Title: analog input voltage issues in Mach4
Post by: thespindoctor on April 08, 2018, 11:47:37 AM

Having trouble getting the correct voltage values in Mach4 from a Pokeys57E.

I measure voltage at the analog input pins up to 3 volts max but Mach4 registers only see about .8 volts max.

Does anyone have an idea what is going wrong.  Tech support has not responded with anything helpful yet.

Not sure if this is a Pokeys issue or a Mach4 issue.

Thanks so much.   Up against a deadline so getting panicked....

Reply from Polabs this is correct.  Register is fraction of total value. So 1=3.3 volts
