Hello,

I have a silikon heat bed. I use the Duet 3 Main Board 6HC with 48V and run the bed with 230V+ SSR. Unfortunately, the system shows me the wrong temperature, it should show 22.7 °C but it shows 85.3 °C. My filament heater reads the correct temperature (22.7°C).

This is how I configured the heatbed: QWG-104F-3950

@droftarts Thank you very much for your quick feedback and good ideas.

Hello,

I have a delta configuration with 6 axes and am currently controlling the axes with the G1 H2 command. This leads to a backward movement.
Now @droftarts had a very good idea , namely to configure the delta system as a cartesian so that I can omit the H2 command and also control the axes directly.

This is my new configuration file, I put it in an extra folder in sys/
Is it enough that I just pack the config.g in the folder or do I have to zip the complete one. Put the file in there?
When I with:
M505 P"config1"
M98 P"config.g"`
It loads the file but I can't home the motors and it says the P is wrong

@droftarts Oh I like the idea very much.
Is there a G-code command that switches motion from delta to cartesian
Or do I have to create a new config. create file?

@droftarts @jay_s_uk Can I free the extruder command E from the H2 command and run it normally?

G1 X14.7126 Y14.7126 Z-51.0191 U-51.0191 V14.7126 W14.7126 E0.594 F1000 H2```

@droftarts Unfortunately that does not work. When I use H2, the correct movement is performed, but when I don't use H2, the system moves incorrectly.
Or if I omit the H2 do I need to add something else?

When I enter this, the effector moves -140 mm along the y-axis:

G91
G1 X14.7126 Y14.7126 Z-51.0191 U-51.0191 V14.7126 W14.7126 E0 F1000 H2 ; move y -140 mm

With the command, the effector moves in the y and z directions:

G91
G1 X14.7126 Y14.7126 Z-51.0191 U-51.0191 V14.7126 W14.7126 E0 F1000

Without the H2 command, the Z0.0 and U0.1 axes do not move

I have now also tested moving the motors in the coupled state with the G1 H2 command and the movement is just as jerky as when it is uncoupled.

Thanks for your answer but unfortunately that didn't work either.

@dc42
Or do I have to consider something else when I use the G1 H2 command?

Hello again,
Is it possible to give the extruder a different idle factor?
I've tried that but unfortunately it doesn't work. Because then all motors have an I factor of 10%

M906 X1800 U1800 Y1800 V1800 Z1800 W1800 I80				
M906 E1200 I10

@dc42

I set the value for M566 up to 9000 but it didn't help.

So if I move with coupled axes

M584 X0.4:0.5 Y0.2:0.3 Z0.0:0.1 E1.0

everything works fine with a value of M566 1200.
As soon as I decouple the motors like this , the movement jerks a lot.

I set the jerk value very high but nothing changed.
I steer the motors directly with the H2 command.
Can it be that it has something to do with the G1 H2 command?

Hello,

When I let the print head move with the gcode, it jerks a lot.
What can I tune to make it better?

G1 X Y Z U V W H2

Here is a video for a better understanding:

@droftarts

Exactly.
I use this slicer https://layerperformance.com/en

@dc42 thanks that works

@droftarts
I want to switch back and forth between 3-axis movement and 6-axis movement.

Hello

Got my motors paired like:

M584 X0.4:0.5 Y0.2:0.3 Z0.0:0.1

When I decouple my motors from the console with the command:

M584 X0.4 U0.5 Y0.2 V0.3 Z0.0 W0.1 P6
G91
G1 X0 Y0 Z-5 U0 V0 W0 F500.0 H2

Unfortunately, only the three motors for X Y Z move. No matter what value I enter for UVW, nothing moves.

Does that have anything to do with the homing of the motors?

Does anyone have any tips?

@deckingman thanks

Do I have to adjust something like current, ... in the config file for UVW?

For a better understanding, if I have coupled the axes like this:

; Drives
M569 P0.0 S0                                            
M569 P0.1 S1                                            
M569 P0.2 S0                                            
M569 P0.3 S1                                            
M569 P0.4 S0                                            
M569 P0.5 S0                                            
M569 P1.0 S0                                            

M584 X0.4:0.5 Y0.2:0.3 Z0.0:0.1 E1.0

How do I have to name the axes if I want to decouple them or can I name them whatever I want?
Here's an example of how I would do it in a gcode file:

M584 X0.4 U0.5 Y0.2 V0.3 Z0.0 W0.1 E1.0 
G91
G1 X-150 Y-150 Z-150 U-150 V-150 W-150 E0.0 F500.0 H2
G1 X-20.4318 Y-20.4318 Z-1.63587 U-1.63587 V16.7082 W16.7082 E0.0 F300.0 H2
G1 X20.4318 Y20.4318 Z1.63587 U1.63587 V-16.7082 W-16.7082 E0.0 F500.0 H2
G1 X-12.4304 Y-12.4304 Z19.5077 U19.5077 V-12.4304 W-12.4304 E0.0 F300.0 H2
G1 X12.4304 Y12.4304 Z-19.5077 U-19.5077 V12.4304 W12.4304 E0.0 F500.0 H2

Do I have to define the UVW somewhere beforehand in the config or something?
I want that driver:
P0.0 = X
P0.1 = Y
P0.2 = Z
P0.3 = U
P0.4 = V
P0.5 = W

@jay_s_uk @dc42 thanks for the quick help
