Power drop with speed

[MichaelPragner]

When i drop speed mm/Sec my power also drop ?
This means i cannot cut at low speed and high power.
Example: 10 speed and 80% power only about 5-6 mA on Amperemeter
200 speed and 80% power about 15 mA
I must have changed some settings by mistake ?
Can you guide me ?

There are two settings for power: power at low speed and power at high speed. What are yours set to?

Where do i check that ?
My Potientiometer is set on 8 out of 10(Max)
When i run 80% Max power and 25% Min Power AND Speed mm/s 10, Amperemeter goes to 5-6 mA
When i run same job with same power settings BUT speed 100 Amperemeter goes to about 20 mA

These can be found in the settings of your layer.
See the following example I found on the forum and marked the relevant settings:

Note: values are arbitrary. Just wanted to show you where the settings are.

Picture of my setting

Looks like i cannot paste or drag a picture into the chat?

I doubble click the Layer line in the “CUTS” box on the right side…and new window open…Cut setting editor-Lightburn Beta 0.9.04
And there i have
Speed 100
Max power 80
Min Power 25
But if i change speed down, the power that comes out of the machine in mA also drop down

Hope it makes sense, what i am writing ?

When cutting, set the Min Power value to the same value as Max Power.

Ruida / LightBurn won't cut below 10mm/s

This isn’t a LightBurn issue, but a Ruida one that’s quite common. There’s a controller setting called “Start Speed” that defaults to 10mm/sec. At that speed, power starts ramping up from Min Power to Max Power. Cutting at or below that speed means you’re using Min Power only, so if you’re cutting slow, set both Min and Max power the same and you’ll have no issues.
