I noticed today that Tarkin’s power output seems a bit reduced. Still very much usable, just not getting quite as reliable through-cuts at my usual speeds. My guess is a partially fouled lens or maybe misalignment (but FWIW focus on the surface of my material seemed fairly good).
I did a basic check this morning and saw no significant prob. I did start by playing with the breakers and Laser6 might have been tripped, but I wasn’t being really meticulous and reset it before being sure
Hmm, hit another issue last night that might be related: I think maybe it lost half its power in the middle of a ~25 minute job — i.e. maybe a breaker popped again mid-run?
End result shown here (it was doing a fill operation from the bottom up):
I noticed that the sound of the machine got quieter about 30% into the job, but since it did keep running the fill operation and I wanted to see the overall composition, I let it finish. By the time it actually did finish, my plans for the rest of the evening had changed so I had to run. I didn’t find time to do much troubleshooting, unfortunately. I glanced very briefly at the breaker panel in the MPR, but LASER 5 and LASER 6 didn’t look visibly popped to me. Are those the correct ones to check?
FYI @JimmiD tagging you since I see you have the machine booked today on Skedda. TL;DR is that it seems generally functional but possibly having power stability issues.
Yesterday it was stable, but definitely reduced. It was back on the 14th that I saw it lose power in the middle of the job. I hadn’t personally used it in between, so I have no idea if this issue has been variable in between.
FWIW, also checked last night for cone warming in case that got bumped/deflected, but it was still basically room-temp after a couple minutes of doing a fill raster. (And to be clear: definitely did not bump the cone on the 14th, either. The job was very simple, with constant clearance across the piece as shown.)
While I didn’t note exact temps, I did glance at the chiller display and I distinctly remember thinking “that looks low” (i.e. not at all in overheating territory, AFAIK).
FWIW, tonight it seems to be doing sliiiightly better, but still well-below my usual expectations: to cut 1/8" baltic reliably, I still ended up slowing down to 25mm/s (it could mostly cut at 40mm/s, but not reliably all the way). All other layer settings are default, with max power set to 100%.
Chiller consistently reading sub-18°C, which is the chiller’s setpoint. (Right at the moment, it is reading 17.7°C).
Focus is clean, and I just checked the cone for heat after ~15 minutes of rastering – it feels normal.
Thanks. I should have just enough time to finish my project this afternoon at current power levels, but very much looking forward to full power output again.
