StrikeCNC Machine - My Retrofit

[Shinobiwan]

The electronics, whilst functional in the original Strike machine, weren't giving me the speeds I'd have liked. These were upgraded for better Leadshine AM882 drives along with higher volts (75v). What wasn't acceptable was the dangerous wiring job by Strike. Things like the 240v wired through the e-stop, bare wire hanging out of screw contacts, broken wire insulation exposing dangerous DC voltages, no cabinet ground and incorrect colour coding on wiring. It was a death trap basically and would never have passed any sort of safety test.

So I ripped the lot out and started from scratch with standard and sound safety practices such as e-stop on relays, home/limit switches, star grounding, cable management etc.

Strike's attempt:



After the upgrade:



I upgraded all the stepper wiring to shielded whilst I was at it too. Nothing more annoying than RF and EMI noise problems and the WC spindle can give off a fair bit of that.
