Title: The problem of working at low speed
Hello.
I have the following problem.
I use ddcsv2.1 to control the laser.
When the cutting speed decreases, the laser starts working incorrectly. Problems begin at speeds below 1000 mm / min and increase with decreasing speed. Photo attached. On the direct parts of the work there is no problem. You can help?

Sorry, I don't quite understand.Your question is: is the trajectory incorrect at low speed, or is the intensity of the laser faulty?How do you control your laser?

The trajectory incorrect at low speed.
At high speeds everything works correctly.

Ok, please upload your configuration file (/ MNT /nand1-1/setting) and nc code.

I used this configuration file to run this nc code and found no problems. Which firmware version are you using?
You can install the firmware in the attachment and try.

How I can install the firmware?

Extract the install directory of the archive to the usb stick, insert the usb stick into the controller, and power it on.

Hello.
I reinstalled the software. Problem still exists. At high speed (F = 1500 mm/min) draws closed regular circles. At low speeds (F = 100 mm/min) , the laser path is irregular. For some reason, on the arcs the direction of movement of the laser changes and instead of a circle a strange figure is obtained. Draws straight lines correctly at any speed. I attach the photo again: work with the same nc-code at different speeds.

You can try to increase the Microstep resolution of the drive and reconfigure # 34-# 36, preferably greater than 400.
