I have access to the sd Card with FileZilla.
But why i can't bind it as network drive in win 10?

@deckingman said in Difference between M592 and M572?:

@peterfrosta Not quite. M572 pressure advance might be better described as pressure compensation. So what can happen at the start of a print move is that the head moves quickly but it takes time to melt and extrude the filament so the rate of flow out of the nozzle does not accelerate as fast as the print head, leading to under extrusion at the start of a move. Then at the end of a move, the print head decelerates but because pressure has built up within the nozzle, this continues to force filament out, even though the extruder is slowing down, leading to over extrusion at the end of a move. M572 compensates by speeding up the extruder at the start of a move and slowing it down before the end of a move.

M592 is primarily to compensate for extruder slippage. So although the extruder might be turning at the correct speed, if it doesn't grip the filament properly, it can slip. It works by speeding up the extruder in the middle of a move. My advice is to use this with caution because if you don't have extruder slippage, applying M592 will simply lead to even more of a build up of pressure, which will require even more pressure compensation.

To some extent, the two are mutually exclusive, especially when printing at high speed. On the one hand, the extruder might slip requiring M592. On the other hand, if the extruder does not slip, then you'll get a build up of pressure requiring M572.

thx for your fast and good explanation.
M572 is likly i thought. Now, with your words i think i understand M592 too.
Thanks a lot!

I never noticed slipping Filament and M572 eleminate in first tests my blobs pre and post from perimeter at higher speed.
I was fighting against long time. played so much with retraction, E-acc and E-Jerk.
So i'm very happy

Maybe like this?

M572 pressure advance: is for manipulate flowrate at start and end from loop.

M592: compansate the flow at corners for example.

Could this match in approximately?

Could someone explain the difference between M572 and M592?
Both seems to be for handle back pressure in the tube.

Testing the effect from M572 is simple, i got benefits from it.
But i might could have benefits from M592 too.
But how does this work?

Thx in advance!

i got run.

i was not firm with the ne config/gcode that expected from V3.
Unlucky, that the config generator does not import the most settings from my old config.

the problem with movement was the missing inverting from endstops (motor movement was also not inverted as needed).
I tried with line from old config but they doesn't work anymore.

Using new invert style for endstops and i was checking the effects.

M574 X1 S1 P"!xstop"  

thanks to all

heating also not working

Error: Heating fault on heater 0, temperature rising much more slowly than the expected 1.8°C/sec

what's happend with this update process?

ok.
Option 1 ist no option.

I got this warning and same situation about x value (set to -8mm - and no movment)

G28 X
Warning: Obsolete use of S parameter on G1 command. Use H parameter instead.
Warning: Obsolete use of S parameter on G1 command. Use H parameter instead.

If i understand this correctly
https://duet3d.dozuki.com/Wiki/FAQ#Section_I_get_this_error_message_Error_G0_G1_insufficient_axes_homed
i have two options, both need to change the fresh created config from the WebConfigurator,hm...

Option 1:
change in the homex.g

G1 H1 X-405 F2400 ; move quickly to X axis endstop and stop there (first pass)

to

G1 S1 X-405 F2400 ; move quickly to X axis endstop and stop there (first pass)

Option 2:
add "M564 H0"
at the begin of homex.g

Am i right?
