(I’ve been thinking about this and saw that someone else had posted but replies are closed.)
I would love if someone created a pen holder that attaches to or replaces the current one that has gears to adjust the pen in x/y directions (kind of how the fine adjustment tray on a microscope works).
This would be amazing for registration with pens of differing sizes or colors. Any adept 3d print masters in here?Do it in software!
Write a short script using AXICLI to move your new pen to, say, location 1 cm in X and 1 cm in Y.
Install pen 1. Use a script to make a single dot there.
Install pen 2. Use script to make a single dot
Measure the distance between the 2 dots, in mm
(say you see it as +1.7mm in X, -2.3mm Y)Now add a bias of -1.7mm X and +2.3mm Y to all Pen-2 AXICLI or Axidraw commands.
I built a home-brew pen-changer that switches amongst 4 sharpies. Different sharpies may have different diameters, and my Axidraw pen-holders vary slightly, so when I need tight registration, I’ll make fine-position adjustments using Axicli commands
Cheers, -Cliff.
