New firmware version 1.14

I have released new firmware for the Duet 0.6 and 0.8.5 at [github.com] (follow the link and then press Raw to download it). The changes in this release are:

- When multiple motors are due to step, generate all the step pulses simultaneously
- Added support for multiple drivers for a single axis (M584)
- Added support for extended step pulse width when using external drivers (T parameter on M569 command)
- Removed XYZE parameters from M569 (use M584 instead)
- Added M913 command (set motor % of normal current), allowing the motor current to be temporarily reduced e.g. for homing and loading filament
- Added Z probe type 5, which is a normally-closed switch or active-high 3.3V digital signal connected to the IN pin of the Z probe connector on the Duet 0.8.5 and Duet WiFi

User of the Duet WiFi, please see the separate notification on the Duet WiFi forum for additional changes.

Please note the following:

1. If you are using M569 commands to remap axes and extruders to different drives, that will no longer work. Use the new M584 command instead.

2. If you use the M584 command, it should come before any M350 and M906 commands in your config.g file.

Hi David, I am having problem with 1.14 on my Duet 0.8.5 delta, once I hit home all
The carriages move to the top and reach the endstops twice as expected
but then the motor will make a high pitch noise like it's stuck or something and the Duet will disconnect
need to do a power cycle to reconnect to it.

I tried running the homedelta.g 1 line at a time
It's the line: G1 Z-5 F2000 ; down a few mm so that we can centre the head
that causes the problem.

When I revert to 1.13b the problem is gone.

I have attached my config.g and homedelta.g, I don't have any M569 remap or M584 in it so I am not sure what went wrong.

Hoping the Duet 0.8 is a typo and you not dropping support for us old 0.6 owners.

It was a typo, and I've just corrected it.

Hi,

I'm sorry you are having trouble with 1.14. I am unable to reproduce the problem. I am running the Duet WiFi build of 1.14 on my delta, and the Duet build on my Ormerod (a Cartesian printer). In case there was something specific to using the 0.8.5 build condfigured for a delta, I've just bench-tested a Duet 0.8.5 configured as a delta, with two motors attached - and it is behaving as I expect.

If you try it again, please can you do the following:

1. Run M906 and M913 to check that the motor currents are as expected.

2. Try reducing that F2000 to a lower value, to see if it works correctly at lower speeds.

I'll watch for anyone else reporting a similar problem.

thanks. I thought it would be

On a side note any idea how long the 0.6 board will be supported?

The 0.6 board is sufficiently similar to the 0.8.5 board that I see no reason to withdraw support for it. However, I no longer test new releases on both variants.

Hi David, just to let you know my homing problem has been resolved.
But I didn't spend too much time figuring out what the actual problem was.
I re-downloaded the firmware, up the motor current and set the speed lower all at the same time.
only thing I know is that the speed wasn't the problem since I set it back up to 2000 there wasn't any jam.

Thanks for letting me know! There was a 1.14 beta that had problems with delta moves, so perhaps you somehow got that build the first time.

Is there a Gcode and Mcode command list for the latest firmware around someplace

[reprap.org]
I believe David keeps it quite up to date with RRF

Printer was working fine, I think I was on 1.13, but it might have been 1.12 still. Upgraded to 1.14 without issue but now my z-probe (fsr) is reading 1000 and constantly triggered where it was reading 0 by default. Not sure what to change or where to change it.

Nevermind. Just power-cycled the board and it seems to be working again.

There is a list (not maintained by me) at [reprap.org]. For a description of what each commands does, see the link in the reply by SleepyPrince.
