First test cut. Z axis not plunging

Hey all! I’m stuck during calibration. Zeroed our z axis against surface for text cut. Next step, I hit make test cuts. Bit raises about 1/4”. Travels to top left for first cut, but lowers to surface but doesn’t plunge into plywood. Ridged with bungee. What am I missing?

Thx all!

I would check all the normal stuff i.e. set screws and such. You may need to loosen up the clamp on the base and/or increase the bungee pressure. The castings on the base and the alignment grove are not the best. I ended up sanding the entire base to remove the imperfections and polishing to 600 grit, I also use graphite dry lube on the router body. There are some simple fixes for the z axis to make it work better if you are interested in that.


I have the bungee cord and the body loosened up. The bit lowers back to where I zeroed the z axis but doesn’t go any deeper. Is there somewhere that I set cut depth for the calibration?

Is this the included benchmark, or is this a CAM file you generated?

When at this zero location, is the traveler near the middle of the lead screw, or is it at the end? In other words, has the mechanism bottomed out?

Pretty much in the middle. During calibration, am I supposed to get a prompt for depth of test cuts?

Not certain that I follow, but in general if the setting ‘z-axis installed’ is off, one gets prompts, if it is on, one should not.

So we are thinking now the Z axis may not be enabled?

Can you manually lower the z below the surface of the wood when not doing the calibration process?

I was able to get it to work. Not sure what I did different though.
