Stretching issue/ non symmetry

Greetings, so basically my problem is the following. My rostock max V2 no longers print within a reasonable dimension. The offset in a particular dimension is far too great. Printing a circle results as an elliptic shape (noticeable only by measuring), square are slightly a rectangle. See picture fo...

Re: What causes this shifting?

I have this issue and the only time I get it, is moving the printer while it was moving. My rostock max v2 has about 900 hours of running and the arms wear out which results as wobbling issue. So everytime I move the printer during operation, it is certainly guarenteed to shift the layers. Therefore...

Re: Custom Extruder for printing TPE Ninjaflex and other sof

A bit of necro, but is this custom extruder for the people who got older kit extruder? I can't seems to figure out the difference between this and the EZstruder from the stores.
I am willing to buy flexible filaments, but prefer to get all the set up ready before realizing I got screwed.

Re: Temperature on hotend is always below target

I just upgraded for a 40W heating cartridge. It works much better, temperature may be off by 5-6C. Now, I'll need to cover any heating parts that is in contact with air.

Might used clay over kapton, might be overkill though :lol:

Re: Temperature on hotend is always below target

Hey,

I was involved with other works and when I tried to check again this week. The heating resistor seems to broken. Temperature is now barely heating properly. And as gestalt mentionned, the auto tuning really blow. I end up having 10 to 1000x times bigger/smaller values in all kp, ki and kd.

Re: Temperature on hotend is always below target

I'll give a check in the next few days, the only way to get the machine print so far is to increase the temperature target and then lower the temperature back. The machine then understand that it "has" reached the target temperature when the real temperature match the one fixed at.

Re: Temperature on hotend is always below target

It's to believe it's something related to the PID value.

No matter how high Kp or low it is, it should have a peak value. In this case, there was no peak, and the signal starts oscillating already. It's like the signal chosen, is different from the signal injected in the controller.

Hi, I just wanted to give an update. I somehow managed to solve the problem. The carriage has too much friction on the T extruded, and as a result there was 2 carriage that could move freely out of 3. So I adjusted the screw and now the 3 carriages could move freely without much friction. It is now ...
