Never had that problem before but my last print produced this.
I'm some kind of frustrated now. One step forward and two back.

Update: Found http://www.soliforum.com/topic/1466/sd3 … -shifting/. Going to check

M201 X9000 Y9000 Z100 E10000
M203 X500 Y500 Z5 E45

but the motors sound like way underpowered not even moving. Definitely a board,signal issue. I rechecked voltage. ugh this thing is a lemon somethign always broken, whats next?

I thought I had it fixed after alignment and switch to glass bed. Which was night and day for level pritns, quality 1st layer starts stick etc. made a big differance for calibration very consitent

Well I amde 2 small prints nop problem and went for a big part. half way through 141 of 250 layers. machine stops frozen and shifted to front now not back (a first) whihc tells me maybe it was too much flow now or dragging?

Either way it appears board is fried? I can connect and turn heaters on/off but the RH shows all the m code values as 0? I tried reloading firmware and it loads up fine but all motors will not respond just heaters. I can send manual M92 codes then try to move and they all grind a little but basically seem broken?
WTF was this my problem all along a bad board?

It later came back after the front Y bearing holders cracked then snapped. Maybe check them aswell?

Cheers

I had had flawless printing for months and then all of a sudden I was getting a shift on the Y axis, which then got worse and worse.
During my last print I could see the belt was jumping so I pulled the power to figure out what was going wrong. It was only when I tried to move the carriage forward by had that I found the problem was simply the filament had gone tight due to the spool getting itself in a bind.
Due to my set up it had somehow jumped off of the spool and wrapped itself round the spindle so it would feed for a bit the go tight, then feed and go tight. This would show up as the layers kept going backwards as the layers went up as it could go to the front with the filament like that.
This seems very much like you pictures.

The bit that got me to start with is that I was watching the belts and carriages but never thought to look at the extruder as it was still printing.

Ian made somethng that's on thingiverse, but if you're unable to print you won't be able to use this one.  You could however fashion something up similar with a paperclip and some tape.  At least then you know you have equal tension and take one thing out of the equation.

They said yes. It starts out with great prints then wham around layer 16 it goes to pot.

I did steppers at least 3x and have them dialed in
I removed the rods lubed them over dozen times and got the to flow freely
I have the tension in various forms of looseness.

I did finally get the problem to occur within the first few layers whihcis betterthen layer 18 and waiitng but it is same thing walk back in y
It occurred after I tension one side and not other.

So I think maybe I am too loose I will try one more time
steppers
belt tension
alignment.

I wish there was better specs for proper tension and alignment guide tool or something
