What is the best way to zero/calibrate the X/Y/Z axes?

What is the best way to zero/calibrate the X/Y/Z axes?

Before I start using the CNC, I wanted to see if anyone had a recommended method to zero the axes. This way the tool paths can start at a specified/precise location, etc.

Also does the boxyz have position awareness? (aka: are the stepper motors aware of the current location of the xyz axes)? I am asking to see if it can detect slippage or if feeds/speeds are to fast for a given material, etc.

Is this a good question?

The BoXZY doesn't have any position awareness. You can tell from closer looking at some technical details. The stepper motors don't have encoders and I would state that the Arduino controller and the used Repetier software is not capable of counting steps. There would be more wires needed to connect the encoders with the controller and these wires should be shielded. Another means would be to use prefabricated active stepper axes, which would increase the price.

My printer proofed this fact yesterday when it printed half of the part with about +4mm offset in y-direction, after an unusual and strange noise.

For zeroing I find the home button(s) absolutely sufficient.

I do zero the z-axis first and insert the printing head afterwards with the thin cardboard between nozzle and printing bed. Then the printing head is not resting at the clamp but about 15mm higher. Only so one may use the full 165mm printing height.

I'd start from the home position for the x and y axis, and then bring the z axis up until it just meets the tip of your bit. If you have a dial gauge that could also be useful if you're looking for extra precision. Starting from home should give you the best repeatable start point, and from there you can macro to your desired location if you're looking to do repeated jobs. No clue on the position awareness, but I'd lean towards no, because if you press emergency stop the X, Y, and Z boxes on the manual control page all zero out without returning the carriage to the home position.

Thank you. Do you consider the x/y "home" to be upper/left when standing above the boxyz and looking down at it?


I see that the boxzy interface manual control "home" buttons do in fact put the position to the top, left as I stated above. The z home button lifts the platform to the upper limit. Thank you
