DSP and Synrad firestar 40 laser tube

Here's the video of my new LS600 cutting some cardboard;

Hermes,

It has been awhile since I have been able to work on my laser. I checked out your video and it looks like you have it all figured out. Here is what I have so far. X-850mm x Y-280mm x Z-150mm.

Machine Front.

Machine Back.

I have every thing wired up and finally got all of the stepper motors working (sort of), but I have a problem changing the um/pulse for the y and z axis. I read the parameters, change the um/pulse using the calculator, hit save, and press reset on the display. No changes are noticed and when I read the parameters again, they change back to what was there before. Much like Glenn from this post viewtopic.php?f=8&p=8899#p8899.

When I go to Engraving acceleration it displays 10,000. When I click Read the acceleration goes to 1000. I change it to 10,000 and save and OK. I open parameters again and it displays 10,000, click Read and it goes to 1000. It doesn't save the 10,000.

The Main board: 7.12.12.26
LCD board: 5.12.02.29

Every other parameter seems to change just fine though. Marco, please help me with this. I updated the controller to 130922v7 just to see if that would help.

I am also not sure what I need to change, but the Z-axis cuts out when moving up if I hold the jog key for too long. Is my acceleration too high or too low? Should I change the micro-stepping setting on the controller ore will this all go away with the correct um/pulse setting (if it would work).

Here is the laser power supply.

Laser power supply.

It provides constant power to the laser and the BNC connectors below are what I have connected to the TTL pins at laser1 and laser2.

Synrad Duo-Lase.

I am hoping that both laser1 and laser2 will fire at the same time when lasing. I have the frequency at 5000 Hz for the "tickle/pre-ignition" signal required all the time while running the laser.

Once I get the motion of all the axes set, then I have to try to align the mirror that I replaced. Not sure what the best way to do that is just yet, but I will figure it out. I hope all of this effort pays off, since the laser has been sitting unused for many years.

I've just posted my order for a AWC608, I believe I can pick it up on my way to ARA later this month, after that I'm gonna start building my 2nd gravograph machine, will keep you posted, as always.

The parts have arrived! I'm gonna get to work on this project ASAP!

Thank you for your attention.
