Buildbotics Forum

I put up a new blog article on probing. It provides details on z-axis probing and 3D probing.

I also created a youtube video on 3D probing.

Check them out. Likes and shares are very helpful.

I have not heard of this particular symptom before, but I can say that 'stall-detect' homing is very finicky. I recommend using limit switches instead.

Try reversing the RS-485 pair.

I recommend upgrading your controller to V1.0.3. If you need help with this, feel free to call me at (925)577-9940.

Can you send the gcode program that you are running when the error occurs? Also, what version of software is your controller running?

Does the g-code program attempt to make moves beyond the soft limit settings on the SETTINGS->Motor page for the Y axis? Keep in mind that the soft limits set on the SETTINGS->Motor pages are the absolute limits. When trying to decide whether the program will run beyond the soft limit setting, you n...

Did you move the J2 jumper on the side of the laser driver to the input control position? Also, verify that the full power setting on the PWM spindle matches the full power output to your laser. For instance, if you issue a command like M3 S250 to get the maximum power from your laser, then the PWM ...

If all the specs are the same it should work. However, this is really a question for your VFD vendor to comfirm that the spindle is compatible with the VFD.

Things have changed since these original posts back in 2019 and 2020. Starting with version 15 of our main boards, we implemented the following changes that are pertinent to this conversation: The Buildbotics Controller began to accept 24-48 Volts. The step and direction signal levels increased from...

That would be a question for OneFinity.
