Just spotted the answer in the doc''s, yes the ZB connector needs to be jumpered.
I have the need to pause a lengthy print.
Since I've never done this before I was wondering what the process for implementing it is. Do I simply "Pause" the print and shut down the printer and laptop?
I assume I should home the machine before restarting? How does it know what line of code to start from when I fire up the printer again?
Any "how-to" would be great if there is one..
After homing, assuming I'm using -.01 as posted above my control panel shows Z at -0.1 that assumes a deflection of the piezo if I understand you post correctly. The -0.1 is then adjusted based on baby stepping and printing of the 1st layer and ultimately could be less or more and that actual number should be reflected in the config.g file, correct?
So in Slic3r I need a Z offset that reflects that actual number +/-… I think I understand.
One additional follow up question on setting the Z axis positioning.
[c]G31 X0 Y0 Z-0.1 P600[/c]
If the piezo is effectively able to find Z=0 then why the need for an offset in the config.g file? Is this to force the probe to go below the bed surface?
When the probe touches the bed surface shouldn't that effectively be the Z=0, no offset is needed from that point forward?
Thanks for the quick feedback DjDemon.
I ran a first test with the unit and it seems to be working correctly.
In my homing files (homez/homeall) what would that look like now, something like the following?
G91 ; Relative positioning G1 Z-350 S1 F300 ; Move Z down until the switch triggers G1 Z2.5 F300 G1 Z-5 S1 F150 ; Move Z down until the switch triggers G1 Z2.5 F150 G90 ; Back to absolute positioning G92 Z2.5 ; Tell the firmware where we ar
G91 ; relative mode G1 Z4 F200 ; lowers bed 4mm to avoid dragging nozzle over the bed G90 ; back to absolute mode G1 X150 Y150 F4000 ; put head over the centre of the bed, or wherever you want to probe G30 ; probe G91 ; relative mode G1 Z4 F50 ; move slowly 4mm in the +Z direction G90 ; back to absolute mode G30 ; probe G1 Z2.5 F150 G90 ; Back to absolute positioning
Just wanted to close the loop on this and post my working Z homing file.
