Problem with circles and diagonal moves

[medicusdkfz]

@Phaedrux said in Problem with circles and diagonal moves:

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?

[Phaedrux]

@medicusdkfz how is what correct?

[medicusdkfz]

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)

Circles with various speed

@medicusdkfz do you have mesh compensation active? Increase your z jerk to 60

[medicusdkfz]

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.

[Phaedrux]

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

[Phaedrux]

Can you link the specs of the motor?
What did you end up with for settings?
Might helps someone in the future.

[medicusdkfz]

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

[medicusdkfz]

For the moment I cut the web connection to the board while printing.

[medicusdkfz]

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!

[Phaedrux]

Can you try beta 4.1?

[medicusdkfz]

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...

[Phaedrux]

Did you update the firmware on the 3hc as well?

[medicusdkfz]

Of course, I did...

[Phaedrux]

Just checking.
