The things I have tried have been the official method as was posted by seemecnc to fix this, as in updating the firmware to use the changed Carriage Horizontal Offset from 35 to 37.5, which after downloading the most recent firmware for the max v2 the amount isn't 37.5 but 38+ which someone mentioned and I never saw any response to which is the version that I'm supposed to be using. I assumed the most recent firmware is the one that I'm supposed to be using.
anywho here are some pics of my issue in particular. As you can see I have a very odd shape when printing, The very center seems fine, the location where Z and Y are printing seem ok, the letter X is half squished into almost nothing (a high spot), as is almost the entire arc directly across from X between the Z and Y towers. The middle of the arc between the X and Y and X and Z are low spots and the filament doesn't even adhear, depsite the glue and blue tape (I'm using ABS) And lastly the inner circle seems ok except for where it meets at the X conjunction where is squish (high point) on either edge. Also something to note about my printer, I didn't build it. I purchased it from the seemecnc fellas at the makerfaire back in May of last year, they didn't want to haul it back and I purchased printing and running fine as it was at the show. Only recently have I really been printing larger objects (past the inner circle) and then decided to try and print out to the edges and found this entire thread and the exact issue i'm also facing. Its a rostockmaxv2 (black).
thanks in advance - david.
Given the distortion pattern, the problem is obviously in the X tower, positioning "short" only when past the triangle. I would check arms, belts, joints, and skates for any play, especially in pulling and pushing on the platform. Tower tilt (out from center) may also be a factor, though I would expect a gradual deviation across the whole surface and not just past the triangle.
Crossing the triangle is where the force on the rod changes from tension to compression, so will abruptly change the platform position for the particular slop amount.
