CNC Torch Table v21.08 Data Collection

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 bent 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
• X autoparallel is implemented with oversized x mount holes on x1
• Y autoparallel is implemented with autoparallel y 3D prints and nylon bushings; nylon bushings are longer than needed
• Y and Z only use hollow shaft. Hollow shaft uses nylon bushings, solid shaft uses bronze oiled bushings

Motion Force

• 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 - data?

Speeds Achievable

• 11/12/21 gets us to 3000 mm/min. Above starts to skip.

• Actual initial speed prior to calibration. - 1m/2min = or 0.5 m/min or 20 IPM
• 889 Y limit
• actual motion 26.5 in = 673 mm
