Ok, that’s what I suspected. If that’s the case, the instruction documentation needs to be updated to reflect that the wasteboard is not supposed to be flush with the ends of the wasteboard supporting extrusions.
@NathanButler the instructions are open source and hosted on github. This means you can do a pull request if you wish. @JohnHayes is the administrator of the instructions and can take a look at the step you are concerned about with you to see if it needs to be updated.
@NathanButler I noticed you have the machine on shag carpet. We suggest putting it on a more rigid stable surface like a table when you start running it. The shag carpet might also ruin the electronics if you have static electricity.
Thanks for the advice, Zach Thankfully I haven’t turned it on yet and have merely been assembling on the carpet. I actually went and built a torsion box out of 0.5" MDF with 2" tall core pieces. I’m going to do @IanWatkins mod to stabilize the machine and flatten the work area by bolting the wasteboard, on top of two more pieces of 0.5" MDF, straight through the torsion box with a few 0.5" diameter 5.5" long bolts. I’m hoping that kind of stability will enable me to reduce runout to the point that PCB milling will be achievable without much tweaking after it’s dialed in.
