New RepRapFirmware 1.11-dc42 in beta

I have released version 1.11 beta 1 of my fork of RepRapFirmware here [github.com] (follow the link and then press Raw to download it). The changes in this release are:

* Switched to a new core based on ASF 3.31. This core features an interrupt and DMA-driven USB interface, hardware-scheduled ADC conversions, and supports not only the SAM3X processor used on the Duet but also the SAM4E processor on the next-generation Duet (which for now I am referring to as the DuetNG).

* Implemented chrishamm's network and webserver module improvements including Telnet streaming, and some other improvements from his fork (thanks, Chris!)

* Added a build configuration for the DuetNG. The DuetNG-specific code is not published yet.

I'm calling it a beta because of the major changes to the core, which although they are working reliably on my two printers, may yet produce some surprises. Please report any new issues you have with this release to me.

Should we be able to see the Firmware version changed to 1.11 on the DWC Settings page? I'm still seeing it at Firmware Version: 1.10 (2016-03-24)

@llamatrails, yes you should see it changed - I do.

btw so far just one new bug has come to light in 1.11beta1. On a Duet 0.8.5, the motor current for the second extruder is not set correctly, and is typically too low to be usable. I will issue an update tomorrow.

Hi dc42,

I tried building your version from source following the build instructions using the latest RepRapFirmware (14 April) and CoreDuet (9 April) branches, but I got compilation errors. It seems that the core interface has changed a bit?

My latest RepRapFirmware source builds with CoreNG, not CoreDuet. I've just updated the build instructions.

Ah I see, CoreNG includes both duet and duetNG variants.

Thanks.

Just to let you know, the firmware is working very well on the original duet. I have printed a number of different objects with no problems.
great job

Thanks for the feedback!

In case anyone hasn't realised, my 1.11 release came out of beta several days ago. The only change from the beta is that the E1 motor current on the Duet 0.8.5 is fixed - and on my board at least it is more accurate than it used to be.

Just thought I'd let you know that the update installed on my Duet 0.6 via the web interface without issue, it was a delight not having to plug into a PC to do it. Makes the upgrade process so much quicker.

thanks

I'm glad the upgrade went well for you. You have chrishamm to thank for the over-the-web firmware update feature.

Is there some known limitation that at least G28 and G30 commands can't be executed via telnet?

G28
ok
Attempt to move the motors of a delta printer to absolute positions
Attempt to move the motors of a delta printer to absolute positions
Attempt to move the motors of a delta printer to absolute positions
Attempt to move the head of a delta printer before homing the towers
Attempt to move the head of a delta printer before homing the towers

and nothing moved. The web interface on the other hand executes the homing as expected when G28 is given.

G30 via telnet will do the probing but appears to somehow get stuck after that. M122 via the web interface shows that "telnet is doing "G30"".

Which firmware version are you using? Chrishamm did some fixes to telnet support and I included them in version 1.11.

RepRapFirmware-1.11-dc42.bin is in use with Duet 0.8.5 in a Kossel Mini.
