Thank you for your comment,. I'm glad you found it useful.

Great, thank you for the feedback. Now go make some chips :-)

Thank you for your comment, always glad to hear that you find it usefull.

Hi, thank you for your comment. I'm not sure the 6040cnc offers that possibillity as standard to start/stop the spindle from MACH3, from what I can read in the manual and videos on youtube it does not. If you are up to it, most VFD's can me set up to Run/Stop via an input pin on the controller itself. But here you will need to refer to the VFD manual to set the right paramenters, and you will need a relay that is controlled from mach3. So M03 -> Relay activated -> Activates an input on the VFD -> VFD starts -> Spindle running. I don't know either the cnc6040 nor the VFD, so you need to go through the manuals and youtube. Best of luck.

Yes, I strongly recommend you do that. My breakoutboard does have opto-isolators but still the voltage spike from the relays would mess everything up and make the entire system unreliable. Pls. watch this video where I explain how to: kzfaq.info/get/bejne/j6yloa2jzLPFhIU.html&list=PLH2LdhXzCUgvWo3Wu5wuAJrXO6LiwnUV2&t=680

Yes, mach3 do have this documented. So you can run it with a PWM. However all of the cases where people it with PWM, I also see they have either a Breakout Board that supports is with a 0-10V output, or an external motion controller also with 0-10V out. The LPT-port will only give you 0-5V at best. I run my setup with an on/off relay, and just set the speed manually on the router motor itself, usually it's always full-speed when running in wood, plastics and aluminium with the small 1/4" and 1/8" cutters I use.

In some of the board use port 2 or 3

Thank you for your comment. I think not, output#1-6 is to be used. You do realize that you can use any port/pin combination to that output? Do not confuse pin numbers with output numbers ! Can you perhaps describe you problem, since you want to use other output numbers ? Running special macros or, but there you can also change the output number. Bo.

Yes I do realize I can declare output 1-6 any port/pin on the board. Someone before me created a macro for an ATC on my machine. Between that routing and coolant on/off it has consumed all of outputs 1-6. I'm trying to get M4 to work on the machine for tapping. Easiest route would have been to declare the m4 relay as an output > 6 but never the case Time to play with some macros!

Thank you for the reply !

OK, great. M4 is usually Spindel on CCW direction, ang G84 is ridgid tapping cycle. But what do I know :-) You can easily change the output numbers in the scripts your're using, since the output is the same throughout the program we can search/replace it. Try to send me the macrofile, i'll have a look. Bo.

There can be many reasons for this. Did you calibrate the Axis (Setting the steps/unit) correct. And also verify this numbers a couple of time. Else it can be back-lash in your system, or perhaps a weak construction. Please check this video on calibration: kzfaq.info/get/bejne/ia1dhbWhrtSlpKc.html

Hello. My spindle is working, but in the wrong direction (anticlockwise). How do I set it clockwise?

Copied my comment accidentally? :)

WTH ? What I meant: Which spindle are you using ? Is it a mains operated 1-phase, or 3-phase motor. Do you have a VFD (Varible Frequency Drive) ? Mach3, can only give an on/off signal to what ever controls the motor. If it's reversing I think you need to check the VFD, or mains wiring. But I need more info to help.

The 3 wires to the spindle are incorrect. Simply reverse two of the three wires.

If you set it up like I show in the video, then the G-code "M03" will avtivate the relay. Starting the spindle. And "M05" will stop it (or M30 as the program end command)

kalau nggak salah sih om ya.... kalau relay di disable berarti gantinya akan keluar signal 5v melalui P1
