Many bug fixes in latest Marlin, you guys @VEL337 plan to update?
Well, last firmware update is 9 month agoā¦ How long do you evaluate? The firmware you share on Github doesnāt seem to be the one in use with the printer? I checked it, the configurations are empty. I wanted to update to marlin 1.1.9
Out of curiosity, are you encountering specific problems with your delta that you expect will be addressed by a reported bug fix? On one hand, new firmware can add new features and fix bugs, but it can also introduce new problems.
What improvements are you looking to get by doing this?
@Psycho the latest marlin release was 1 month ago. Previous version where rejected. Please also note there are people on holidays and we are developing other products at the same time.
But Iām confused by your remark about the configurations. They seem like filled in =)
I like things up to date, I want my things up to date. If they are not, I update them, because new firmware can maybe bring new bugs, but new firmwares in an open source world does fix things. My printer doesnāt recognize the SD card if itās plugged in when turning the power on. My printer crashes in the bed if I cancel the print while it is bed leveling instead of going home as it should. My printer doesnāt sense a head rip off when it tries to travel outside of itās allowed distance (like, wtf, itās not even code secured the max travel???)
So yes, Marlin 1.1.9 brings lots of new things compared to this 9 month old firmware. It is written somewhere that maybe the delta will be updated. I totally understand that you are working on other things and some are on holidays since 9 months, but 9 months without a commit means dead to me. If you donāt have enough men power to sustain a project, I donāt understand the project in the first place?
Look, a coded constrain!
Too bad itās in 1.1.7ā¦
I would like to add thatās itās a gigantic work to see what you did on the firmware, as you did not fork marlin or start on a marlin base, you pushed the entire firmware at once, making all the changes invisible on git
There is no need to be agitated about this. Personally, I was curious to know what improvements have been made available recently that you were seeking.
If you know (or have reason to believe) that a new firmware update will fix a problem you are having, or if it offers some new feature that you simply must have, great! But if you continually update your already-working printer for some vague reason, you should expect to spend more time tweaking your printer than actually using it to make things.
If you want to be on the cutting edge of firmware releases, you would do well to familiarize yourself with the handful of customizations that are needed for your printer. Even though Velleman have not generally documented these for you, it is usually not very difficult to determine the settings. If you are the type to do a lot of firmware updates, you should be armed with this basic level of familiarity with your printer.
I really donāt understand why your printer would be doing all of that.
Mine is running without a problem with the stock firmware out of the box.
Did you load firmware for a different machine?
Not at all 
The second printer doesnāt, at least not the SD part. Never ever tried to cancel during bed leveling
@Dr_Vegetable Iām not getting agitated, but slightly āmehā about the support around a new printer. Iām used to communities where stuff move, where devs care, where users hack and improve. This here is a no manās land. Iām not about running nightlies on my printers, or unstable master branch. But thereās a difference between cutting edge and 9 month old 5 version old firmware base. 9 month, in this branch, is the difference between new and deprecated.
First I canāt get spare parts in Switzerland. Then, I donāt get pdf plans of the parts, I need to have inventor 2018 to open the cad files in order to have draw out the plans to fabricate the parts. Then all I get, after complaining about the poor results in printing outer skins is a ātoo bad, this is normal behavior, we donāt give a crapā from the devs. Then I canāt get the diffs in the firmware because the devs uploaded the modified firmware on git without forking as advised by Merlin so we donāt see the diffs. Then I ask for an update and the only answer is: we rejected the updates and we are on holidays or doing other things. So this raises questions, sorry. If Iām bottering, just tell me, Iāll gladly leave and never be back, but Iāll just get rid of everything oem on the printer to make it run as I wish and guess many would also
Did you try to reload the original firmware to see if it would clear things up?
I know you say itās old but it works (at least on my machine) this would tell you a lot.
Is it firmware or hardware.
No I didnāt try, though I should, as the second printer doesnāt seem to have those issues. Both are runnin 1.1.4. But Iāve linked a simple exemple of a needed fix that is included in marlin 1.1.7
I should have mentioned that on my K8200 I did hack it some (love this machine).
Not so much on my K8400.
The K8800 I donāt see anyplace to hack I mean thereās not a lot to do to it.

Thereās a lot to doā¦
- Realign the steppers, as they are not properly aligned, leading to a belt missalignement
- Belt tensionner for uniform belt tensions
- Fix filament detection problems on some printers (other have been whining about it, the guide says: disconnect the sensorā¦)
- Guide for the filament spool if you keep it on top. If not, the spool emptying, ther filament is scratching on the top plate. Ok with normal PLA, brakes wood PLA in some cases (a good start: A Filament Return pulley for Vertex Delta)
- Move screen to top (optional, depends how/where you place your printers)
- Belt guides for upper bearings
I think I forget some, should write them down

I agree about the filament detection but I checked my filament and it is the filament not the printer. moving the screenā¦ have no problem with it being on the bottom however it would be nice if it was on the top but I can live with that. I will probably end up running it on a PI with Octoprint like I do with my other 2. Filament guide once you get it done please share it once you are done.

Have you seen my post about it? Thereās accablant images of cold solderā¦ No Velleman reactionā¦
Look at this:
This is flatā¦ Thereās no update, ever, on any firmwareā¦
First, I personally resent your statement about the community here and users hacking and improving. I refer you to one of my earliest posts here in the Delta forum, or any of the half-dozen modifications I documented in the K8200 section. I am only one of many customers who contribute to the discussion here.
Second, I am not disagreeing with the need for bug fixes for the Delta, nor am I arguing against doing so if you wish to. I have noticed one or two anomalies that I suspect may be Marlin bugs. But I am not just going to blindly apply new firmware versions, hoping that they will magically cure my woes.
None of the flaws you have listed in the Delta are firmware issues. If you are asking Velleman why they havenāt yet updated to a new Marlin, I am asking you what value, specifically, you expect the new Marlin to deliver?
Yeah, thatās one upgrade. You can look down on my feelings, but this is the way I feel it here
Magic has nothing to do when reading changelogsā¦ I have given one simple exemple of something that needs to be fixed and that is present in Marlin 1.1.7. But as the screenshot I linked shows that thereās absolutely no life in the git repositories once they have pushed a blinded initial commit, Iām not waiting on an update either
