This is what I get if I run the heightmap calculation right after manual endstop and delta radius calibration (Tower X,Y,Z and center are at the same height when at z=0 height). I guess this clearly shows that two of the towers are misplaced. Autocalibration should compensate for this, so, It should be correct to run the mesh grid calculation after running autocalibration (?).by Alu - Printing
I know this might sound dumb, but, mesh grid compensation has to be run after autocalibration , am I correct? I've always done so, as stated on the Duet 3d wiki - but I'm unsure because it's even stated that you should cancel every bed transformation before starting the procedure. The mesh grids i obtain before and after calibration are, obviously, very different.by Alu - Printing
Quoteo_lampe All I can think off is adding height correction to the probe points on the right ( H-parameter in the bed.g file ) and hope it will influence the bed mesh data, too. You could also edit the heightmap file itself, but do on your own risk... That is indeed something I haven't tried after the last build of the printer. I didn't do that because I noticed that when I did that previouby Alu - Printing
Quoteo_lampe I don't use mesh bed leveling on my Deltas anymore, although the XL 35cm bed isn't milled flat either. Your heightmap looks good, did you try to print without MBL? What's your 1st. layer height? I calibrate the printer every day with the probe points in bed.g and thats good enough. Adding a second instance of leveling is only worth it, when the first instance is spot on. Here are sby Alu - Printing
Hi o_lampe, and thank you. Indeed I tried with both MBL enabled and disabled, and best results were obtained with it being disabled. I'm therefore only using the heightmap as a visual reference for seeing what's going on with autocalibration. I tried to print at 0.15mm first layer height until now since my aim is to print in the range of 0.075/0.05 mm - currently trying a dual process slicing iby Alu - Printing
Hi everybody - I assembled a Kossel XL printer with the aid of the beautiful DC42's guide he published on his blog, as well as through reading many of the builds I found on this forum. I had to assemble it and disassemble it two or three times before being able to sort out most of the issues (defective parts didn't help, either). I got to the point where (https://duet3d.com/wiki/Calibrating_a_dby Alu - Printing
Grazie per le risposte, mi ritrovo quindi con 3 rails difettati...andiamo bene. Faccio un tentativo pulendole nei punti in cui si bloccano e se vedo che dan comunque problemi a gennaio ordino gli Igus. Che cosa posso usare per rettificare le guide?by Alu - Problemi e qualità di stampa
Ecco qui, sono riuscito a fare un video. Le prime due torri son quelle che scorrono libere, mentre l'ultima si blocca:by Alu - Problemi e qualità di stampa
Ciao, Appena arrivati gli sliders non scorrevano in modo lineare. Muovendoli sembrava si bloccassero in alcuni punti. Li ho allora smontati tutti, ho tolto tutte le palline dei cuscinetti, le ho pulite con un panno e ho rimontato. Ora due scorrono lisce, mentre la terza da lo stesso problema, ovvero scorre in alcuni punti e si incastra in altri - non credo ciò sia dovuto al precarico quindi.

Ciao, dopo numerosi tentativi in autonomia ho deciso finalmente di iniziare a confrontarmi con la community. Dopo aver attestato la qualità dell'hardware fornito da duet3D.com ho deciso di assemblare una Rostock delta printer seguendo le linee guida della build di DC42 ( ) - per ora non sto riscontrando alcun particolare problema, se non con le guide lineari da lui consigliate.
