Just done my first print and the layers are not sticking together it is like there just layers of string. I have checked my extrude length and nozzle hight from the bed I am printing at 205c hotend and 70c heated bed [attachment 54406 IMG_0569.JPG] Thanks Nikki https://reprap.org/forum/read.php?262,507230,507230#msg-507230 Sat, 12 Sep 2026 01:36:36 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,507230,507614#msg-507614 https://reprap.org/forum/read.php?262,507230,507614#msg-507614
the measured steps per mm in marlin 430

measured 50mm

extruded 30mm

measured 21.87

after calculating it i think it is working out at 589 steps per mm is that correct ?

In your first photo was that a flat print (orientation) of just a few layers or is that a tall single wall (with the edge on the bed)?

I will assume for now it is a flat print of a few layers. If so then you are not extruding enough plastic or the nozzle (Z axis is too high). If it's sticking to the bed fine then it's likely the extrusion is off a bit. Adjust the extrusion multiplier up a bit (default is "1" set it to say "1.1 or 1.2"). Then test again.

As for stringing, that is normally an issue with "retraction" either it's off or set too low. A good starting point is to set it to 2mm or 3mm and see how that works for you.]]> tmorris9 Printing Sun, 10 May 2015 20:02:59 -0400 https://reprap.org/forum/read.php?262,507230,507486#msg-507486 https://reprap.org/forum/read.php?262,507230,507486#msg-507486 [attachment 54450 IMG_0572.JPG]]]> Nikki81 Printing Sun, 10 May 2015 18:10:41 -0400 https://reprap.org/forum/read.php?262,507230,507245#msg-507245 https://reprap.org/forum/read.php?262,507230,507245#msg-507245

- Extruder not calibrated or incorrectly calibrated, and you are under-extruding

- Incorrect thermistor parameters set in your configuration file, so the temperature is lower than you think

- Excessive print cooling for the print speed you are using. Try printing slower or with less print cooling (NB print cooling is separate from hot end cooling - many types of hot end require permanent cooling from a fan).]]> dc42 Printing Sun, 10 May 2015 05:57:56 -0400 https://reprap.org/forum/read.php?262,507230,507230#msg-507230 https://reprap.org/forum/read.php?262,507230,507230#msg-507230
