Hi Danal,
Pictures as requested,
X0Y0Z1

 5mm below the endstop switches, correct?

Hi Danal,
That's what it's supposed to do but I cant confirm as it homes to the below error so it doesn't bounce.
It used to do as intended but I rolled the firmware back redid the configs via the online tool since these errors.
Note* the height Z-50 is myself trying to move the effector after homing.
Not sure this helps.
Thanks I know its a lot to scan through it is appreciated.

We will get it going. I appreciate your patience in re-posting stuff for the "new guy" looking into this.

@Carlo Your active high endstops are incorrect, should be M574 X2 Y2 Z2 S1 ; Set active high endstops.
It also looks like you have both RR3 and RR2 configs in your config.g ? file -

yes correct, which version of the firmware is being used? as it's confusing

Great stuff homing now works and endstops offsets now look... correct also

Hi Ian,

Thanks

@Carlo can we see your start gcode from your slicer?, you using G32 (calibrate) before printing?, maybe G29 S1 to load the bed mesh?
-
@boldnuts
I have no start code yet having failed to get a layer down yet didn't want to add any complications,
However I have been doing G92 Z0 with paper G32 before attempting aprint ..I never home after probe and always with heated bed and nozzle, bed @ 70c nozzle @ 220c.
I have done the mesh but don't use it .. more to know it's flat..ish I think?? height maps are above in previous post.If that help ?
Thanks
-
You need to run G32 in your start gcode before every print and it might be a good idea to run G29 to load the bed mesh as well, then recall it with G29 S1

YES!
This is one of the big keys to running a delta. Let it find the bed, every time.

I'll try the mesh I do G32 before every print attempt.
dc42 commented a well built delta doesn't need bed mesh so not wanted to ..because I want a well built delta printer
Thanks

Yes, that's great. Very flat. RMS error .027.
You can probably skip mesh, if you wish. I would still run a simple probe before every print to set bed height. They run very quickly, in the grand scheme of things.
Here's my bed.g (invoked by G32 in slicer startup code). Note: The M106 commands turn off (and back on) the hotend fan. Mine vibrates enough to cause false triggers. It doesn't hurt for it to be off for the one minute or so all the probes take.
Build one for you here http://escher3d.com/pages/wizards/wizardbed.php The big key is to do a 6 or 8 factor, so as not to adjust diagonal rod length. (Do NOT do a 7 or 9, at least not before every print). More info here: https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer#Section_Setting_up_the_bed_g_file

I need to try something as mesh didn't work...Did probe then ran mesh then ran probe then invoked G29 S1 and loaded the print file and,
I'll play with the probe G31 Z height a little I guess ? ...changed the print file got sick of the other one.
Also I've just redone my bed file I'll try that first before making any other changes
Thanks -
@Carlo Any reason you didn't baby step down 0.1 or 0.2mm or so? After all this, that would tell you if it's just a probe height problem.
