Problem with circles and diagonal moves
-
Hello,
I have built a Voron 2.4 with a Duet3 6HC and 3HC combination. While making circle or diagonal moves the X and Y steppers are bucking... Only a move in x or y direction is not a problem.
Here is the video to demonstrate it:
Circles with Voron2.4I have loosen the belt tension a little bit and increase the current of the x/y stepper motors. But it didn't help...

It's better with higher speed...

i assume you are on firmware 3.1.1?
how did you generate the circle movement commands?
can you try and enable a different jerk Policy (M566 P1)
-
M350 X16 Y16 Z16:16:16:16 E16 I1
The extra 16s on Z there are unnecessary.
Can you post a sample of gcode file that produces the problem?
Do the motors behave the same with the belt disconnected?

How is it correct?
-
@medicusdkfz how is what correct?

This is a video with various speeds with the circle movement...
It's a lot better now but not perfect.
This is the new M566:
M566 P1 X1000.00 Y1000.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min) -
@medicusdkfz do you have mesh compensation active? Increase your z jerk to 60
-
I have isolated the noisy problem. It's kind of a resonance frequency with biggest peak at 67 mm/s and a smaller peak at 133 mm/s in x and y direction.
I've started a macro with various speeds from 1000 mm/min up to 10000 for x and y. Mesh is not active at this time. Only for real printing purposes.
-
Regardless, still a good idea to raise your Z jerk if you intend to use mesh compensation.

Hi,
the biggest problem lies in the stepper motor setting. I reduced the acceleration and increased the maximal speed and currents a little bit. Now it fine. The noise is almost gone!
Thank you,
Pierre -
Can you link the specs of the motor?
What did you end up with for settings?
Might helps someone in the future. -
Yes, a little bit later. While I'm printing, I have the strange issue, that my web interface lost the connection to the Duet3 6HC. After some minutes my Duet reboots.
-
@medicusdkfz
please post the M122 after the reboot -
For the moment I cut the web connection to the board while printing.
-
After connection lost and reboot of the Duet3 6HC while printing (!), here is my M122...
Therefore normally I close any web connection in every browser to the 6HC! That is the only way to prevent this issue... I'm running the RRF3 3.2-beta4!M122

Can you try beta 4.1?
-
I have but there are more problems. My 3HC don't wake up after a soft reboot. Only when I switch off the power and power on, the 3HC is there...
I changed back to 3.1.1...
