Linear advance extruder stops

overdrive

hi
I have a weird issue. Trying to calibrate my printer with linear advance fails when L is greater than 17. The extruder gear would just stop moving and the stepper looks to be disabled.

I am runing version 1.03

Extruder steps per mm:299.700
Extruder start feedrate: 10 mm/s
Extruder max feedrate: 70 mm/s
Extruder  acceleration: 10000

Any advise would be appreciated.

Repetier

You should switch to 1.0.4 for linear advance. There were some important changes improving quality with it.

None the less 17 is not much and no reason to stop. I've gone up to 90 when testing the improvements without problems. Do you see any hints in log that it activated e.g. dry run which would disable extruder.

overdrive

Hi
I have now flashed 1.0.4 and no change. the extruder just stops.
It prints the first test line and then prints the first 2 portions of the second test line and just stops the extruder.

Ok, no errors and gcode looks good.
The way it works with advance is that there is a separate interrupt only for extruder steps. The motion will increase a open steps variable and the interrupt will later execute it. In your case the interrupt needs to run with 70mm/s*300steps/mm  = 21000Hz. Timer can not handle this so it gets even 22727Hz. My guess is that this is not enough time so instead of setting a time in the future it happens that the interrupt is in the past making it much slower with extruding. This also causes the extruder counter to overflow so it reverses direction.

So as a first test reduce max. extruder speed to 55mm/s, that is a value which slower moves get increased to, so lower speeds will not help with your values. 

This is assuming you have a 8 bit board. With that there is more time for the interrupt to finish.

overdrive

I have a 32bit board. Changing the max speed to 55 made no difference. 
It gets weirder, if I set L=130, I get a good couple of lines printed of a test cube and the extruder would stop. If I then try to start a print again, my bedleveling would fail immediately. This behaviour looks like a buffer overflow type issue.

Repetier

With 32 bit the 22KHz should be no problem. Overflow makes sense in the meaning that it can cause strange side effects where you do not expect them. Only thing is I'm not aware of any part causing them.

Can you post your configuration. Maybe I can replay it with a logic analyser and then add some tests to find a reason. My configs do not seem to have the problem, but with all the combinations of features there is always a chance that one causes it while I do not see it.

overdrive

Here you go.
I built a custom controller board based on the Atmel SAM3X8E chip, like the Due and the stepper drivers are TMC2208.

/*
If the firmware is in laser mode, it can control a laser output to cut or engrave materials.
Please use this feature only if you know about safety and required protection. Lasers are
dangerous and can hurt or make you blind!!!

The default laser driver only supports laser on and off. Here you control the intensity with
your feedrate. For exchangeable diode lasers this is normally enough. If you need more control
you can set the intensity in a range 0-255 with a custom extension to the driver. See driver.h
and comments on how to extend the functions non invasive with our event system.

If you have a laser - powder system you will like your E override. If moves contain a
increasing extruder position it will laser that move. With this trick you can
use existing fdm slicers to laser the output. Laser width is extrusion width.

Other tools may use M3 and M5 to enable/disable laser. Here G1/G2/G3 moves have laser enabled
and G0 moves have it disables.

In any case, laser only enables while moving. At the end of a move it gets
automatically disabled.
