Here I am two years later. . . and the Gravograph IS6000 Controller is on the fritz again.

It refused to boot up saying the Dongle wasn't present!
The lifetime Dongle warranty was voided because...

Why post under "Free Models" then expect donations and follow up with "Thanks? No Donation!" comments to some members who posted "Thanks!". Poor taste in my book and comes across as mandatory. Maybe...

I am selling a brand new HSD ES915 ISO30 ATC Spindle package on Ebay.

( https://www.ebay.com/itm/123321596807 )

It's never been installed and everything is brand spanking new. If you are...

YGOREK:

Cannot DOWNLOAD any of your files after more than 30 attempts on each one I tried.
Just goes to a site telling me I have to SUPPORT the Ad's to use the link.
Can't blame the members. ....

I got tech support on the phine. The Bro said it was a bad X Axis limit switch, so I ordered one 2 Day Air. Two days later, no limit switch. Called tech support again, and I got a different tech...

Can't afford a pot to piss in or a window to throw it out of right now. . . which is the biggest reason we needed to get this controller to Georgia on Friday and back here on Wednesday, so we could...

Controller on it's way back to Gravograph in Georgia. Traced the pins on the DB37 cable and the all ohmed just fine. Did the same thing with the motor wires and the DB37 cable. Tech said it's most...

Has ANYONE experienced this issue before?

I have a $10,000 job waiting on this IS6000. Today, when I went to start running the job, the engraver boots up fine and says "Ready to Receive" like...

No. I was tired and going to bed. Typo.

It is correct.
I have 190 - .375 inch deep x .5" diameter holes, milled into the PVC with an endmill.
I have 190 - .25" diameter holes drilled through the middle of the 190 - .375" x .5" milled...

Laser cut flat acrylic.

No gasket under the discs.

Haven't decided what I am going to do. NATO Rounds and Tannerite come to mind.

Gasketing is new.

I have wondered if a different supplier, other than Allstar, which is highly recommended, might be in order. . . or a different durometer.
Not sure what to think anymore, other...

Received the 400 plugs and installed 190 into the table.

I turned on the blower and got the usual 10 Hg with the ball valves closed.

I opened the ball valves and it dropped to 8 Hg with all the...

Thanks Eric,

Maybe after things calm down and I have time to teach myself VB, I will take a closer look at SAC.

Got the sample plugs. Will work perfectly. Had to order minimums - so 400 plugs on order. Should be here next week.

I have a couple of sample plugs on the way already. Should be here end of the week. After that I order the size that fits. Another week. Then I can run the test.

Ball valves are not leaking.
End-caps are not leaking.
That leaves the table strips. . . If I have to pull them off, they might as well stay off and I can part out the vacuum system.

Well, Disappointing results. I didn't have a full sheet so I used 4 1/4 sheets an d overlapped the seams with three more 1/4 sheets.
I checked the gauge and it was pulling 5 Hg; About a 50%...

Yeah, I will see how much I can get done Saturday.

I asked the rep from the company that supplies various vacuum applications for different industries, and supplied me with parts for my blower...

Here is what I got so far:

1.
All valves closed.
All zone holes plugged.
Blower only; 9.5-10 Hg

2.
All valves open.
All zone hole plugs removed.

Open the box on the blower and check the hot leg? I will most likely have to disconnect and strip the wire some more, as the legs are barely short enough to make the internal connections.

Okay. Makes sense.

Send me a list of tests you want me to do.

Also send me instructions on how you want me to use the clamp meter on the blower.

As soon as everything arrives and gets...

I have been fighting a bad clod and flu for several days, so I am a little confused. I have to put the gauge close to the pump but anything between the valve and pump can't be tested?

In this...

Parts were supposed to arrive today, but Amazon Prime, as usual, is a day late and a dollar short. Supposed to be here Thursday. . . most likely end of the day.

I will try to get the gauge...

Gauge should arrive with the meter tomorrow.

It's a 3 phase blower running through a VFD programmed to ramp up the start for about 5 seconds. The 70 Amp was needed in case we didn't use a soft start. Because of our location, we do use the soft...

That makes sense. Perhaps the leakage is more severe than I thought?

The max amps the blower should draw is 23-26. It's on a 70 AMP breaker.

I use to have a clamp meter but gave it to friend...
