Welcome to the SeeMeCNC Community

I designed and built a new printer based on the mag arms... Some specs: - RADDS controller with 0.9deg steppers running 1/32 stepping - RADDS LCD controller - build area 280mmx410mm - seemecnc onyx - seemecnc exstruder - e3d v6 hotend - 9mm gt2 belts - 2040 and 2020 extrusion - aluminum corners - li...

Don't know if there is a pull force value or something.


Either way, thanks for the feedback guys.
I might try one day this mod.

Yes the strength of the magnets I chose was a very important part of my design.

I have been using them for a couple of years now. I have never had the effector come off like that. Could be I have my settings tweaked and don't run into those issues. It's always a possibility for it to come off. I wouldn't recommend anyone print unattended. There is too much risk of a fire.

Do you have fans cooling your print?

Looks good Hax0red...post some pics of you build in my mag arms thread

Looks good. Can you post some details on how you have that fan setup?

My theory on why the others connectors didn't work was because rapid retracts caused the teeth to bend ...

The chrome balls are not magnetized so the answer to your question is no.

Hello all, This is my first post to the forum, just finished assembling my first 3d printer (Max v2). I have already started on making my own set of magnetic arms, thank you xnaron for the stl files for the parts. I have been thinking of another way of attaching the balls to the cap screws other th...

Here is a video on the second driver shield I am testing called the RADDS (Reprap Arduino Due Driver Shield)

Looks like filament starvation, is that PLA? You should probably use ABS for the joints. It was filament starvation. Sitting there, the PLA would ooze from the nozzle, but as soon as I put pressure on it at the EZstruder... it would just jam up. I've almost got my setup ready to go. I didn't have a...

I recommend using PLA. It makes a better joint for this application. Use a mix of water and white elmers glue 10:1 and apply to a heated bed of about 50C with a foam brush in a thin layer. PLA will stick to this and will pop off easily when cooled. I have no problem with PLA sticking. It's ABS that...

The key to making sure the balls stick to the screws is to heat cure them. I stick them close to a desk lamp and let them heat up. They probably get to 70 or 80C. As for the printing issue...I use kiss for slicing. I believe I was at 0.20 layer height and I set the number of loops to something high ...

I bought simplify3d recently after hearing some good things about it from friends. I asked Simplify3d for a demo but they refused. I figured that if it turned out to be crap I would fight hard for a refund. I have been fairly happy with KISS slicer but since it's been abandoned I wanted to a slicer ...

Xnaron super nice print, have a question how is the simplify3d software? it really helps? it wortht to have it? Thanks. Yes I really like Simplifiy3d. I wanted a go-forward slicing path as KISS seems to be abandoned by its developer. KISS was my go to slicer and Simplify3d has quickly replaced it. ...

That looks super fantastic!

(and oddly erotic)

Very funny as usual lol

According to Roland on the repeater github issues list the EXACT_DELTA_MOVES subsegment computation was originally written for the ARM version. Have you heard back from him? Yes I heard back from him. He said Due always has it enabled. He made a switch for avr because he wasn't sure the cpu could h...

DSC01827.JPG Xnaron, I don't know if you know this, I just found out today, but there is a special #define EXACT_DELTA_MOVES that improves the delta calculations. It was originally created for ARM boards but .91.7 Repetier has experimental support for AVR. I've enabled it (just add #define EXACT_DE...

Looks good Joe! Be careful with those magnets. They crack very easily. Don't let them snap together.

How are the measurements for the arms and effector calculated, what are the base points, and/or triangulation points. This is inside the configuration.h file for Repetier firmware. Best to view it in a text editor with fixed fonts. /* =========== Parameter essential for delta calibration ==========...
