View ArticleRe: Bltouch problem with RC8 and MKS gen 1.4
Just to be clear: Is your BL-Touch in an error state? Because in the error state they report 'Triggered'. Also... One thing that can get them into the error state is not retracting the axis fast...
View ArticleRe: too much extrusion - what to modify in configuration.h ?
Yes... It is the 89 number you want to change. But.... When you change it, be sure to do an M502 to load the 'default configuration.h setup' and then an M500. You should be able to measure how much it...

No, after the power on it does its selftest and expand and retract the pin freely and doesn't blink so I think it's fine. I did a simple test using a mechanical endstop instead of the bltouch (leaving...

Thx, that worked. I commented those out. Now I'm able to use a expander board on aux-2.

You also need to set the correct nozzle size in the slicer so it can calculate the correct extrusion, standard size supplied with most printers would be 0.4
