Unscrewing

Naked Power Close Up Too Close?

It’s now the weekend, If I can’t have fun playing with the CNC, driving it electornicially in the manner it’s intended, I’ll have fun with the screwdriver instead.

11 Philips head screws later (yep, these Cheap CNC’s are really screwed up well)

Some things of note

The Stepper motor driver board is labelled JP3163-B, uses Toshiba TB6560AHQ drivers. Looks like it’s only a 3 channel board

There’s a smaller stepper driver board on the side labelled JP-1635A. This looks like it’s fulfilling the 4th Axis role. it’s probably not on the main PCB as most of these devices will only ever be sold as 3 Axis….why spend the extra few dollars on un-used components.

The Variable Frequency Drive (VFD) Spindle driving Board is labelled JP-1482

There’s a HUGE HDB-200 (200VA?) toroidal transformer in there. centre tapped 18-36V secondaries.

Looks like there’s some googling to do tomorrow
