Rough Surface after installing Duet Wifi

Richygoat

Hello, i have a problem with the quality after installing the Duet Wifi into my Corey Printer. It was a MKS Robin Nano v1.2 installed before and the surface was ok. Now after installing the Duet it is terrible. Everything works fine but the surface is so bad. Take a lock at the pictures. Maybe someone can help me. By the way i changed nothing on the hardware and it was the same Gcode file then before.

It looks like you're getting some ringing now. Do you happen to know what you were using for speed/acceleration/jerk settings previously? Can you post your config.g so we can see what you have currently?

Generally, to reduce ringing you would want to reduce the acceleration and jerk values (for external perimeters anyway)

Hello, ringing is strange. It is one the complete side of the cube. Also above the x and y latters. Here is my config.g file.config.g

What kind of printer is it? Usually when ringing is that bad there are some loose belts or looseness in the print head mount.

Your accelerations may be a bit too high as well.

M566 X1200.00 Y1200.00 Z24.00 E600.00              ; set maximum instantaneous speed changes (mm/min)
M203 X18000.00 Y18000.00 Z360.00 E4200.00          ; set maximum speeds (mm/min)
M201 X2000.00 Y2000.00 Z100.00 E1000.00            ; set accelerations (mm/s^2)

Try adding M204 P800 T2000 which will use the high acceleration value for travels and a lower value for print moves which may help with the ringing quite a bit.
