Heater Fault and z Stall since the RRF 3.0 Update

M350 X256 Y256 Z256 E256 I0 ; Configure microstepping without interpolation

It's not recommended to use native x256 microstepping. It can limit the top speed of movements and cause pauses/hiccups. Use x16 microstepping with interpolation enabled. This gives the best of both worlds of low CPU overhead and the drivers will interpolate the motor steps to x256 for smooth and quiet movement.

This is unnecessary for the BLtouch. You do not need to manually control the pin. Remove all of the M401 M402 commands. G30 will automatically deploy and retract as needed.

@Donpi said in Heater Fault and z Stall since the RRF 3.0 Update:

The only remaining problem is the Z stall on every layer...

What exactly does this mean? Is it stalling mechanically? Is it just pausing briefly? Can you post a video showing what you mean?

Donpi

@Phaedrux

About my z Stall, the print itself is nearly perfect and there is no mecanical manifestation ( no pause ).

Juste the popup on the panel due or the web control.

I can try to make a little video later in the day, but you would not see anything.

Phaedrux

What does the pop up say?

Donpi

@Phaedrux
Sometimes
Warning driver(s) 0 stalled at Z Height xx.xx

sometimes
Warning driver(s) 1 stalled at Z Height xx.xx

and sometimes
Warning driver(s) 0 1 stalled at Z Height xx.xx

I my printer is a coreXY

Donpi

Now you ask, I noticed that it's never on Z

jay_s_uk

Thats reporting stalls on X and Y then, not on Z

Donpi

I setted the microstepping of all axis to 16 with interpolation ( and changed the steps per mm by the way)

And set my M915 with a bigger S

But I still get the warning

jay_s_uk

how do you have stall detection set up?
what do you have it setup to report?

Donpi

@jay_s_uk

At this moment I am trying with :

M574 X1 S4						; Set endstops controlled by multiple motor load detection
M574 Y1 S4                               		; Set endstops controlled by multiple motor load detection
M915 X Y S5 R1						; Configure motor load detection

And still having the stall popup.

I dont realy whant to disable de report with R0 because this will only hide the problem. (if there is one)

jay_s_uk

Well then you're getting expected behaviour. R1 logs the error in DWC.
You may have to look at retuning your stall detection.
There are a few factors that can be adjusted, such as motor current, The H and S values on M915 etc.
