If I can't find some linniar rail at the right price I will probably go for a aragement like this but with a deralin caridge that houses the bearing but allso as a guide even though the bearings are almost a perfect fit width wise. I will find it hard to find the cost saving of linniar rail viable over the time it will take to design build and set up my own method

No, no, i have prepared the money for the Hiwins or the chinese MGNs. I was just exploring options as its a low demand machine.

As i said quality is the Top priority, not speed. So i will not use a thicker wire than i use now 0.16mm. I could go even 0.10mm. I am using constantan wire. As when you cut only and mainly letters, later you need to repair the cut on an A for example. So thats time, and time is money. When i cut so much letters that 200mm will take me all day , that will mean i make money enough to make a second machine

I will be interested to hear which rails you go for then, it seams crazy to use genuine hiwin for the amount of use it will get compared to my cnc but it's hard to know what you are geting from Chinese suppliers

Well, 260euro for 6x 1300mm + 6 MGN12H, just payed it so is done.

That will not stop me buying the Delrin balls though. Just for the experiment. By the way as the guy originally designed the bearings not in parametric, i took my time yesterday to redesign them from scratch. I did not like the not squarish design. I have also some other idea about the preload and how will look at all. This is the result for the moment. More purification when i have the balls and have tested the length so the balls fit tightly and exactly
