I'm using Cura 4.12.1 and my custom profiles are not linked at all between the printers. Are you using the default profiles? Try making a custom profile for each printer and they should not synchronize.

@gr5 thanks for your help

I just re-tightened the print head down and noticed better results. The new cube measures as follows: X (20.15) Y (20.23) Z (20.1). I'm gonna re-check the pulleys to see if I can get a closer result for both X and Y. For those wondering about what I did...there are four 2mm internal hex bolts located above the print head. I just tightened those four bolts down as tight as I reasonably can (without stripping it) to reduce print head play on the Y axle.

I was printing at 40mm/sec and slowed down to 10 to see if it was an issue with loose belts. But got the same results. I measured across the face only and avoided the corner bulges. I also measured the upper layer only to avoid the bottom elephants foot. Do you think I should loosen and realign all the axles to be safe? I suspect the problem is on the Y-axis because I noticed some layer shifts in some previous prints (Y direction only). Which is why I tightened the belts and noticed some slight play in the left Y axle. Actually I just pushed on the printhead like you suggested. There is no play in the X axis. However, on the Y axis there is a fair bit of movement. The print head tilts up and down when I push it slightly. It looks to me like there is too much room between the center Y axle (where the print head is mounted) and the print head thru hole.

Looks like underextrusion. Since you're using a new nozzle, did you remember to change the nozzle size in your slicer? Also, try printing at a slower speed to see if it improves.

Printer: Ultimaker S5 Filament: Ultimaker Tough PLA Slicer: Cura 4.12.1 Hi everyone, I've recently started experiencing issues with my parts dimensions. I printed a 20mm calibration cube using UM Tough PLA and my results are as follows: X (20.15mm) Y (20.5mm) Z (20.1mm). What could be causing such a large deviation in the Y axis? I printed the cube at 0.2 layer height and 10mm/s print speed, 215 degrees C. I replaced the glass bed with a brand new one and manually leveled. I've re-tightened both the short belts. There was some play in my left Y-axle so I've loosened the pulley and re-tightened the axle. The result is still the same - I'm getting about +0.4mm on the Y axis of my prints. Any idea what I should be checking for next?
