Mobolazer ML-10 DMX schematic?

[Photonbeam]

Anybody have a schematic for the Mobolazer ML-10 DMX board? Manuals? Thanks!

I just acquired a copy of the manual. I'll post it over the next few days.

nice, for reference I have the ML8 and GScan manuals here

I don't have the schematic for the ML-10 but I have traced out the RG-BEAM which is basically an ML-8 G-Beam with an extra diode driver. I put in about 10 hours tracing the schematic and it is 90-95% accurate/complete and should be similiar to the ML-10. At least it will give you some idea of what they were doing.

I have a ML-10 300 and I have traced some of the interlock connections between the Laser Physics Reliant Argon & the mobolazer PCB board, but not the main board itself. I don't have my sketches with me but I will look for them when I get home. The Laser Physics provides 110v through the interlock DB-15 connector to power the mobolazer motherboard. The mobolazer pcb has an 110v to 5v(?) step down xfmr to power the mobo board. The mobolazer motherboard provides an interlock loop back to the Laser Physics, to enable the argon laser. I also have most of the I/O pins inside the laser physics traced & labelled that I can post later.

I traced the ml-10 interlock b/c I was having trouble with mine never shutting off the argon. When I turn off the interlock key switch, the beam would go off. The fan would cool the tube and then shut off the fan. Minutes later, the tube would still be running at low power, heat up and restart the fan. Endless loop! For a temporary work around, I added a separate 110v line cord to the fan. I shut off the keyswitch, wait for the fan to cool/shutoff and then power down the argon mains switch before it starts up again. I let the fan run another minute then unplug it too. I messed with troubleshooting it for a few days and it has gotten pushed aside for now by other things like work.

The ml-8 RG-Beam schematic is attached as a jpeg. PM me if you would like me to email you a pdf of it. Hope this helps.

What is wrong with your ml-10? Is the argon laser acting up, or is the mobolazer beam table? I have copied the G-beam, rg-beam and r-beam ROM contents with my eprom burner, and one day I will copy the ml-10 ROM to safeguard the data for the future. Eventually when I get time I intend to disassemble the ROM contents of the different MOBOs to try to print a source code listing for the different firmware. Some of the DMX channels (13-16) on the RG Beam do not have output and I would like to update the firmware to enable the use of channels 9-16 for other DMX chores. Dreams!

Hey Eric that's some pretty good work you have done there. My hats off to you for your efforts in keeping these Mobolazers going.
I recently acquired two ML-10's. One of them was sold to me with the argon laser not working. We traced the issue down to it possibly being
a transformer on the main Laserphysics board. After some cleaning and reassembly the laser fired up. I did disconnect and check all the cables from the interlock.
I also made sure they where all making the proper contact. The second one I just received today. Ebay purchase. It arrived well packaged and it worked fine. I spent a few hours cleaning it and aligning the beam mirrors etc. The only issue I am having is with the G-Scan. It appears that the keypad does'nt appear to be working. I'm not getting any indication that is is powered up. No signal. Hopefully I'll be able to track down a used one.

Again great work.

Thanks for the good comments. You might want to call Laser Works in California. They designed the G-Scan for Mobolazer. A few years ago I bought their G-Soft software and cable with db-9 plug to rj-11 plug. I think it was around $150 and replaces the smartpad controller. I use it with an old pentium 1 laptop with 9 pin serial port. The software isn't great but it is 100 times better than using my smartpad keypad.

Thanks Eric. I sent them an email. I did manage to open up the driver portion today. I noticed that one of the Led's on board was not on and had a lower voltage coming in. I'll call them Monday. There website says they are in Arizona now.

Beep Beep!

I got a Mobolazer ML-10 with a burned up 300mW Laser Physics argon on a trade many years ago. I discarded the argon laser carcass and installed my 2.7W Melles-Griot yag. I paid around $15K for the MG yag and back then there wasn't fast analog modulation. Just TTL to about 1KHz. It's been a great little projector but I was getting tired of green only and decided to add red and blue. So I recently built a RB module with two P73 637nm and two 9mm 445nm diodes, each pair combined with waveplates and pbs cubes, corrected by anamorphic prism pairs and added with dichroics. I'm getting 1.5W of red and 2.5W of blue. I was interested in the ML-10 schematic because the DMX output was around 2-12V (each ch a little different) and I needed 0-5V control for the RB module. The ML-10 drivers have gain pots but no zero offset. I made a small op-amp circuit with gain and offset to install in the ML-10 so I could convert two of the channels to 0-5V out. I only wish the MG yag could be modulated as fast as the red and blue diodes so I could do graphics. Maybe a AOM on the green is the answer? I'm happy with the way it turned out with all the new colors. I would trade a Laserscope for another ML-10. ArcDevilz?

I have access to another Mobolazer without turrets. I was think of putting an RGB setup and turning it into a lumia projector.

Photon I'll keep my eyes open if another comes up for sale. I have serial number two ML-10 with an argon and two 650 diodes that where done by Mobolazer.

nice, really nice

care to share your opamp circuit? I was thinking of doing the same thing to my ML-10's but just have not gotten around to it
