I think we my have found the original print-out of the Nardini Fast Trace/Fanuc 20T parameter control data. Can anyone confirm that it (the data "Ladder") consists of 48 Bytes of 8-bit data?

I hope you still check this forum as I need the SRAM backup for the Nardini Fast Trace/Fanuc 20T if your still have them. Did you get copies of the manuals? I'd appreciate having a copy as well. ...

That is great news! Thanks for letting us know about your success and that the SuperPID folks reached out to you. They are awesome.

The cause would definitely be related to Super-PI's feedback loop becoming "open", i.e. not providing speed rpm feedback data. A blocked optical speed sensor would certainly fall into that category.

For clarification, my Super-PID is V1, yours appears to be V2. In my previous post, I posted a V2 diagram depicting connections that only shows PWM control signal coming from a PC (such as generated...

Also remember, that the other link I posted where Romanlini is discussing the use of Super-PID with the Gecko controller, he said the normal VFD+ reference voltage is 10volts, not 5. Using 5v worked...

I'd add the recommendation to measure the voltage from the super-pid 5v output to your VFD+ terminal to confirm that it is +5v. Then measure the output on the VFD Output pin as your CNC control...

Great!, Thanks for confirming. We have the same router but we use different break-out boards, so first I'll share my comparable screens that you posted in your setup. I use the CNC4PC C1R12...

Can you confirm that you have made the modifications to your PC 892 router for the optical RPM sensor feedback control?

Can you please provide more specific information for which Blackbox PWM switch you are using and why you would even need an IoT switch if you want to replace it with the Super-PID. What is the black...

I'm well familiar with the Arduino, primarily the Uno. As long as your Arduino PWM control line and the Arduino GND are connected as you show, it should be working fine.
In terms of what you are...

Super-PID V1 and V2 expects a positive going PWM pulse train between 0v-5v., where if the pulse train duty-cycle is close to 100% positive will result in the router running at its fastest speed.
It...

Sure, its possible, but it would require some diligent operation procedures. What a major hassle though. Think of all the connections that have to be switched from the one breakout board and the...

Al, I see what you are saying. Thanks



That's great news. Now, go have some fun!

I agree with Al_The_Man. The Arduino GND af it's 5V DC (and any other DC) supply should be connected to the DC or Signal GND of the SuperPID ...and let's be clear.... NOT in any way should any DC...

You mentioned an Arduino, is this taking place of the PC? Proper grounding between the PC or Arduino and the SuperPID is very important.

Which version of SuperPID do you have? Version 1 or 2? It matters as they each have different connection requirements. For now I will assume you have version 2 since you refer to it as "my new...

I agree with others, that this is a very unusual time, but it is great news that your order is coming your way. You are going to love your Super-PID. I've had mine for quite some time and love it...

Here's an update that I just encountered this now with my Win7 CNC that is normally ALWAYS standalone. A few days ago I installed the Autoleveller software which needed to download and update .NET...

I found the Porter Cable 8902 was fairly easy to modify. I may have also posted the mod process on this forum but I also posted it here: Build Your Tools ? View topic - Super PID

I use a Porter Cable 2 1/4hp router with my SuperPID.

I guess that goes to show that there is more than one way to skin a ground, err, err, ah, return current path. :)

All very true, and it is a working solution, there is no questions or argument about it.

It is my own preference to have more electrical isolation between the computer and the CNC BOB inputs and...

Very true Al and that is the very reason why it is unwise to power the SuperPID from the PC power supply.

You do not want to connect AC ground to DC grounds. DC grounds should be floating independent of AC safety grounds.

Roger that, Roger.

I am not familiar with other controller products but I have used Mach3 with my DIY CNC for years without issues. I know of many users of Mach3 with smoothsteppers without issue as well.

I think...

I've had and used a licensed copy successfully for 5 years but a few years ago had to move Mach3 to another PC with XP so I could upgrade my x86 quad PC to Win7. It's worked fine on which ever...

I'm thankful that this thread existed and that I found it!

I've used Mach3 for a number of years and never encountered this problem. My version is and has been R3.043.066 for the past 3 years or...

Great product, well designed, I highly recommend. I've used mine for four or five years with no problems or issues. I use a Porter Cable 890 with it currently and originally used a Dremel with it....
