i purchased a used cnc router that i know nothing about. firs one i have seen not on you tube. any way have hours watching videos and they seem to
skip some things that they must assume i would know. the machine has mach 3 and 4 on it. v carve pro also. when in mach 3 videos say to jog machine
to various locations to set offset starting point. do you have to select jog on? my emergency light is flashing and wont reset. went to diagnostic tab and under input's
emergency is flashing. not being able to move any axis i set soft limits large so machine doesn't think its beyond them. I don't know where to start.
i called art soft and opened a account. Tried help from there tech, only got suggestion to license the program myself. That is fine but i still will have the same problem.

Did you click the Reset button? If you don't get it out of reset, nothing else is going to work. You need to figure that out first before messing with anything else.

the machine doesent have a emergency stop switch. the company that moved it to storage disconnected some wiring.
i know i need one, will figure out where to connect to circuit board.

I believe Mach requires an input for the estop in order to reset. If you don't have an estop you can short out the pins on your breakout board, but you will have to identify in the settings which pin is associated with the estop.

It may be good to identify your breakout board manufacturer and read up on a guide of setting up Mach3. Also keep in mind, Mach3 is littered with bugs and is not supported with updates anymore. Some find it stable but others have problems.

Disable the softlimits, and worry about them later.

You can also disable the watchdog messages, which I'd recommend.

You need to make sure all the port and pin settings are correct, and the axis are enabled.

Hi Ken, take it one step at a time, Mach3 is a little confusing at first but you will get the hang of it. After you start getting progress, back up the entire Mach3 directory to a USB drive. Keep copying the directory as you improve the setup. Also write down motor control settings, the Step/Dir/Port settings etc. The last thing you want to do is to redo everything should the PC crash...

Good luck with the new machine - fun and frustrating, been there, still there LOL.

Regards,

Steven

finally got mach 3 installed with my own license, also got ess working,communicating so i believe it should be going soon.
the original builder wires the ess board to the motor controlers with two wire shielded wire and used the shield as a connection?
dont like that idea, going to change it. also has 5,12,24,36 and 48 volt power supplies? 5 for the ess board. 12 and 24 to nothing.
36 to z and 48 to x/y. this is a 24 by 36 machine. i would thing the 48 should cover all three stepper motors? any thoughts there?

That's not a good idea at all, good that you're going to change it. I guess it depends on how robust the 48v power supply is relative to the current draw of the steppers as to whether it will handle all three steppers. Z typically doesn't run as fast as X and Y so is there a problem with the Z axis as it is now on 36v?
