felix Pro 1 Huge shifting during printing

Post by kilooli »

Hello
I'm a fresh owner of a Felix Pro 1 and I'm in big troubles...

Since 3 days now, ALL the prints i do are shifted.
There's one or several shifts in everything i print. It's getting worse and worse.

It seems the printer loose steps.
There are small "TOC" when the carriage is moving.
And the it's shifted !
I guess it's when this noise occur that the things are going wrong.
Whenever it's fast movements or slow movements it is the same issue.
I've checked that nothing prevents the carriage from moving.
It is COMPLETELY FREE .
I can slowly push and pull the carriage along the X and Y axis without any hard point.
Nothing or nobody touches it.
The tension of the belt is OK too.

As for now, my brand new printer is useless... :evil:

Unfortunately, Felix support team seems to be hard to reach, so i try to grab some help, here on the forum.

I have videos that shows the problem, if it can help.

Thanks.

Till now I had it 3 times. Two time a shift in X-axis and today in the Y-axis. Seems the motors are not so strong. Or if there is an obstacle in the print it blocks the nozzle. Little humps are no problem but anything over 1mm seems too much. Not sure what to do...
But your problem is more structural.

I had this effect a few months ago.
Tightening the screw of a pulley fixed my problem.
Check that the screws are tightend and attaching
the flattend part of the stepper-axis.

Just ten minutes ago I witnessed another issue. I submitted a ticket also, but here's the text:

"I had a few times the X or Y axis shifted. Now I observed what happened: the right extruder is pulled out of retracted position by the print. This happens if parts of the print get curled-up a bit by the heat. Depending on the movements, the right extruder is pulled down, and will eventually crash into the part.
I think the solution for this particular print is to use the right extruder, but I would like to know a permanent solution."

Hello Guys.

I sent to the Felix team some videos of several
shifted (shitted) prints when the shift occurs (it does a small 'TOC' noise)
I also noticed that the problem was less frequent when the window, close to the printer, was open (i mean the room temperature was low).
So maybe a driver overheat ? Or overtuned ?

Anyway, Felix team asked me to send it back to them for inspection.
I'm missing the printer but printing was not possible anymore.

They were very friendly, smart and reactive, collecting the printer -via UPS- at my place.

I'll inform you about what will happen.

A far as Felix's support disponibility is concerned, i think they are pretty busy, and a 1-1/2 to 2 days delay is necessary to have an answer.
However, I find it very reasonnable, no troubles here for me.

Cheers.

Hello.
Some fresh news concerning my issue.

I got back my printer from Felix 3D
They told me they tuned (down) the stepper's drivers .

I'm printing a lot to test the printer, and at the moment , as far as i can see, everything seems OK .

Cheers
