Sold. Thanks!

I just finished rehabilitating a full sheet machine so it's time for my quarter-sheet workhorse to go.

I have a Grunblau "Platform CNC" built from the second or third batch of kits he sold. See...

Okay awesome. I'll give this a go when I get back to the machine (it'll be a couple of days).

The spindle is cooled by compressed air so there shouldn't be a minimum speed for cooling. There's...

That confused me for a while too. If you look at the footnote on Page 1 - attached for your convenience - you'll see the note about the difference between the VFD-A series and the VFD-H series, both...

Sorry for the confusion. They're not set at 60Hz. They're at 600Hz per the motor's nameplate (image below).

I've attached an image of said nameplate for completeness, but it's a 600Hz, 21.5A,...

Thanks!

So I was really at a loss for how to stop the thing without cutting the power since it just wasn't stopping on its own. It might have gotten there eventually but it sure didn't seem like...

Hi,

I'm refurbishing a machine that's equipped with a Colombo 5.5Kw spindle and a (now discontinued) Delta VFD (VFD075H23A) Manual Here

The spindle/VFD were fine, but the rest of the...

Hi,

I've got a quarter-sheet CNC Router that was built from a kit. It uses stepper motors via a G540 via a parallel cable to a PC with Mach3. The spindle is a water cooled chinese unit...

I can find absolutely no info on the motors, unfortunately. The only marking on them is "T31-25." Anyone know anything about these?

Did you get this to work? I'm in exactly the same boat right now and would love to get the skinny on what you did to get it working.

Thanks!

Okay. So I think we're not in the same page with respect to where the problem is, but let me provide some more detail.

The spindle is an UgraCNC (Chinese) 2.2kw, water cooled model.
The VFD is...

Sorry for bit clarifying earlier. I've got a Fuji Frenic-Mini VFD and a 2.2kw spindle from UgraCNC.

The G540 is connected using the screw terminal pins 7, 8 and 9 to the 10v out, common and...

[Please forgive the double-post. I don't really know if this is a Mach problem or a Gecko one, so I'm posting in both places.]

Hi, Folks.

I'm setting up my machine and I've run into a really...
