hey #plottertwitter I am moving and need to liquidate most of my collection of vintage plotters. If anyone is interested, I have a Roland DPX-3300 with stand, an HP 7550A and a Phoenix Contact CMS-P1 for sale. They all are working and are located in BW Germany
@schwittlick_ over the time i found three methods: 1) the fast hack - good but a bit imprecise. 2) 3D printing - gave me problems with the automatic pen change 3) A drilled out original pen (best option) the old fiber markers are all dried out anyway.
