The extruder.
The stock extruder remained, but gave problems, such as slipping not pulling back properly, so BZ 3D Dual Drive Bowden B-M-G Extruder High Performance purchased. Here I sawed out a bite to put in exactly the same place where the old one was, I removed the switch from the PCB. Then I made a printed holder that is placed on the extruder in which I put a roller switch and connected it to the PCB. Print glued to the holder. The extruder now actually works the other way around, but works perfectly.
Because there is a considerable delay in the extruder, the E STEPS_P_MM should be set to 812.0, this was normally at 154.3. To guide the filament nicely, I designed and printed a new guide.
Esun filament.
Esun filament supplies filament with a hole in the roll that falls over the rotating holder of the Delta so that the filament just lies on the Alu. Created a new holder with a larger edge so that Esun filament also lies nicely on the holder.
Magnetic balls worn out.
With me, after six months of use, 10 of the 12 bullets have worn down to bronze! Have now purchased a magnet specialist of super magnets 12 new and proceeded to lubricate the balls with motor chain grease. The bullets are much stronger when it comes to magnetism than Velleman’s, hope they last longer with that new lubricant too. I can now grab the print head and move the whole thing in all directions without 1 rod coming loose!!!
So this was an upgrade, if interested I put all STL files on Thingiverse. About TomEm - Thingiverse

Hi Vertex Delta lovers,
for those who have also started using the Bowden Extruder in the above way, or those who will still do so. However, when printing TPU something went wrong, the filament got stuck and twisted around everything. To prevent this I made the following modifications. I have removed the hose connection from the Extruder, takes some effort, then drilled the hole a little deeper so that another hose connection can be screwed in properly (do this very carefully, the drill will bite!!), for that also the hole to the drilled guide wheels to 4 mm, do this as precisely as possible. Now the hose can be pushed against the wheels, I also chamfered the hose from above and below. I did that pushing the hose with a piece of filament in it.
Again I hope to have helped a number of people for now or in the future.
Ga na of de magneet bolletjes nog een mooi egaal blinkend oppervlak heeft.
Als er matte plekken op zijn (blinkend oppervlak beschadigd) dan is op deze plaats het bolletje niet meer magnetisch. En komen zo de staven los. Indien zo best de magneten vervangen.
For english members:
Q) Rods come loose from magnet balls (Conversion kit to fixed joints)
A) Check whether the magnet balls still have a nice smooth shiny surface. If there are matte spots on it (glossy surface damaged) then the ball is no longer magnetic at this location. And so the rods come loose. If so, replace the magnets.
Dankje voor jullie snelle antwoord. Had toevallig net neodynium magneetkogels gevonden. De moeite waard om te proberen. Want als die het doet dan gaat die prachtig.
Fijne dag,Willem
Hallo Willem,
Na al de dingen die ik veranderd heb kan ik eigenlijk alles probleemloos printen.
Dus:
Nieuwe echte neodymium magneten, die andere kunnen totaal niet de Jerk aan!
Aangepaste “bowden dual gear extuder”. Met alle modificties, zie mijn andere berichten Ik kan nu alles printen zonder slip!
Spanners voor de tandriemen.
Veren onder het bed, (jou idee) Na goede afstelling hoef ik alleen nog bij Nozzle wissel te kalibreren.
Materiaal wiel bovenop vervangen onderrand te klein voor sommige filament haspels.
Mijn geprinte geleiders i.p.v. diegene met de messing bussen. Bewegen makkelijker, minder gewicht!
Marlin Software geupdate.
Gebruik nu Ultimaker Cura 5.2.1 om te slicen, dat werkt perfect, zoveel in te stellen met dat programma, maar alle instellingen goed uitgelegd.
Zit een Extensie bij voor uitgebreide uitleg, zo goed dat ik de uitleg naar het Nederlands aan het vertalen ben en binnenkort beschikbaar stel via gidhub via de maker van de Extensie.
Zijn over de 600 tekst bestanden met tekeningen.
Snap door het vertalen veel meer van 3d printen!
Ik ben wel al aan mijn 4e BuildTak folie bezig, soms wat te wild met mijn steekmes.
Maak als ik nieuw filament ga gebruiken eerst een temperatuur toren, zit ook een Extensie in Cura die je direct kan gebruiken om zo’n toren te printen.
Maar na al het bovenstaande werkt hij nu als een zonnetje.
Ik weet niet of de shop van Velleman weer op orde is, en of ze nu ook betere magneten verkopen, ik betaalde voor die goede magneten evenveel als dat ze stonden bij Velleman.
Hoor van je,
Vriendelijke groeten,
Tom
Voor mijn Engelstalige vrienden:
Hello William,
After all the things I’ve changed, I can actually print everything without any problems.
So:
New real neodymium magnets, the others can’t handle the Jerk at all!
Custom bowden dual gear extuder. With all modifications, see my other posts I can now print anything without slip!
Tensioners for the timing belts.
Springs under the bed, (your idea) After proper adjustment, I only have to calibrate at Nozzle change.
Material wheel on top replaced bottom edge too small for some filament reels.
My printed conductors instead of the ones with the brass bushings. Move easier, less weight!
Marlin Software updated.
Now use Ultimaker Cura 5.2.1 to slice, that works perfectly, so much to set with that program, but all settings well explained.
Includes an extension for detailed explanation, so good that I am translating the explanation into Dutch and will soon make it available via gidhub via the maker of the extension.
Are over 600 text files with drawings.
Get a lot more of 3d printing by translating!
I am already working on my 4th BuildTak foil, sometimes a bit too wild with my knife.
If I’m going to use new filament, make a temperature tower first, there is also an extension in Cura that you can use immediately to print such a tower.
But after all the above, it now works like a charm.
I don’t know if Velleman’s shop is back in order, or if they also sell better magnets, I paid the same amount for those good magnets as they were at Velleman.
Hear from you,
Regards,
Tom
