The latest version, Version 1.0.0.3 is rearranging the Cuts/Layers all by itself. I put them in the order that I want them to be, save the file and close it down. On reopening the file the Cuts/Layers table has been rearranged. It must be a bug that has been unintentionally introduced in the latest version because I have used a number of previous versions where it worked as you would expect, i.e. being in the same order as you saved them in. Can anyone advise? Thanks.
Save it like this:
I second what RalphU found. I typically don’t rename my layers and all of those files that I’m in today reopened just fine. When I tested with the layer renamed it opened wonky.
Two of us here haven’t been able to reproduce this. Can one of you confirm the steps you took, and which layer types (image, line, fill, etc) you used?
Hi all, As you can see from the first screenshot I have a picture as an Image, followed by another picture as an Image, followed by text as Offset Fill, followed by the outline (a circle as the cutting out line) as Line and finally T2 as a Tool (which is simply a box that I use as a representation of the piece of plywood that I am burning). I have double and triple checked that what I reported is actually happening, and it is. I have also created a second “dummy” file with the same features as my actual (real) file with 2 pictures, text, an outline and lastly a T2 tool. I save it in that order. I close the file and then reopen it, and it behaves exactly like my actual (real) file. The top row becomes the bottom row and the bottom row becomes the top row on reopening the file. That is they are swapped with one another. Thank you to you all for your quick responses. Martin
As a quick workaround in the mean time it seems that if you put a vector later at the top of the stack it retains order, even if the output is turned off.
This is fixed and will be released shortly, assuming it tests fine.
This was a series of unfortunate events:
At least one of the online test file generators allows you to export more than our built-in number of layers, and ended up overwriting the slots for tool layers at the end.
Users with those overwritten tool layers would have the broken tool layers persisting because LightBurn keeps your last settings for each layer, and we assume that nothing is breaking our settings but us.
Adam wrote code to fix the busted tool layers, and ignore all but the desired settings on them, but missed the setting for where it goes in the cut list
That’s great Oz, well done on finding the issue so fast! I am a big fan of Lightburn, it’s an awesome piece of software with more features than any individual user will ever use. Keep up the good work, Martin
This is way off-topic, but if you’re using a CO2 Laser and those settings are what you actually use, you may need to look at them a bit closer. Running a CO2 Laser above 50% power is not really a good idea. In the same way a car engine burns up far more full at higher speeds, a laser’s life expectancy will be far less at the power settings you’re using.
John - That’s very misleading and somewhat untrue. If you run your CO2 laser at or below the manufacturer’s suggested power rating you will get the life expectancy of the tube. For instance, a Reci W1 75W tube should be run at or below 22mA which will equate to roughly the advertised rating (my tube’s max output was measured by Reci to be 82W). Above 22mA and you will shorten the tube’s lifespan. CO2 tubes are consumables and should be treated as such. Not using a tube to its rated power when needed is a waste of money. I’m not going to spend 4X dollars to buy a 150W tube just so I can cut @ 75W; the 150W will NOT last 4X longer doing that since all glass CO2 laser tubes degrade over time regardless of whether they are used or not. Buy the size you need and run it as intended and replace it when it is worn out.
The key is configuring your machine correctly and adding a milliamp meter if you don’t have one. Many laser power supplies will have a potentiometer on them to allow adjusting the max power output, you should adjust it so that it won’t go above the recommend mA rating of your tube. That way, 100% power in LBRN layer equates to the recommend max mA rating and you don’t have to worry about going over it. If you can’t adjust the PSU, you should figure out what power % per layer will hit the max recommended mA and stay at or below that %.
Any file saved in 1.0.03 with tool layers will need to be loaded and re-saved in 1.0.04 to get the layer order to stick. If you have saved in 1.0.04 and it’s still reordering on you, let me know, and show pics of the save/load layer order so we can try to reproduce it.
Seems like it is ok now , cannot reproduce it even though it was doing it on 1.0.0.4 ?
the other thing that was happening was turning the output off for the black layer
but seems ok now as well
