New experimental firmware 1.19beta10
-
Auto Delta Calibration just went all wonky in beta 10.
Head moves all over the place, eventually makes it to the probe point, then moves to the next one, sort of.
Here is a YouTube video showing what I mean -I think this has to do with
Probe deployment and retraction for G30 and G29 commands is now handled automatically. You should still include a M401 command before the first G30 command in bed.g and a M402 command after the last one, so that the probe deploys and retracts once for the entire sequence instead of once per G30 command.
I would try emptying deployprobe.g and retractprobe.g if it's not needed
Will give beta 10 a try when I get home tonight. -
Hi mine is doing this also, and I don't have a deployable probe or a deployprobe.g ot retractprobe.g file at all.
Back to beta9 for now I think.

To those of you with delta calibration issues: read the upgrade notes.

Lars, thanks for trying the leadscrew adjustment. To help me diagnose this, please do the following:
1. Create a copy of bed.g as a macro. In that macro, replace S3 on the last G30 command by S-1.
2. First run the macro, then G31. Repeat until the corrections are out of range. Post the output.
-
Fixed thank you. I did have deployprobe and retractprobe macros.
However since we all know few if anyone reads the release notes, maybe that one could be in the original post above since it will affect almost everyone. Just saying realpolitik and all that.
-
So if I understand this the probe (if implemented) will deploy/retract with each G30 command?
If that is correct what is the purpose.
Thanks.

It will only deploy and retract if it is not already deployed. So the behaviour is unchanged if you have M401 near the start of bed.g and M402 near the end.

I'd agreed for a stable release but I think most people beta testing actually reads the release notes. I do.

OK understood.
Under what circumstances would you want the probe to be deployed/retracted with each G30/G29 command?
Thanks for the reply.

I believe it is to avoid the probe not being deployed when executing G30/G29 as a single command
If you are doing bed compensation with multiple G30, you should use M401 M402 -
Just installed beta 10, seems to be having a problem when showing the heightmap.
After calibration, the heightmap overlay appears, but it's empty
If I choose Show Mesh Grid Heightmap under Auto Delta Calibration the browser won't response and needs to restart.
Now sure if it's the problem with RRF or DWC 1.17+1.edit: it seems to print normally, will look into it later and provide the config and bed files for investigation

No need to look into it. I forgot to warn chrishamm about the change to the height map file to support different X and Y spacings. We'll have to wait for him to do a DWC 1.17+2 release.

If you are doing bed compensation with multiple G30, you should use M401 M402That's right. Several people complained that G29 didn't deploy the probe automatically.

Thanks David for the quick response

I have just released DuetEthernetFirmware1.19beta10+1. The primary reason for this release is that on some Duet Ethernet boards, it was not possible to flash new firmware using the web interface or M997 when a recent 1.19beta firmware version was installed. AFAIK this only affected the Duet Ethernet, so I have not released new binaries for the other Duets.

Lesson learned.

I just tried tuning the heaters, my E3D V6 with 30W heater got this result:
Heater 3 model: gain 454.8, time constant 203.3, dead time 5.0, max PWM 1.00, mode: PID
Computed PID parameters for setpoint change: P15.9, I0.078, D55.9
Computed PID parameters for load change: P15.9, I1.103, D55.9pre-beta 10 result:
M307 H3 A465.8 C207.5 D7.0 S1.00 B0However it failed to tune my heat bed on first run:
Auto tune of heater 0 failed due to bad curve fit (G=59.2, tc=65.8, td=0.0)one second run it got
Heater 0 model: gain 53.4, time constant 52.2, dead time 1.0, max PWM 1.00, mode: PID
Computed PID parameters for setpoint change: P177.6, I3.406, D122.1
Computed PID parameters for load change: P177.6, I58.798, D122.1
The 2 blue peaks are from the heat bed PID tuning, look similar to me
The yellow peak is the heater after new PID tuning, look AMAZING -

I take it you mean G32 not G31…

Thanks Lars, that gives me something to look at. You are probing close to leadscrews 2,0,1 in that order, so we would expect the corrections to be close to the height errors for points 1,2,0 in that order. They are:
Height errors in order 1,2,0: 0.152 0.078 -0.287
Adjustments: -0.229 0.135 0.409So the corrections look way out. I'll check and simulate the maths.
Which variety of Duet do you have?
