We all interpret what someone is saying in different ways. I don't think Marco is trying to pick his customers. I think what he is saying (now of course I could be seeing this incorrectly) is that...

Hi, I am not familiar with the controls on the M300, but I can tell you that I am very pleased with the AWC608 controller that I installed in my old ULD25PS. Being happy with that, I recently...

Hi,
This is copied from my similar response earlier in this thread:

I ran my ULS25PS with DSP Control and the original RF Laser for a while. The two connections of the coax (shield and center...

Hi Emily,

Synrad lasers are a good quality laser and worth rebuilding if you decide to do that.

Thanks. Chris...

Hi,
I had a very similar issue (almost identical actually) with my machine a few years ago and it ended up being the Synrad laser that was bad. My laser was about 15 years old at the time, so it...

Hi Adrian,
I see, the homing you are describing makes sense to me now. I ran into this same problem when I upgraded to DSP control. I am not sure exactly why, as this was a couple years ago for...

Hi Adrian,

I am not familiar with the controller you have, so I am not sure that I understand the homing problem you are having.

Regarding my Y motor, I think this is the original Y motor that...

Hi Adrian,

That is awesome that you have found a ULS25PS and are planning to bring it back to life. It is an older machine, but a real workhorse, and built heavy duty. I will try to answer your...

I ran into this exact situation on my ULS25PS.

Your optical limit sensors have an emitter and a receiver. Two wires for the emitter, two for the receiver. The receiver is an open collector...

To confirm my most recent post, connect the coax to PWM and Ground from the DSP Control. PWM to the center conductor of the coax, and Ground to the shield of the coax. That might be obvious, but...

Hi,
I have a ULS25PS that I converted to AWC608 DSP control. I recently converted to a glass tube laser, but prior to that I ran the Synrad RF laser controlled with the DSP controls. The two...

Hi Nicholas, I ran my ULS25PS with DSP Control and the original RF Laser for a while. The two connections of the coax (shield and center conductor) were wired to the Laser output on my DSP control...

Hi Greolt,

What features and benefits encouraged you to upgrade from the AWC608 to the AWC708? Or, if this has been discussed in another thread, can you point me to that?

Thanks. Chris...

In my case with my ULS25PS, I chose not to fix the tube, for several reasons. But, several decisions hinge upon one another.

The old ULS electronic controls do not have the signal or power supply...

My ULS25PS was recently performing similar to what you are experiencing. It was manufactured in 1995, and was running on the original RF laser. Just the fact that it was still engraving after...

Hi,
Is there more to that model number, such as ULS-25A, or ULS-25PS?
Thanks. Chris...

Hi,

I just uploaded a few photos. It is a 2 position socket in which a plug will override the system when the lid is open. I have never had the plug for it, and managed to do any adjustments...

Hi,

PWM should go to the analog pin on the Laser PS input. This input on the PS is expecting analog 0 to 5VDC and determines the power level output to the laser tube based on the incoming voltage...

Hi,

Looks like you are making good progress! Regarding that safety interlock connector, I am sorry I don't have a photo of it right now, or a part number, but it is a round...

By the way, are you planning to use the existing ULS25PS power supply with a new glass tube Laser? Not sure if it is capable of that. If you get that to work, I will be curious of what you did....

Hi,
I enjoyed your you tube videos, and I am anxious to see more of your project. I too have a ULS25PS that I have had for a couple years. Surprisingly, my Synrad laser was still working, but just...
