RepRapFirmware 2.0 with RTOS in development

AS-3D Druck · 6 Apr 2018, 17:52

Quick Question on this point.
What exactly will change if you're done with Version 2.0?

Is it just more compact or can it operate faster?
Is it a performance jump like from Windows Vista to Windows 7?
Sry but i don't get it.

The use of RTOS will make it much easier for us to implement some types of new feature. I hope it will also allow us to improve file upload speed a little.

In short: More efficient use of the microcontrollers and development resources.

Which means that you can do more things with the resources you have at your disposal without sacrificing performance. In plain english that means that you can add more features, speed up certain parts and shorten development times.

For the developer a lot of things becomes easier as the abstraction level is significantly raised. Code becomes more robust as you don't have to twiddle around with low-level error prone code that often incurs limitations that makes the entire code base hard to maintain. Hunting for bugs becomes somewhat easier too.

Firmware Version: 2.0(RTOS)alpha1 (2018-04-05b2) installed on one of my Ultibots D300VS deltas. 1 print completed. Amazing progress David.

Completed 2 5 hour prints on 2.0 alpha without any issues, amazing stuff David!.

2 (minor) problems I found so far:

sometimes the ESP8266 would not boot a power up (blue led won't light up) ( a power cycle solves this).
DWC Disconnects at the end of an upload.

for reference:

Here is the last completed print on 2.0 alpha

I've uploaded multiple files from DWC with no disconnects. I'll keep my eye open for this and if it happens, report back.

After updating to 2.0(RTOS)alpha1 (2018-04-03b2) I ran a few small test calibration cubes. Everything was working fine. On the third run I walked out of the room for a few minutes and came back to the printer frozen (not moving).

I reset the printer and ran an M122.

I ran a few longer running prints without anymore freeze ups. Some web disconnects but zero issues with printing. The disconnects are new for me but not really an issue.

The firmware is working great so far.

Will there be a revised web interface to try out uploading files while printing? I tried it but the button is locked out in the current version I am running.

I've asked chrishamm to look at doing this.

RRF 2.0beta 1 has now been released. Please post further comments and feedback in the thread I have created about that release, https://forum.duet3d.com/topic/4871/reprapfirmware-2-0beta1-available.
