Smart effector first layer issues
ALright, I followed the sequense discribed above, afterwards run a mesh compensation with similar result
Ok add the 2mm back to M665 H run the macro again please then G29
This should be a delta calibration issue I guess. Probably the delta radius or so
We change the height based off of the Z0 yesterday so adding it back to rule that out
Also send M672 see what it spits out
Ran the macro and g29:
Error: M672: No program bytes provided
Run the macro then delta calibrate then G29 sorry Dopy moment here
Wasn't sure it talks back that's fine
Ok. Done the macro again,
Calibrated 6 factors using 16 points, (mean, deviation) before (1.067, 0.643) after (0.000, 0.063)
Diagonals 440.480:440.480:440.480, delta radius 231.706, homed height 420.175, bed radius 185.0, X 0.287°, Y 0.164°, Z 0.000°
Endstop adjustments X0.28 Y0.16 Z-0.44, tilt X0.00% Y0.00%
@Lakeman This is a good page for visualising the effects of the delta (M665) parameters: http://boim.com/DeltaUtil/CalDoc/Calibration.html
I'd guess your delta radius is wrong. Set up and run autocalibration. See https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer
Edit: never mind, you got there!
I entered the values of the delta calibration in the config file, ran the macro and G29:
that looks better notice your radius is some 8mm bigger
I would think about resetting your sensitivity back to default also
M672 S131:131 up to you but I've never seen any benefit to adjusting it with the stock bed
or of a config-override on a delta when you do a calibration before a print
Try a print ? fingers crossed ?
I tried printing after this, no succes...
I will set the sensetivity back and try again
Where are you based in the world ?
Failed again. The weird thing for me is that is is to close at one point, and to high 5mm further. It is so local that calibrition can hardly be a problem. Maybe I should go with an even finer mesh setting, but the original predator did not have a super fine mesh and had no problems at all....
Can you measure the carriage spacing and then effector spacing of the ball joints
or unclip the effector and line it up it to the carriage on all towers ?
If they are fine
Heat bed to 60c 130c hotend home then calibrate Z0.1 see if it goes to that position after calibration.
Not my creation thanks to another user
macro name Prime nozzle also you can add to your start gcode for pla or change the temps for any filament S70 S220 in slicer
So home then delta calibrate first, then run the this macro
; Draw arc to prime the nozzle between 6PM and 9PM on the bed edge
G1 X0 Y-175 Z0.25 F6000
G2 X-175 Y0 I0 J175 E30 F1500
G3 X0 Y-174.52 I174.52 J0 E28 F1500
G1 Z1 E-0.25 F6000
Measured the spacing on the carriages and on the effector: Effector 64.6mm carriges 64.1mm
So there is room for improvement..
@Lakeman On my delta, I've always had issues with mesh calibration. I only use it to check the bed level, then turn it off for printing. When you're doing the delta calibration, is it turned off? Check there's an
G29 S2at the beginning of bed.g (assuming that's where you delta calibration is), then if you do a mesh calibration afterwards, cancel it before trying to print.
Did you change your belts? or tighten them as adjuster is touching the pulley plate so no more adjustment available mine have 15mm ish between them
It seems to be making the same mistake with or without mesh, I just tried a very fine mesh and without after with no succes
But maybe I have to fix the 0.5 mm in the spacing...
would be good to rule it out .5mm when your talking 0.12 -0.3mm layers?
I think ruling it out is the best plan, just not entirely sure if it will work if I just scale the printed parts a bit and hopefully end up exactly 0.5mm wider
I am printing a 0.2mm first layer by the way and I do not know how much effect spacing between the balls has on the height,
