Calibration Issue

90c bed

I have run through the calibration steps multiple times and feel I have it dialed in. This includes the 4 scripts to level the bed/towers. After each adjustment to EEPROM Horizontal Radius I disconnect in Repetier as well as unplug USB. Plug everything up and bring back to printing temp. Run the scripts again and get everything perfect (as far as I know). I load my thin wall cube test GCODE and slice. I used the manual's ABS slicer profile for slicer. I run the job and the head seems to be well above, maybe .02mm above the bed. I did a test or two and adjusted horiz. rad. to be lower than I wanted. Meaning it was on the bed and not just slightly above it. This seemed to make no difference when re-slicing and and trying the test print again. The head was still too far off the bed to print.

Should I examine Z height settings through the LCD menu and start the calibration process over or is it something in EEPROM, slicer or printer config?

I would think that just setting the Z height via the LCD should work fine. You should not have to do a complete calibration.

Eagle,

I guess my question is how does the LCD Z height calibration effect the 4 script calibration? Something isn't working for me since the 4 script calibration looks fine, but slicing and running a job seems to put the head too far above the print surface. Should I run the LCD Z height again as well as the 4 script calibration? none of the above, a;ll of the above and then throw it out the window? LOL

If you move the head by typing
G1 Z0.2 F3000
How far above the bed does it look to be, if it's correctly calibrated it should be 0.2mm
If that is correct, look at the first few lines of the sliced object, and see what it is setting the Z height to, if it's much larger than you expect, you have a bad setting in the slicer.

Here is my gcode

G21 ; set units to millimeters
M107
M190 S90 ; wait for bed temperature to be reached
M104 S235 ; set temperature
G28 ; home all axes
M109 S235 ; wait for temperature to be reached
G90 ; use absolute coordinates


G92 E0
M82 ; use absolute distances for extrusion
G1 Z0.350 F12000.000
G1 F4800.000 E-7.00000
G1 Z0.550 F12000.000

My bed size in Slicer is 280...don't think that has anything to do withe problem, but does that number seem right? My first layer height is .35 and layer height is .2

I'd like to see a little more of the gcode, but it looks like it's moving to Z= 0.55 before trying to print (though that could be part of a z move during retract). 0.55 is probably too high to get decent layer adhesion, unless you have a 0.7 or larger nozzle.

Basically there is no difference, everything is just sending gCode, whether to calibrate, or jog or print, if when you command it to goto a particular height it's correct, but the slicer is trying to print too high, then there is a configuration problem with the slicer.

GCode looks fine, it's printing at Z 0.35
When you command a move to that height, does it go to the correct height?
