Re: Z home position and stepper full step.
QuoteRoxy For sure you lose resolution. I don't know what happens with the Sli3r's. I know Slic3r moves the Z-Axis in partial steps when it is doing support material. But Marlin will work. I think you...

In the line: #define DEFAULT_MAX_FEEDRATE {300, 300, 5, 25} // (mm/sec) Change it to: #define DEFAULT_MAX_FEEDRATE {300, 300, 2, 25} // (mm/sec) This reduces the feed rate for the z axis. Also for...

Thank you for the quick reply, Stephen. I changed the z max feedrate first, and that did indeed fix the whining problem with the z axis steppers. I tried to do a z home, however, and although the...

QuoteHarvey_S When I decided to add auto bed leveling, I updated to the latest stable Marlin (1.1.0-RC3 - 01 December 2015). One decision that I made (and the source of my problems), is to keep the Z...

It doesn't really matter which way your motors turn. From what you are describing, your printer is moving correctly. The reason it is important to have the correct hand for your coordinate system is...

Use M119 to check the endstop status. The Z may not be working as expected, it should show open when when far away from the bed, and TRIGGERED when the bed or metal object is near it. With...
View ArticleRe: Autolevelling z_probe_offset what is this value used for?
In Marlin setting the #define min_software_endstops false lets you go negative after homing. Z_PROBE_OFFSET_FROM_EXTRUDER is for the difference in the height between the probe and hotend. If you have...
View ArticleRe: Autolevelling z_probe_offset what is this value used for?
Okay so if min_software_endstops is disabled then what does the z probe offset do? Will it lower the head that distance before printing begins? If this is the way it works then I will try it and then...

Stephen, many thanks for your help. z_min endstop was not triggering in RC3, so I went back to Marlin 1.0.2 which was working at one time (except for allowing moves below z = 0, which I presumably...

Update: I may have found the issue. I had uncommented #define DISABLE_MAX_ENDSTOPS, which for some reason was causing Z homing not to function correctly. I commented this back out again, and now z...
