@fmalpartida, @avluis, @vandarin, @thawkins, @arno-millenaar, @Natealus , @Sniffle are candidates to test out if auto leveling is working

[boelle]

anyways... recreated this to print to the top....

how are the lavest DEV branch working? is autolevel working as it should?

[fmalpartida]

Apart from cura not playing ball, dev branch is almost ready for promotion.

[ntoff]

I don't have any probes or anything but I do have a printer that I built specifically for fiddling with that uses a mixture of A4988 drivers and DRV8825's that usually has a reasonably recent version of the dev branch on it.

Currently printing a squirrel, will throw the test object at it once that's done.

[clefranc]

@boelle I've just added a levelling probe to my delta, can you update my description? I also have a RepRapDiscount Smart LCD Controller I can switch with the full one on my delta.

@thinkyhead I'm totally new to auto bed levelling, do you think you can update the wiki? I found an older Marlin Documentation folder with still BedLeveling.md inside. Is it still usable?

[fmalpartida]

@boelle, could you update my profile with the current setup I am doing some testing:

• Controler: SAV MkI (AT90USB1286), integrated uSD card reader.
• LCD: SAV 3D LCD (Shift Register LCD panel with rotary encoder, kill and home buttons)
• Mechanics: CoreXY
• Extruders: 1
• Inductive sensor + Autobed leveling
• Prints via: SD Card
• Host interface: CURA, Octoprint

Alternative setup:

• LCD: SSD1306, rotary encoder, kill and home pins
• Mechanics: i3
• Extruders: 1
• Hotbed: 1

[PxT]

With a Printrbot Metal Simple (inductive probe): I compiled leaving all the settings at default other than what was needed for my board, sensors, probe points & endstop directions.

M851 is at Z-0.7, that offset works perfectly with my Printrbot-fork firmware. With the current dev branch, the printer probes all points as expected but then drops the nozzle a little more just as the print starts, driving it into the bed. Homing by use of a software button works fine. My start gcode is: G28 X0 Y0 Z0 G29

Let me know if you need any more info on my setup.

[chris-bo]

3 point leveling with sled mounted probe works fine on my i3. Electronics are Sanguinololu 1.3a with ATMega 1284p running at 20Mhz and Full Graphics LCD. Grid leveling does not fit into progmem. If necessary I could test it without LCD.

I tested the current Marlin 35af5ef.

[boelle]

3 point is enough

if the bed is bent etc the grid method could do some tricks.... but really then i would rather get a flat bed

[geekgarage]

I got a Prusa i3 frame with RUMBA board (dip-switch version) with inductive sensor for auto level, dual Z-axis step drivers and reprap discount full graphics, e3D v6 hotend with direct drive and there is a few questions I can't find an answer to, as this is my first printer and i got it used prebuilt 2 days ago:

What does this do?

define ENDSTOPPULLUP_ZPROBE

Also in advanced config i enable

define Z_DUAL_STEPPER_DRIVERS

since i got my Z step motors running on their own driver as a single driver don't have enough power to run two motors (this is tested) in the code i see it asks for Z_DUAL_ENDSTOPS that i don't have, and i get a compile error if i comment it out (that do make sense tho after looking at the code) But should i just ignore this or should i install two endstops as i plan on adding Z max end stops?

I don't have a Z-min end stop switch, i'm using the inductive sensor for the Z-axis stopping. and i only have X and Y min end stop switches tho I will be upgrading shortly with XYZ Max end stop switches hence the Z endstop question

I finally found out how to get Auto Home to work, didn't know that i had to define Z_PROBE_PIN in the pins file but after i did that, and enabled Z_PROBE_ENDSTOP it worked using auto home.

Here is my configs Configuration.h http://pastebin.com/uLhsW89M

Configurations_adv.h http://pastebin.com/vwikWtBk

Sorry in advance if this is a bit noobish and shouldn't be asked here, but i'm stuck for now trying to get the last bit to work. If you have a better site to ask these questions please refer me.

