other. This shield supports 4 x 8825 stepper drivers so each Y axis motor has it’s own driver I won’t be using any of these, I’ll just be using the cncshield as a way to interface the signals via DB25 cable from the G540 to grbl. Next I need a way to get the various control signals (XYZ step/direction, limit/home switches etc) from grbl to/from the Gecko. This thread will document the process of getting grbl to drive the Gecko G540 controller.įirst step was to get a couple of Ardunio Unos (if there are two Uno, does that make it a Due? ) They arrived from China today $A16 for both,Īs I’ve never run grbl before and all I know about it is from reading posts in this forum, a bit of reading was needed to get downloading the source code,compiling and installing on the Uno, A terminal program lets me run a $$ command and get a readable (if not yet understandable) response. However, I can’t access all the goodies that Easel provides unless I run grbl. It works well and I’ve been successfully creating gcode using (mostly) CamBam. I’ve mentioned in previous posts, that I run my X-Carve under Linuxcnc with a Gecko G540 controller.
