@dc42 Really! You were right. I checked my old config.g backup.
The current value of the rod length was 350.55,H380,00 but the original value in the backup was 340.55. H384,56
After the test print, the size of the circle is OK.
I don't understand why this value changed.
But the problem seems to be solved. Thank you

Hello.
My Delta with .85 Duet prints the wrong circle size. It is OK for other dimensions such as high width. Benchy, XYZ cube - the dimensions are accurate. But if I print a circle, the real print is smaller than in Slicer. For example, 86 mm slicer diameter - 83 mm print diameter. The deviation changes with the size of the print. Can you help me where the error could be? (Sorry I'm using a translator)

I using 6mm nozzle - is it possible that there is a problem in setting the width of the lines/wiping of the nozzle?

I am attaching config.g

@Phaedrux Yes, the minimum layer time was set to 5s. then i changed it. And Cura shows a printing time of 27 minutes, but in reality I always print in 36 minutes.

please - is there something wrong with the acceleration and speed settings of the motors?
engines are - 42BYGHM810.

But I don't want to push it to the extreme. Time at 100mm/s in the Cura settings is enough for me.
But I wanted to find out where the limit of speed / quality is.

@oliof
Yes, it is a bowden extruder.
I will try to change the acceleration values.
Well thank you

@o_lampe I don't think that 0.85 wouldn't handle a 0.9 stepper. Sam D.C used them when building with this board. The whole printer cost me €200, upgrading to a newer duet makes no sense. it is my first 3D printer to learn and understand. If I'm going to upgrade, it will be a total rebuild or a completely different type.

I'll take a closer look at the Cura settings. or what other slicer would you recommend?

@Phaedrux
My config

M92 X200 Y200 Z200 ; Set axis steps/mm
M906 X1600 Y1600 Z1600 E900 ; Set motor currents (mA)
M201 X3000 Y3000 Z3000 E900 ; Accelerations (mm/s^2)
M203 X18000 Y18000 Z18000 E6000 ; Maximum speeds (mm/min)
M566 X1000 Y1000 Z1000 E800 ; Maximum instant speed changes mm/minute

And Cura start gcode

Are my configurations OK?
but the problem will probably be set in Cura. As Cura is not linked to config.g. Cura does not generate faster "benches" for me than 34 min. slower than 100 mm/s yes, but even faster than 200 - 250 mm/s it does not generate.
But I don't know why. because I don't have a printer profile set. And when I try to set the profile to, for example, FLsun 400, what is the fast delta. even with it, it does not generate faster benches than 34 min.

Hello. I have the Delta Duet, a copy of the David C. version.
Duet 0.85, 0.9 stepper, V6ED, Traxx, frame 2020, extruder 36pa5.18g, etc.
Can you advise me how to achieve faster printing?
I print in Cura at a speed of 100mm/s (walls 50mm, displacements 120mm) - Benchy in 36min at 0.4mm. the quality is good.
but I would like to try faster printing.
Any change, for example - 200mm/s, will only change the time to 34min at Benchy. Is there something slowing me down or is it Cura Slicer and its settings? (Sorry translator helps me)

Hello. I have a Delta type printer 280mm x 360mm for Duet 0.85.
it is well built with the use of quality components. I didn't build it. I bought it from the first owner. It is completely metal, carbon arms, e3D hotend, linear guides, bondtech planet gear extruder, nema 0.9step motors, leveling using an optical probe, touch color LCD for reprap. As for the components, they are of good quality for its year of manufacture. Delta now about 7 years old. The construction of the new one cost about €900.
I bought it as my first printer for learning, I liked the build quality. used cost me 200€. I am satisfied, I print at a speed of 100mm/s (edge ​​50mm/s) in Cura. I can print 3D benches in about 36 minutes. Calibrax cube XY in 11 min. T-rex cup - 6 hoursMy question is - is the print quality sufficient?
I understand that time has moved on, there are new printers, new techniques. but my opinion is that it could print better. I lubricated everything I could, disassembled and cleaned the linear carriages, replaced the nozzle, updated, tightened all the screws, added grease to the extruder gearbox, tightened the belts - basic service.
but it always happens that the Z axis deviates. On one pole I discovered a small ox in a ball. Do you think the print quality is sufficient for my parameters?
sorry, a translator will help me.
