@moth4017
it is a BMG I installed on the LDO motor
they were not purchased as a unit
it is confirmed it is 0.9 degree stepper I get a full rotation when I request 7.7mm of filament which check out at 800 steps per mm with 16x micro stepping the machine seems to be doing whats asked of it
starting to wonder if something is off in super slicer
well unless LDO has a habit of shipping motors that are marked as 0.9 but are 1.8
but I have had good prints with this motor I was hoping someone would see something obviously wrong in my config
I will pull the motor out and confirm rotation tonight
I hate to drag up a older post
but I am noticing similar problems
not sure exactly what firmware it started on I have recently upgraded 3.4.4 from 3.2
I am hesitant to say its a firmware problem but I have been through my config
and I have been struggling since the update
I am going to try this weekend to do a fresh sd card and fresh firmware install
I think I may have had minor problem with this this for a while but since the recent struggles
to get a print resulting in a full hotend rebuild and nozzle change new heat break hot block etc etc
the only thing that seem to help was a 20-30% reduction in extrusion and I probably could go further
its a home built corexy with a bmg duet2-wifi with a LDO 0.9 degree stepper on the bmg
was kinda hoping someone found a solution to these problems above

my esteps are calibrated a little low already I get 95mm when I ask for 100mm
but to just get a print to work I had my slicer extrusion multiplier at 0.89 and my dwc extrusion between 80-90% anything higher would cause massive blobs and over extrusion
ok after a few tries I noticed that it seems to be a bounce I can't see what that board is Queuing but the power macro runs fast enough that I can see the results pretty easy and a quick push
would lead to power on then off where a push and brief hold would result in the expected behavior
I added a 0.1uf cap to each of my 6 buttons I have and it seems to reduced this effect to the point where I can not reproduce it. so here's hoping that is all it was
thanks again @dc42 its amazing the amount of time and support you put in
here
@dc42
well thats entirely possible I read that and misunderstood it or because I have read a ton
lately I am just getting things confused
thanks for clearing it up
I have a bunch more print to get done in the next while so I will keep testing and let you know
I am leaning more to it being bounce and the board is queuing multiple presses
some times it will power on then power off or vise versa when I tap my power button too
this is my trigger2.g file I use for power control
;powerbutton trigger macro
if state.atxPower == true ;if on turn off
M104 S0
M140 S0
M81
elif state.atxPower == false ;else if off turn on

thanks Again for the reply
I have a few buttons attached to my Duet2wifi
and I have a simple macro with a global variable to track weather filament is loaded or not
I recently upgraded from 3.4.2 to 3.4.4 and I noticed a change in behavior
my trigger3.g file
;load unload trigger macro
if global.filamentload = 1
M98 P/macros/unloadfilament.g
M99
elif global.filamentload = 0
M98 P/macros/loadfilament.g
M99
before the upgrade this worked fine now it will load the filament and then right after it will unload the filament
I have 2 theories one is I am getting bounce on the button or the way M99 or trigger files work has changed slightly
here is my button config just in case

M581 T6 P4 S1 R1 ; lower bed 50mm (black) while print is paused (black while printing)
M581 T0 P6 S1 R0 ; estop (red)
I am going to relocate everything from the trigger3 to a separate Macro as it is recommended the trigger files be one line and see if that helps
if we had a "R" option for while print is paused that would be awesome would save some extra coding
anyways thanks
@dc42 thanks I am not a 100% sure where to put that
but I did see a post about adding a resistor to their sensor they were using a different
optical sensor than I am so I didn't think much of it
and as its just a optical end stop I am using there's a good chance I need a better circuit al together
but I will dig a little deeper thanks for direction.
First off thanks for the great forum I have lurked for ages found 99% of answers I need with out posting
I am currently using a duet2 wifi with a duex 5 running 3.4.4 firmware
and everything has just worked for the most part
I have built this sensor
https://www.thingiverse.com/thing:3785514 with a 32 tooth encoder wheel
chosen because I had all the parts on hand. and it is attached to my corexy (sel fsourced railcore) by reverse bowden I would rather not add the sensor to my carriage
here is my most recent attempt to calibrate it

by my math which is probably wrong it should be about 1.2 mm per tooth on the encoder
the designer had his set for around 0.83 mm per pulse
at least this time around the Minimum value seems to be constant now but it is way out there on the max
and the Measured sensitivity is pretty erratic as well
this during a PLA print with relatively few retractions and only 0.6mm of retraction
so any help would greatly be appreciated
