Preliminary List of Needs

Hardware

• Cables need to be labeled
• Cables need to be consistent gage and type
• Connectors need to be keyed (so they only fit together one way) and standardized
• Cable routing and securing needs to be redone
  • If wire ties are used, they need to be trimmed
• Limit switches need to be securely mounted and wired
• Mounting hardware for table is missing an insertion nut
• Attach spindle to keyed connector
• Control boards need to be tested
• Stepper motors need to be tested
• Determine heat sink and cooling fan needs for control boards
• Determine whether control board interfaces with spindle
• Research alternatives for controllers and connectors
• Research alternatives for table materials & mounting
• Mount all power and control in a box with keyed cable connectors
• Install emergency stop button

Stepper motor specs

Note: Stepper motors are Smart Automation SM42HT47-1684B. Specs are on this page.

Rated voltage = 2.8 V

Rated current = 1.68 A

Rated resistance = 1.65 Ohms

Rated inductance = 2.8 mH

possible e-stop solution

Note: Here's a block diagram for adding an emergency stop that looks like it may be a reasonable solution:

Software

Note: This section will be expanded when hardware issues are fixed.

• Determine whether min/max limits are stored
• Determine optimum software versions and document all settings
