Travel speed different on X-Y axis

[Twmaster]

I don't know if this is a controller issue or a Lightburn issue, mods. please feel free to move if not specific to my CO2 laser.

Monport 100W CO2 laser, Ruida controller. Lightburn (same behavior on 1.3 and 1.4) I'm etching a pattern onto some clear acrylic. Loving the results. However I've noticed when the cutter head is moving between different locations on the job (travel between burns) in the X-axis the machine moves very fast. In the y it's super slow.

What's going on here? Can this be optimized to get the Y travel as fast as X?

Thanks.

We're having the same problem. Did you ever figure it out? We could really use some help

Typically Y moves more slowly (both max rate & acceleration) because the moving mass is MUCH greater. In X, the only thing moving is the head. In Y, the entire gantry moves. The physics of it makes moving the Y as fast as the X considerably more complicated. You need a much stiffer gantry and drivetrain (belts, pulleys, shafts, etc) and much more torque from the motors.

You can edit the machine parameters to speed up the Y, but you very likely wouldn't like the results.

I have not yet found my answer.

This machine is designed to cut in the speed range of 400mm/s and while cutting it moves very swiftly in both axes. This is not a mass issue. The machine crawls while travelling between cut positions in the Y axis in fill mode.

I do not have a co2 but on a diode there is a setting in lightburn. I think it is in edit-->device settings-->whitespace scan

[Twmaster]

That's a G-Code controller feature. Not applicable to the Ruida. Appreciate the suggestion!

This is an issue for those who have changed settings on the Ruida controller, intentional or not. You should have the controller manual on the USB drive.

Thanks Rich, we had something go goofy on the Ruida in our Monport 100W machine.

So far efforts to get a copy of the config file from Monport has been frustrating. Either they do not understand what I want or are unable/unwilling to help.

I've checked the USB and there is no controller docs I could find. Funny, there are no 100W machine docs at all. 55, 60, 80 and 130W.

The 60-150W are all the same. Unless they have changed it, the Ruida operation should be in the main user manual. Specifically, the reset for the axis controls should be on page 34 or 35 if I remember right.
