@WillAdams Thanks for the info. It says:
“For accurate cuts, it is necessary to calibrate the number of steps in Grbl to match the physical dimensions of the belts as tensioned on your machine. Doing so will require precision measurement tools such as a dial indicator or pair of good quality calipers”
I’m interpreting the instructions as follows:
-Install and tension belt by feel matching it to the same approximate tension as the x axis.
-Mill 3 circles and measure with calipers the distances
-adjust my Nomad’s calibration using the belt stretch calibration procedure in the link
My question really had to do how much tension to apply to the belt after I install it. I’m guessing that as long as it is nicely taught, it will be ok given that I have to recalibrate my machine.
