@droftarts Thanks Ian

@dc42 I am not sure I will be able to do that.
the issue was on the start of the printer and only seen it a couple of times.
sorry

@dc42 thanks a lot for the info.
I think i will give the macro a go
and no I am not using pogo pins - I am using USB cable.
I made a small PCB board to go on the extruder and a distribution board to split can signal into two feeds.
by using USB C 3.2 i think I can supply ennough current at 24V
if anyone is interested I could share the designs

so the question is - is it possible to restart the board without cycling power?
for instance while printing you disconnect the toolhead and the board reports that CAN20 stopped sending signal
then you reconnect the toolhead, so the connection is restored, but the board doesn't see it.
is it possible to reconnect the toolhead without cyucling power?

@Aurimas I understand you're frustrated, but being snarky to those trying to rule out basic things isn't going to get you anywhere here.

I am not frustrated - it has no affect on the machine performance.
I am simply reporting a bug in the firmware - I am not new to the system and I know how to use it.
if it dissapears with restart it makes no difference - the bug is still there even though it is not coming up all the time and it will not be fixed if left like this

@dc42 just yesterday I had that issue, changed the Z minimum to allow negative value and it was printing since.
although it would be difficult to test your suggestion since the error didn't happen 100% of the time or in the same spot.
so my theory would be that if there is some inconsistency in the measurements at different spots of the bed it wants to compensate below minim and that is when it has fits.
It is always in the random spots on the bed (mostly well within limits) and not always - only sometimes.

@Phaedrux said in Ghost can board:

Have you tried a hard refresh of the browser by clearing the cache?

guys, seriously - I am pointing out a bug - ghost can address appears from nowhere
what is the point of refreshing page and/or doing anything to make it go away if it doesn't affect anything
It is not supposed to happen. Period

I don't need suggestion such as restart the printer or refresh the browser

@droftarts All of the suggested kindergarten stuff has been done before asking for expert help in the forum

@droftarts said in Ghost can board:

@Aurimas That usually means there's a reference in your config.g (or other macro) to a board at CAN address 119. I had something similar yesterday.

Object model plugin doesn't take data out of the config file - it scans hardware and reports the data.
but since you insist here is the config file - help youself out
on top of that - today there after powering up there is no ghost board

@eranglr said in Changing Stepper Speeds Dynamically with Duet wifi:

ommand to change the steps/mm for each axis, effectively

segmentation most likely is not going to work since you will ahve jerk and accelleration to take into account.
I have done similar thing before and you have to account for those factors.

3.5.4 version
the board CAN address appears from nowhere.
there is nothing in config or anywhere else.
seen this few times now - after restarts too
the board is listed under machine specifics and object model show the ghost board too. Images attached.
rest of the boards are perfectly fine

@droftarts @T3P3Tony @dc42 is it possible that bed mesh compensation might be creating this issue in the latest firmware versions?
For instance if Z axis min is set to 0 and the bed mesh has to go to -0.2mm or similar - would that throw an error?

@dc42 just as suspected
filament counter is counting correctly anyway.

@T3P3Tony @dc42 it doesn't really affect anything - I am just reporting that there is something in the code that is doing that.
thanks

@T3P3Tony said in Filament drive counting backwards:

t the step counter is overflowing hence

its only 400/mm

@dc42 no sure why would steps matter?
Filament counter reports correctly, while Extruders Drives got inverted mid print
These are two different counters from what I understand and because of that it has software setting issue

@T3P3Tony no - print is finished

@T3P3Tony yes - it was correct to start with.
I am not sure at what point it flipped

@magnets99 said in Filament drive counting backwards:

you could probably lost pla cast a whole engine block with that!

lol. it would depend on the size of the engine block

@magnets99 that is our Vega970
