@jay_s_uk even if nothing is wired the led turned on, I tried with another duet 3 and the same config

Hi,

It will be very usefull to add a backlash offset for the changing direction when we use ball screw for example. All the normal screw have backlash (expect turning and grinding ball screw) so we loose accuracy in cnc use.

Is that be possible to add a backlash option in the next 3.5 firmware ?

Thanks !

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
M308 S4 P"20.temp0" Y"thermistor" A"Chambre" T100000 B4725 C7.06e-8           ; configure sensor 3 as thermistor on pin temp3

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 !
