RepRapFirmware 3.6.0-alpha.2 for Duet main boards available

dc42

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

@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

@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

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

balajiramani

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

dc42

@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

@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.

@balajiramani it sounds to me that segmentation is not working on those moves. If you send M669 without parameters, what does it report?

balajiramani

@dc42 Here is what I see:

M669
Kinematics is Linear delta, 100 segments/sec, min. segment length 0.20mm

@dc42 Just had time to TRY a print with the alpha.4 binaries you uploaded the other day (on both the D3 Mini & the 1LC), and the bed leveling seems to be working.

BUT now the extruder won't extrude (or retract for that matter), either through G-code or if I to use the "extrude buttons" in DWC & PD.

When I canceled the print on PD i got these error messages:

CAN response timeout: board 121, req type 6044, RID 220.
Error: at column 2: G10: hA
CAN response timeout: board 121, req type 6029, RID 222
CAN response timeout: board 121, req type 6044, RID 223

Which is new behaviour from alpha.2+3.

AND the hotend heater (connected to the 1LC) won't turn off. Both DWC & PD show active/standby heat to be 0, but the heater is still at working temp (255c).
If i manually try to input 0 in active on DWC and push enter i get this error:

M568 P0 S0
Error:  at column 2: M568: P

The only way I've found to actually make it turn off/adjust the temp down is to power toggle or restart the printer.

@Exerqtor What version of the firmware do you have installed on the 1LC?

I just tested if the extrusion works while idle, which it does. I'm about to start a new test print (same job g-code as earlier) and see what happens.

I'm letting the test print finish to see what's going to happen.

DonStauffer

@dc42 I didn't try it and I reverted to alpha 2. It's called from the last few lines in config.g so I didn't think it would be different.

I reinstalled alpha 4 and yes, the error occurs on the M260 lines when the macro is invoked from the console using M98.

dc42

@DonStauffer my apologies, I accidentally disabled M260 in that build. I will reinstate it in the next build. Meanwhile, M260.0 should do what you want in alpha 4.

edsped

Am I the only one having connection interrupted errors with the most recent build? I'm hard wired into a Ubiquiti network if that matters.

Bed leveling is working as intended.

@edsped said in RepRapFirmware 3.6.0-alpha.2 for Duet main boards available:

Not sure what's going on, I reverted back to 3.5.2 and the dropped connection persists.. All works well using the paneldue but the web interface is all but unusable and sometimes I'm unable to reconnect for several minutes. Not sure what got hosed but something is surely borked.

@edsped I see connection errors too. Do your connections errors go away if you put the PanelDue on the Setup page so that it stops polling the 6HC?
