Thank you, Great video. Unfortunately i'm still having trouble getting my relay to work, I cant get a signal voltage high enough could I send you a schematic of what I'm trying to do?
Hi. Thank you for your comment. I do not have a MACH4 installation yet. But the wiring is the same as shown here. The only difference is the coding and pin assignment in MACH4 that is different. I hope you can find an other video detailing this. Best of luck. Bo.
Hi Bo. Your video is very helpfull and useful. In my first contact with cnc diy machines I started with arduino and in the gshield module we usually share the same port for the y axis if we had two motors moving the y axis. But in all video I watched for mach3 I saw they slave the port for A axis to Y axis to move two motors. Can we hook up both motors to one port so we can make free two additional pins ( 2 in fourth and 2 in fifth ) axis for extra relays? Or there's a matter of voltage when you use let say Strong stepper motors to hook up them together?
Hi Mario. Thank you for your comment. So, you can use one set of port/pin to control both stepper-drivers. And by that create a "slave" motor. Reason what I, as many others, choose to use a seperate port/pin for the slave axis, is the controller software can home the machine to 2 differet homing switches. one for each axis. This will cause the gantry to "auto-square" the gantry. So for example if one of the steppers is missing steps, for some reason, then you need to manually square it up, using only on port/pin setup. Where a true slave axis, does that for you. Hope this explains.
Hi I have watched your video several times now but unfortunately I am still having trouble. I have two questions the answer to the first will most likely help me to solve the second. On my breakout there is a relay that can be used to switch on and off the spindle. I have set it up as per all the instructions I can find but am still unable to get the relay to respond when I press the spindle start button . I can hear it working and it will light a bulb when I enable it from the config ports and pins /output signals and use the active high /low option to turn it on and off. Any advice will be greatfully received. The other problem relates to relays similar to the ones in your video I just cannot get them to work. thanks Ken
Hi Bo. You get a tick and a gold star for that reply. I had it working with 3 clicks in about 30seconds. What I had done was to enable the "enable1" button and not the output #1. Sometimes you just can't see the wood for the trees. I had also made the same error with the output for the relay that I was trying to configure to get the coolant for the spindle to switch on and off so hopefully I will now be able to get that to workas well. Once again thanks for taking the trouble to make that short and very informative video. Regards Ken
I'm not sure I follow you completly. If you have 3 spare pins on our Breakout-board (BOB) then yes you can use a 3-relay arduino board. If you look at eBay there are tons available. goo.gl/b2luuO
On your Breakout board you said you weren't using the 5th axis so you used Pin 4 I see now that you don't have 3 extra pins (pin 1 is shared) you only have P17 left, would this be able to be used for an extra relay?
Correct. My 5.axis is not used so I have 2 spare pins (What is normally used as STEP and DIR) You should see these pins as General Purpose pins. They are not dedicated STEP/DIR pins. That is only how they are named on the break-out-board layout. You can use any spare output pin to control what ever.
Thank you for your comment. The fly-back diode is recommended, as I started without the diode. But it totally messed up my controller and signals, it was unreliable. Untill I mounted the diode. Now it works as intended. So I HIGHLY recommend to install the diode.
I assume you want to connet a mains 110/230 VAC router directly ? If so, first of all be carefull ! Now make sure the relays on the relay-board are rated for your voltage and current. Voltage is normally either 110VAC (US) or 230VAC (EU) also the current of your router (Read the nameplate on the router) the rated current on the relay must be equal or greater. Now the connection is in the same way as on the 24V side as shown in the video. You take the mains live phase and connect it to the "Common" pin on the relay, and the NO-pin (Normally Open-pin) you connect to the router. The Neutral wire from the mains, connects directly to the 2.nd wire on the router.
The Enable Pins on the BOB is usually for the "Enable" on the stepper drivers. That way the Steppers can "idle" when you fx. press E-Stop. Be aware that the "Enable" pins all uses the same pin, so ALL enable output-pins goes HIGH/LOW at the same time, and cannot be controlled individually.
Really nice explanation !!👌 thank you very much 👍
Thank you for the film, this was EXACTLY what is was looking for!!!
Thanx a lot for what i have been looking for. Nice and very easy to understand video
Thank you so much for the help BO, your videos are very helpful.
Thank you for your comment, I'm glad you find it helpful.
Thanks a lot for this video I have been looking for this for along time i will now try to put it in action ...
Sounds great, hope you will succeed...
Excellent video Bo.
Thank you for your comment, I'm glad you found it usefull. And Happy New year .-)
Very cool. Thanks!
Thank you for your comment. Glad you found it usefull. :-)
Very helpful THANKS.
Very informative.
Thank you, glad you liked it :-)
Thank you . How to controll vfd speed
Thank you,
Great video. Unfortunately i'm still having trouble getting my relay to work, I cant get a signal voltage high enough could I send you a schematic of what I'm trying to do?
How can we wire 24V linear actuator at p17, and move forward and backward by mach3
Thank you
May you please do the same project using mach4 instead of mach3
Hi. Thank you for your comment. I do not have a MACH4 installation yet. But the wiring is the same as shown here. The only difference is the coding and pin assignment in MACH4 that is different. I hope you can find an other video detailing this. Best of luck. Bo.
sir please tell me how connect water coolant with this breakboad. I have 80 watt water pump. I don't understand diode. where we use

Bo Andersen Much obliged for your reply. Of course this explains the use of a slave axis.

Hi Kenneth. Awesome ! Glad I could help. Have a great weekend.
nice job so if i was to use this on my cnc plasma i could hook this into the triger wires
Hi Leon. I guess that should work to control the Plasma too. I don't have any experience in that though...
-Bo-
so did you use the disk that cam with it or whats it for
The disc that came with the Break-out-board ? That has the documentation on which terminals on the board goes to which pins.
hi
i want activ externel relay with Mach3 in output 14 how i will do
In your script you write "ActivateSignal (Output14)" to activate the signal. And "DeActivateSignal(Output14)" to deactivate.
Since you have 3 pins available is it possible to use a 3 relay ardunio board?

The arduno relay is optically isolated so there is no need for the diode on the

how would you connect router?

what do i hook to the enable pins
