FRUSTRATED! Epilog changing home

[Ben Levesque]

....if I ran the job from memory once and it worked fine then I should expect the same results on the second pass.

Right? or am I missing something?

Not necessarily, since all (on my part) was related to a bad drawing that I thought was good in the first place just by the looks of it, so weather or not it was in the laser memory, I was getting intermittently bad alignment in my end results.

Did you use the Corel trace tool to create your drawing ?

I'm just wondering why your running 'two' passes on granite. Granite does not require much power to etch. Real Marble, can benefit from a second pass (gets much whiter) but granite offers no real improvement on multiple passes...Sometimes if you run a photo a little too light, a second light pass may improve it (but your taking a chance)..

I agree with Bill on the granite one pass should be enough. As for the shifting problem have had the same thing happen and changing the cable has fixed it both times. That cable gets lots of use and bending especially if your doing a big piece and running the head full travel. It's easy to have a wire break inside the cable. I've replaced 3 on mine in 5 years first one went in like 6 months and the others have lasted . Replaced the last one about a year ago. And at 15 bucks each might just start keeping one handy and replace every year.
All I can say about Epilog service is it's top notch and have had me up and running over night even when I broke on a Friday afternoon on a holiday weekend , had the part here Saturday morning from a Dealer in LA.
They hand carried the part to UPS after hours and shipped it overnight at no extra charge.

Flipping the cable seems to have worked so far... The new one is suppossed to be here today... I guess the odd part in all of this is why it went out in just 2 months, is this the service exception to the rule... I just got the odd man out but most go for a year before they need a new one? I dunno, I can tell you that I appreciate the advice from folks here and the support of Epilog walking me through this though...

Bad cables right off of the shelf happen, though it should be exceedingly rare. They can be damaged during installation, but you would have to be kind of harsh on it. Poor QC of the materials going into the cable or construction during manufacture can happen, and this would be the most likely cause. I will say, though, an average lifetime of 1 year for a cable to break means either the cable QC is poor or the design of the cable/connection should be looked at again, even in a production environment... semiconductor manufacturers use flex cables for their test/assembly equipment (which moves a lot like the laser carriage), and they would be pretty ticked off if the equipment had a MTBF of 1 year due to something like a cable (other issues are a more likely failure mode).

Hi,

Have your metal rod on top of x axis encoder, which holds to and fro the air hose got any touch with x bare board, if so, would make some problem
