Hi, I've finally had a chance to assemble my Lead CNC Machine and I feel like I'm stuck on adjusting the Y-plate assembly on the C-Beam. I'm sure I assembled the wheels correctly and the entire Y-Plate. When following the video instructions (OpenBuilds LEAD CNC Build - YouTube), I just can't seem to get the wheels adjusted equally on all four sides. Before I put it onto the rail, I make sure that the eccentric is in the open position and then start with the micro adjustments. Beyond the video, are there any other tips/suggestions that I can look at for getting this adjusted properly? I think I'm just sitting with a newbie problem here (never worked with eccentric spacers before).
