ZenBot 4x8 CNC Router

A few pictures of a stepper driven ZenBot 4x8 CNC Router I recently upgraded. It came with the original ZenBot "Control box" which consisted of a Gecko G540 4 axis stepper drive, and an AC "Power Brick" with an Estop button on front. Originally designed to work with Mach3. The owner met another one of my customers that I upgraded his CNC router to Centroid Acorn and it was suggested he go the same route after not being able to get Mach3 up and running.

I only reused his Gecko G540, installed a decent 48VDC switching power supply. Since we were driving the G540 to its full capacity, I added a heatsink.
The customer provided the cabinet which was designed for a G540. It was tight but I got it in. A solid state relay turns on and off the router motor. Two separate fuses, one for the control and one for the router motor. The power cord was upgraded to carry the current.

Incidentally, when the owner saw me using a wireless MPG while setting up his machine, he was sold on it. He realized where his monitor and keyboard were, he would be doing a lot of going back and forth to setup his parts.

A few pictures:

Nice! I would have expected to see a shoehorn laying next to the screwdriver. ;)

The controller box looks very clean and I think I might borrow your grommet idea for the DB25 cable.
I've got a few G540 setups and hand soldering DB9s is fine but doing passthrough with GX16 or the like complicates it too far for my limited skills.
