Hi All. First post here.
My Carvey unfortunately has a fried X Axis driver and despite replacing the driver chip I’ve been unable to get it working.
With the cost of a replacement board at well over AU$1000 plus shipping (ouch). The logical solution (to me) is to replace the board with a generic GRBL CNC controller. This is cheap, accessible and a path well trodden.
There are many capable GRBL based solutions out there, many of which I have used before, so my post is not about what hardware to use, but just simply reaching out for some wiring info before diving in.
If anyone is interested I’ll probably likely use an ESP32 with CNCV3 Shield running ESP32GRBL or FluidNC. I have this exact setup on my Mill One and it works great. Wifi + offline operation are a big bonus not to mention that it’s easy to add a laser.
So, what I’m after is a schematic of the Carvey, or any info that might be of assistance with making the swap.
The generic stuff like axis limits is pretty straightforwards but the machine specific stuff like Spindle / LEDs / Button / Door switch controls etc needs to be figured out, which to do properly may take a complete tear down to access some of the components, which I would like to avoid if possible.
I have already reached out to support but at this stage I am waiting for a reply.
So if you have traced wires, sketched the wiring, figured out how the LEDs are hooked up or even just have photos of a disassembled machine, specifically the electrical connections / wiring, it will likely save me a heap of time.
I think that basic XYZ movement and spindle operation will be simple to get running but integrating the machine specific features needs a bit more care.
I suspect that the Spindle is simply a basic brushed DC spindle and that a generic DC speed controller can be used but some confirmation on actual specs / wiring / etc would help.
Thanks in advance
