![]() ![]() I know, that this isn't a solution, but it may help to find out whether the ringing is really caused by the belts.? (the line just wrapped around the motor shaft 5 times to ensure enough friction). So there won't be any toothed pulleys in the hole system any more. Next, I will try to replace the belt by a fishing line. So I could compare the print quality from 200 steps/mm with 80 steps/mm… But there was no difference. ![]() (and also tested 16 teeth Pulleys instead of 20. So it is still visible but you can't feel it any more.Ĭhanged to 0.9° stepper motors to increase the steps/mm. I also had to loose the belt tension a lot to reduce the ringing even more. ![]() Here a photo of the new belt-lineup (only for one motor otherwise my painting skills would be to confusing ) I flipped the belts, so all Idlers are run on the smooth side of the belt (and are changed to smooth Idlers with no teeth) except the Pulleys of the Stepper motor. Maybe can join the discussion to bring in some light into the darkness I thought about an issue with M669 which was introduced in RRFW 1.1.9 - are there potential collisions with M667 or known issues related to CoreXY? As the motors were changed, it can be related to soft- or hardware issues. In conclusion, we have to find all factors that can cause kind of a stuttering in the motors. You can clearly see this sinus wave like pattern with a ball pen mounted on the x carriage painting on paper. The only measurable movement within a linear x move(as seen in the video) is into the y direction (+-0.2mm = 0.4mm). So we continued debugging within the XY frame, by measuring if the Y carriages does bend in x direction while moving x, and they didn't. There's no measurable bending or movement of the frame. We measured the rods, the movement was ~0.05mm. As written in the OP, the belts, pulleys were changed, so they are out. I was focused on the mechanical subsystem since we did some tests today. It seems to be more complex in this case. I am unsure if we did test the M350 X16 Y16 while setting the I flag to 0 - for sure we did test a lot and discussed a bunch of common and uncommon things. ![]()
