New experimental firmware 1.19beta8
-
Wanting to test the "fixed" pressure advance feature, I upgraded my Duet Wifi from 1.18.1 to 1.19beta8.
Now if I want to run mesh grid compensation, I get this error (this worked in 1.18):
"Error: No valid grid defined for G29 bed probing"
I have an i3 clone with NPN inductive probe, here are the relevant parts from my config.g :
; Movement section
M208 X200 Y298 Z200 ; set axis maxima (adjust to suit your machine)
M208 X-3 Y-20 Z0 S1 ; set axis minimum (adjust to make X=0 and Y=0 the edge of the bed)
; Z probe section
M558 P4 X0 Y0 Z1 H3 I1 F300 T6000 ; NPN invert used for homing Z axis, dive height 3mm, probe speed 300mm/min, travel speed 6000mm/min
G31 X4.25 Y0 Z0.87 P500 ; Set the probe height and threshold (put your own values here)
M557 X1:180 Y1:290 S30 : Set probe gridI also had initial problems getting the duet connecting to my AP. After I initiated a new SSID and simple password (original pwd had a @ character in it) it began to work.
-
That looks like it should work. I wonder if the issue is the X probe start area is outside of where the probe can reach (+4.25 offset on X vs -3 axis minimum).
Maybe try 5:185 for the X probe range in M557.
-
You can run M557 with no parameters to check whether the grid was accepted. Or send that same M557 command manually from the GCode Console, and see if there is an error message.
-
Manually sending M557 works but now I have to set X5:185 or else I get warnings during probing:
[[language]] 4:24:08 PMWarning: skipping grid point (1.0, 271.0) because Z probe cannot reach it 50 points probed, mean error 0.099, deviation 0.110 Height map saved to file heightmap.csv 4:23:56 PMWarning: skipping grid point (1.0, 211.0) because Z probe cannot reach it Warning: skipping grid point (1.0, 241.0) because Z probe cannot reach it 4:23:42 PMWarning: skipping grid point (1.0, 151.0) because Z probe cannot reach it Warning: skipping grid point (1.0, 181.0) because Z probe cannot reach it 4:23:28 PMWarning: skipping grid point (1.0, 91.0) because Z probe cannot reach it Warning: skipping grid point (1.0, 121.0) because Z probe cannot reach it 4:23:15 PMWarning: skipping grid point (1.0, 31.0) because Z probe cannot reach it Warning: skipping grid point (1.0, 61.0) because Z probe cannot reach it 4:23:01 PMG29 Warning: skipping grid point (1.0, 1.0) because Z probe cannot reach itThis makes no sense to me, are the M557 coordinates extruder coordinates or probe coordinates?
If I reset the duet and send M557 to the console I get message "Grid is not defined".
I tried moving the M557 line as the last line in my config.g but it does not work.
Mind you that this worked flawlessly in 1.18.1 -
actually I have a typo in my config.g, my probe sits 4.25 cm to the right of my nozzle.
So the correct G31 command is G31 X42.5 Y0 Z0.87 P500so taking this into account, I should be able to probe absolute coordinates X0:137.5 and Y0:290, so this means the probe will be at positions X42.5:X200 Y0:290, right?
-
It works the other way round. The grid specifies where you want to probe. The lowest X value that the probe can reach will be the minimim X set in your M208 S1 command plus 42.5mm.
I added the warning messages in the most recent beta, because too many users have been asking why it doesn't probe all the points they asked for.
-
Thanks that makes sense.
It would be nice to mention this in the GCode M557 wiki/Mesh bed compensation wiki as this leads to confusion
-
I updated from 1.18.1 to 1.19beta8 last night…. running mesh bed compensation completes correctly but does not load the visual after just gives and error about not being able to find the heightmap file.... but I can click view on the file just fine and it opens after.
Also I have to jump on the bandwagon of people who are constantly disconnected from the DWC. It happens randomly when I click things and if I am away for a few minutes.
Everything is also very slow and laggy now.... clicking anything there is a lag a pretty large one.... I can probably count 10 to 15 seconds before a jog button click or config file open responds. My printer is currently 5 feet from a high end Asus wireless router

Testing IDEX on beta8 and when I change tool, the "new" tool moves to the position of the old tool after running my post.g code.
This means that the heads collide and the new tool looses position.
I could post all my config, but I don't want to clutter the post. Let me know what parts you are interested in.

@Kulitorum, don't you have your tfree#.g files set up to park the old tool?
-

Ok, so if the head is moving to the position of the old tool, which position is that? The position before it ran tfree0.g, or something else?
-
It moves to the park position of the old head.
PS: Can you change the 60 sec between posts? - Seeing this for the third time today….. Also the 30 sec between searches is annoying - if you did not find what you were looking for, you can't re-search for 30 secs.
-
I can guess what might be happening. For now I suggest you try starting the tpost file with a G1 S2 command to move the new year to its park position. There should be no actual movement because it should already be parked, but that command should update the desired X coordinate.
In the latest beta you should be able to use G1 R2 at the end of tpost to move the head to the position of the old tool before the tool change.
-
Clicking upload print disconnects me randomly on this build. and it takes a few to reconnect.
-
@dc42 . on the latest build G30 S-1 does not flash a value anymore. Is this a change that i missed?
-
G30 S-1 should still report the trigger height to the device that you sent the command from.
-
DC42,
I am at a loss here on what to do, you have not responded to my comments in a few days.
It makes it pretty hard to do anything
-
If everything is slow and laggy then first establish whether the PC or the Duet is to blame. Reboot both, connect to the Duet from the PC with nothing else running on the PC and see whether it is still slow and laggy. If yes then you have hit an issue that nobody else has reported afair and I suggest you revert to 1.18.2. If it remains slow and laggy then suspect an IP address conflict.
You can configure the number of reconnect retries in DWC.
