Reset Machine Settings...

[italianmaxx 0]

Well it's now maybe a month I have my UM+Netfabb. I read all, I tried all. Everything working for other Umakers didn't work for me.

I keep on printing with the great CURA+Printrun and so nothing to worry about but...150 euros for netfabb???

after thousand of attempts I was thinking about uninstalling netfabb and say goodbay to my hard earned cash but a last hope: the RESET MACHINE SETTINGS button in the Machine tab of the right menu on netfabb.

This reset all your custom profiles and materials but who cares? never work really good.

after having pressed the miracle button everything simply reset, just 4 materials profile, several build styles. but in the machine tab, under Machine type -Ultimaker menu (the [...] button) and in the ULTIMAKER SPECIFIC code like a magic they appears!

a bunch of gcode lines under the start gcode section. NEVER SEEN BEFORE!!! I had just a m106 and my M92 E14 codes like the masters of ultimakers wisely told me.

this code simply made netfabb work! I use the dreaded tandard material-standard quality setting (it never never worked, never printed something in the first layer).

when I click the print button the head start running and printing 4-5 lines just in the right side, to prepare the print (never done before!) and then suddenly it started to print the 1st layer and so on, FAST, I mean really FAST at 70-80 mm/sec I think, and I got a perfect 20mm cube.

Please excuse my capital letters, it's not a yell, its an alert/warning sign.

TO ALL NETFABB USERS: If YOU HAVE PROBLEMS AND NOTHING SEEMS TO WORK CHECK THE ULTIMAKER SPECIFIC-START GCODE SETTING, IF YOU HAVE NOTHING IN THERE, RESET MACHINE SETTING AND ... HAPPY PRINTING!

So, what's in the header now besides M106 and M92 E14?

Here's mine generated from the NetFabb material editor:

M106 (Fan on)

M109 (Set Extruder Temp 0)

M92 X78.7402 Y78.7402 E14 (set axis steps per unit)

G28 (Move to Origin)

G92 X-105 Y-105 Z0.0 E0 (Set Position)

G21 (Set Units to mm)

G91 (Set to relative positioning)

G1 Z15 (Move table down 15mm)

G92 E0 (reset extrude length to 0)

G1 E15 (extrude 15mm)

G1 E-1 (retract 1mm)

G92 E0 (reset extrude length to 0)

G90 (Set to absolute positioning)

You might want to eliminate the lonely M109 from the header, since it doesn't make any sense to turn off the heater right before the print, it completely messes with the PiD when the next M104 Sxxx comes along

I can't check it right now but tonight i will.

Anyway before I had only M106 and M109. I added the famous M92 E14 but it alone didn't help too much.

Now I have maybe 20 lines of gcode. Like said before the head start a complex routine of pre- printing, moving backleft then farright and printing maybe 4 lines with different width just to prime the extruder then it goes to 100,100 and start the print .

Before that I had several problems:

1- if the 'write some pillar before start' was checked ( in the building style), after the 5 little pillars the head remained high at the pillar exit z and so the pla didn't stitch to the bed/tape

2- if the ' write some pillars...' wasn't checked the extruder start a normal outline raft but very often notihing were extruded and the first layer became a mess

3 -complete incosistency. i mean same object, same gode, gave everytime a different result, mainly a mess...

4 - standard profiles NEVER printed anything

5 - the extruder rpm in the calibration window were totally weird. The rpm for fine and thin settings were about 0.9 but the parameter for medium was about 30 ( all at the same speed)

By the way everytime I start netfabb the demo/full version question appears again and i have to insert again my code. Maybe this could make me think hat something is not going riht with my netfabb...

I think the reset maching setting really reset netfabb with the GOOD settings and profiles that the original installation was missing.

I Printed just 2 cubes yesterday night with different profiles (standard and low) and they went perfectly. I will try more tonight but I feel something has changed in my netfabb. :-)

Thanks Joergen, I didn't catch that. I was wondering why i couldn't print two parts back to back. That might be it.
