Hi John,

You need to change your Medium privileges so that it is not a 'Members-only Account' or find another platform for publishing your conversion process.

To require readers / followers to sign-up for an account (free or not) is not acceptable.

Hi Tweakie.CNC,

Thank you for your feedback.

I have changed the Medium privileges so these articles are not 'Members-only Account'. Please let me know if you have any other questions, comments, or feedback.

Nice website BTW (http://www.tweakie.byethost10.com/). You've really laid out the information on your CNC conversion very clearly in a manner that is easy for other people to follow.

Regards,

John O'Brien

Hi John,

Thanks for changing the Medium privileges – now I can continue reading how you used an op-amp in the multi-axis servo fault detection.  :)

Also, thank you for sharing your experiences with us as I am sure they will help and inspire others who may be considering a servo CNC conversion.

Tweakie.
