Hang printer - Print stops with mesh leveling
-
Hi,
I am trying to setup a hangprinter with a duet3 running duetpi. I have managed to do a few small test prints so the calibration is at least close and it seems to be working. My build plate is a full sized piece of plywood so it is not very flat. I was trying to do a mesh compensation manually collecting the points and the duet interface shows it is captured. Many points are off by several mm which seems correct for the piece of wood and hence the need for a mesh compensation. My test print is a small cylinder in vasemode with a brim. If I run it normally it works. If I add the g29 s1 to the start gcode the print will start as expected but stop as soon as it completes a quarter circle and doesn't continue beyond that. Any thoughts? Thanks! -
Can you share your config.g and your firmware version, etc?

G1 F600.000The procedure I am following is to tighten all the lines up until it is centered over a mark directly below. Then I set that as home. Then I lower it to near the bed and set home again. Double check tensions. Rehome if necessary. I then run a g29 mesh calibration. Try to manually match all points to same offset from bed as the home with a shim. This is usually way off in some points which is not surprising. Return to home and check if it has drifted. If no drift run the print.
If I run this gcode it starts as expected then hangs up after drawing it's first quarter circle. No errors. Web view seems to think the print is still running. It just stops.
If I comment out the g29 s1 it completes the print.
It is not a pretty thing but I can work on that once I know it will run a gcode. And the hang up on with the mesh compensation is very strange. Surfaces we are hoping to run this thing on will probably be even less flat than this as we proceed so we definitely need a mesh to help with printing.Thanks. Sorry again for the delay.

What firmware version? When was the last time you updated duetpi?
Can you try and collect a M122 report when it has hung up? (pun intended)
How are you homing before doing the G29?
Can you post a photo of your heightmap?
-
@phaedrux
I'll grab all that when I can make it over the the print lab.
I have a "set home macro" that I think was a "G92 X0 Y0 Z0", but I will double check it. We are looking to add a bltouch or some other mechanical bed sensor to the printer soon to avoid human error inaccuracies, but there doesn't seem much point if the printer won't run gcode with mesh compensation on.
The motion seems pretty good so far. Doing a dry run of a big 400mm cylinder in vase mode had pretty smooth motion. The goal is to print a part that is about 1m x 1.5m, but gotta get that first layer right first!
Thanks

@shinomori said in Print stops with mesh leveling:
M208 Z-05 S1 ; set axis minima
Does the height map correction exceed 5mm anywhere? I am wondering whether the code to check limits in Hangprinter kinematics isn't working properly.
When the print stops after using G29 S1, does the machine hang, or the board reset, or the print terminate with an error message, or something else?
BTW there are some fixes for Hangprinter in RRF 3.3.

I haven't made it back over to the machine, but on the last test it did not exceed 5mm.
I think the farthest deviation was around 1mm on a 200mmx200mm, 3x3 grid used for that small test print.It doesn't throw an error and seems to think it is still printing because the print duration estimates are moving around. The print head just stops moving. I don't remember if the extruder was still feeding and I think it wasn't responding to the pause print and I had to use the emergency stop. Probably because it thought it was in the middle of a print move and needed to finish that before pausing.
May need to update to 3.3. Are there mayor syntax changes that would require rewrite of all the system files?
Will update when I can make it over to the machine to get info off it.

No, based on your config.g there isn't anything that would need to change.

The last one was just an output of the m122 and it refused it. I had a big post prepared with lots of details. I'll see if I take the M122 out if it works. -
Yes it might have hit the length limit as well.

@phaedrux
I wrote this up while at the machine.Top of M122:

Board ID: 08DJM-956L2-G43S4-6J1F8-3SN6P-9V6QGNow I will tighten the lines with g1 s2 commands: to center it over the dot on the tape.
Then I run my set home macro:
G92 X0 Y0 Z0 E0
G90Use movement keys to position in start location.
Run set home macro again.
Now I run a G29 and get a mesh with a shim.
X0 Y0 is in the middle high one is +.9. Some of this I'm sure is a tramming issue and some jankiness on the printer itself.
Print is only 20mm diameter and first layer is .8mm should be fine for test.
Here it is frozen up timers are jumping around like it thinks it's printing but it is not moving or extruding:

Running sudo apt update and sudo apt upgrade on the Pi should get you updated to 3.2.2 and might give you better results. Much has changed since 3.0
-
@phaedrux Emergency stopped the machine rehomed and ran again. Stopped in the same place, but this time says: M25
Error: Code has been cancelled Think that may be because of attempted pause because it didn't do it the first time.Video of it trying to print.

@phaedrux Got it. Will run that update when I am at the machine again and see if it fixes anything.
-
@shinomori
Ok we ran the update and upgrade on the pi till it showed nothing left to update.Looks like I messed up something somewhere.
Can't connect to duet3.local anymore, but the ip address works.
Showing duet webcontrol 3.3.0 now.
And we're getting this now.
Also getting an "Warning: Incompatible firmware, please upgrade as soon as possible" error on boot.
Does format of the config need to be changed?
When trying to send console commands now the machine keeps getting stuck with the send button spinning and have to restart it to be able to send commands again. Usually get 1 or 2 before it freezes.
-
Ok I was able to get it approximately homed using the console. The freezing started happening less. I tried to simulate the gcode file from before by right clicking on the file in the jobs tab and got:
M37 P"0:/gcodes/Shape-Cylinder.gcode"
Error: GCode file "0:/gcodes/Shape-Cylinder.gcode" not foundI tried just running it with the g29 s1 left in. The screen never changed from above picture so i have no idea what the printer is doing and no control apart from console commands. It did seem to get past the first part of the circle and the height map is still showing so it appears the update fixed the stopping with mesh enabled. Not just to figure out why i have no print control and can't connect via hostname.
