@phaedrux I hadn't seen them; I'll start using them straight away. Thanks again!

I've come to the conclusion that the filament I was using was simply terrible filament. I've stopped printing the model I was trying to (1st pic below) and have just taken delivery of some Filamentum Extrafill PLA which has shown absolutely no stringing whatsoever with your settings. The 2nd pic is the temp tower test I did (literally the very first print with this new filament)

Note: I did dial down the retract speed for the first print 7200 -> 2400. I am new to this filament and not being familiar with it led me to lower the retract speed until I learn more about its viscosity. I didn't want it snapping with high speed retracts.

Looking at the 2nd pic suggests to me that I need to introduce some negative R values as the point after a retract seems to over-extrude a bit. The whole print is generally over extruded but that's the next task now I know the print temp..

@mloidl Yeah, this would be a good compromise in the short-term. Thanks

Check that the trigger height of the bltouch remains constant when you probe the bed multiple times in the same spot using G30 S-1. If it doesn't, then you may need to reduce the probing speed (F parameter in the M558 command).

@hergonoway Ok, will play with microstepping after then.

I have had no end of problems with this Flexion extruder. Bought it about 4 months ago and the stock mk8 extruder gave me significantly better results.

Do you think I should be able to return it?

Mesh bed compensation won't be used unless you invoke G29 or G29 S1 to enable it. So it doesn't need to be disabled, just don't enable it.

All working now, thanks again

Because the firmware assumes that any drivers of the 12 supported that you haven't assigned explicitly areused for extruders.

@Drammy:

When performing a bed execution I get the following error followed by a load of triangle interpolation toast messages…

[[language]] Version: 1.21-RC4 Message: Uncaught SyntaxError: Unexpected token W in JSON at position 108 URL: http://192.168.0.9/# Line: 3:1 Error object: {}

upon interrogating the response the value shows:

[[language]] Bed equation fits points [60.0, 25.0, 0.062] [60.0, 125.0, 0.317] [175.0, 125.0, 0.400] [175.0, 25.0, 0.202] [100.0, 100.0, 0.293] Warning: Triangle interpolation: point outside all triangles!

We recommend mesh bed compensation (G29), not the 5-point bed compensation you are using.

OK, so I've altered the home files' G92 commands to Z0 and it has worked well. Phew!

@dc42: thanks for pointing me in the right direction. (great board btw)
