Cant laser straight raster images (always wavy in x (raster) direction)

[zuber6]

Tried many things. Here is what I get with my ramps board using grbl mega 5x:

Using identical parameters this is what I get with the dlc32:

If i take the identical picture without fill, again in raster mode I get

Not perfect, but OK. This is in vector mode with the dlc32:

No issues.

Help! Have had to go back to the ramps setup. This is on a diy machine adapted from a CNC. The only thing I can think of is that it has a screw drive on x and the 200 steps per mm is overpowering the dlc32 (lol) compared to the mega 3560 which makes absolutely no sense at all.

Using lightburn, 250 dpi, "stucki" rasterization. Latest laser firmware.

No. Still waiting for mks to respond.

Thanks calfizzi! Unfortunately I already had the max speed set to 2x the engraving speed (not intentionally). However, by setting the max speed = engraving speed I saw a significant improvement. Still nowhere near the results from a ramps board but much better. This may be because I am using a screw drive on the x-axis requiring a larger number of steps per mm over a belt drive.
Thank you so much for your input!
Seems I will still be using my ramps board for now.

Solution is in another post (thanks uasarn01and j45!). $0=10 and $1=5. Still think this is a probelm with the firmware though.
