Hi Reuelt,

If you consider my posting as a personal attack then I sincerely and unreservedly apologise.
(I also apologise for  any misspelling of your name).

I have sent you a PM by way of an explanation.

If MACH4 wants to be industrial, it cannot just remain at hobbyist quality.

Hi Rauel,

You don't need to concern yourself about the future of Mach4 - NFS have been in this business long enough to know exactly what they are doing.

I just hope I have given you the right answer - it's a long while since I had a screen size issue

General Mach Discussion / Re: Spindle Relay Configuration Questions

« on: May 02, 2019, 03:26:51 AM »

Hi LerninCNC,

You can even add a cheap "single-relay board" design for Aduino if you want to implement M4 for spindle counterclockwise spin if you use the unused pins (for the unused 5th axis) to drive a Aduino relay board.

The 5th axis direction pin is jumper selectable and can be used for either the onboard relay or external direction control – it cannot be used for both.

 

The BOB board must be powered by 12-24V otherwise the optically isolated inputs will not work.
USB connection is NOT required

A 5 Volt connection is required for the BoB and the USB connection from the PC is the easiest method.
And (as mentioned by Reuelt) a 12 – 24 Volt supply will also be required to power the inputs and the analogue output of the BoB.

I think it is better to switch the DC side of your spindle.
 

As already mentioned by ZASto this is extremely bad advice.
Ideally, using the BoB relay to switch the AC side of the motor controller via an AC switching solid state relay would produce far less electrical noise and cause less problems than taking any high voltage AC or high current DC to the BoB.

Hope this helps,

Tweakie.

They really piss me off.....I would still like to see all new members first post be moderated, at least it would give
moderators/administrators an IP address.

Hi Craig,

All new member's and contributor's IP addresses are already logged but when (as in this case) a VPN is being used the IP address is worthless.

In a matter of minutes in https://www.machsupport.com/forum/index.php?board=11.0 a "shower" of spam

Soo... Captcha SUCKS!

It took him (I assume it is just one guy) a little longer than minutes to register the new members and place the spam postings but I agree...  Captcha SUCKS!


I have requested that the registration Captcha be changed from the basic to the complex - maybe it will help.

It is perhaps as Craig has been saying all along, in many other postings - if you want accurate and reliable machining / probing / etc. then forget the cheap Chinese controllers.
