I am trying to find the max speed settings for my Ender 3 s1 plus. I have the 10w creality laser, and everything works as it should.
I have been setting it between 2500 and 8000 mm/s but i dont think this printer can handle anything that fast.
Thanks for reading and all the help.
Hi Spike
If your machine is not a Co2 or Galvo then you should go to (Edit - Settings - Units and Grids) and change to (mm/min)..Better for diode.
I dont know its upper limit but 8000 is still quite fast. Mine handles 6000mm/Min but running it that fast all the time can bring issues if working with detail…lots of short moves and direction changes.
I usually work around 3000 +/- but my module weighs 800g so steady progress is better than speed.
Somewhere in your controller, there is a maximum speed/axes and a separate acceleration value for each axes.
If you exceed the settings for speed, the controller will limit it to whatever it’s been told is the maximum speed.
While it’s running, it uses the acceleration values within the controller.
There are a number of video on speeding up your machine. In simple terms they keep increasing the acceleration until the motor cannot keep up with moving emf. This makes a terrible noise, but it you don’t run into something, it’s pretty harmless to the machine, but makes uses cringe.
When I got my first CNC3018, I followed the persons advise and got some real speed out of it. Along with the speed, I had to fix it to it’s table or it would walk away. Also had to go over the machine as it would just about beat itself to death and loosen all the parts … In the end I went back to very similar factory values.
Lightburn suggests this… I have completely different view of this.
I think this came about from relatively slow CNC machines being fitted with lasers. But it’s just a guess.
I’d much rather enter 100 than 6000 for the same speed. To me, it’s like saying cars under this horsepower range use km/h and the rest should use m/h. They are the same speed, it just adds confusion to people trying to help and unnecessary emails to clear this up what units they using. Living in the US SW and having had a Canadian Jeep, the speedometer was in km/h, not m/h, I know the issue.
I can absolutely see why there are lots of units. LBT100 recommends 35in/s at about 15% power… that’s ripping right along. How many of you had to break out the calculator to figure what the mm/s speed is?
It’s a recurring problem on this and every other site.
If people would just take a 1/2 second and put the units with their speeds we could solve the majority of the issues without suggestions of using other units.
At least @spike80 advised us of the units, so I see no need to ask him to change from his normal to someone elses idea of what’s right…
I have some pretty slow led lasers, a fast co2 and an even faster galvo… I have all of these set to mm/s. I know what a certain speed looks like when it’s running, at least in mm/s, pretty clueless when using a different unit, much like my Canadian Jeep.
As far as I know, these Chinese machines don’t use Inches internally. Also, many of the newer led lasers with enclosed belts can run nearly 1000mm/s… like to enter 60000 instead… Just doesn’t seem reasonable with keeping up with the current technology.
IMHO, we need to start looking at this stuff in a slightly different view…
Sorry for the outburst

Yeah, caught again by the mm per s/min. I think the best thing to do is actually convert to using the mm/s until the knee-jerking stops.
Correction i am using mm/m. So not super fast. I think i found my answer on the creality site. It said as fast as 10000 mm/m. So ill use this as my “fastest” available setting. Thanks all!!
Your controller has these limits programmed into it. It protects the machine from a user excess speed issue. Kind of like a speed limit.
Have fun.
Is this the 3D printer or the Laser module? Belt drive or screw drive? Google was not much help.
No. The maximum speed is not related to the laser head. The speed is related to the mechanics of the system and the weight of the laser head.
The Ender 3 s1 Plus is rated at 150mm/s (9000mm/min) maximum speed for printing. Printing uses a lightweight head. The laser head will be much heavier. Also, the workpiece will add additional weight to the bed.
I’d expect about 5000 mm/min as maximum for your machine. More won’t make sense, I guess.

Ender 3 S1 is the 3D printer. It’s a belt driven “bed slinger”. (Y axis moves the bed). The X is on POM wheels.
The printhead is detachable and they sell laser modules to attach:
@spike80 you posted a picture of the Falcon.. Which machine is this about?
I second that in any case.
