 # How can I tell what my machines mas speed is

How can I tell what my machines max speed is. I was trying to find how to tell in passed forum but could not find it. I have a 15000mw open frame diode laser. Below are my settings from the Console. I am trying to determine what 1/4 speed, 1/2 etc would be.

What machine do you have? That would help. You bed is set to 200x200. Is that correct? LM2? When you burn, you’re gonna set it for 1200mm/min or whatever works well. You’re never gonna run at MAX speed. Max, 1/2 and 1/4 speeds are kinda useless. BUT, \$110, \$111 and \$112 set the X,Y and Z-axis maximum rates. Yours are set to 5000 ( X&Y ) Why do you need to know this?

15000 mw Blue CNC Laser Engraving Machine 40"x40". I was working in another program that just used a slider. I noted the speed at 1/4 Power and about 100% speed. I just want to know what the max would be so I can figure from there. I don’t set speed above the machines capabilities. I am just going to use LightBurn going forward.

So it looks like speed max is 5000 so 1/2 would be 2500. This machine did not come with any suggested, speed, power or Z manual height settings.
