I Already figured it out from another post on this forum, thx again for all the help guys.. the community is amazing!

Ok Thanks for all the advice so far. I'm almost there i think.. So i've changed what whosrdaddy commented.
Probe works and I've changed the acceleration according to my marlin file thx to Tony. It looks better now.

Just one thing anyone who's using cura and using a precision piezo what is ur start/end script in cura?

Because right now when im starting a print it probes but then starts printing around 3 mm's above the printbed while the probing went fine.

Thanks in advance!

Right guys… I guess i was a little too hasty with making this post making it kind off a mess..

Hmm i didn't realize that the settings had to be changed in the home files too.. seems logical at hindsight. Ill change them now and see if that helps. And for the bed adhesion i know that it's not related to the controller probably just the issue of my probe not working as it should.

The main problem that i have right now is that with that config i posted above i was able to print ( somehow ) but for example when i print the famous treefrog from thingiverse it really messes up the infill since it's moving so "slow" i guess i have problems explaining this but the way it's setup now the carriages pick up speed while they move and they decelerate earlier to comparison to the ramps which is just high speed up to the point it stops. Atleast i think thats the issue but as u probably noticed i am very new to this stuff.

Argh i forgot to list my steppers.

Well all of my axis steppers are NEMA 17 1.8 degrees rated on 2.5 A
My Extruder is a half size NEMA 17 0.9 degrees rated on 1.2 A

And im using 8x2 leadscrews and G2T belts.

Hello good folk,

Recently I converted my home made cartesian setup from a ramps controller to a duet. However I also added a titan direct extruder instead of a bulldog and swapped out my Inductive probe for an Precision Piezo. Now i've been trying for weeks to get it running but for some reason i cant find the optimal settings. At the moment every axis works fine, homing works, probing and making a height map works excellent 80% of the times. But whenever I'm trying to start a print (sliced with cura) it messes up. For PLA nothing is working it wont stick to the bed while i never had problem with that when printing with ramps. ABS seems to work better, sticks well but the prints are deformed which is very strange because when i check the distanced travelled manually with a ruler it all checks out.

I'm not seeing the missing link right now because it all seems so similiar to ramps and that was easy peasy to set-up. And now I cant get a decent print out of this printer.. while im really impressed with the overal ease of use of the duet. I'll post a picture of my build to give u a general idea, please keep in mind that it is still work in progress and i've not done the wire management yet. Also ill provide the config.h and home xyz files below. I would really appreciate it if someone spots where it goes wrong.

In advance i'd like to thank you people for your time and dedication.

Greetings Geert
