I run a business and I need dependable homing on a machine that will run 20+ hours a day.
Then you can't beat the reliability of a simple switch.
I don't know how marlin sets the sensitivity of stall detection for sensorless homing since it's literally a function of the driver to detect the back emf and stall.
There are examples of working sensorless homing on a corexy. The E3D tool changer uses it for instance. Though corexy presents a challenge for it because of the nature of the dual drive motor setup and the compliance in the belt. The system needs to be rigid to produce a short sharp shock. A cartesian printer with a single motor per axis doesn't have the same issue, so it's a lot easier to tune.
Why it's not working for you, I cannot say. I can only speculate based on what info you've provided. I've offered how I would approach figuring it out.
Perhaps the motors you're using are different than the ones we thought you had?

You can't begin to make things any better if nobody will admit they have a problem.
This is open source hardware and software, if there's a problem, we're all here to solve it and improve it. However, I don't think you've demonstrated there's a problem other than with your setup.
The 2209 and the 2660 are different drivers. Maybe the difference in sensitivity is very different. It's a bit of a moot point since the duet has the drivers it has. Others have gotten it to work without issue, and others have had problems, and yes, a simple switch is usually recommended, because it's cheap, simple, and works reliably.
However, in your case it's detecting a stall immediately, which is the opposite of what you'd normally see as a problem, which is it doesn't detect a stall at all and just slams into the hardstop.

@Phaedrux Please don't be offended. I appreciate your patience and assistance on the issue. As I suggested I recommend the Duet team get ahold of a 32 bit marlin based board so you can see where the competition is at with the feature. A company that feels there safe on top can be caught off guard by a competitor who can identify where the need to improve on their product. Now if marlin was perfect we would never be having this conversation. So all Im saying is there is room for improvement in the tuning process.
And yes my LDO motors do Look a little funny compared to the pics of genuine LDO motors pictured so that could be exactly what makes me feel the tuning process is too complicated if they are a cheap clone that does not have the correct specs. I will reply again when I get to adjusting the leveling points for the BL touch. Hopefully I will have better luck on my own this time around as I did set it up before when I originally had the board on my CR-10 but some of the points were a little off. Again I appreciate your assistance. I just can't spend $1000 of my personal time trying to get senseless homing to work when I have other stuff to get done. -
No offence taken at all. Good luck with the rest of your commissioning and feel free to come back with any questions.

@Phaedrux Im almost there now. X and Y are homing great now and Im on the BLtouch set up now. when homing Z im getting this error now "Failed to enable endstops".
Here is my endstop and z probe setup
; Endstops
M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystop; Z-Probe
M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X-26 Y0 Z2.5 ; set Z probe trigger value, offset and trigger height
M557 X36:290 Y46:290 S48 ; define mesh gridI have tested the probe and it will deploy, retract, and reset as well.
I tried adding M574 Z1 S2 to the endstop lines but the probe failed to deploy
-
most likely are missing the G30 in your homing files and are trying to hit the none existing endstop
post your homing files
-
You need to change your homez and homeall files to something like
G91 G1 H2 Z5 G90 G1 X150 Y150 G30A probe doesn't use the typical G1 H1 moves to home.
That code above basically lifts the bed away from the nozzle, moves to a position (usually the centre of the bed so adjust taking into account your probe offset) and then it proves the bed at that point to set Z to whatever your probe offset is. -
@jay_s_uk Ok that seemed to get me going.
Now I just have to figure out how to adjust where the mesh starts for each axis. the XY max probe points are perfect at 10mm inside the max points of the bed. However the X is starting at 40mm (62 at the nozzle) and the Y is starting at 55mm.

@Kwad3d said in Help me get connected to my Duet2Wifi:

M557 X36:290 Y46:290 S48 ; define mesh grid
If it's starting too far inside the limit, increase/decrease the limits in M557
Try X10:290 Y10:290
To make testing faster, change S48 to P2:2, this would result in a 2x2 grid instead of a full detailed grid. Once you're happy with the extends you can switch back to the spacing method, or increase the number of points.
-
@Phaedrux Thanks. Yea I'm slowly getting it where I want by making those adjustments. Despite my negative opinion on senseless homing the BL touch setup it way simpler and easier than marlin which continuously tried to probe off the bed regardless of adjustments made.
-
@Phaedrux Seems I got the bed mesh dialed in pretty good. I used previous Hight maps to adjust the bed mounting points and this is my result. Sure its not %100 perfect but I will take it. Hopefully that is the last of the assistance I need. Thanks again for your patience and professionalism
-
@Phaedrux So I think Im done setting up the machine. I got a message when sending M500 so save my pid tune saying "Warning: M500: No M501 command was executed in config.g"
Do I just add M501 after the last line in config.g or am I good to turn it off now?
-
@Kwad3d said in Help me get connected to my Duet2Wifi:

Yeah you need to add M501 at the end of config.g to load the saved values at boot from config-override.g.
The saved values are still there in config-override.g whether you turn it off or not.

@Phaedrux Hi again. So I ran into a issue with my bed leveling. When I got the probe grid mapped out for my printer I used the hight map to manually level the bed. I did such a good job that I never noticed that the printer was not compensating for irregularities. I recently changed the build surface and now my mesh is no longer as flat as I posted in the pic. Now Im noticing that the printer is not adjusting the z axis for a good first layer. What to I need to do to turn on leveling based off the generated hight map?
-
The heightmap is not loaded at startup automatically. You need to either use G29 to create a fresh map, or use G29 S1 to load the previously created heightmap. That would usually happen in your slicer start gcode after the axis have been homed (and Z has been homed with the probe).
-
@Phaedrux Yea I have G29 in my start G code but the Z axis makes no adjustments to follow the mesh. Here is my G code.
G28 ; home all axes
G29 S1
G1 Z5 F3000 ; lift
G1 X10 Y10 F1500 ; move to prime
G1 Z0.2 F3000 ; get ready to prime
G92 E0 ; reset extrusion distance
G1 X120 E15 F600 ; prime nozzle
G1 X140 F5000 ; quick wipe- -
How are you determining that it's not compensating?
If you send M122 after the print is started, does it show "compensation: mesh"?
-
I marked my Z motor's 20T gear with a black line. There is no movement other than adjusting for a new layer. I entered M122 in the console and this is what came back

The movement can be very hard to see if you are looking at the gear.
Affix a pointer of some sort to magnify the apparent movement. I use a 50mm nail held to the lead screw with a small magnet.
Once I did that I could see the mesh adjustments.

@fcwilt Its not moving. I have 17 printers in the shop and I can visually see the z axis move when compensating for irregularities in the bed. Also you should be able to feel minor adjustments if you lightly tough the pully on the Z motor as well. I mean I can place a 3mm spacer under the front of the bed where the z is homed to exaggerate a out of level platform to prove its not working but its simply a waste of my time as I can tell its not working. I'm not speculating...
-
M122 indicates it's active. What does the heightmap image look like? Did you re-create the mesh with G29 after changing the bed surface? Do you have any taper off set with M376?
This thread is very long at this point and this is a completely unrelated issue. It might be a good idea to start a new thread with all your config files, etc
