Hi Denny,
After more mucking around and a weekend of dissappointing sports (I am an ardent sharks and swans fan) and printer results I am finally back (with the printer) to where I was before the extruder last time i.e. It will not print anything......
I should rephrase that, it wants to print i.e. it goes through the motions but nothing sticks to the bed!, the material just tends to curl itself into a spidery ball underneath the nozel
??DN?? bed heat? extrusion speed?
I am going to make some notes for myself below, I found last time it helps, please feel free to comment if there is something blindingly obvious that i am missing
> new extruder installed, supplied in reverse configuration by Sintron to the unit it is replacing, reconfigured the carriage and end stops to suit - rehomed to bed / sorted.
[ business card (0.58mm) used for clearance between hot end tip and bed]
[ firmware settings for home
// Travel limits after homing
// #define X_MAX_POS 190
#define X_MAX_POS 200

#define Y_MIN_POS 0
// #define Z_MAX_POS 600
#define Z_MAX_POS 185
// #define Z_MIN_POS 0
#define Z_MIN_POS 0.1]
??DN?? 0.58 + 0.1 should mean the clearance for print start = 0.68 above print bed - need to check, perhaps this is too high
> Extruder tested - temp OK for PLA 185 Deg, 230 for ABS, new extruder now fitted backwards, reversed electrical connections on Ramps 1.4 board to correct extrude / reverse directions - OK
??DN?? In pronterface, the extrusion is at 125mm / min, too fast? too slow?
> Bed temperature tested - ok for PLA 60 Deg, Not OK for ABS 110 Deg (struggles to get to 910 Deg), Heater bed is coveref in kaptan tape, thermistor is taped towards the underside side as advised by Sintron
??DN?? Check output voltage of pwr Supply and adjust accordingly
Denny,
Is there anything that you think I may have missed or should focus my attention on?
