Thanks, that solved my problem!

Hey team,

I'm currently about to upgrade mit MB6HC with SBC from 3.4.6 to 3.5.2 (latest stable).
I executed via terminal:
sudo apt update
sudo apt upgrade

afterwards i tried to update via M997 in the command line, but nothing happended so far:

When i try to execute sudo apt update again, it answers:

Thanks a bunch!

Hey there,

is there a way to reset the password of the user pi?
I do have to reset the fixed IP to set the machine up in another environment.

Thank you in advance
Fabian

@chrishamm thanks, chris!

How can I reset my extrusion factor via a macro (prior to the print start)?

My macro looks as follows:

if move.extruders[0].factor != 1
	set move.extruders[0].factor = 1

i usually get the following error:

Error: expected '=' in line 2 of Reset Speed and extrusion factor.txt

I already experimented with braces and different order - but i didnt get it to work.

Thank you in advance!

@Gordon-Lin
did you get it up and running with the micro switch in the splitter?

@Exerqtor thanks a bunch for sharing! I really appreciate it! Really looking forward to your project

Now i'm back on 3.4.6 and the same crash behaviour happens when executing bed.g via G32, after executing M502 and M500 (or reconfigguring the machine because auf mechanical changes).

I executed G32 with the probe only electrically attached but not mechanically, and the machine doesnt take the 19mm probe height into its calculation, as it travels with the tip of the nozzle to Z = 5 (=0 + 5 dive height)

; Z-Probe
M558 P8 C"^121.io0.in" H5 F300 T18000                            ; set Z probe type to switch and the dive height + speeds
G31 P500 X0 Y0 Z19.0                                             ; set Z probe trigger value, offset and trigger height
M557 R480 S48

After some test and trial with different M500/501/502 combinations with a crash on each G32, I executed G29 Mesh Bed Levelling, which works perfectly fine!

After that first G29 also the Delta Calibration via G32 takes the probe height into calculation and works without crashing.

@droftarts of course, i´m sorry.

The IP-adress entered in DWC i tried with and without the ending "/capture"
Refreshingrates i also tried several 0, 40, 250 (as recommended in DWC or higher), 2000 (standard).
But none of these settings worked.
If i join the Wifi broadcasted by the RaspberryPi with my PC and use my browser i can reach the Cam via its ip (http://10.3.141.100/capture) and get a Picture, but not reliable.

The code i used is pasted in the code box and attached as .txt

Thanks in advance!
