RUIDA RDC6445g axis speed limit 400mm/s


I’m interested in both solutions or confirmations that others are having the same problem. Even just to know that others with the same controller are NOT having the problem would be a great help. Driving me nuts not being able to find a setting…:

I can’t get my controller to move the axes at anything above 400mm/s. The limits are higher than this in the manufactory setting / user settings. I’m really not sure what i’m missing.

This is an issue because at 400mm/s, the minimum laser output power is still too high for engraving.

Very grateful for any help,


Hi Luke, have you tried a test engrave at a higher speed?.
Just wondering if it’s the framing speed on the controller.

Hi Chris,

Thanks very much for the help. Looks like that was the problem, that the controller would not let me MANUALLY control faster than 400, but will engrave faster.

Thanks again,
