Lazer motor doesnt rotate


These are belt driven rotating heads. While the 500 series have the most robust belt in all the laser industry, they still break. Likely this is the cause. Or the connector has come off the board, it's odd, but it happens.

Why doesn't my spectra troubleshooting LL 500 receiver read the laser it does not beep or notifies (HL 7000 receiver it was working just fine when all of sudden it stop beeping


Try another receiver. If the laser works with the other receiver, then it is the receiver. There is no repair for these receivers, save for cleaning the contacts and circuit board, if moisture gets is. They have a 3 year replacement warranty.
If another receiver doesn't fair any better, then your laser is either putting out no beam, or not the right beam. The laser diode could have failed, or the diode has become unfocused. If this is the case, bring it to a technician to be fully diagnosed.

The off level light doesn't turn off therefore doesn't level at all,


Your vial and compensator no longer match up. Move the foot screws until you can get your laser to spin, then adjust your leveling vial until it reads level again, using the 3 screws holding the vial inplace.

Laser is level but out of level light blinks and will not spin


Your compensator and leveling vial are no longer aligned. Use your foot screws to find a place where the laser spins, then use the 3 hex head screws on the vial, to adjust it to read level.

Resetting LL500 SPECTRA PRECISION LAZER


If you mean you cant level the laser, there are 3 T15 torx screws that hold the base assy into the laser, accessible through 3 holes in the base plate. Unscrew the three screws and remove the base, and disassemble it, clean all the dirt out and relubricate the base with a heavy silicone lube. Reassemble and it should all move smoothly.

How to calibrate spectra precision ll500 laser


There are two brass screws under the upper most metal plate. They are the calibration adjustment screws. The manual tells you how to do a peg test. If your peg test is out, move the corresponding screw until you reach the calibration point you want.

I need to calibrate rotary laser DW073


Sounds like you figured this out on your own. I calibrate my own DW073 regularly without any fancy gadgets. I use the calibration check procedure in which the unit is placed about midway between fixed objects 100' apart.

These have a front and back and sides, so first you mark where the laser hits facing front to back at your targets. Then turn it 180 deg. relevel and resite. If the difference between the new and old marks is not the same then I turn the adjuster to halve the inconsistency and once that is accomplished, tweek the adjusting screw at the end of the level vial. (Because if you have adjusted more than the tiniest bit, the bubble will no longer display as level. So having established level, or closer to it, the adjustment here is actually to bring the relevant bubble vial back to level rather than assume they are level and adjust the physical beam mechanism (unlike the old physical sight levels where you adjusted the actual optics -- a little more like adjusting a rifle scope). Then you repeat for the side to side vial.

Anyway sounds like you are set so I posted this for anyone who happens to find this thread and is looking to field calibrate their DW073, e.g. don't have time or money to get it done in some shop.

I also wanted to post an add on question. Did you figure out how to adjust the "cone error", i.e. the accuracy of alignment of the twin lasers. They appear to have allen set screws that lock their adjustment, and maybe they are then reaimed by using a slotted screwdriver on the brass ring surrounding the laser. Maybe these are made eccentrically or slightly beveled so turning the laser reaims.

So far, my cone has stayed within the specs of 3/32" at 25' in the manual. But I'm seeing two lines at maybe 150' out. Probably that is close enough for gvmt. work, and I may find the adjusment so sensitive that I can't really get it any closer. But I'd at least be interested to know the method for adjusting the cone error.

Thanks,

Brian
