Help! cutting air

Using/verifying the BitZero

Here is how I check out the functionality of the machine/BitZero: first check that you have sent the correct Z-axis configuration This can be easily done by jogging down to the wasteboard surface, setting zero, then using the Rapid Position command to lift 6mm above the current zero — measure how much the machine moved — if it’s wrong: go to the MDI and send $$ and check that the Z-axis steps/mm match your machine setup: Belt-drive: 40 Z-Plus: 200 HDZ: 320 ​ ​c.f., Then, clamp a sui…

The other consideration is where the origin is set in the file — if you have it at the bottom of the stock in the file, but set it relative to the top using BitZero, then you will get an air cut as you describe.

To see how to set the origin relative to the bottom using a BitZero see:

Making a parametric fitted box (for pencils)

We secure the stock: [20240128_175637] jog to the center and set XY zero there: [20240128_180026] Position the BitZero on the doubled-up tape and Probe for Z-axis zero: [20240128_180242] then jog to the stock thickness height and re-set zero there. Then we begin cutting: [20240128_183340]
