So, I didn’t realize this was happening because until today I wasn’t running across the whole length of the axis as I was doing small tests.
I ran a program to put some pockets into my waste board and I split the programs between drilling holes for recesses and for the actual hold down inserts. In the second photo with all the scribblings between holes, the middle row is the distance between top and bottom… which is pretty steady with some minor variance, but the top and bottom rows have what I would consider significant variance - mostly because the circles aren’t “perfect”, they are skinnier across X versus Y.
I went back to the pen and the crown and noticed that the circles on that weren’t perfect either. Same issue with the circle below the cross being skinnier across the x axis versus the y.
I’ve included a bunch of photos. If there is something specific I can snap a photo of, please let me know.
Overall, it just looks to me like the x axis isn’t traveling “at full capacity”.
Not sure of what/how I can fix this issue… I kind of think it might be that the x axis motors aren’t getting enough juice (??), if that is the case, I’m not sure how to adjust that since the steppers on the board do not have a trim pot on a typical set of A4988 type drivers, that I can find. If not this, then any other thoughts as to what might be causing this?
Thanks.
