[Emc-users] OT - handling a 120v ac dip
I am just a tinkerer so I'm looking for advice. I have a project using an ESP8266 to control a light. I am using a Panasonic AQY280EH to switch the light. What is the safe protocol for mounting and connecting a device that is using a high voltage. -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

[Emc-users] ot: small drilling

I found them on Enco, http://www.use-enco.com/CGI/INPDFF?P...MITEM=290-1291, but they are a bit pricey for my needs.

I now want to use a 5i25 to drive the stepper board. Can you point me to a how to doc. The first thing is to see if theres standard configuration that matches the pinout of your 4 axis stepper board. Take a look at the pinout files for these standard parallel port compatible 5i25 configurations: 5i25_dmmbob1x2.pin 5i25_g540x2.pin 5i25_mx3660x2.pin 5i25_prob_rfx2.pin 5i25_r990x2.pin (they dont have to be an exact match, encoders and PWMs can be disabled, allowing the pins to be used as inputs or outputs but you want the step/dir pins to be correct) These files are part of Mesa's 5I25 firmware distribution in http://www.mesanet.com/software/parallel/5i25.zip The board I have is the Probotix "PBX-RF RF Isolated CNC Breakout Board". The 5i25_prob_rfx2.pin looks close. I attached my stepconf file.
