differences between manual and automatic leveling
-
Hi Frederick,
maybe it have discribed it wrong in the title. I would like to get the Z height with my IR Probe and then compensate any hills and deeps getting the mesh...I have 4 adjusting screws, and have now leveled on the fly. Looks good now. Mesh is deactivated.
If after this print i will send a G29 then heightmap should be really flat.. Or what do you think?
-
Hello again,
so print is done and looks good, bed sems to be flat!
but why is this heightmap looking like this? It was made directly after the print. I'm very confused
-
@gip_86 That's the movement of your printhead!
Can you mount the sensor nearer to the shafts? That should increase accuracy. -
The heightmap you posted reveals some bed irregularities, which are common.
It also shows the bed is not as level as you would like it.
You can read about using the manual bed leveling assistant here:
When can you update to firmware 3.3 (or later)?
Frederick

Some of your config.g command syntax looks like RRF3 already.
M558 P1 C"zprobe.in" H5 F400 T6000
What firmware version are you actually using?
Can you share the results of sending M122 and M98 P"config.g"?Can you confirm your coordinate system is right handed?
-X should move left, +X should move right
-Y should move to the nozzle to the front of the bed, +Y to the back. -
okay thank you for this information.
I think i can update this weekend. but i'm not shure if it works, because i have tried it befor i have set up the machine abd i always got errors. If i update to 3.3, can i use the old config or should i do all new?
(because i'm not so good writing these files)here is M122, (M98 will follow this day)

Hi,
There are changes that need to be made to use v3 firmware but they are not extensive.
You could use the configuration utility to create a new set of configuration files.
Or you can edit your existing files.
I put off doing it for quite a while but I'm glad I finally did. Version 3 firmware has many good things.
You cannot for from v2.x to v3.3. You have to go from 2.x to 3.0 and then from 3.0 to 3.3.

When dealing with bed mesh, it useful to remember that what we measure is not just the characteristics of the bed but also all the errors between the bed and the sensor, including x,y,z mechanical system, head errors (e.g. does it sags and tilts) and error nozzle and the sensor (e.g. if the head tilts) and sensor errors (how accurate it is, is the bed surface compatible with it, etc).
That's why we sometimes see measurement results that wouldn't make sense if we would measure the bed alone.
Having some experience with HEVO, and it's motion mechanism tends to be soft (compared to more modern extrusion+rail based designs), especially the X rods, which are thinner (8mm?) and sag or cause head tilting. I would suggest to place the sensor to have zero y offest rather than zero x offset since this will cancel better the effect of head tilting.
BTW, do you use two independent drivers for the Z motors? If you do, the Duet can do auto 'real' leveling between the two motor which is nice and reduces the compensation that the mesh need to do.

Updating to 3.3 isn't that hard really, but it can be confusing if you're really used to the RRF2 way. I do recommend updating though, 2.03 is ~2 years old.
If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them first. Reboot after each. Use M115 in the gcode console to verify the firmware has been applied.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip
That will get your firmware and DWC up to date.You can see the change logs here:
https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.xFor your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.
https://configtool.reprapfirmware.org/StartBackup your existing config files in the sys folder in case you want to switch back to RRF2. It’s easy to switch back and forth, just upload the zip file for the version you want and then upload your config files.
These documents will come in handy during the conversion.

ufff spent the 4 last hours to upgrade to 3.3. holy sh... nothing was working anymore. had to switchover to bossa.
Now it works ok. but i get a heater fault. i will try to compare to my old config

If you copy-and-paste your new config.g file here (using the </> tag) we can all pitch in and take a look.
It's very likely just a syntax error.

Hmm...
Everything seems correct.
When are you getting this fault?
What is the exact message your are seeing?
Thanks.

hi Frederick
this is the message i got:
Error: Heater 0 fault: temperature rising much more slowly than the expected 1.3°C/sec
Resume state saved
Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault -
@gip_86 Have you run a PID tune of your extruder and bed?
-
yes i have one done for the heater and the bed.
Bed:
Warning: heater behaviour was not consistent during tuning
Auto tuning heater 0 completed after 4 idle and 25 tuning cycles in 5317 seconds. This heater needs the following M307 command:
M307 H0 B0 R0.957 C113.0 D6.66 S1.00 V24.2
Edit the M307 H0 command in config.g to match this. Omit the V parameter if the heater is not powered from VIN.Heater:
M307 H1 B0 R2.746 C97.9:59.2 D5.41 S1.00 V24.2
one question:
after firmwareupdate now it takes very long to heat up the bed. is this normal? -
@gip_86 Have you got a config-override.g in your sys folder with the output of the tuning? You also need a M501 in your config.g if you do.
-
no, i have put the M307 in config directly..

and in config should only M501? -
It's perfectly fine to put everything in config.g
The config-override.g file is just to make it a bit easier as a M500 after certain operations makes the needed entries in config-override.g.
I have never used config-override.g - I move the contents to config.g and delete config-override.g

after pid tuning i have decided to add "R4700 behind the M308.
Now bed has heated really fast. Is there something agains R4700? I had this thing in my old config.
Now it looks like:
M308 S0 P"bedtemp" Y"thermistor" T100000 B4400 R4700
M308 S1 P"e0temp" Y"thermistor" T100000 B4400 R4700
