@fcwilt Thank you. Sounds well thought out!

@fcwilt said in Pulley VS belts:

Salut,
Je suppose que vous parlez d'une vidéo? Je peux certainement en inventer une rapide si vous le souhaitez.
J'ai inclus un capteur de butée sur chaque axe Z qui gère le lit s'il est grossièrement hors de niveau.
Ensuite, la fonction de mise à niveau automatique termine le travail.
Frédéric

Indeed I would like to see the result on video, but I don't want to disturb you! Did you create your printer by taking a model or plan from the internet or did you create it according to your own plans and ideas?

@mrehorstdmd impeccable !!

@fcwilt said in Pulley VS belts:

Très heureux avec les resultats.

Hi Frédéric, This is exactly what I want to do ... I want to put three independent belts each with their own motor (in a triangle position on the bed frame) with the automatic leveling ... Do you have a demonstration of your printer? Thank you

@mrehorstdmd said in Pulley VS belts:

Mon imprimante utilise des courroies pour soulever l'axe Z et un réducteur à vis sans fin sur le moteur qui empêche le mouvement du lit lorsque l'alimentation du moteur de l'axe Z est coupée. Ça marche bien.

Do you have an example of your reducer ?

Thank's

@Veti Thank you for that clarification…

Good morning all.

Straps instead of lead screws for guiding the bed (Z) on a CoreXY?

I am thinking about modifying the displacement of my bed on a CoreXY. My idea is to replace the lead screws with a belt system ... The advantage in my opinion is that this system is less strict in alignment and therefore has less friction. However, the flaw is that you may need a pulley system to increase the force and find a solution so that the plate does not come down when the machine is off. Who uses belts on this type of installation?

Thank you

@ziggymanpopo Late response due to my work ... Thank you for sharing, I admit that your technique has already turned in my head!

Good morning all,

I'm using your time to do a little survey ...

What do you use as a slicer?

Personally, I used Simplify3D quite a while, I was almost happy.

Cura, I've always complicated it a lot so I can't assess how it looks.

And there, I have been working with PrusaSlicer for 6 months and find it perfect.

Thank you

Thank you for your explanations !

Hello, try to have three sounding point polls.
I put this command : M558 P1 C"zprobe.in" H5 F120 A03 T10000 S0.03 , but I only get two polls at most each time. Thank's

@Phaedrux said in Purge and prime nozzle:

Le résultat final est une petite languette de filament qui est facile à retirer du lit et laisse la buse très propre avant le début de l'impression.

I have modified some values ​​to adapt them to my configuration, and it works very well ... Thank you

I definitely left the capacitive probe to the detriment of the mini IR probe.

The reason is that for me the weight of the capacitive probe was a bit too heavy. She was exerting a difference on my bed when polling.

FYI, my bed is not absolutely stable and the slightest difference in weight causes a difference in the measurement in the height map.

I will be working on another much more stable bed system soon, so I will test again.

@Phaedrux said in Purge and prime nozzle:

Je l'utilise pour une buse d'amorçage et cela fonctionne assez bien.

Perfect, I'll look into it as soon as I have some time ... Thank you

I'm desperately looking for a way to start all my prints with a light purge and prime my nozzle.

I would like the front right of my bed to a place where the impression is not possible (I know my X&Y) that my nozzle purges a small amount of material then a light rubbing over a small distance to clean .

To be included in the slicer startup G-Code or as a file? Do you have an idea, or are you using something extra? Thank you

@Veti said in Capacitive Sensor:

Y252 ne peut pas être atteint avec un décalage de -43
changez ceci en
M557 X11: 250 Y11: 220 S20; définir la grille de maillage

thank you,

Indeed, with that it works ...

On the other hand, depending on the tests carried out, the capacitive or IR probe is similar. I would tell you that my finding to come.

This configuration works perfectly with the IR probe.

S2 probes the 4 corners (2X2).

If you put S4, it will probe 4 points on the first line multiplied by 4, so 16 points on the bed.

This is valid for S3, S6 ...

@Veti

I have known this for a little while and thanks to this forum that there is a difference between G32 and G29. It was just a tip in case ...

@Veti

Exactly, I thought about taking the offset of my probe ... the G32 work good.

Return to the installation.
The wiring is very simple and the adjustment of the probe in Config.g too.

Where it goes wrong is with the mesh of the bed ... impossible to have a complete mesh. The nozzle only probes the 2 ends of the front of the deck and stops ... yet normally it should probe all 4 corners as configured.

Tired of searching, I will put back my mini IR probe which for me is not exceptional either (I expected to be frank to be more precise).
