Hi everyone,
I just added a Quick Disconnect assembly between the Printer Module and the A350 module mounting plate. This extends the Printer Module out 10mm in the Y axis. How can I adjust the Y axis coordinate to compensate for this? This needs to be done to correctly recalibrate the machine.

Most people just accept the loss in print area. I know I rarely need the whole 125mm x 125mm of my Original’s bed. 125mm x 115mm would only be noticed during calibration. Given your much larger A350, I wouldn’t worry about it.
But if that extra 10mm is important, you need to find a way to shift the bed forward, or move the Z rails backwards. Drilling new holes in the base is relatively simple, and probably easier than mounting the bed 10mm forward. If you want to be very precise, I’d recommend a drill press for a perfect 90º hole. But realistically, with 4 holes and a flat mounting plate, you shouldn’t need them. Make sure you de-burr the upper surface around the holes, or that might throw the Z axises out of true.
Although moving the Z axises back is slightly tricker on the A250 and A350. It’s important that both Z axises move the exact same amount. You might want to design and print a jig that registers in the existing 4 holes, and provides a punch location for the 4 new holes. That way you know you’re drilling all 8 holes the precise 10mm, and the bit can’t wander during drilling.
Go into your settings, 3D Settings, Quick Swap and make sure that you have the right settings checked. I had to go into the settings and change mine to what I have, then it fixed it self.
If your quick swap solution is not the standard Snapmaker solution, you can modify the work coordinate system of the Snapmaker. More info can be found here: Maximum Y Position 347mm? - #3 by Hauke
In case you use the Snapmaker QSK, @X-Terra ‘s suggestion would be the right way forward.
