So what the heck is going on with the 10W laser?? I havent used it as i put the machine away for the winter as its a summer garage thing.
I updated everything and now when I go to line engrave its WAY to light and its like the image is bleeding like it was ink.
Before whatever version i updated from it was almost perfect and now everything is blurry.
Setting were 0.08 at 30% power with 5000 jog and 3000 work speed
It would be nice to get it back to normal so it doesnt look like garbage. Ive spent about 4 hours total messing with setting and the images dont get a better quality like they once were
Playing with the dot compensation worked to a point. Still have some fuzz along the edges. It also doesnt burn everything evenly any more as seen in the picture below. Now thats before playing with the dot settings from the other day but you can see the lines coming out of the what is to be a globe are way lighter then the globe itself.
It would be nice if there was just a choice if you want to play with those setting or not.
After hours, and i mean HOURS of testing settings, it looks like Luban gone done and dicked me with forcing the machine to slow down.
Normally setting were 5000 jog 3000 work at 0.08 and my images turned out amazing. Now in order to achieve the same level of quality i have to kick the work speed down to 1500.
Whoever programs this, gosh change it back to whatever you had it at before, or at least have an option for old settings.
You bet, just redid it just in case. Same outcome, im surprised honestly that no one else has complained about this already, i cannot possibly be the only person to be having issues.
For the time being, the project that im doing will just need to take longer. I appreciate everyones suggestions and help.
Iām still on Luban 4.4, and lord only knows what firmware, because of threads like this.
I have a lot of (10W) laser projects saved and donāt want to have to go redo them from scratch because of the new settings, even though on the face of it, they sound like positive capability additions.
Im sure some are really good features, also some people use their machines for work and have the ability to learn and figure it out in way less time then I do. Hence popping on here. Some really good suggestions, and i think i want to try Lightburn too, just nothing fixed it short of slowing the machine down by half as of yet.
Hindsight is always 20/20 so i wouldnt personally have updated if i wouldve known. But at some point i wouldve been forced to and would just be pissed off later. Maybe if you have a second computer that would be were you can learn on but still use the other for getting stuff done.
Iām late to the party, but I experienced similar reduced intensity with the laser. It seems to stem from when they added support for the 20/40W lasers and switched to inline mode instead of using m3 in the gcode.
For the life of me I canāt figure out why it reduced the intensity as the fixed value was changed to a variable, but number is the same and I just donāt understand it well enough to dig deeper.
If you want your files to run how it used to burn, what I did was keep Luban 4.8.2 (last version of software before changed to using inline mode in the g code) you can make the file on a newer version, toss it over to the old version to generate the code and voila, stronger burn power again like it used to be. This works fine with most current firmware.
Hey @Tandar21. The fuzzyness you show on you lettering in fill mode just appeared on my engravings as well right after I installed the Bracing Kit! This looks like a scan offset issue due to backlash. Scan Offset | Snapmaker Wiki I got this both in lightburn where I normally work so I tried Luban and got the same thing. Did you ever find a solution.
There is a setting in Luban to adjust the the scan offset but Iām not sure about lightburn.
Well, there are two issues with that āweāre not going to tell you too muchā wiki: 1. It says itās to help with ālarge mechanical backlashā - Iād want to deal with the backlash first. 2. It says to input a percentage" but the box is clearly marked with mm.
Logically speaking, though Iāve never tried this, there is a method to determine if itās backlash or laser delay.
If itās backlash then the total width of a lasered feature will be wider than intended. If itās laser delay then the total width should be pretty much as intended.
Try lasering a strip that is (eg) 2mm wide. If the lasered resultās total width is wider than 2mm then the burning when it is moving Y+ is happening at a different position to when it is moving Y-. This is backlash.
If the lasered strip is the correct total width it means it is correctly starting and stopping in both directions at the correct positions, but the laser is taking a moment to come on or light up fully and therefore doesnāt start burning at the correct position. Slowing down the whole operation gives the laser more time to light up and this problem will be become less obvious. The āScan Offsetā setting is there to compensate for this design fault.
