Re: Acorn output states not changing. Possible fried Acorn?

Just wanted to post an update to this issue. I installed a new acorn, and decided to triple check my wiring from the acorn to the Delta Servo drives. I had two pins incorrect.

I have a geckodrive G213v stepper drive, 70vdc ps and a stepper. I will try that and see.

I have an oscilloscope, but only the faintest idea on how to use it. Its a 100mhz digital techtronics.

Morning everyone. Happy holidays! I have been working on getting my lathe running with an Acorn and Delta ASDA-B2 drives. for the moment, the Z is the only axis I have hooked up.

Re: In Preperation for hooking up Delta ASDA-B2 to Acorn.

The (NB1-D10-2P) shown in the legend appears to be the following CB- https://www.ebay.com/i/1844074...
