Isn't that 2 issues?
1. Temperature
2. Humidity
(devil)
sorry, couldn't help it...................

See how poor wording can change the meaning or understanding of what is meant. (Never claimed to be a writer, but usually do understand what I write. Usually.)

That's new then. That never made it to my manual.
At least they have it documented now.

Wow what a difference. We have the same Epilog Radius model for about 8 years also.
I have never gone much over 1 year without replacing the x axis motor bearings and belts at an annual cost of around $600.
It has taken us to the party overall for years so I am not complaining, but expect more from our 2 month old Xenetech. It hasn't failed to fire so far at the start.
The Epilog rarely doesn't fire right away. A few months ago it did it a few times but wasn't even the first job of the day.
I think it has a sophiscated sensing mechanism. If you don't have any extras, have a customer watching, knows in advance that you will remove the item before checking or complain about Epilog it will be much more likely to not fire right away.

I'll clear the air on this (with no corporate authority to do so).
Epilog uses DEOS tubes exclusively. DEOS is a manufacturer of laser tubes(Wave Guide technology). DEOS was a competitor to Coherent and Synrad for a number of years, but Coherent now owns both Synrad & DEOS, which to my knowledge are still "stand alone" facilities).
While DEOS has been an extremely reliable, efficient tube, changes were made approximately a year ago that I can attest made it even more reliable. Since those changes, "infant mortality" has been almost non-existent.
The technical nature of the changes are far above my head, but one of the observable side effects is the Monday morning startup. Every DEOS tube since this change will miss a few strokes on Monday morning. As most are aware, every tube is allowed a touch of "attitude;" that is, some (about 50% is my experience) might miss a few raster strokes after being turned off for even 16 hours. I have not personally experienced any tube that will miss a "beat" if turned off only for a few hours.
It is also my understanding that it is considered normal "warm up" if under 5 seconds. If over 5 seconds then it should be discussed with tech support.
I believe I would be correct in saying that the "infant mortality" issue was the major (if not exclusive) purpose of this/these change(s). So if you have an older DEOS tube that does not exhibit this behavior, you should not be concerned that you do not have the latest, greatest DEOS tube; that is, you are already well beyond that stage.
One other possible disclaimer, maybe I should say Epilog DEOS tubes instead of just DEOS tubes(?). I understand DEOS makes some "OEM" changes/enhancements just for Epilog and then I understand that Epilog then does some unique engineering on the tube/electronics after receiving from DEOS. Many (most?) of the other manufacturers also use at least some of the DEOS tubes. I said all that to say that I do not know if the DEOS changes affect them also; hopefully we'll hear from other users to clarify.
Definitions: [unofficial, non-technical, home-spun terms]
infant mortality: a laser tube dies after only a few months use
Monday morning startup: after being turned off for two or more days

Roy,
WOW and I thought Americans spoke english!!
sorry couldn't resist it, if I could understand it I'd admire it.
All I know is it doesn't work for 5 seconds then it does !!!!!!!!!!!
cheers Clive.

If you'll confirm that it works *all day long* even if turned off for awhile(even several hours) and that you bought your Mini within the last year that will tie together the explanation.

I have an Epilog Legend 32 EX 40 watt. It was purchased from Roy Brewer. The only problem that i've had lately is that i noticed it took a long time to fire as well. Well Peck with Epilog told me make sure that the cover is closed upon turning on the system, because of the tickle. It has to see that all of the safety contacts are cleared before it will turn on. Since i've done this (make sure the lid is closed when turning on for the first time for that day) it works great.
p.s. If after you turn on the machine and with the first 45 seconds to 1 minute you open the lid, this will restart the timer circuit for the tickle. Make sure you turn on the machine and then wait before opening the unit to put any items in.

If that does it for everyone with the problem, you have just provided a very important piece of information.
Thanks.

Roy,
Yes it works every other time during the day, and yes I turn it off and on quite a few times, it was purchased Jan 06.
I did try one other suggestion from the forum and that was to switch the machine on for a few minutes (first time of the day) before using, I tried this and it seemed to fire straight away, I've only had time to try this once so far .
regards Clive
