Tell us about yourself!
Sorry, I never found a fix for this. I eventually swapped it out with one of these; https://www.adafruit.com/product/1602 - which works perfectly fine for my purposes (and was a lot cheaper in the end than assembling 8 of these boards)
Thanks for the info! Using MDF makes sense... most of the structure of my current machine is much harder wood and/or metal. Maybe I need to look for more pliable materials... Back to the drawing board!
Thanks for this instructable. As it happens I am building a CNC machine as well and your design gave me some new ideas on how to proceed.I do have 2 questions for you;1) how do you keep the bearings from slipping on the u-bolts? It does not look like they are firmly attached at all.2) have you had any trouble aligning the pipes so the various parts run smoothly without jitter? I'm asking, because I am currently using solid metal rods of roughly the same size, but making sure they are in absolute alignment is a bit tricky and when they are not, the machine jitters quite a bit.Thanks!
