Fur coat and no knickers...

thats not always a bad thing

In any case there are no two ways about it there has been a miss-match between expectations and deliverables for Duet3+RRF3 and a unfortunate dependency between the two. Clearer communication of limitations would probably have helped, but hindsight will always be 20/20.

3.2beta1 is just out, so there is that!

I did suggest a while back that Atlassian's Jira (including the cloud hosted versions) are free for open source projects.

issues on the github work rather good without all the overhead and bloat atlassian likes to add. and if ppl don't want to report a bug on the github issue I doubt they will do it on the jira

@arhi I expect we would still report the issues on the forum and then only add them to whatever issue tracking system that was used once accepted

The problem with github issues up to this point is we have people asking for support due to configuration problems on github rather than on the forum.

arhi

@T3P3Tony well I'm not a github guru but I'v seen this set pretty nicely on other projects where you easily shoot a "canned answer" to those asking for support to "go post on forum" and mark the feature request and bugs accordingly with tags ..

T3P3Tony

@arhi yes for sure that is possible, we can consider it.

good example is octoprint .. very lively forum and very lively github...

smoothieware is also an interesting example, they go to extreme's to shut down any non bug related talk on the github

To those who have complained that we haven't published maximum step rates for a while: why don't you measure them yourselves? Or if it's for a planned purchased of a board you don't have, ask someone else to. It's not difficult:

Work out a long move that you can use on your machine to test the step rate. It needs to be long enough that most of the move will be at the requested speed, not doing acceleration or deceleration
Select x256 microstepping
Send M122 to clear the hiccup count
Execute that move
Send M122 to read the hiccup count
Repeat the last 3 steps at different speeds, to find the speed at which the hiccup count increases dramatically. For a 300mm move at x256 microstepping, I reckon that 50 to 100 hiccups is acceptable, more is not.
Use the steps/mm and the speed you measured to work out the step pulse rate.

...or run higher than 16X micro-stepping on extruders connected to a mixing hot end

You may find that you can do that with the 3.2beta1 expansion board firmware.

esphome or homeassistant(?) has a thing on their github requiring any issue to conform to a template, and some voodoo to weed out "it doesn't work" and "its the wrong flavour".

in the near term, having developers register bugs and posting to the forum threads where an forum topic has been escalated to a bug might be a start to avoid the issue oozeBot raised. power users will likely pick up on the trend and register issues themselves when bugs are confirmed to offload the developers?

dc42

What I would really like is to be able to restrict creating issues to particular users/email addresses only. That way we could add users to the allowed list when they have shown on the forum that they really do understand when they have found a probable bug.

As it is, there are so many issues posted on github that are really support requests that I rarely look at github issues. Just occasionally I am surprised to find a new real bug report when I do.

@dc42 it might be low hanging fruit to just add a template?

maybe users would self redirect if they that was part of the template, as opposed to a blank slate?

example https://github.com/esphome/issues/issues/new?template=bug_report.md

Maybe, but I don't have time right now to read enough of the documentation to understand github templates and design one. I would be happy for someone else to do that.

Because until very recently hiccups for expansion boards were not reported. OK, so it's fixed in 3.1.1. but prior to that, I had no way to test because I couldn't get a hiccup count. Hence the reason that for 12 months or so, I had to keep asking the question (but never got an answer).

Or if it's for a planned purchased of a board you don't have, ask someone else to................

Seriously? That's your answer to the question "what is the maximum step pulse frequency"? - Get a forum member to test it and report back!

Methinks if I was an OEM looking to purchase (say) a few hundred units per month and received that response to the question, I'd be dropping Duet as potential candidate faster than a hot brick.

And I'm here just like "what about RRF 2?" lol.

Why did we throw that baby out with the bath water?

gtj0

It's also hard for normal users to file a github issue because you have to know which github project to create issues in. RRF? DSF? DWC?

Don't get upset, I'm just being direct here.

It appears to me as if the Duet team randomly jumps from one board to another. That's certainly not what the Duet team intended. There is great hardware designer and programming talent here, but, sorry, it's all just excuses. We do in part pay for the software when buying the hardware. Yes, it's open source software, but a requirement to hire a developer is not what's on Duet's product page. This approach is somewhat... Chinese. You buy a cat in the box and have to hope they will fix the missing legs. It's still a cat that can purr, but it's missing its legs and all you got to complain to is some overloaded Chenglish speaking guy 12 time zones away. You sorta bang at the door until you're tired. The only difference is that the forums are English.

Well, I won't buy or recommend a single Duet board until Duet 2 works 100.000000000000% and I mean all the tiny last corner cases directly or indirectly related to motion. Everything else is just the rate of odor decay of the icing on the cake. I couldn't care less for many improvements already done.

Yes, I "hired a programmer", i.e. myself and got it working to 99.9999%, but it's not good enough for me.

In total the Duet 2 is the workhorse on my printer, so, yah, OPEN SOURZ YEEHAH. ¯\(ツ)/¯

EDIT: Forgot to mention that in China you don't need open source. You just steal the product and you're fine. I'm not saying this is a negative or a positive.

with that requirement then going with a different vendor is probably a good idea; however i suspect it'll be a challenge in its own right to find a suitable vendor for that requirement?

Now try that AFTER you've designed and built a printer around a vendor. I'm a vendor too and have to rely on other vendors. The discussion is near pointless. As people have said, it is what it is. The Chinese don't care either.

I'm sorry, IMO you have an unrealistic expectations, especially in the middle of a pandemic which has seriously affected electronics manufacturers, including Duet3D.

Motion-related issues are of course our priority. I am not aware of any significant motion control issues, apart from a recent report of a small (3% in RRF 3.1.1) over-extrusion when a high value of pressure advance (1.0) is used.

So please do take your business elsewhere, because it's clear that you will never be satisfied. Good luck finding a supplier who can satisfy you. Maybe if you pay 2-3x the price for your boards and also pay a hefty support contract, you will find a manufacturer who will provide you with a fix for 3% over extrusion with high PA less than two weeks after a user has reported it as a problem in current firmware.
