Looks like a maybe a major EMI or grounding issue.
Your odd voltmeter reading also suggests this.
Are the step/dir drives near the 7I96S?
How are step/dir wired to the drives? (single ended or differential)

My guess is that there siginificant coupling of the plasma start transient into the step/dir wires
or perhaps a grounding issue.
If you use single ended connections, the step/dir wiring will be less susceptible to
damage from external RFI/EMI. Another option is to use shielded wiring for step/dir
(with the shield connected to GND only at the 7I96S end)
