Parf MK II Guide System Problem. I bought the system in 2019, and use it a lot. The system is ingenious and I am very excited about it. But it has amazed me from the beginning that I often had a hole that seemed out of line with the rest. A plate where the holes had the same distance 96 mm had no problems, but when I used 48 and 32 mm hole spacing, there were problems with poor alignment. I thought for a long time that it was me who made the mistakes but after I have investigated the problem for a long time, I now think I have found the problem. It is impossible to see the problem with the eyes and very difficult to measure, but I think the method I use in this video documents that the problem is real. I think and hope these are isolated errors. I have contacted the manufactur about the problem and I received a positive response, they recognized that there was a problem and sent me a new set of rulers. An ingenious system and a responsible manufacturer, it can be recommended.
Thanks.

Test your system so you do not waste time and materials on something that can not be used.
