I need help figuring out some of these problems. I’m trying to make some test grids to figure out proper power and speeds for cutting. I used the Shape Properties to grade the individual lines to match the power setting on the left and set my layers to range between 1-100 power adjusting speeds to match my cut speed for that column. I’m wondering why I don’t have anything show up for 5 and 10 mm/s speeds and why are my lines so wiggly? My belts are very snug and there isn’t any movement the gantry when everything is engaged. Thanks in advance! ![PXL_20220411_001337570.MP](https://forum.lightburnsoftware.com/uploads/default/original/3X/e/5/e5debe2b4fe6aadcac44b7b22eb3fcabafcaaa17.jpeg) [Cut Speed.lbrn2](https://forum.lightburnsoftware.com/uploads/short-url/vl2ugELvGWv5Vcu6vdFW7PxtoLW.lbrn2) (101.8 KB) ---

Just some observations. The wiggles seem to change with speed which it looks like something is vibrating or ringing at a constant frequency I cut this material a lot. Can get it cheap at Depot. Is not consistent from batch to batch because it’s not designed for laser cutting. My technique is to cut a 20mm squares at various speeds and power levels. Make sure it’s in focus as that’s another variable. Look for a clean cut with brownish sides. ---

It doesn’t seem to be affected by the material. I think it’s happening when transitioning from travel moves to cutting. I also did a thickness calibrating tool and it had wobbles right at the beginning of the cut but resolved quickly. ---

If you go at or below the ‘Jumpoff speed’ in the controller you will only get minimum power. I’m guessing that your jump off speed is 10 or 20mm/s. You can change it for each axes. ![Screenshot from 2022-04-10 18-22-32](https://forum.lightburnsoftware.com/uploads/default/original/3X/c/6/c6a07b1344126f467059db9a21d094fc06078a61.png) * * * I ‘load’ a line into the machine, then vary the parameters on the controller until I cut through. I then enter that into the material library of Lightburn… * * * This is a z axes focus jig cut on my China Blue 50 watt… 3mm thick basswood ~ 13mm/s @ 80% 2" lens. ![20220410_182954](https://forum.lightburnsoftware.com/uploads/default/original/3X/4/2/42ac4cd4a9d6495b0b7060a82d2da6e5b1e5f11d.jpeg) No wiggly lines… Good luck 😸 ---

That solved my issue of it not firing at the 5 and 10, but didn’t change the wobbles in my line. Any suggestions for that?? Thanks! ---

It’s more than likely something isn’t snug, like belts, lenses & lens tube… Do a good ‘eyeball’ of all the mechanical to ensure all is snug and tight. Your lens in the lens tube can be loose, that’s what I meant by lenses * * * Never thought the jumpoff speed would correct the wobble… The wobble is in the Y axes, I’d check those first. * * * Was the jumpoff speed 10 or 20? * * * Good luck 😸 ---

Thanks! My jumpoff was actually set to 30 as default. ---

Mine was 20, surprised it was that high… one more thing to stick in your brain… 🤪 Good luck 😸 ---

Just checked my belts, mirrors, lens, tube…all snug. Dunno! ---

That doesn’t look like anything but a mechanical adjustment. Some of these can be subtle. Do you know how to check the Y belts? Sorry, running out of gas, heading for bed… Let’s sleep on it and see if either of us has an epiphany overnight. 😺 ---

I ended up changing my Acc factor, G0 Acc factor, and Speed factor all to 0. I don’t really know how this will affect more practical cuts, but it did the trick! ![Test Solved](https://forum.lightburnsoftware.com/uploads/default/original/3X/d/2/d20743d54fe221e80dead0e8fb350689e728d4b4.jpeg) ---

Looks much better… * * * Those are really thick lines, so I question your focus or some other optical problem. Suggest a ramp test to ensure what your real focus point is. * * * I cut lots of plywood with a 2" lens and have a much smaller kerf 😸 ---
