I am doing G32 before every attempt.
Ah well just a thought ...about the only thing I have not changed.Cheers

@Carlo your bed.g should have M561 or G29 S2 at the beginning, otherwise it’s probing will be affected by any bed mesh you have loaded.

I always make sure mesh is disabled as per delta cal docs when probing I'm gonna fit the new endstops and try again because nothing is making any difference, appreciate everybody helping at least I have a better understanding of reprap though if I don't get this to work not sure I'll remember it.
Thanks

Hi,
Does anyone know if I can send the board and effector back to Duet to be tested ?
Thanks
-
Not sure if it will be any help, but my full Duet2Wifi config for my predator is here:
https://github.com/nexx/Anycubic-Predator-DuetIt certainly looks like you're too far away from the bed.
On the github, you'll also find the macro's I use, including one I run prior to every first print since power-on.
I'll try and help further when I can, but hopefully this helps for now. The current github is for RRF, but if you go backwards in the history, my RRF2 config is there too.

Thanks NexxCat I started with yours and Jay_uks and your carriage adaptors Thank you for posting them.
It isn't to far away the effector is being lifted away I've tried baby stepping but it just digs up whats been printed honestly after 4 weeks constant not sure there is any combination I have not tried and I'm really not exaggerating
So today the machine is over 6mm shorter than this afternoon according to the calibration? -
Have you checked that the probe is actually returning repeatable values?
Create a macro with the following in it:
G28 G30 P0 X0 Y0 Z-9999 G30 P1 X0 Y0 Z-9999 G30 P2 X0 Y0 Z-9999 G30 P3 X0 Y0 Z-9999 G30 P4 X0 Y0 Z-9999 G30 P5 X0 Y0 Z-9999 G30 P6 X0 Y0 Z-9999 G30 P7 X0 Y0 Z-9999 G30 P8 X0 Y0 Z-9999 G30 P9 X0 Y0 Z-9999 S-1
What does the console report after the macro runs?

Hi,
Results of the macro below.
M98 P"0:/macros/Probe test"
G32 bed probe heights: -0.078 -0.065 -0.065 -0.103 -0.090 -0.078 -0.090 -0.090 -0.090 -0.065, mean -0.082, deviation from mean 0.013
Thanks for help

@Carlo Your repeatability isn't as low as mine, but it still seems well within reason:
M98 P"0:/macros/ProbeRepeatability.g" G32 bed probe heights: -0.036 -0.036 -0.042 -0.036 -0.036 -0.042 -0.036 -0.042 -0.036 -0.036, mean -0.038, deviation from mean 0.003
When you run the delta calibration, are you doing it with the bed and nozzle cold or hot? My macro for calibrating heats the bed to 60C and the nozzle to 130C before it calibrates.
-
@Carlo If you're probing the bed with heaters on, turn them off by adding B1 to your M558 command. To quote @dc42 here https://forum.duet3d.com/post/97669
The reason we keep the heaters off during the recovery time is that some probes (e.g. BLTouch) need to recover from the effects of the magnetic field generated by the bed heater.

@NexxCat
Hi NexxCat,Hot..220c hotend 70c Bed....I'll set the heat as you have mentioned.
Thanks
B1 added Thanks droraft.

Hi,
Results at 110c and 60c
M98 P"0:/macros/Probe test"
G32 bed probe heights: 4.041 4.053 4.041 4.066 4.041 4.053 4.053 4.053 4.053 4.066, mean 4.052, deviation from mean 0.009Thanks
-
@Carlo said in Another Predator:
0.009
That's pretty darn good. Some mechanics (switch and/or overall printer) may do better... but that's a very good number on its own.

That's an excellent result, though I'm curious as why the probe heights are now in the positive and last night they were negative. That offset would certainly explain why nothing is sticking to the bed.
-
Ahh apologies I did change the endstops.... had to the only thing I hadn't changed adjusted the height so now..
M98 P"0:/macros/Probe test"
G32 bed probe heights: -0.196 -0.196 -0.196 -0.196 -0.196 -0.196 -0.196 -0.196 -0.196 -0.184, mean -0.195, deviation from mean 0.004
Better ?
Thanks
-
@Carlo Yeah that looks fine. Hm. What is your current Z offset set to? In config.g you're after the line like:
G31 P100 X0 Y0 Z-0.210
Sorry if this has already been mentioned in the thread, just looking for things at the state of play right now.
-
No that's fine I'll add that in....not sure I want to click upload now don't want to be disappointed ...or cry in front of dudes!
-
Sorry I didn't read that fully Z-0.06

This is the result I think everyone looks and thinks it's too far from the bed but it's not actually completing the print move it's changing direction before it should in the picture you can see where the print does a U turn on it's self so it never joins the print together it just doesn't complete the move almost like the radius is wrong like the circle is smaller than it is I'm watching it and it does not complete the circles or arcs it never makes it to the end it changes direction and doesn't go back to finish it.
Where it has printed ..it stuck and the outer ring is on the second layer but there is a gap in it.. as have all the arcs and full circles they all have a gap in them and relative to the size the outer are bigger gaps than the inner i.e. the further out it goes the bigger the gap.
