Hi There. Just did a cut again yesterday since a long time ago. It mostly went well but as you can see I had severe problems on the middle part. First two passes went fine and on the next one it just worked itself out of the straight cut because the left chain didn’t have enough tension anymore. I‘ve cut this with a new 1/4 inch upcut bit from makermade. 3mm z per pass in mdf Material, 300 mm/min feedrate and speed setting 3/6 for my Bosch pof 1400 Router. On the bottom right you can see another small problems on the outer line.
What can I do to get better results here?
Is the ring too high? Feeds too fast? Should I put the motors mir down or more to the middle (closer to each other?). I’m not very sure where I should begin troubleshooting this. Would greatly appreciate some advices
