This is my first post so hello to all other builders.
First some info:
-Metric parts are printed in PLA on a Migbot Prusa I3. 0.2mm layer 80% infill.
-As a conduit I am using 25mm aluminium round tubing.
-X and Y rollers are mounted so that the double side bearings are inside the frame as shown in the instructions.
- No steppers or Gt2 belt mounted.
What I am wondering about is how loose the X and Y roller is on the conduit. The side bearings doesn’t even press against the conduit. Is this a normal situation ?
In the middle section the conduit fits very tight, to begin with I thought that it didn’t fit but by pressing the conduit quite hard into the bearings I managed to fit the conduit.
As a result of the very loose X and Y roller I can turn the whole middle section several centimeters.
