Welcome to the SeeMeCNC Community

Ive been trying to print out some thing, for example I was trying to print an e3d v6 mount but the upper plate was too big and wouldnt fit. Some one said I had a XY scaling issue but I dont know what that is and was wondering if anyone could help me fix this.

Hi, maybe it's not a XY issue. Print a 10x10x10 cube, with one perimeter, 0% infill and no top layer. Measure it.

Oh, and did you fix your tower problem? If so, please update your thread so others can learn.

Ok I printed it. its dimension are 11.6 (H) x 11.6 (l) x 11.2 (W)

Do you have the ball-cup arms or the previous version?
If you have the ball cups and your arm length is set to 269 your prints will be bigger. Because your printer thinks it has to move further than it actually does. The ball-cup arms are 290mm long.

But... I don't think that changing the arm length will change the height of a print, and you are printing taller also.

After it to 290 the 10x 10 x 10 cube measures 10.4 (L)x 11.7 (H) x 10.8 (W)

if your steps per mm are wrong in EEPROM everything will be the wrong size... 92.4 is what mine is set for I believe,

Mine is set to 93 is that enough to make a huge error

If you have a v2 and that's the basic steps per mm instead of the extruder steps per mm, yes that is enough to make a huge error. It should be 80.

that just said 92.4

I think he meant steps per mm and not extr. Steps per mm.
By default steps per mm is 80 and extr. 90 something. So unless you've changed it on purpose, it should be OK.

Share your eeprom. I'm no expert but others might see if something is wrong.

The diagonal rod length for the new ball-cup arms is 290.8.

When I get home I should change the Steps per mm to 80. Correct? Because I recently changed to repetier host so I wouldn't be surprised if I forgot to change some settings and right now the steps per mm are 92.4.

well I gave you the extruder steps per mm not steps per mm.... sorry. thanks guys for stepping in here.

hah no problem man

The drive steps per mm is 80. NEVER change this. The extruder steps per mm *default* is 92.4 (or so). That CAN be changed and should be as part of the extruder calibration process.

Thank you for the clarification I was a little confused. Ill be home in 3 hours or so and I will give it a try.

It was the steps per mm. After setting it to 80 the prints were good

Wait now that I changed it Im getting this weird level shifting

If not already, change your rod length back to 269 and do the Z calibration process again.

its already at 269
