Thread: My New Hermes/Gravograph LS900 lost its mind...

  1. #1

    My New Hermes/Gravograph LS900 lost its mind...

    Seems I lost the controller last night. The machine had been on all day (typical), about 9pm I'm ready to Cermark some SS plates. I move the head to focus on the plates, then sent it home. After shaking up the Cermark, I proceed to move the lens head to the right, out of my way. The head moved slightly, then stopped. Machine was on but totally dead otherwise. So I flipped off the switch, then back on, and got nothing at all...

    Power switch tested okay. Removed the back, and powered up by plugging the cord. Got a 'tick-tock' click, one from the power supply, one from the controller. The controller made a very faint, high-pitched 'squeal'. The laser tube powered up okay. And a row of transistors(?) surrounded by a heat sink & shroud started getting warm. But nothing else worked, fans, display, nothing.

    So I got in touch with my rep this morning, and he stopped in about 1pm. After a quick look he explained that working on the controller was beyond his pay grade, and that I should plan on sending it in to be tested and price quoted. He called Gravograph customer service, spent about 2 minutes on hold, then got answered. CS said to ship it to them, after they email me the necessary paperwork. We asked if I could upgrade the controller to accept newer firmware and add a USB port for input, the CS rep had to find out, then answered 'yes'. Since it was almost 5pm CS time we were told I might not get the paperwork until tomorrow.

    Gravograph doesn't have the best customer service reputation, at least with who I associate with online, so this will be kind of a real-time test to see how I'm handled. Because funny thing, since this became my full-time job in 1976, I've acquired 11 NH/Gravograph CNC machines, 2 lasers and a vinyl cutter, all but ONE of which is still in service (and it works, it's just in storage)- and in all that time, I've had to deal with NH factory service only 4 times, and 2 of those were warranty work: a free driver upgrade and a belt replacement. The other 2 times were today, and many years ago when the power supply in this same laser went out...

    Kind of hard to complain about customer service when you hardly ever need it! And having a local rep who'll bend over backwards for you, really helps.

    So this problem is officially the worst of 3 'catastrophic' machine issues with 14 New Hermes machines over 42 years. Knock on my head - And this one will hurt the most simply because this is my most-used machine, and it will be down at least a week. How much longer than that will be the focus of this Customer Service test

    some people wonder why I have so many machines, this is one big reason; with my most used machine down, I can still get the work out...

    Good luck! And I love the Gravograph galvo CO2 they offer. If I had the cash and need, I'd love one.

    Ok, so I lied! I was amazed at how fast the work WASN'T getting done without this machine! So much so I bought another laser! (other post )

    The CPU finally found its way back home, works great again! The X-axis sweep sounds totally different. Which now may explain why about 2 months ago it started sounding different. Anyway, the sound of it working at all is a blessing!

    But alas, now I have 2 Gravograph lasers about 11 years apart in age, and I'm having driver issues: The older 900 driver doesn't have the LS100 "IQ" model in its 'will run' list, and the newer 100 driver won't 'drive' the 900; rasters fine but won't vector. And the computer won't load the 2 drivers, it's either-or... so the EZ fix is my trusty XP virtual machine... works like a charm to run the new machine, and the 7 runs the 900 like the old days. My VM will only run Corel, so it'll be no different switching over to the VM than switching between X3 and X4.

    But since computers hate me, another issue popped up that's stumped me, my rep and HIS rep- when connecting to the new laser thru my network on a 'slave' computer, which is easy enough to do, you can send any job to the machine all fine and dandy, but it won't accept the slave computer's machine settings? The settings the machine gets are whatever the last-used settings are on the HOST computer..? This happens whether using USB or parallel connection to the machine, and 3 slave computers do the same thing. No one I've talked to so far has an answer, my best guess is it's a win7 thing, and I'm not going worry about figuring it out. So I've ordered a 2-computer/1-printer USB switch to avoid the network. $12 Amazon.

    I'm already glad to have another laser handy, all 5 have worked lined up, and I only have 2 tool machines idle...biz is good

  4. Hello Kev

    Please forgive me if it is not proper to insert my question here.
    The topic is New Hermes IS 400 rotary machine using Gravostyle. My old computer with a parallel port just died. I have a parallel port dongle. Do I need to search for an old computer or ???
    I picked you since I see that you have had New Hermes experience. I used to live in Atlanta another lifetime ago and I was on a first name basis with tech support at NH. Someone else was paying for the support and I took advantage of their knowledge. Then they change and let go of the really good software people and I was happy for what I had already learned from them. I started having issues with pages coming up in French (Type 3). No one knew what to do.
    I have the gravostyle install software but only win 10 computer with no parallel ports.
    I have a call into NH but no contact yet.
    I hear that Vectric has some software that will drive the IS series (the correct post processor).
    Any help would be appreciated.
    By the way I am retired and volunteer teaching 3D priinting as well as router CNC machining to middle school kids as well as adults.
    I am in California on the coast in Ventura.
    Thanks

    If you have a parallel dongle chance are you need a computer with a parallel port connection. I have the same problem only worse, I have 2 versions of Casmate with parallel dongles, and these dongles MUST be plugged into a DOS operated computer, which means nothing newer than Windows 98 or ME. I have an old HP Pavillion with Win98-SE just so I can use Casmate for vectorizing graphics.

    In your case, I believe your software was designed for XP and newer? If so, then your computer and dongle communicate differently than mine, and you MIGHT get by with a USB-to-Parallel converter cable... cheap and quick to find out, Amazon has several for under $10 with free 1 day Prime shipping, search 'usb to parallel 25 pin' and they'll come right up. They DO work, but whether it'll communicate with the dongle correctly I have no clue..

    If it DOESN'T work, there's still plenty of Win7 computers out there in good shape with parallel ports, local want ads/craigslist will probably be a good source, $75 is typical...
