So today i found my MPCNC al crooked and out of square.
Turns out what i had feared during the winter had come true in the summer.
I use an converted glasshouse (kas) as hobby space and the last few weeks have been exceptionally hot.
The PLA has started to become soft in the heat and the XYZ gantry was completely unuseable.
Here are some pictures: https://photos.app.goo.gl/xiy3JPhnCGhzC78y5
Well off to print a new XYZ gantry i guess. in petG this time!
