New firmware 1.09a-zpl

Hello everyone,

I've released version 1.09a of my firmware fork on GitHub. It provides several improvements and a few bug fixes, but the major change in this release is the introduction of a new Makefile to build the firmware easily with Arduino 1.6.4. For Windows there is also a build script available, however that script does NOT evaluate the build dependencies yet. This means, if you're using Windows, the script will rebuild the firmware from scratch whenever you call it. If there is reasonable request for a more sophisticated build solution on Windows (as is the case already on Linux), I may expand it a bit more and add the missing dependency analysis to it.

But here again the complete changelog of my latest firmware version:

Quote

Introduced new Makefile for Linux and OS X, and a basic PowerShell compile script for Windows
- "make" and "make all" compile the firmware
- "make upload" resets the Duet via 1200BPS touch (only *nix-based OSs) and uploads firmware binary via bossac
- "make clean" purges the build directories
- Designed for Arduino 1.6.4 in conjunction with my Arduino board files (see Hardware directory)
Updated README file
Implemented M404 (filament width and nozzle diameter)
Added proper IsPrinting interface to PrintMonitor class
M24/M32 use the stack when a new file print is being started
M552 reports both the configured and actual IP addresses
Merged in (potential) fix for modulated Z probe filter (thanks dc42)
Made Z height detection more robust [G91/G90 is now checked]
Added experimental support for KISSlicer STABLE
Decreased file info scan length at the end of a file from 200K to 128K (appears to be sufficient)
Bug fix: T0 could not be used in config.g
Bug fix: FTP did not work if IP address was obtained via DHCP
Bug fix: Fixed and tested network disable/enable feature
Bug fix: Filament-based estimation occasionally returned bad time values at the end of a print
Bug fix: rr_connect returned an error message if a very long HTTP request was passed

Also, if anyone finds bugs in my Duet Web Control (especially if it's related to the Files and/or Print Status pages), please flash my firmware once and confirm they can be reproduced with my firmware as well. This would make it easier for me to track down potential issues.

Feedback is appreciated as always - if you have any questions or problems, please post them here.


P.S. If anyone wants to try out my Duet board files under Windows, please ensure you install Arduino's SAM package first. Else you will probably get a NullPointerException in the Arduino IDE, however this step is (for some reason) not necessary under OS X and/or Linux.

Hello,

I tried this firmware version. All in all very impressive but I found some small bugs.
- If there is no macro directory on the SD-card and you try to upload a macro-file you get an Ajax connection error.
- Sometimes I get a stack overflow

08:41:11
G28 Z
Error: Push(): stack overflow!

- After some time if I cancel a print and try to restart it the print does not start. I have to cancel the print again (in this case the head is not moving) and to restart the print.

To be honest I do not use a standard command order so I explain what I did (and why)

I am testing this BuildTak and this really annoys me. You have to find the right print distance by trial and error. You have to start way above the bed so here are my steps.

- Homing all axis
- Start testprint
- No layer adhision
- Pause and cancel print
- Move Z upwards +10
- Move X forwards +10
- Move Y +100 (Endstop)
- Clean the hot end
- Changing the parameter G31
- Start again (Alternativly I am homing the Z-axis only)

Hi Treito,

Thanks for reporting these problems. I know the macros directory isn't created automatically, which is why I provide a standard SD image, but I'll consider adding a check to my next firmware release to create that directory automatically on boot. I could also reproduce the stack prolem you described and I'll investigate why this is happening. I'll let you know when I have a fix ready.

Thanks for your answer. As I started there was no macro directory and since I had settings you only upgrrade your settings and you (at least I) do not care about new directory. Okay it was definitely my fault but user faults should be catched up und not lead to an error only to an error message.
