Hi everyone, I am about to run the wiring from an older denford compact 1000 CNC mill to the new black box that I've got. I noticed that the z motor has a device on it, which I believe I have identified as a z brake. I believe that it was originally wired up with 24 volt power. I believe a z brake is wired to turn on if the e-stop is hit. I am not familiar enough with the black box to see if there is an easy wiring solution for this. Does anyone have any experience with this?
Typically any motor brake is spring loaded and is "on" when the power is off, this is just to stop the z from falling when the motors are off. you would need to supply 24v to the brake when in use, solenoid pulls the brake off against the spring. So if the e-stop is killing the 24v then just wire the brake to the power supply no need for anything fancy. Cheers Gary
Thanks - makes sense for the sake of an e stop killing all power. Well I have it all hooked up but am just getting a little bit of clicking when try and jog axis on the control. Plenty more to troubleshoot!
Nothing I can see. Also I used a multimeter to find the pairs but I don't know what is+ and what is -.

Nailed it. Working now. Now I have to figure out how to change the direction of the motors the x jogs correctly but the y and z are inverted. My iot relay comes today for the spindle. Thanks for all the help
Control > Grbl Settings tab > flip the switches for axes that needs reversing under $3 Direction Invert. Also have a read through github.com/gnea/grbl/wiki - all the configuration values are well documented on the wiki
