RepRapFirmware 3.6.0-alpha.4+3 available for testing

[dc42]

I've posted the latest RRF 3.6 builds at https://www.dropbox.com/scl/fo/11sr8rwqogb2khks06648/ALTHIHIOxnk9HqiAaR18Q6k?rlkey=xky4ymfqk6r7x373vzn270tu0&dl=0. If you are running an earlier 3.6.-alpha build, please upgrade to these files. The change log is at https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-Beta#reprapfirmware-360-alpha43.

EDIT: latest build is now at https://www.dropbox.com/scl/fo/u79134f365jdacqsm0km3/AKMSKB_Fz63WH4hqLkIphuQ?rlkey=bpa9lja4jylkpu9syjfp31rho&dl=0. The main build binaries are version 3.6.0-alpha.5+1. Expansion board binaries are 3.6.0-alpha.5.

@dc42 When trying the new alpha4+3, I get "movement halted step timing error occurred (code 3) Please reset the controller"
Got same error with two different files. Duet2wifi standalone on a linear delta

[edsped]

I had the same issue....

[gloomyandy]

@edsped What sort of printer are you using? What controller board?

[curieos]

It appears I too had this issue. I completed the exact same print twice on alpha 4. I didn't have my computer on to catch the error in the log, but my print was halted and it did not respond to a pause. As the log says, Duet 3 Mini 5+ wifi, and I have a Fly RRF 36 toolboard (on 3.5.2). This is on a Micron (miniaturized Voron 2.4).

Edit: I'd also like to report that there wasn't an improvement in pressure advance behavior. Should I be running a 3.6 alpha on my toolboard too?

[balajiramani]

@dc42 I just tried this version on the linear delta and the bed calibration bug still exists.

@Adrian52, since you have a linear delta, are you able to run a bed calibration?

Thanks,
Balaji

[Adrian52]

@balajiramani I run delta calibration using the smart effector probe without any obvious problem, with residual error usually under 0.02. I normally don't need to use mesh compensation.

Thanks everyone, looks like we are getting a lot more step error code 3 than before with this build.

We've found a few other issues too:

• After a homing move there was sometimes a short pause before movement resumes. This is now fixed in the 3.6-dev source code. It may affect probing moves too.
• When an endstop switch is triggered during a homing move and the drivers concerned are on an expansion board, it's normal for the expansion board motor(s) to overshoot very slightly and then move back to the correct position. However, in this release the overshoot is often somewhat greater than it is in RRF 3.5.3-rc1, resulting in a noticeable jolt. This occurs with main board firmware 3.6.0-alpha.4+3 even if the expansion board is running firmware 3.5.3-rc.1.
• When EXP1HCL boards running 3.6.0-alpha.4+3 firmware are used in open loop mode, the start and end of the moves are jerky. Closed loop and assisted open loop modes work properly. This probably affects M23CL motors too.

I won't be able to fix these issues for a while because of other commitments.

Folks if anyone has a print that generates a "Movement halted error" after a short time (so relatively early in the print) can you please post the gcode file and the config.g file for the printer. That way we can try and reproduce the issue.

@Exerqtor did your error occur on the first print after a printer restart or had you already printed a previous file? I ask because your m122 is showing a hiccup delay, but no hiccups (maybe you have run m122 more than once after the failure). If this was the second print that failed can you test to see if the same print fails as the first print after the printer is restarted?

@Adrian52 I haven't been able to run a successful delta calibration with the 3.6.0 firmware. This was not an issue in 3.5.2. The head crashes into the bed. The movement is not straight from one probe point to the other and it more of a 'U' shaped move. Can you post your bed.g, so that I can compare it with what I have?

Thanks,
Balaji

[dc42]

@balajiramani a U shaped move suggests that the auto-generated travel move is not being segmented. Please run M669 without parameters, to check that segmentation hasn't been disabled. Also please send M115 to verify that you really are running the latest alpha firmware.

@dc42 Here are the output of the commands:

Those of you with the code 3 errors, how long was the print running? I think I've just found a bug that could cause a code 3 error if a print was running about 47 minutes after the Duet 3 was booted up (about 38 minutes for Duet 2).

[dc42]

@balajiramani thanks. Are you sure that the delta radius and rod length are set to approximately the correct value before calibration? I don't think anyone else has reported issues with delta calibration running recent 3.6.0 alpha versions, and calibration works perfectly on my own delta. So I am wondering whether the reason for the U-shaped moves is that either the rod length or delta radius is set incorrectly. Possibly there is an error in your M665 or M666 command and RRF 3.6 responds differently to that error. So please run M665 and M666 without parameters and check that the reported values are as expected.

[tas]

@dc42 Duet 2 Wifi on an Ender 5 plus stopped with the code 3 error. Your 38 minute mark sounds about right but I don't have an exact time when it stopped.

I installed 3.5.3 rc1 and ran the same gcode without issues.

For me it happened roughly 35min into the print.

Yeah it was the first print after the update! And you're right, it was the second M122 output. Here is the first output (including the print startinfo, error message etc:

@Exerqtor @tas thanks. I will release 3.6.-alpha.5 after doing a couple of test prints.

[Exerqtor]

@dc42 Awesome, i will install it and try the same testprint right away

[balajiramani]

@dc42 The delta calibration procedure works fine with 3.5.2. With 3.6.0-alpha*, I run into the issue. I checked the values of M665 and M666 in both 3.5.2 and 3.6.0-alpha and they are the same values.

Here is what I see with 3.5.2:
