bit depth does not match

[shasta]

keep getting this error with cutting bit, tell it to proceed anyway and all it does is shave a little off the cut path, cant really find any info on fixing this. any help deeply appreciated. carving works fine.

In this case it is all about the Z....

The error is because the Z reading at the bit change did not match the first time you loaded the bit.

This can be caused by a few things....

The Z Encoder might be dirty on the back of the servo motor. The clear disk has lines that block a photo transistor and LED Light in the slit slot. Each line makes a pulse. A easy test is to call up the sensor data after holding the Z head up at the top pin. When you call up the z data it will be Zero or 0000 at that location. As you move the head it will start to count.... 0001, 0002, 0003.... To test move the head up and down a few times looking for steady conunting then back to the top pin... IF all is well, back at the top pin should be 0000 again. If not... A loose belt, Loose Motor Screws, Loose Belt screws to z Truck, Loose CLEAR Disk inside the Encoder and lastly a dirty encoder wheel....

Many have had to add a drop of glue to keep the clear disk from spinning on the servo shaft.

A bad FFC Cable can do it too....

Let us know.... When you say YES to refind, it will use the latest data.

which is the ffc cable?

I think you have to explain exactly what happens. Is this a two bit project? Did you see the cutting bit touch the bit plate each time it tried? Rock chuck? Software version? We need more info to make a guess as to the problem.

sorry, still new at the machine not sure what i need to put. It only has a few hours on it but have had issues with this error before but have gotten it to work after a couple of tries. Very simple project with a carve and a cut, have only basic bits, 1/16th carving and 1/8 cutting. It loads the carving bit fine and carves fine, but when it asks to change to cutting bit and i put it in it tries to find it and gives me the error. Have not watched to make sure it touches the bit plate, will try again and see. its a standard new cx machine running 1.187.
