duet3d 3.3 delta calibtating problems after fimware update
-
Greatings!
I've recently updated my firmware from 1.2 to 3.3 (yeah, it was a challenge after 2 year of usage)
After the update I have one unsolved problem:
the printer calibrates nicely, builds mesh grid nicely, prints nicely. BUT after reboot it cant make a first layer.
The nozzle touches the bed on one side and has a gap of a few mm on the other side. Never had such a problem before update.Looks like it ignores all the mesh grid and calibrations made. But the the mesh grid is definitely on: "DMs created 83, maxWait 0ms, bed compensation in use: mesh, comp offset 0.000"
That's the result of m98:
M98 P"config.g"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Warning: the height map was loaded when the current Z=0 datum was not determined probing. This may result in a height offset.
Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 298C
Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 681C
That's my homedelta.g:
G91 ; relative positioning
G1 H1 X350 Y350 Z350 F1800 ; move all towers to the high end stopping at the endstops (first pass)
G1 H2 X-5 Y-5 Z-5 F1800 ; go down a few mm
G1 H1 X10 Y10 Z10 F360 ; move all towers up once more (second pass)
G90 ; absolute positioningConfig.g and current config-override.g and bed.g are attached.
Any ideas? Maybe downgrade to some v2 will be ok?
Thank you in advance! -

@ololenok so the first question is do you really have arms/rods on your delta that are 3 different lengths?
i suspect not, which makes this line very wrong.secondly, you shouldn't have G29 S1 in your config as you shouldn't be loading the heightmap until after the printer has been homed.
your endstops are set at being at the lower end, they should be at the higher end. Change X1 to X2 in M574 and so on.

@jay_s_uk
Thank you so much for your reply!-
The rod lengths are the same, but looks like the printer xyz tower distance is not the same (the build is not very accurate, my fault, firs project higher than 70cm). So I've made different rod length in config to compensate geometry while calibrating it with test prints.
-
where should I place G29 S1 to auto-load it each time the printer boots? Looks like it is the thing that's causing the problem...

@ololenok i think you can add your G29 at the end of your homing file (home delta) if you'd like to load the heightmap after every homing...
-
@cosmowave
I'll check it today, thank you.
I just thought it would cause an error since the homing is not finished an that moment (the whole homing script is not finished still and mesh load command is in it) -
@ololenok as @cosmowave says or use start.g or put it in your start gcode after homing the machine

@ololenok said in duet3d 3.3 delta calibtating problems after fimware update:
Warning: the height map was loaded when the current Z=0 datum was not determined probing. This may result in a height offset.
Likely this is part of your issue. You should do a single G30 at the center of your bed to set the z=0 datum before creating your heightmap (I think you missed this?), and before loading the heightmap to avoid an offset.
As the others said, you shouldn't load your heightmap until after the printer is homed etc. If you do a delta calibration with a heightmap loaded, it will mess up the calibration as they two things will fight each other

@engikeneer , looks like the firmware behaviour has changed a lot since v1.21 (it worked fine on that version). Also the config generator gave some very raw results for v3.3, like strange homedelta.g with movements after homing that lead to additional problems.
I'll clean up that mess and test everything.
Thank you for reply.

@engikeneer @cosmowave @jay_s_uk
Thank you guys for your time! Everything is working fine now.
(changed endstop types, moved G29 to start.g, making by hands G30 before mesh grid creation) -

That's likely a result of mistakenly having it set to low end endstops at the beginning.
