@kmhudgins If you are using this page to set up :-

this is o.k for a stepper motor with 400 steps per turn eg 0.8 deg , BUT you may have and most likely have a 200 steps 1.8 deg motor , so for a start half than 840 steps per mm

if I remember correct !!
You drop the nozzle down until it touches the bed (bed centre) and zero it out with G92 Z0.
Move the nozzle up again 10mm G1 Z10
and probe with G31 S-1 ? and it should tell you want the bltouch off set should be.

What extruder do you have and stepper motor do you have ?
I would say that printing slow you are just over extruding because your steps per mm are too high or low ( I will have to think about that one), have you set it up for the wrong stepper motor ? eg 0.9deg motor when it`s a 1.8deg motor so if you extruded very slow you would get 200mm.
AND when you try to print too fast your extruder rips into the filament and slips, too much pressure at the nozzle with twice the correct amount.

I just made a quick bed leveling macro .

CHANGE THE home U to home Z , Mine is dual lead screws .

I guess it boils down to , fit the correct rated fuse , check that you have good earth continuity , it is recommended to fit a earth leakage trip and try not to use cable extensions until they have been tested for earth / correct wiring .

I would say to be safe fit a 5 amp fuse for all the printer AND ALWAYS switch or fuse the live side.

I'm using 3dlac , but found now I`m using a heated bed and glass the problem is not getting it to stick , but getting it off the bed without breaking it.
So using bare glass and using 3dlac for the part which left.

I`m using M305 P1 B4725 C7.060000e-8 from e3d's docs is that wrong ?

@msquared I starting using PLA my parts , but started using PETG because I was concerned about PLA bending with temperature, but in the end went back to trying PLA because I had so many problems with PETG being too flexible for parts like the carriage.
I didn't have any problem with PLA until I started to increase the current to the motor and make them really hot.
So what is CF PETG like for part you need to stress like the carriage ?.

@burtoogle said in Nozzle dragging over print:

If you don't do that, it will allow travel moves to cross skin areas without retraction or z-hop

I think that is a part of the puzzle I've been looking for ? , Cura don`t make it simple for you does it ?, I've been looking for some sort of lift while traveling command.
