Alignment

Y1 belt kept rubbing on idler side. Idler was slightly slanted, and wobbly pulley on x motor did not help.
Enlarging hole in pulley from 6 to 8 mm is difficult with mag drill. Did it in 0.4 mm drill increments - drilling is not self-alogning even with this small increment
Z pulley wobbly and bend from too string vice hold
Z and y1 pulleys replaced - these were wobbly
Drilling was done in 1/64" (0.4 mm) increments starting with 1/4". Motor shafts are 8 mm, pulleys were 6 mm

At half inch cutting speeds of 20 ipm or 500 mm/min - this is prior to pulley size calibration of about 30% larger pulley
11/12/21 gets us 25 lb towards negative y1, 20+ for both directions of y2, and 20+ lb for both directions of x
Positive y1
