RepRapFirmware 3.6.0-alpha.2 for Duet main boards available

ProteanReverie · 1 Aug 2024, 22:52

I have begun testing on two machines that are nearly identical, but one with a Duet 2 controlling it and one with a Duet 3 controlling it. I am very excited about the results I am seeing in print quality improvement. I have not yet encountered any noticeable issues with 3.6A2+3. Prints have run largely unattended, so if there was anything unusual that happened mid-print I could have missed it. Results off of the Duet 2 setup and Duet 3 setup look the same for the tests I have run.

Gcode was identical across both machines and both firmware versions. Input shaping is configured as ZVDD F15 on both machines. Pressure advance is enabled with a value of 0.04 on both machines.

These tests were done with a Hemera Revo 0.4HF nozzle and PETG material. I am also starting tests with a 1.0 nozzle but do not have that data yet.

Duet 2 setup:
Duet 2 Wi-Fi external antenna
Duex 5

Here is an example of the difference in ringing/ghosting from the Ghost Text model. 3.5.2 is on bottom, 3.6A2+3 on top.

Please let me know if there is any other information I can provide that would be beneficial.

@ProteanReverie Sorry I'm not up to speed on the latest features, but is there some particular feature that has to be enabled or configured to get that improvement in the ringing, or is it just improvements to the RFF code?

@Notepad thank you for your guidance. I was able to reproduce the issue and here are the output files.

The difference between my pictures is only an update to the RFF code, but the difference in the code pertains to how input shaping is handled. So, if you are using input shaping the update should improve things. If not, you would likely need to configure input shaping as well as applying the update. You can learn more about Input Shaping for Duet here https://docs.duet3d.com/en/User_manual/Tuning/Input_shaping

Haven't used my RRF printer in a few months due to it not printing as well as the Qidi. I saw this post and decided to dust off the Jubilee and load up 3.6 alpha and give it a go. I only have a few prints in but see a big improvement in print quality over the 3.5 version it replaced. So far not having an issues but have only used a single tool. Will try to do a multi color this weekend.

@dc42 I've been having major problems with bed leveling. One Z stepper either adjusts the wrong direction, or doesn't move at all. I had been doing extensive work on bed.g a few weeks ago and got it working perfectly. This problem doesn't correspond with that, but it gives a time frame which indicates to me there's something with this alpha version since that's the only major change since then. At that time I had probably run the routine 100 times in a row, working on LED issues. The actual leveling worked well.

balajiramani · 3 Aug 2024, 07:21

@DonStauffer I too am having a similar problem with bed levelling. Printing with 3.6.0-alpha2+3 works fine and the input shaping is absolutely awesome! BTW, the printer I have is a delta.

The input shaping is so good that I am able to increase the accleration and jerk, without any artefacts. I was also able to drop the pressure advance value. I went from 0.21 to 0.14.

DonStauffer · 3 Aug 2024, 15:25

@balajiramani I need to look into input shaping. The pics I've seen a really awesome.

dc42 · 8 Oct 2024, 18:44

I've put new 3.6.0 alpha RRF builds at https://www.dropbox.com/scl/fo/yc7mnauicu5vqw6yegeq7/AKnV4j8k1MCADG4VE4EIG6Y?rlkey=skjxh23i9c953yvxm2tb8qr36&dl=0. Some notes:

The issue with bed tramming might be fixed. I don't have a suitable machine to test it on.
Scanning Z probes are fixed (they didn't work in previous 3.6.0 alpha releases)
Also included are 3.6.0 alpha versions of some expansion board firmware (not EXP1HCL or M23CL). You can revert to 3.5.2 versions if you have any issues with them.

See https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-Beta#reprapfirmware-360-beta1-in-preparation for more details.

@dc42 Im just about to start deploying and testing 3.6.A2+4. and in a few weeks I should have a handful of Duet3 equipped machines ready for testing the firmware on.
Regarding the bed tramming bug on A2+3 I have not been able to repeat this bug using Duet2 hardware on a 2 z-motor setup. I have not tried this on my 3 z-motor setup yet.

dc42 · 13 Aug 2024, 19:45

@Notepad the latest build is 3.6.0-alpha.4 which you can find at https://www.dropbox.com/scl/fo/cckwiq91gn16hvl1zdjnp/AF0SMEtkVfiArSPeYaBDGPY?rlkey=kqkknk9q1kiq684u4s55ce8d4&dl=0.

@dc42 I am still seeing failures and head crashing into the bed on running G32 calibration on a delta. Is this a known issue?

dc42 · 14 Aug 2024, 06:52

@balajiramani are you definitely running the 3.6.0-alpha.4 build? There was a minor bug in G32 calibration on deltas in early 3.6.0 alpha builds but I fixed that some time ago.

dc42 · 14 Aug 2024, 06:54

@DonStauffer does that same macro work if you invoke it from the DWC command line using M98?

balajiramani · 14 Aug 2024, 07:04

@dc42 Yes, I downloaded it from the latest link you posted. Here is a screenshot.

dc42 · 14 Aug 2024, 13:20

@balajiramani my delta is working perfectly with alpha.4. Please post your bed.g file and provide more details about when the probing sequence goes wrong.

balajiramani · 14 Aug 2024, 13:25

@dc42 Here is a video that shows the crash - https://forum.duet3d.com/assets/uploads/files/1721977512327-pxl_20240726_065615215-2.mp4. The motion from from one probe point to the other is more of a 'U' shaped travel, instead of a straight line.

Let me know if you need any other information.

Here is bed.g file.
