Hello all,

I have a Mankati fullscale XT. I been printing on it for about 2+ years. 

Recently i have decided to build a drone, so i needed a frame. I went to thingiverse and downloaded Hovership's STL files. 

Basically i printed the (clean upper) file at 15mm/s initial and 100mm/s upper layers with no problem (printed a set of 2 in 1 job)

The second file i tried (base lower) file @15mm/s initial and 100mm/s final (printed 2 in 1 job). Layers shifted about 1.25 to the right and it was just a huge mess. It was not the first time that happened. 

So, i figured the software got all confused, because of too many details i was asking of it. Maybe i made it print too fast. Ok, fine. I reset the job and printed again with 15mm/s initial and 70mm/s final.

Same thing happened. 

This time i uploaded a single item. I did not print 2 copies of the same job. Basically the print failed because the layers shifted settings were the same, 15mm/s initial and 100mm/s final.

The next step would be to check the file itself by importing it into a 3d modeling software. I will also try to slow the print speed way down. I really do not think this will help. I think is something with the file itself.

If anyone has any tips....

Thanks!

After opening the STL and saving as a part file and than saving it back to STL i was hoping that this would eliminate any software glitches. It did not I Printed (base lower) @15mm/s initial and 50 mm/s final and it failed again. The next step would be to try the same file on a Prusa i3 that i built a few months back to see if the issue reoccurs. Another option is to redesign the file from scratch and try to print it that way.

Thanks for your reply.

I am trying to use both.

Whenever I use USB, it usually cuts out at random times, so I dont use it.


I used SD Card for printing

I just updated the firmware and the software and now the print looks like this.. every layer is shifted the same amount in the X-direction. (Before it was just the first few layers, now it is all of them.)   

Y-direction is unaffected.

Hi Leeman

Looks like the issue I've experienced some months ago : the prints were leaning always on the same side using dual extrusion.

I had to upgrade the firmware to Marlin 1.1 RC8. Now the stable version Marlin 1.1 had been released so I'll go for it in your case.

I've made a post in this forum's section for the new firmware upgrade

Hope it helps

David,

Thanks for your reply. This is not occurring on dual print.

It is shifting by the same amount each layer.

 

I have tightened all of the grub screws in the gears but the problem still exists.

I have tried several different software and firmware without success.

I really don't know what else to do, I have been stuck on this issue for 5 days now.

I am at the point where I want to throw this Mankati machine in the bin and buy a different brand and forget the whole bad experience with this company..

Hi Leeman

Seems the issue is a software / firmware problem.

Are you still using Marlin 1.0.x or "official" Mankati Firmwares ? If yes, I do recommend to upgrade to an open source Marlin 1.1 with the appropriate configuration.

I have a post in this section of the forum on how to upgrade.

Which hot end are you using ? Right one ?

Have you tried with another slicer than Cura ? I had issues with Simplify 3D because the offset was done by an older version of Marlin with round off errors.
