Good morning all, new forum user here
A friend donated a SH-G475 laser engraver/cutter to me (and is now out of the USA for a long period of time working). I am trying to identify it as some google search said it was an OMTECH, but on their site no info is available for it. Trying to get any information on how to set it up, replacement parts and software to use with it. No other markings are available on the equipment other then the product identification tag.
Before anyone posts the dangers of a class IV system, I am a very experienced user/setup/repair of class IV Argon systems, and though the CO2 is infrared, I fully understand the remifications…
Any help with my equipment is greatly appreciated
Welcome to the site Alex. Hope you enjoy it.
I don’t really know what you want. Does it work at all?
There is no one that will walk you through setting one of these up, they are relatively simple in operation. If you have specific questions, sure we can help.
So at what point are you having difficulties?
Is it this one?
You should be able to post a photo of problem machines or areas.
Hello Jack and thank for your reply.
My device has no OMTECH labelling anywhere on the cabinet at all. My friend didn’t provide me with any documentation on it at all so other then using my knowledge and ‘poke’ so to speak at it don’t ave any Mfg docs at all.
Looking at the device it looks very similar to the photo posted except the missing front logo.
Virtually all of these are assembled by some manufacturer and the vendor plasters it with their logo. Most use similar parts many times from known vendors.
Are you using Lightburn? Main thing to know is the controller. So crack the electronics door open an take a photo of it or it may be identified on the label.
If the machine console looks like that in the photo then it’s likely a Ruida. Ruida machines can have different consoles, but this is a common one.
Don’t pulse or use the laser part of the machine without a flowing coolant.
Can you answer these?
- are you using Lightburn in it’s trial period
- does it power up properly
- does it have a chiller
- does it lase when pulsed
Thanks again for all the repliws and hand holding…going at this slow
Ok, when you get a chiller or circulation pump for diagnosis, then ask whatever you need to ask.
When these lase, there is literally lightning in a bottle, so you have to ensure coolant flow to protect the tube.
I purchased a 5000 series chiller, as I live in the SW part of the USA, so it’s pretty dry and pretty hot. The 3000 series chiller is just a radiator with a fan blowing across it, not really functional in most hobby laser applications.
When you get it operational, I’d suggest the free trial, but it’s the best laser software available. I’d suggest, if possible, you connect the Ruida to your lan and access it via the Ethernet connection. Much more dependable and easier than USB.
Good luck
Awesome thanks. I live in the southwest part of USA (NC) so a good chiller on 90+ Fahrenheit days …
My holography Argon lasers (50-100W) I’m very familiar with used a very parge chiller with de-ionized water as the coolant
Thanks again for the intro, will look at the Ruida products and see if I can get some docs from there..
Thanks
Most of us here have the documents for most of the common Ruida controllers. If you can figure out what you have, maybe we can up the pace for you.
This is my Ruida 6442g and it’s console.
