Re: Gweike power supply connections

I found it on Craigslist for about $500. A guy had it in a shed in his backyard for a few years and rats and/or squirrels ate all of the wiring and belts. It was filled with leaves, shells from nuts, acorns, and rat turds. Mirrors were all oxidized. The tube in it didn't work, but had a spare new Re...

Re: Gweike power supply connections

Hmmm, just found a manual online for the Leetro MPC6515 DSP that was in the laser and it shows an analog output for the laser so my thinking is that I am going to have to replace the power supply with one that has PWM input unless someone knows different.

red dot pointer

Is the red dot pointer normally connected to a manual switch to turn it on and off, left on all the time, or controlled by the DSP somehow?

Gweike power supply connections

I am retrofitting a Gweike laser with a Lightobject DSP. The power supply has no marking as to what pin does what on the connector. I know the connector on the left is the AC input. Can anyone tell me what the connections on the right side connector are and what they should connect to on the DSP end...

Re: Powering up old tube

Thanks Marco. I just ordered all new optics from you today. Got the DSP about a year ago, but other projects have gotten in the way and just getting back to it now. Hopefully I won't be buying a new tube and/or power supply to go with the rest. Working on a Gweiki that I got a great deal on Craigsli...

Powering up old tube

I have a laser with a 100W Reci tube that has probably not been powered on in 5 years or more. Other than cleaning the optics and making sure that I have good water flow and purge the air is there anything I should know before powering up the tube. Does it need to be run at low power for any amount ...

445nm diode

Looks like you can get 7W 445nm laser diode modules fairly cheaply from China now. Claim to be able to engrave stainless steel. Not sure about aluminum. Can anyone give any comments about what power and speeds are needed for engraving stainless or cutting very thin stainless with this wavelength? Wi...

rust cleaning laser

Found this cool video of a rust cleaning laser. Not sure if this is CO2 or not, but sure looks like some experimenting with CO2 should be tried. If anyone tests this out before I do let us know what the results are. http://www.electronicproducts.com/Optoelectronics/Lasers/Oddly_satisfying_video_of_t...

LO R5 uninstall

I made the mistake of installing the LO R5 plugin for AutoCad on my work computer to check the software before I bought the new DSP for my home computer. It is on Windows 7 and AutoCad 2012. After uninstalling the software I was getting errors on AutoCad about VBA not being installed and messages ab...

Re: Max Power on engraving vs. cutting? (AWC/LO-X//Lasercad)

You won't get an accurate power reading when engraving because the laser is turning on and off. The max power you use when cutting is the max you should use engraving, but it will read lower on the meter.

Re: Weike laser upgrades

Marco, having a hard time getting you on the phone so will ask here. Looks like I will need to replace the mirrors. The machine has 25mm mirrors now. Are they big enough with an 80W Reci tube and a beam expander or should I get new mounts and larger mirrors? If so, what size. The machine also has a ...

Which DSP to buy

I am going to buy a new DSP for my LC6090 laser. I have the AWC608 on my K40 machine with LaserCad and I have two major problems with it. Wondering if I use the R5 controller on the new laser if I will have the same problem. I do all of my drawings in AutoCad. The first issue I have with Lasercad is...