[fmalpartida]

@boelle @thinkyhead hi folks, tests on the development branch look good and in shape. I think it is a good moment to move the code to the integration branch and get it ready for testing and eventual release.

[fmalpartida]

What I then suggest is to freeze the integration branch for new features and only fix in the integration branch defects that the testers report on it that make it inviable for release.

[Wackerbarth]

WAIT, I think that you are rushing things! There are still some pull requests that affect the configuration files and features for the delta printers that need to be integrated.

[thawkins]

Speaking of which, what is the best practice for stopping local changes to Configure.h from leaking into pull requests. How do folks normaly ensure that is not happening.

i noramlly make a copy of the folder that is used to sync to github.... and then place the folder somewhere else where its easy to get at but far from the other folder

ie on windows the desktop is my choice

[epatel]

@thawkins I use https://www.sourcetreeapp.com that gives a good overview of what goes into a commit. It also makes it very easy to commit single lines. And is easy to diff different branches (i.e. I use a local branch for the private dev before merging into anything that goes to github). But also, trying to be disciplined. Like carefully look over the Pull Request carefully before pressing the button on github.

[fmalpartida]

OK, how about up issuing the integ branch and continue with the dev branch. That way people can start testing it. In the mean time continue with dev to troubleshoot the delta's auto bed leveling.

[boelle]

is auto leveling only an issue for Delta's now?

i thought there where trouble also with normal printers

i cant be on pc since we will have electricians shortly and they will cut power to everything....

I was of the same thought... I thought the cartesian leveli g was still messed up or did something change suddenly? On Jun 3, 2015 2:50 AM, "Bo Herrmannsen" notifications@github.com wrote:

[Wackerbarth]

@epatel -- "But also, trying to be disciplined. Like carefully look over the Pull Request carefully before pressing the button on github."

I am in total agreement. Further, I feel that EVERYONE should submit ALL changes in the form of a PR and have someone else actually perform the merge (at least two sets of eyes)

[BuzzBumbleBee]

@boelle @Wackerbarth depending on the contributors you could use a code review system like gerrit ;)

[thawkins]

@epatel nice app, but not available for linux...... dont have any win or mac machines....

[thinkyhead]

I'm totally new to auto bed levelling, do you think you can update the wiki?

@clefranc Sorry I've been doing a big move to a new city, so just getting back in the loop after many days away. I will do a basic overview page about bed leveling soon. Lots to do in that wiki.

[clefranc]

@thinkyhead Thanks, no rush, I'm 2 weeks away of printer stuff.

[shampine1]

I'm interested in testing! I have access to three printers, all currently running the T3P3 branch on https://github.com/T3P3/Marlin
I'm having a lot of problems with it, so I'm motivated to help! All three printers are running Printrboard rev D with Panelolu2 Emaker Huxley Solidoodle 2 Solidoodle 3 I don't have any hardware for auto leveling.

Please let me know how I can help!

[thinkyhead]

@shampine1 You can test the Development branch at any time, then just report any issues you have with the latest code. We'll work with you (at our convenience) to help resolve them for you and for the community as a whole.

[Wackerbarth]

@shampine1 - But, please, in your reports, if at all possible, reference the last commit that is included in the version of the code that you are testing. "Development" is a moving target and we need to be able to know which snapshot of it you are using.

[shampine1]

I'm compiling using Arduino 1.0.6 and #1938 on the Development branch. It compiles so far!

It looks like we should have a comment in Configuration.h in the Panelou area to remind people to install LiquidTWI2.h like Panucatt has. This note is currently hidden in Conditionals.h.

I think it would be a good idea to modify pins.h in the printrboard area. If you have SD support, you have to move the Y endstop to the "Estop" plug; the Y pins are involved in SD communication. Perhaps:

#ifdef SDSUPPORT
   #define Y_STOP_PIN         37   // {normally 8, must be 37 for SD card support}
#else 
  #define Y_STOP_PIN         8  // 
#endif

I'll upload tonight!

