I recently made the jump to Mainline to facilitate installation of an Eddy Duo. Things went relatively well, but I need some input on an issue causing a bad first layer. When the machine runs QGL, my Z1 is reporting a deviation of roughly 3mm. The software does attempt to compensate, but I’m having …

I may have been a bit quick to post. The aftermarket bed plate is small enough that the Eddy probe is actually scanning the edge of the bed. I put the sovol plate back on and got better results from the QGL and mesh. [Screenshot_20250727-105652] Small plate centered on the magnetic bed. [Scree…

I managed to kick off a print by shifting the part footprint to the rear of the bed. I suppose a teardown is in order to find out how to correct the bed level condition. I see in the other thread that the idea of a glass plate was mentioned. [Screenshot_20250728-090426]

I will check that. As a temporary solution, I’m going to try to get the magnetic layer flat as described on the R3men graphite bed webpage. I think that will be a work around unit I’m ready to throw more dollars at this machine.

I read that. I will be migrating to a graphite bed eventually and may devise a tripodal mount of some sort. In the interim, I found the issue at hand. I actually had time to get down at eye level and watch the first layer print. I found that the rear Z belts had plastic debris down inside the pulle…

I wanted to mention this before, why not rigid mount one point of the bed and install Oldham couplings for all other positions?

Ideally the bed should have 3 distinct mount points. single degree of freedom (yaw) 2 degrees of freedom (linear through point 1 and yaw 3 degrees of freedom (X,Y, and yaw) However with the small magnitude of the frame flex I feel that the standoffs (if not overtightened) will be flexible enough …

[Screenshot_20250729-204633] After reading the other thread, I immediately conceived of ball bearings in concave pads. I ran the idea by a friend and he replied with Oldham joints. These seem like they would be relatively easy to retrofit using the existing mounting locations.

You’d have to lock 1 slide on 1 of the joints or bed could rotate around your main mount point
