# Ray5 10W Laser Speed?

According to Longer, my Ray 5 10W laser has a maximum speed of 10,000. I don’t see any speed difference between 5,000 or 10,000. Doing some research, I know that when in console mode and I enter \$\$, I get a string of settings. According to everything that I have researched online, \$100 & \$111 relate to X and Y axis speeds. When I entered \$\$ and looked - they are \$110=6000.000 and
\$111=6000.000 Accordingly, this indicates that the maximum speed is 6,000.not 10,000. So is Longer misrepresenting this laser’s maximum speed rating? Is there a way that I can change the settings to 10,000 according to the longer specifications for this particular laser [or should I]? I’m not sure I would ever use speed 8,000 and 9,000 or 10,000, but if Longer says that’s the maximum speed, I should be able to use that speed should I desire. Any feedback on this issue would be greatly appreciated.

As with all the other laser specs, the sellers claim as much as they possibly can while not exactly lying about it.

The good old Pythagorean equation says a vector at 45° to the axes can run at 8500 mm/min, which rounds up to a nice even 10000 mm/min. Right?

Of course, you’ll be engraving parallel to the X axis, so the actual top speed will be the 6000 mm/min you found in the GRBL configuration.

It would be amusing to know what their tech support folks have to say about your findings …

When I hear back - I’ll let you know what they said. I must say, I’m a weeee bit pissed! Thanks for a prompt reply.

Speed an acceleration values are kind of hand in hand…

The faster you want the head to move, the longer the time and the more distance it will move before reaching that speed, if it does.

You can simulate this in the preview by enabling shows traversal moves option. Lightburn calculates this from the values in devices settings → additional settings. You will see a large change in overscan…

You can change these, but their purpose is to protect the machine. If you pick up some .lbrn file, like from my machine that can run 1650mm/s, it could damage your machine. These values put a speed limit on how fast the machine is allowed to move and how fast it can do that… These are acceleration values usually in mm/s2.

You can tune your machine to be as fast as possible, there are numerous videos on how to do it, but it’s a lot of work… Educational but a lot of work.

I tuned my first cnc3018 and it walked all over the table and about beat itself and the table to death… I returned it to basically the original state…

Ensure you keep a copy of the original configuration. You can save it from the machine settings gui.

If you have too much acceleration, it will sound terrible, but really isn’t hurting anything … fields are moving faster than the mechanics can keep up with…

Good luck
