I have installed two X-Move and two X-Scan LED fixtures at a local dance club with DMX control. I wanted to use the X-Move to chase gobo effects on the reflective walls of the club as well as spot effects on the floor. I noticed that the X-Move units do not accuractly track their pan/tilt DMX programmed positions over time. They become slowly out of alignment after using DMX controlled pan/tilt movements and can't be re-aligned without cycling power. For example, after about 10 minutes of movement, both units are not able to return to DMX pan/tilt positions well enough to point to the center of a wall! The two X-Scan units track perfectly on the same DMX controller the entire night of use (as well as the 24 other fixtures used in the club). Even running the built in movements as stand alone (no DMX) desmonstrated both of the X-Move fixtures drifting differently in extreme pan/tilt positions after a few movement cycles. My question is, are the X-Move fixtures simply not designed to be DMX pan/tilt accurate? If they are not accurate, is there a way to reset their home position via DMX without cycling power? Otherwise, I would not recommend them for a DMX show requiring any accuracy (even to point them to a mirror ball). Thanks..

Well Also you got to remember these are DJ lights for kinda being thrown around the room not necessarily for spotting people or objects. Also these units i believe feature only 8 bit pan and tilt channels so you wont get much of a precise pin point accuracy as you would with a 16 bit pan and tilt fixture. but i am having a product specialist check this out and ill let you know.
Sincerely,
I would somewhat agree that the 8 bit pan and tilt will have less accuracy than a 16-bit, but even so, it is the drift issues that he mentioned that I find worrisome.

The good thing is that a power cycle resets it.

I would think that 8 bit vs 16 bit would also be indicative of better stepper motors. Doesn't typically 16-bit fixtures have a "fine" control for pan and/or title you really let you dial it in?

Even so, with better stepper motors, 8-bit performance can be really good. I would think the issue would be when fine tuning movements that you don't get the same degree of control.

I would think that "If I set the fixtures to point here" and program a spot on the wall and save it(via MyDMX or a controller, not important for this discussion which method is used), I get the impression from his description that after 10 minutes of other stuff, hitting that "spot" with the program isn't happening right.

Definately sounds more of a specialist type issue.
Yea dont worry i get the same issue with all of mine as well.....i dont think that when they designed them they didnt intend for them to be percise. i havent taken one apart yet to see if there is bump stops which more then likely there is, but in the end they're more for just effect then to be percise but i feel ur pain....bein able to have multiple of them hit a mirror ball all at once and havin 2 or 3 of them not even being close throughs the whole look off. Maybe with the next version or x-move 2 they will improve upon this.
Thank you all for responding to my question. I will move the two X-MOVE fixtures apart and use 'random' DMX and/or build-in fixture movement patterns instead. This way their drifting is not noticeable. I can use the X-SCAN to point to the disco ball and walls of the club until I can find a more accurate moving head. I would like to request that ADJ consider adding a DMX command for placing the fixtures in/out of the sound-activated stand alone mode. Otherwise, I need to always program DMX pan/tilt or use the programmed patterns which can get a little repetitive. If you would like a you-tube video of the drifting effect, let me know and i'll post. Would the ADJ moving head laser have the same issue?
Unfortunately the X-Move LED will never be an accurate light. It has no “auto-correction” feature like most high end intelligent lights. I bought six from PSSL and returned them all. They are bright and light but if they can’t hit a position then why call them an intelligent light? The X-Scans work fine and have the same features. Not as cool as the moving heads but at least they’ll keep their positions. I use Martin’s Light-Jockey to control my lighting system and I have over 18 years of experience programming DMX. When you buy a moving head fixture make sure it always has a “feedback” or “auto-positing” feature. AMDJ and elation have a few fixtures with this feature as do most manufactures. Good Luck!
Please define "auto-correction".

I think what all lights need are a reference to ZERO and be able to work accurately in reference to the zero position relative to the total range of movement.

My Chauvet Q-Spot 150's sure ain't a "high end intel", but I'd say are right around the intro/bottom run of moving lights. Not saying junky, but rather good starter movers and good bang for the buck, same as ADJ's equivalent. Accurate? Well, works enough for me. I ran the lights in my random/chaotic scene for 15 minutes during a show break, then punched in my only "position specific scene", and it hit the mark right on.

Maybe ADJ just needs to re-engineer teh X-Move LED's to be a bit more robust and accurate? I do agree that there's no point in having a moving head if they can't keep their positions, as it totally defeats the purpose of programmable and controllable fixtures.

This could also be that marketting targetted a specific kind of user/audience for these, but then as usual, there's going to be guys, ESPECIALLY those like yourself, who are going to see other applications for such fixtures. It could be once outside the target audience, then limitations or oversights of the fixtures become exposed.

If I go with a moving head LED, I do need it to be relatively accurate.
