I realise I was asking unconstructive qns, about the Nxxx and *X represent. pls ignor that.

I went back to do the Z-offset cal again, after selecting a new z-offset cal, and hitting set butt, the followings are the g-code ack outputs

C: M105
R: ok T:214.4 /0.0 B:89.9 /0.0 T0:214.4 /0.0 @:0 B@:0
C: M851 Z3.71
C: M500
C: M851 Z3.71
C: M500
R: echo:Z Offset: 3.71
ok
C: M105
R: echo:Settings Stored
ok
echo:Z Offset: 3.71
ok

so I guess M851 Z3.71 is to set a new z-offset and M500 is to save it to eeprom
I read somewhere in this community also, that the higher the Zx.xx, the closer it will bring the nozzle towards the bed.

The Z bed leveling must be done at the beginning of each print. Use gcode g29 in your repetier host start script after g28.
Exact instructions:

I issue M851 to my press afew times, it echoed different output all the time, except that Z Offset always show 4.01
anyone knows what Nxxx and *X represent what thing?

19:42:34.500 : N116 M851 *9
19:42:34.500 : echo:Z Offset: 4.01
19:43:13.843 : N153 M851 *8
19:43:13.843 : echo:Z Offset: 4.01
19:44:16.234 : N211 M851 *13
19:44:16.234 : echo:Z Offset: 4.01
19:44:37.046 : N231 M851 *15
19:44:37.046 : echo:Z Offset: 4.01

If the Z offset is setted near or at 0.00, will it bring my extruder nozzle closer or away from the bed?

I'm pretty sure it saves it to firmware... If you keep the "printer settings" open while running the calibration, you can see the Gcode to verify.

is the z calibration a firmware setting or is it stored in soliprint? That is, if I do the z-calibration in soliprint, will it have any impact on a print using Repetier-Host?

Go to the Press getting started page on the Solidoodle site for info.

I agree with cptskippy, getting the z calibration right is very important for the z probing at the beginning of the print to work properly. Tweak the initial bed height position.

As for first layer height, that is in the slicer settings.

Have you run the Z-Offset Calibration Utility?

How on earth with 'soliprint' do you change the first layer height? It goes through the Z alignment, but then when it prints, its set so thin that all it does is back up the extruder.

I want to like this printer.. I love my SD2, SD3, and SD4. (I event like my RapMan3D on occasion)

Anyone?

Thanks.

I like Repetier, but Im trying to give this Soliprint a fair shot.
