I'm not sure I could make an image/picture that was not materially distorted but I will look into ways to do it.

I would like to run an option past you:

-- Tape the plans to the bed of the rig.

-- Replace the cutter/lens with a stylus.

-- I just saw a "CAM USB camera" online that gives you a view of the exact place where the (stylus) hovers over the plans. (I can not find it online right now...)

-- Then:

    -- Jog the steppers with a joystick to place the stylus over the "start" of the tracing

    -- Touch a button on the joystick to register the current location on the plans/bed

    -- Jog the steppers again to get to another point on the plans and press the button

Observations:

  -- Straight lines would be easy; curves would require help digitizing gracefully, but I have some thoughts

  -- The file of points would have to processed into a file of "cuts".

  -- Plans involving multiple parts would have to be digitized a part at a time. The parts would then need to be laid out on (a 4 x 8 sheet of stock say).

Thoughts?

Thanks,
Tom

Missing link in homing LC10E

Just looking at homing.c source and it has a reminder in a comment.
                   // docs: 'If HOME_SEQUENCE is not specified then this joint
                   //        will not be homed by the HOME ALL sequence'
Do you have a home_sequence set for all joints?

Much respect for the traditional way but I would like to come up with a 21'st century option. Digitizing from the image sounds good. I'll look into it.

Thanks,
Tom

I can confirm that it misbehaves if I change my location to SK.

I will look into it further.
