Hi,
I am currently fine-tuneing my Marlin 2.1.x-bugfix.zip build.
It's the Creality 32 bit board V 427 on the Creality CR-10S5 printer plus Creality BL touch sensor.
I've got several problems and cannot find solutions:
And there is something wrong with the extruder.
During printing every few seconds it retracts for 5 or 10 mm with extremely high speed, then extrudes again slowly while printing.
This results in not printing anything at all, because it again retracts before it extruded the amount it retracted before.
I cannot see any problem in the gcode cura produced. It continuously increases the E-position.
thank you

I've got several problems and cannot find solutions:
- G26 C creates a pattern to test the auto-leveling. But it sends all my clamps flying that should hold the glass to the bed. This is because it prints 5 mm from the edge of the bed. I would like to leave at least 15 mm border. Why is there a "pause for user" after the mesh probing?
- G29 J should check the tilt of the auto-leveling mesh but it does not seem to work. I accidentally moved one of the z axis motors which should have brought the mesh out of tune. After that I did a G28 then G29 J and now the G26 C does not work at all.
- G29 J goes too near to the border as well and sometimes probes onto the clamps which makes the data wrong.
- If I pause a print from the menu, then move the head away to see the print status. Then when I continue to print it just continues where the head is, not where it stopped printing. Is this normal behavior? Can I change it?
- Before Home I would like to lift the head a little so it doesn't scrape over the bed or kick anything that's left on the bed.
- Why does it ask "Click to resume" just after it finished preparation (home and heating) and should start printing? Is there a way to make it beep anytime it asks for user input?

thank you
