Mein Problem liegt darin das beim Gravieren eines Bildes, der Laser an jedem punkt lagsamer wird und dann wieder beschleunigt.
Ich hätte aber lieber das der Laser einmal durch läuft und den Laser nur an den stellen ein und aus schaltet.
Ist es möglich das es daran liegt das ich den sterbefehl
M03/M05 Benutze?
Ist das normal so oder habe ich eine Einstellung falsch getroffen.
vielen dank schon mal, hoffe das Problem wird gelöst.
I have a question about the software.
My problem is that when engraving an image, the laser slows down at every point and then speeds up again.
But I would prefer that the laser runs through once and only switches the laser on and off at the points.
Is this normal or have I made a wrong setting?
Thank you very much, hope the problem will be solved.
I was hoping Marlin used the same ‘machine settings’ query tool.
There is a laser mode that doesn’t pause or stop the way a milling machine spindle needs to pause. Looking at Marlin quickly it seems that it’s a ‘Build-time’ configuration change but i know nothing about Marlin. I’ll move this to the Marlin group and i’ll dig in a little bit to see what i can find out.
Engraving an image would normally have consistent speed across the entire line with only the laser head turning on and off as necessary.
I recall something about Marlin potentially behaving this way.
Try using Inline mode if you are able. It allows for variable power and is similar to GRLB laser mode. I recall someone saying this resulted in smoother motion on Marlin controllers.
Inline only works in relatively newer versions of Marlin. I believe 2.0.4+ but could be wrong. I don’t know if it’s compiled by default or if it needs to be configured but might be worthwhile to see if there’s an update available that you can install.
Ich habe die neueste Version von Knutwurst drauf gespielt (Marlin basierend)
Habe aber auch die neueste Variante von lightburn auf dem Laptop.
Ich steuere den Laser direkt über lightburn an.
I played the latest version of Knutwurst on it (Marlin based)
But I also have the latest version of lightburn on the laptop.
I control the laser directly via lightburn.
The Mega Pro BMP Laser feature is not (yet) supported. Use the M3 Spindle/Laser feature instead.
Going to the link shows this:
Notes
S is interpeted as the configured value range: PWM (default), Percentage, or RPM. (See CUTTER_POWER_UNIT)
M3 and M4 aren’t needed with LASER_POWER_INLINE and LASER_MOVE_POWER enabled. Power is set directly in G1…G5
It’s not clear if or how LASER_POWER_INLINE and LASER_MOVE_POWER are to be enabled (I assume at compile time) but seems you can still use it if by setting I with the M3 command.
I just checked the g-code output of LightBurn using Marlin with Inline and it’s not clear to me that it’s valid syntax based on the documentation. However, it’s well known that the documentation for Marlin isn’t always current. LightBurn g-code shows I inline with G commands.
You may want to try modifying the g-code to include an M3 with I and see if that behaves differently.
Try the same code but without the ‘I’ in it. Does the motion change? If so, I think that means inline is working. There may just be a syntax issue with the code generation.
