Smart effector first layer issues
-
@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
M561andG29 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.Ian

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... -
@Lakeman
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,
-
have you got the link to the ones you printed as there are afew and I found these to be best
Used with the PCB ball mount supplied with the smart effector
anycubic_predator_carriage_SE-PCB_withoutFE.stl -
Link here for flying extruder version also

using the pcb supplied guarantees perfect spacing -
Haydn_Carriage_Adapter_Remix_v4.stl
This is what I used, I will try the stl file you send me, probebly the safest option to use the pcb's. Your second link goes to a tray, not sure what to do with that
-
Make sure that the spacing between each pair of towers is the same at the top, the bottom, and half way between top and bottom from duets website
The spacing between the bearings at the top of a pair of rods must be exactly the same as the spacing between the bearings at the bottom
-
get the linked version with the flying extruder mounting holes easier to mount the extruder
-
Thanks, I print those and try again
-
One thing I did change on my bed was the standoffs under it the blue discs if you take 2 off and measure them mine were way way off in size each to each I replaced them with springs but that was after getting my setup sorted

Hello, I tried printing the parts yesterday (small parts usually work after some fiddling) and halfway a belt snapt, thats what you get after to much tensioning for more precision... But anyway, I changed all the belts to new ones with a metal core which I had as spare, tensioned the same and printed the small parts again, which went easy somehow. So I tried to print the big part to be sure. Perfect first layer without a mesh, just after a quick delta calibration.
No idea what was wrong with the other belts, could not find any problems on them and the were installed correcly and tried several amounts of tension over the last year.
I will install the new mounts for the arms anyway to remove the 0.5mm, but they do not couse the first layer issue.
Thanks a lot for al the help, It was a hardware foult afterall, altough I am still not sure what was wrong with them.
The support on the forum is great, really thanks a lot.
Should I close the thread somehow to show it is fixed? -

thats a big no no. steel belts do not like sharp turns like you have in a delta. they will break and cause problems.
here are some good belts

Interesting, I had to replace a belt on the original predator and I thing it has more then a 1000 hours with a metal belt in 1 tower... No problems

Glad you got it sorted
Mark as the correct answer if your happy it fixed
