General Mach Discussion / Re: which 2 wires to hook board to Variable Frequency Drive

Thank you, but maybe I'm in trouble then. I don't have any documentation on the VFD/inverter/(same thing?). I'm trying to attach an image of  the label is on it to this post.

General Mach Discussion / which 2 wires to hook board to Variable Frequency Drive

 You guys are awesome! Thanks to my last (& 1st) post I can now move my cnc in X, Y & Z.

Now I hope to get the VFD spinning. I replaced a control board in a big cnc machine I brought from China. The new board is an XHC-MK4:
http://www.automationtechnologiesinc.com/products-page/breakout-boards/cnc-mach3-usb-card-xhc-mk6-4-axis-motion-control-card-usb2-0-interface-wshell

The VFD had been connected to the original control board with TWO wires. On the VFD the wire connections are a blue wire connected to "S1" and a bit thicker yellow wire connected to "DCM".

Does anyone have any where I might connect these wires to the new control board? There are five spindle connections options on the card: PWM, FWD, 10V, VI, and COM.

I assume maybe one wire is for spindle speed and the other might be, for what, spindle on/off? Which do you think I should connect?

hi Dickey,
You're awesome. I just discovered that about the same time you posted it.

The Mach3 software didn't come on a disk. I was direct to download it here:
http://www.machsupport.com/downloads.php

I installed it, but the card driver, NcUSBPod.dll, isn't to be found in the Mach3 folder.

I googled NcUSBPod.dll, but not sure I've figured out how to find it yet. I found this page which may be the manufacturer. This page is mostly in Chinese, I'm downloading a 72mb thing now from there which seems like it might include this dll. It's a 2-hour download. whew.

plugin for the motion control card? None apparently came with it. It is not generic in that it says Mach3 right on it. I'll ask the vendor, Automation Technologies about the plugin. Wonder where/how else I'd check. Then the ports/pins, maybe they're on the stepper drivers(?) They would be set however they came from the factory. I'm happy to reset/check/tweak whatever, but who knows where could find instructions.

I assume the stepper drivers work, but if I had to I'd even replace them. That's why I replaced the control board because I thought I'd get tech support with it.

I bought a big, heavy-duty Chinese cnc machine. It came with type3 software. I couldn't interpret the Chinglish (minimal) documentation so I bought a USB2.0 MACH3 USB Card XHC-MK4, this one. I bought this new card thinking I could get tech support with it. I even paid an extra $50. for tech support. But I'm not so sure it will be coming.

http://www.automationtechnologiesinc.com/products-page/breakout-boards/cnc-mach3-usb-card-xhc-mk6-4-axis-motion-control-card-usb2-0-interface-wshell

I see $50. breakout boards. I thought this was a good quality one. I also bought a power supply from this vendor and a copy of Mach3 software. Then hooked it all up. When I try to jog one of the axes is the Mach 3 software it shows movement on the screen, but the machine doesn't actually move. I really need to get this machine going soon. Does anyone have a suggestion on how I can get the computer to actually talk to the cnc machine?? I can't figure out why it won't move. Can anyone here help diagnose or recommend a consultant or whatever. I am in Durham, NC, skype? phone, chat, email, help please!

Hopefully I won't have to replace more hardware. But bottom line is I need to do whatever is necessary to get this machine working. I have tried it with a 64-bit Windows 8.1 laptop and also with a 32-bit XP SP3 desktop. I see the drivertest.exe at 2.2.1 at:
http://www.machsupport.com/wp-content/uploads/2013/02/Mach3Mill_Install_Config.pdf

is that supposed to help diagnose with a usb connection or just a parallel port connection.

Friends, I'm feeling kind of desperate. I'm not sure where to go for help. ANY and EVERY sugggestion would be greatly appreciated. I am not a total dunce, I've build half a dozen computers and successfully used a shopbot cnc machine for a decade, but no longer have it.
