Duet 3 mini 5+ wifi sensorless homing - Help
-
Hey Guys I am trying to setup sensorless Homing on a Voron 0.2 . I can get X to home but Y only home when I click on Home Y, It does not work with Home All.

@Karim you might find it easier to create your home x,y,z macros first a d in home all just call the macros in your home all like below
;homeall.g
M98 P" homex.g"
M98 P" homey.g"
M98 P"homez.g" -
@moth4017 ok really never made a macro.
-
This post is deleted! -
someone beat me to it here is my home.g file

@moth4017 ok did that now X home then Z home then Y home. Before X Y Z in this way.
-
@Karim im not sure what type of printer you have but you will need to do the homing in the sequence you require.
eg. X Y Z
-
@moth4017 this is a corexy voron O.2 . This is first time setting up sensorless homing. So really don’t know if homing is working right.
-
@Karim do you have sensorless homing working on x and y yet?
-
this is what i have on my duet3 mini5, your need to reconfigure the steppers and current and travel speed for the voron

@moth4017 yes I have X & Y it working. But it still need tuning.
-
@Karim Hey guys does belt tension have anything to do with sensorless homing.
-
@Karim I've not found that belt tension makes much difference
-
@moth4017 ok,
I am having Y stall sometime when homing.M915 X S0 R0 F0 H200 ; Sensitivity 0 [-64 --> 64], R - take no action, F - No filter, 200steps/sec M915 Y S2 R0 F0 H200 ; Sensitivity -5 [-64 --> 64], R - take no action, F - No filter, 200steps/secSo I find changing the S value in Y makes it move. is that the right way of fixing it.
M915 X S0 R0 F0 H200 ; Sensitivity 0 [-64 --> 64], R - take no action, F - No filter, 200steps/sec M915 Y S2 R9 F0 H200 ; Sensitivity 9 [-64 --> 64], R - take no action, F - No filter, 200steps/sec -
its kind of a balancing act between the motor current , speed and s value ,
it took me quite a while to get them reliable , for some reason i found the tmc2209 and more difficult than others to get reliable
-
@Karim if it tends to stall at the start of the homing move then you probably need to reduce the acceleration of that axis when homing. Recent versions of RRF support command M201.1 for this purpose.

@Karim Just following up on if you got it to work, I've got to do the same thing for my v0.1, I'm upgrading to the v0.2 as well.

@blt3dp I am still testing, it still random stall when homing.

Ok Guys so My XY homes ok, but I have this problem every time the printer first power up and I try to home all Axis, X axis would not move, but I can home X along and it work ok. After I have a successful Home all the problem goes away till power off and on printer the it starts again.

@Karim hi i had this issue too so i just increased the current a little on the axis that stalled
