Asking a lot!

[IQChallenged]

(I had no idea when I prepared this pic that I would be posting it among lots of other wiring images.)

My hope is that someone can and will be willing to open my jpg with PAINT and click on the line tool (and choose red), and then connect my limit switches properly. I will also need to know how to set MACH. I'm also hoping the wiring will kill all axes with an open switch. I know I am currently operating my machine improperly wired. If X violates Y keeps on going and vice versa. I'd like for one violation to kill all three. Don't really care about the spindle. I only drew one switch per axis but I'm actually using two per. I assume that the diagram could be used either way. Told you I was asking a lot. Thanks in advance to anyone who can fix me up.

Hmmm....No numbers on the pins Dont forget the "E-stop" Here's my take on it. Oh have a look here too Mach Manual

[Mariss Freimanis]

For Mach3 and G201 drives:

In "Ports and Pins" select "Outputs Active Low".
In "Motor Tuning" select "Step Pulse Width" and set to "3 microseconds".

I so appreciate this. Just to make sure I understand-- you did mean that I would form a loop from the DIR to the SIG on the fifth block which has nothing attached to it at this time. Is that right?

And can I put a big E-switch within the same loop? Are they available in NC?

What pins?

Thank you, thank you, thank you.

I'd rather have the estop switch everything including the spindle off...But movement stops when a limit is triggered so it's nearly as good! (Check on Thinkoutsidethebox' thread for his verdict on using the estop) I don't know where you're going to attach it to on your board as I don't have the same one and don't know whether it's even an input :shrug: whichever input you use make it the same pin in mach3 and then test it. hth

I'm sorry to say I don't know what that means ("input"). I'm a picture kind of guy, thus the username.

Nice sense of humour/humor you have there...You sure you don't live around the corner from me? I like pictures too, so do you have one of your breakout board with the pin numbers on? (It's persistently raining here so I have time to kill lol) Or the make/model and I'll try and find one.

Here is an address with a pdf file explaining the board. It's wasted on me. I don't speak the language. I'm learning but that's not good enough. I could connect the wrong wires and smoke my board or who knows what all.

Here is a mental picture of the operation.

As referenced from the breakout board, an input would be a signal going from the machine "INTO" the breakout board and then to the computer to the Mach3 program. Limit switches or any other "INPUT" to the system are designated as inputs.

An output travels in the opposite direction, from Mach3 to the breakout board to the outputs which are step and direction.

There are dedicated pins assigned as outputs and inputs to the parallel printer port design specification.

Pins 2 through 9 are outputs.

Pins 10, 11, 12, and 13 are inputs. By the way, one of the four is inverted. Inverted means signal applied ends up being the opposite polarity of the applied signal. I don't remember which one from memory, and I don't have a picture or drawing to look at.


Example of Inverted signal:
+5 volt logic signal applied to input ..... Mach3 receives the signal as 0 (zero) volts or ground.

Verify your voltage polarity going to pin 10 on the Gecko 201. It is shown as connected to COMMON, but common what? Common +5 volts? Common ground? Your drawing should show the breakout board that you intend to use, with the pin numbers of the inputs, outputs, and so forth. Almost all breakout boards have subtle differences between them.

EDIT: THE CAMPBELL BOARD INFO WAS NOT POSTED WHEN I STARTED THIS ENTRY.

Looks simple enough 64 eh....Hmmm wherabouts did you visit back then...............Daddy Limit switches attach to J10 11 12 13 Homing to J6 7 8 9 and you use a NC (normally closed switch) Limit switch connections are from pin sig to pin gnd with homing from pin-2 to pin -3 and you should see on the diagnostic screen in Mach that the required "led" illuminates for all the above. The testing is advised to be done without motors/drivers attached!!! The board looks good (and the guys on the Campbell site remind me of the 2 guys from "tooltime" on ABC1) I found This Manual to be quite good. You want to revisit before you die! Better hurry up as we're having severe flooding at the moment
