I am pleased to report that it works, i dropped the steps/mm from 360 to 144 and the timings from T8:8:8:8 to T4:4:8:8 and it works much better now. I kept the 8 millisecond direction setup and hold time because i feel this is what caused the even layer shift at high speeds.

Thanks again!

Nice!
How the nozzle lifting mechanism work ?

What's with all these bits? Seems like a lot of really tiny moves? Could that appear as it sitting idle? Could all the comment lines be choking it? I've never seen gcode like that. What slicer?

I would suggest making a backup of the SD card, wiping it with the SD Formatter tool and putting the contents back on.

The M301 command. When you do the autotune the PID parameters are printed at the end of the tuning.

Hmm.. I also remember that I forgot to insert the ADC values in the config.g once and they disappeared somehow. Maybe that happened to you as well?

PID is the way you normally control a temperature. This is a good site to explain it:

@nitrofreak said in Improving Print quality at high speed:

they are longer than the segments in g-code, so it probably isnt that.

What's the segment size?

I notice similar vertical bands sometimes with cylindrical sections.

in the Gcode the segments are more or less 0.2mm, in the print they are more like 0.6 to 1mm

Glad you figured it out.

Some things that may help you:

Tool offsets are never applied within tpre#.g In firmware 2.02, tool offsets are not applied in tfree#.h or tpost#.g either. In firmware 2.03beta3 they are applied in both of those files.

Ok so i think i isolated the issue to a loose contact or similar inside the wifi chip.
Reason: Recently when it didn´t work i just tapped on the wifi chip and suddenly the LED light came on signaling that it worked, and indeed it did.

Question: If i have a hot air resoldering station, can i just set it to 300°C arbitrarily, hold it on the chip and maybe repair the bad solder joint?

I'll add this to the firmware wish list. What is the preferred communication method between the filament width measuring system and the Duet: async serial, or something else?

I agree with the already voiced opinions: please no fluff or fancy pictograms that take up unnecessary space. I'm an engineer as well - so I like the general approach.

A guess a regular facelift would not hurt at this time.

I know catering to everybody is difficult, especially with all the various printer architectures, additional axis, multiple hotends, etc, is tricky. But I guess the available screen space should be best used for the most common printer types: single hotend, 3 axis, a heated bed.

@stephen6309 said in driving 24v 4A 6Ohm solenoids, selection of flyback diode:

@nitrofreak Cheap SSRs usually have a high on resistance and use lower current mosfets, like the fake FOTEKs you can get on ebay.

https://duet3d.dozuki.com/Wiki/Choosing_a_bed_heater#Section_Bed_heater_driven_using_a_Solid_State_Relay

I´m not using SSR´s, i am using mosfets to drive the solenoids.
My solution now is to connect the small mosfets to the input of the big mosfets, so as to let the big ones drive the current while the small ones just activate the big ones with 24V.
Not pretty, but seems to work until i have a better solution

I can recommend these Power Expander

I am pleased to let you know,
that the Breakout board solved the problem!
So it seems to have been the optocouplers.

The 3 microseconds seems to be enough for my speeds at the moment, i will let you know how it turns out when i push it.

Thank you

@nitrofreak said in Autotune heater values not storing (calibration voltage):

Thank you, it seems to be solved now.
I went over the config.g file, but did not find another M307 H1.
What i did is to make sure to not use the M500 and delete the config.override.
I don´t know why, but it seems to work now.

Thank you very much!

I'm glad it's working. If you send M500 now then it should store the current M307 values in config-override.g, unless there is a bug that I'm not aware of.
