Tips to mitigate vertical artifacting Duet 2 Wifi
-
@Phaedrux I thought about crossing the belt's I might try that. Config and slicer profile attached. I will print a ringing test. slicer settiongs.gcode config.g
-
@theruttmeister Great info, this is 15mm/s.
-
That's looking a bit cleaner. Is that a faint diagonal I see or is that an artifact of the image?
A good way to test what @theruttmeister is talking about would be to reprint that object sliced at 100mm/s and then using the speed factor to change the speed by 10mm/s every 10 layers or so.
-
@Phaedrux Yeah, it's 45 degree striping. I will try it faster.
-
More pic of the stripes. Reminds me of old school A4988 candy strips.
-
For the sake of completeness can you provide your config.g, the results of M122 and M98 P"config.g". Maybe some more details on the printer.
-
@Phaedrux Sure, I posted config.g above, but I can do it again. config.g m122.txt 10/2/2020, 9:23:33 PM M98 P"config.g"
Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 265CThe printer is an EXO cube, almost just like this one.

Sorry I missed those before.
Nothing stands out as obvious in the config.
Which leaves us with mechanics and the minutiae of stepper drivers.

minutiae
Totally agree, I am pretty used to troubleshooting these types of things. I have seen this before, but never on a 2660 driver. This post was mainly to see if any other Duet users were seeing this. Great discussion by the way, enjoying it.

You might find this interesting: https://duet3d.dozuki.com/Wiki/Tuning_Stepper_Motor_Drivers
Not sure how applicable or helpful it would be in this case though.

@fcwilt Thanks for the reply,
Left is normal, right is super tight belts. -
@Phaedrux Ringing test.
-
Might be able to reduce the ringing a bit with a drop of jerk from 1200 to 700.
Hard to say if that would be enough to fix the benchy artifacts.

@fcwilt Thanks for the reply,
Left is normal, right is super tight belts.I wish I could remember exactly what I did to fix the problem. It was awhile ago when I had a CoreXY of my own design.

i switched to 0.9 degrees stepper and 16 tooth pulleys.
-
Latest print, the 0.9 degree steppers are my last resort. I think I have exhausted most of my other ideas. I will switch them out today and report back.
-
Sorry, kinda off topic, but just put 2+2 together and realised @brotherchris was Chris Riley. Love your videos, keep up the fab work
-
@NexxCat lol, thank you!
-
Yeah definitely looking like VFA. Upping your natural steps per mm on XY would be a good next step.
-
The 0.9 motors might have helped a bit, but I think this is as good as it's going to get. 1.8 on the right 0.9 on the left.
