@steveps3 the input shapers are complex beasts designed to cancel out the ringing oscillations you see on your prints. The different types have slightly different characteristics (e.g. targeting a single narrow frequency range, or targeting a wider range but to a lesser extent).

Every printer will have different vibration properties (natural frequencies, damping factors etc) and so there is no sensible way to get a one size fits all solution, and tuning is the only real way of getting the best result.

The suggested approach is to use the accelerometer to identify your printer's resonant frequency(/ies), then use the ringing test print to try the different shapers to see which one gives the best results. Once you've narrowed it down to one or two, you might also want to try varying the frequency a little to see if that improves things further.

A value of about 30 seems to work just fine.

@fcwilt
I think it’s a G29. It is whatever the command is under the compensate and calibrate button.

Got it.

I've seen the button but have never used it - I have my own macros for creating height maps.

Thanks.

@StevePS3 said in Extruder fan permanently spinning:

; Fans
M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency
M106 P1 S0 H1 T45 ; set fan 1 value. Thermostatic control is turned on
; Tools
M563 P0 D0 H1 F0:1 ; define tool 0

Where do you have your fans actually connected?

Your tool has defined fan0 and fan1 as the tool fan. If fan1 is the hotend heatsink fan, then you don't want fan1 assigned to the tool as well.

Change M563 P0 D0 H1 F0:1 to be M563 P0 D0 H1 F0

you can't set the jumper to 5v and use 12v external supply. jumper and vfan needs to be the highest of the two voltages so in essence you need to set the jumper to Vin and use two buck converters as noted in the documentation

edit: i suppose you could use the 5v pin from the vfan selection header, but the jumper needs to be on Vin.

Glad you got it sorted. I'll add a note to the page about adding the jumpers back to the second Z driver port as it certainly may not be obvious to the uninitiated.

By the way, if you already have a probe you don't really need to use the dual z endstop method at all, but if it's working for you, rock on.

It is a funny story. I don't know how but my setup changed from a CoreXY to being Cartesian. So when I told it to move it was only turning 1 stepper at a time. I am still totally in the dark as to how it happened.

Well good new. I decided to totally scrap my install and I went back to the configurator. After going through the process a couple of times and tweaking the settings, by BL touch is working again.

There is probably a good lesson to be learnt here, especially for someone just getting into reprap firmware. Don't tinker with the config any more than is absolutely necessary. It is much better to use the configurator.
