NanoEls-imperial

Cheap DIY Electronic Lead Screw (ELS) based on Arduino Nano for metal lathes. Supports Metric and Imperial measurements

This is a modified version of NanoELS with added support for inch measurements and tpi pitch. Only h2.ino has been modified. Internal measurements are stored in thousandths of a mm.

Other Changes:

• Changed Display format
• Unlimited list of preset pitches, unlimited list of step sizes

Known Bugs

• Cumulative error when moving position in inch or tpi mode due to rounding (minor effect when step is set to 0.001" or 0.01")
• Not currently possible to directly set non-integer tpi pitches. They can be set using pitch mode. ie. 11.5tpi can only be set as 0.087" pitch

Manual:

• B1 Change Display Mode (Angle/Rpm/Version Info)
• B2 Cycle Move Step size (s/m/l)
• B3 Cycle Preset Pitch
• B4 Cycle Unit Mode (mm/in/tpi)
• B5 Disabled/Debug Info
