Danny and I were on Tarkin last night until quite late. I did several production runs under his observation. There’s no reason I see for the red tag. The offset between start and end of a closed curve is minimal but has been there in the past — while there may be something Danny can do to make it smaller, I don’t see any barriers to general use, definitely no reason to lock out the machine.
I recommend removing the lockout. Post a notice on the machine / on Skedda about the offset to make users aware.
Robert is running tests today and will remove the red tag if all is well.
Up until 8PM last night, Tarkin was doing this ( wiggly lines, non completed cut outs) on any near 45 degree angle. Danny discovered the fix to the issue and was testing it out when I left (shortly before you arrived)
I’m glad you were not seeing it. If you can shed some light on your materials and settings, that would be greatly appreciated.
I will post some details in the red tag post shortly and lift the red tag in favor of yellow.
I ran this test on 1/4-in. Baltic Birch, interior grade. From fine lumber, this is from the 5 ft by 5 ft stack.
I was seeing this while cutting at various speeds from 34 up to 100.
I believe Nick was using the 1/8 in Baltic Birch. Also from fine lumber, interior grade.
I also noticed a couple of cutouts not lining up exactly on the start and end. This was happening on various types of plywood, interior and exterior grade, high-speed settings and low speed settings, and the boards were all locked down pretty securely. It was very minor but certainly noticeable.
The not lining up begin/end of cuts was there. That’s been there at various times over the years to varying degrees.
I was cutting mostly at 60 or 70 speed also on Baltic birch but with paper glued to the surface and paint on the other side. My tokens came out beautiful clean edges. No straight lines — all curves. Maybe that’s the key?
Yeah, pure curves don’t seem to be affected by the “wiggle” problem. Likewise straight lines on a single axis are fine.
It’s quite odd- it shows up only when the head is moving at certain angles in relation to the gantry itself (meaning if the head is moving at a 45ish degree angle and straight the wiggle happens). If you rotate the file being cut, the problem lines do not remain the same and the new “wiggly” lines will be whichever are 45 degrees or so from the X axis.
@dannym This may be something that starts to occur during a long running print. For the angel file I was running (should still be accessible), it started happening after the 15-20 minute mark I think. At least it was more noticeable on the final 3rd of the run. The first part of the design looked pretty good.
@NickE what about yours? Do you think it has happening the entire time and more related to the angles you’re describing? Or do you think it started doing that after a certain period of time.
Without seeing what the file looks like in lightburn, I see a few spots off hand that appear to match what Nick and I were seeing. I circled them in blue.
The dime for reference is great as it shows how detailed we are getting here. For many folks, this won’t be an issue and is why we are moving to yellow Tag. However, and assuming the lines are more crisp in light burn, I would expect this should be able to cut that pattern with "higher resolutions"or less jank.
