General Mach Discussion / E-Stop Settings

« on: September 01, 2012, 12:10:38 PM »

I have a thread “New Build” which is related to the build of my new cnc but I’m starting this thread which will be related to the settings. I don’t know if its appropriate, pls correct me.

The E-stop is not working. I use the automated setup of inputs and Mach is picking pin #10 put this pin is taken by Y Home / Y- . So when I press the E-stop I get the message (Limit switch is triggered).

If I manually put pin #15 which it was suggested by others the E-stop is not working.

Also since the X & Z were travelling in the opposite direction, I ticked the reversed column in the Homing / Limits and now they travel in the right direction but I’m not sure if it is ok to do that.

I attach here my XML in case is needed

Thanks all  for the help

Yes I have the right resistor for each DB9 and all motors run good but have to tune them properly

The E-stop is connected to G540 as it should and it works, I just don’t get the interface I’m used to with Mack (pressing E-stop Mack needs reset)

Charge pump is also enabled

I replaced the connectors to the G540 with regular DB9 connectors and now the machine works good. Never used the G540 before and have these questions.

When I press the E-stop, nothing happens on the Mach screen, but the light on the G540 goes red and after a few seconds turns off and at this point Mach says and E-stop is active. Is this normal?

What is the CV Mode on the main Mach screen which is now highlighted?

Are any typical / normal settings for the motors with G540

HI ALL ,DO MACH3 AND MASTERCAM 5 WORK TOGETHER,ANY PROBLEMS?

I don’t understand what you mean by “work together, any problems?”

Mach3 works together only with LazyCam but will also load a G-Code generated by another program like MastercamX5 and execute this code

MastercamX5 is a CAD / CAM program which will generate the G-Code of your project. Then you can load this code to Mach3 to do the actual cut

Yesterday I got the power on for the 1st time and I got the green light on the G540

I was setting up Mach3 and about 10 minutes latter I smelled burning wires and noticed smoke coming out from the A axis DB9 connector and I shut it down.

I used the EZ-G540 DB9 connectors and after taking apart the faulty connector I noticed that one of the screws holding the 2 pcs together pinched one wire and sort it out. Don’t know why it took about 10 minutes to sort it out.

What is an alternate way to connect the motors to the G540?

Finally my new build was made with 1/2" thick aluminum plate / flatbar and other changes and here are some pics.

Cutting area is approx. Y=36”, X-26”, Z=8”. The gantry vertical pcs are temporary and new pcs will be cut in an “S” shape when the cnc is ready. Also the plate on the pushbuttons station is temporary and a new plate will be cut from 1/8” aluminum and all buttons will be engraved.

The rails and ballscrews are from China and all electronics / Taig spindle and Sherline motor / VS unit from Soigeneris

The table top will be either 1/4" tooling plate or aluminum plate

I’m at the final stages of wiring and hoping to start the machine sometimes this week

Thank you both, I will try without the caps

General Mach Discussion / Capacitors

On the previous cnc I had, I used a Probotix BOB and Hood suggested to install a 0.1uF ceramic capacitor between the + and – where the wiring from the limit switches were connected.

I'm doing the wiring now for my new cnc and since I use the G540, is it necessary to install these capacitors on the wiring for the limits again?
