Hi there, i’ve ordered a maslow ring kit and set it up with the default frame. I am using a Bosch POF1200AE Router with the Z-Axis mount printed from thingiverse. Everything is working fine except raising the z-axis for traveling moves to next contour. When the motor raises the z-axis, the router just didn’t catch up and the top motor mount part gets loose. I then need to manually push the whole router up and match the motor mount into the housing screws again. Generally, the z-axis raising is really “stuttering”. Does somebody maybe had the same problem or an idea about how it could be solved? I was already thinking about if it helps when i fix the motor mount into the router with some screws? Would really appreciate any ideas 🙂 ---

Hi thanks for the tip. Where exactly did you put the grease? Is it possible from the outside without opening the machine again? ---

Okay looks cool. Didn’t know that i can move the protective part aside without destroying that. Will try that today and report back if it helped! Thanks! ---

Thank you very much @UNUS_TRESQUATRO that worked very well! I just pulled the protective part down from the top of the shaft until i could see the inner workings and gave it some sprays of WD40. Second thing i did is re-mounting the coupler that it sits firmly on the top of the side of the printed part which is mounted to the router. That gives more stability. I did some test cuts and everything is now working really well, smooth and very accurate 🙂 ---

Wd40 good tool, but it will not last long, it is better to use a thick lubricant ---
