I made a new pen mount for the x-carve. Check it out X-carve Pen mount by tseaman87 - Thingiverse.
Is that an open builds linear actuator holding the router? How do you like it over the stock one from Inventables?
That is a C beam from open builds but I only bought the rail and the carriage. The other parts to make it work are just modified x-carve z axis parts.
Is there a spring incorporated to ensure pressure on the paper?
When I have the marker cable tied to the Dewalt mount, it doesn’t always retain pressure.
I had a light spring on it. And it worked. But I found the weight to be enough on mine so I took the spring off.