[shampine1]

I'm compiling using Arduino 1.0.6 and #1938 on the Development branch. BTW, thanks for putting the custom name in Configuration! I've adjusted the settings to match my Solidoodle 2 x, y, z, sd and time all show --- on startup The display shows numbers after homing Takes about 4 button pushes the first time before anything happens SD and time show something after you start printing Later it has taken about 10 button pushes; not a fixed number. The therrmal behavior seems different I tripped thermal runaway once on heatup The extruder, bed, and fan on lights don't work when you are in manual control, but they do work in SD printing. Marvin's feet have this weird cyclic stepping thing on the outlines; not smooth at all! I don't know if this is an artifact of some acceleration setting or not. I didn't print Marvin on my previous version of Marlin. The perimeter is a little more smooth. I can feel the printer vibrating slightly when this is going on. Linear infill doesn't have this jerky thing. On the good side, I was pleased to see the menus have improved! I'll let you know what Marvin looks like in the morning.

[shampine1]

Marvin failed. However, I suspect that it is an extruder issue, possibly brought about by the discontinuous motion problem. I'm printing something less oval as a test right now.

[thinkyhead]

Takes about 4 button pushes the first time before anything happens

Looking forward to fixing that soon…

I tripped thermal runaway once on heatup

Bed or hot-end?

[shampine1]

Hot end. I tried Marvin with the acceleration turned down to 1000 (from 3000) and Jerk turned down to 10 (from 20) That helped quite a bit, but I still have the infamous E3D heat soak extruder problem. Groan. I think those settings are too high for most printers. I would change the default to either 750 or 1000 for X and Y. I'm also going to try re-meshing Marvin; that thing has a crazily high triangle count! Anything I can do to help?

[thinkyhead]

infamous E3D heat soak extruder problem

Is that due to the heat taking a long time to migrate from the heating element to the thermistor?

[shampine1]

Scott, No, the E3D hotend uses a large round heat sink with a fan above the heater section. There is a thin stainless steel heat break between them. If the heat sink gets above the glass transition temperature for PLA, the PLA filament starts changing shape (swelling up) and sticks in the heat break and/or heat sink. In my case, this is due to running the printer in a VERY hot environment (my un-airconditioned shop in Houston) and a partially blocked air exit. Now that I finally understand what's going on, I can fix it!

[shampine1]

I'm compiling using Arduino 1.0.6 and #1938 on the Development branch. My re-meshed Marvin printed last night and looks very nice!

[shampine1]

I had a thermal runaway shutdown last night on my Solidoodle 3 running 2474. I'll load the latest and re-try

[thawkins]

Has anybody tested the dual thermistor mode, where it uses an extra thermister to spot runaways.

The only time i have lost an extruder was a jhead where the thermistor detatched from the heatblock, so it was feeding back a low temp reading. It melted down the PEEK barrel and the nozzel assembly now at about 350c dropped into the print.

I think having the second thermistor in would have stopped that.

After looking closely, it actually did what it was supposed to do! I found out that my extruder thermistor had gotten unplugged!

[AnHardt]

@thawkins The last time i tested (Mai) dual thermistor mode worked fine. The code is so simple - there can't be much errors in. Just use the first thermistor as usual, Test if the second thermistor is closer than MAX_REDUNDANT_TEMP_SENSOR_DIFF to the first. If not throw an error and kill the printer.

[shampine1]

Has anyone else noticed that Marlin runs REALLY rough when printing short segments? It looks like its stopping between segments rather than following its maximum acceleration/jerk.

[Nandox7]

Yes I believe I've seen that happening. I have a STL that was created from a CAD file that was full of splines, despite the fact that most of the lines are almost straight when printing the movement isn't smooth and the printer kinda stutters. I suspected it could be that and wanted to make a sample part to test it.
