RepRapFirmware 3.6.0-alpha.2 for Duet main boards available

curieos

Does alpha 4 still work with toolboards running 3.5.2? I'd like to give this a try, but the toolboard on my Micron is a Fly RRF 36 and it doesn't look like team gloomy is releasing 3.6 alpha builds.

@curieos Looks like a question for @jay_s_uk @gloomyandy

Yes it does.

@Notepad I don't think there are any expansion builds publicly available for 3.6 yet. We did make a build of 3.6 for mainboards available here: https://discord.com/channels/711873626080804914/762765744278208512/1263573562090848286

As DC42 confirmed existing 3.5.2 builds for expansion boards can be used with 3.6.

@dc42 checking if there is any update on this issue?

@balajiramani multiple issues have been discussed here, it helps if you're specific on which one you are asking about.

I've done a couple prints now on my Micron, and input shaping is looking way better. There's a symptom I didn't realize was due to the old input shaping algorithm; large ringing artifacts on organic supports. My guess is it's due to the high segmentation of those moves, but I could hear the printer make an almost grinding noise. That's all gone now.

The main quirk I'm noticing is slow probing. I'm running a klicky PBC and before, when the probe triggered, it would retract near instantly. Now it pauses after triggering for a brief moment. I have it set up to do multiple samples, and it seems like the first sample is always the slowest when retracting, but every sample has a brief pause.

Pressure advance also seems kinda weird. I need to rerun the tuning pattern to be sure I'm using the correct value, but it looks like turning it on at all has a very negative effect on surface quality. It's most pronounced on the latest print, but that's still in progress.

@curieos thanks for your feedback. Re the pressure advance, is the extruder driven by the main board, or by a tool or expansion board - and if so, is that board running 3.5 or 3.6 firmware?

@dc42 It's on the mellowfly toolboard running 3.5.2

@curieos OK, please upgrade to 3.6.0-alpha.4+3. See my next post.

All those running 3.6.0alpha builds, please see my announcement at https://forum.duet3d.com/topic/36421/reprapfirmware-3-6-0-alpha-4-3-available-for-testing/1 and upgrade to that version. If you find any issues, please continue in that thread. I shall lock this one shortly.
