thanks for the reply, could you tell me wich version you're using now?

I just about solved the issue by updating slicer.

If your object is too short in one direction (either X or Y), then you need to adjust your Steps/mm values in the Firmware EEPROM. Usually the SD is shipped with the same values for X & Y (88), but I found that my Y dimensions were consistently short, so I needed to increase that value to 90.

In Repetier, go to the Config menu, select Firmware EEPROM Config, then change value of your "Y" setting to something higher (90-91), save to EEPROM, reload the config and try a test print.

NOTE:
You should also check your custom GCode in SLic3r Printer Settings to make sure that they don't override the EEPROM values.

I am having the same problem you are and I cant find the problem. However my size difference is 1 mm.
Currently I am scaling up the prints in the y direction to compensate but it is still very inconvenient

I reinstaller the second Y belt, realigned everything and the problem persist.

I don't know what the problem is

Hi everyone,
My friend lent me his solidoodle 3 he own for few months now and he tell me to check it to see how I could set it and solve some problems. He already did some calibration PID, E step so the 1 wall cube is ok with 0.42mm wall thickness. My extrusion multiplayer is 0.7 to achieve this.

By printing this cube, I'v found the y measurement are off (in minus) by 0.025" =0.6mm. The error is the same for 1 or 2 inch long cube so this is not a step error. I put a 1" range dial indicator on it and the backlash on belt is less than 0.1mm. Also used it while printing a 0.75inch cube and the y displacement is 0.715 (sould be 0.733). The gcode says to move 0.733.

Oh and I forgot to says I disengaged the Y belt on the opposite side of the motor but I'm printing on the moror side (x=10mm) so there is not that much flexion on the print
Even with thoses 2 belts, the error is the same, holes are obvoiusly oval and honeycomb pattern are "not aligned"

I'm using repetier host 0.85b and slic3r 0.9.9

Y motor stay cool
x motor become pretty hot, I'm going to lower the voltage a bit!

no upgrade done yet

any idea?
