Hi there is a very dangerous behaviour with userposition and machine position.

I have WCS Z offset (G10 L2 P1 Z40) to avoid collision because I can change the height of my build plate.

When I ask the machine to go the position in a macros for ex
T0
G90
G0 Z50

The machine goes well to the userPosition Z50

But if have the same command on the start.g or mesh.g

the machine go to the userposition Z10

In a macro or in the terminal, when you ask for a G90, the machine moves in userPosition, but in start.g and mesh.g the machine moves in machinePosition.
it's only for the Z axis.

@OwenD is it possible to use it with visual studio code ?

Hi,

Since I have switch my heat chamber in duet1XD output I have tge following problem

Error: Failed to switch off remote heater 4: 

config.g for the heating chamber

;Heat chamber

When I have the message then emergency stop

The problem occur even when the machine doesn't print.

Using MB6HC + 1XD
firmware 3.4.6

Thanks !

@dc42 I have tried the 3.5.0 rc2 but the problem still persist
as you can see in the picture :

When I turn the machine in open loop mode I don't have problem when I print circle

@dc42

I have tried to home the axis with d0 d2 and d3 with the same results

The encoder have 450 - 650 mm maximum cable length

@dc42 @Phaedrux ?

@dc42 perfect, I just need to follow the instruction from this page : https://docs.duet3d.com/User_manual/Machine_configuration/DSF_Other

or this is an other procedure ?

@dc42 this is the usb port :
1 x USB 3.2 Gen1 Type-C OTG port
2 x USB 3.2 Gen1 Type-A ports
2 x USB 2.0 Pin header

The otg can use host capability ?

@chrishamm something was done for tinkerboard 2 ?

@dc42 the problem come from the firmware or the motor ?

Megnetic encoder like this one : https://www.omc-stepperonline.com/fr/nema-17-moteur-pas-a-pas-a-boucle-fermee-65ncm-92oz-in-avec-encodeur-magnetique-1000ppr-4002cpr-17hs24-2104-me1k

Can resolve the problem ?

Thanks !

@dc42 After testing the new revision of the firmware I still have the same probem !

Hi,

I'm using duet 1HCL for use my machine in closed loop mode and I find a problem after lot of testing.

RRF 3.5.0 rc1

1 - When I turn the motor from closed loop to open loop I don't obtain the same mesurement on parts (smaller in closed loop)

2 - When I tried to print circle they are good in open loop mode but not in closed loop mode issue in changing direction

I've tried to tune the motor and test lots of parameters but nothing changed...

I also tried assisted loop mode and have the same results than open loop mode (I don't want to use them for the noise)

I'm using 17HS19-2004D-E1000 from stepper online

@Herve_Smith Thanks for the macro, but with this you need to run tour G32 at each startup of the machine

Hi,

I have a question about saving the bed leveling when you use multiple Z motors.
I have 3 Z motors for my build plate.

bed.g : I'm using something like this

G30 P0 X20 Y20 Z-99999 ; probe near a leadscrew
G30 P1 X100 Y180 Z-99999 ; probe near a leadscrew
G30 P2 X180 Y20 Z-99999 S3 ; probe near a leadscrew and calibrate 3 motors

and
config.g

M584 X0 Y1 Z2:5:6 E4; three Z motors connected to driver 2 (front left), driver 5 (rear middle) and driver 6 (front right)
M671 X-15:100:215 Y-10:190:-10 S0.5 ; position of leadscrew/bed pivot point at front left, rear middle and front right
M208 X-5:205 Y0:200 ; X carriage moves from -5 to 205, Y bed goes from 0 to 200

The question is, there is a way to save the offset calculate by the board and apply the same offset after a G28 for exemple ?

It's to avoid to run the G32 at all the startup of the machine.

I don't want to use G29 to have no Z compensation during the print

Thanks !

@fcwilt Yes, I have just a system to up and down the second tool head

@fcwilt Yes I have two tool heads in the machine

I don't understand where I have to move the G30 S-2 ?

@fcwilt I'm not runing a G30 before each print

The G30 S-2 is to save the tool Z offset in the config-override

And when I'm doing the height map, the bed is well heated

@tom33 I have also tried with

G31 P500 X-30.4 Y0 Z-2.35 ; ```
