Buildbotics Forum

Hi Alex,

I'll be on vacation for the next couple of weeks. I will be checking email and this forum and will respond as best I can, but I might be a bit slow and limited in what I can do until I get back.

Please report back on your experience with the WiFi dongle.

OK, just so I understand everything, let me talk it through. You set the absolute position of the Z axis to 0.0045" using the 'Set position' button. The first line of code moves Z up to 6.985" The G38.2 command probes downward by as much as 6.985". It stops when it touches the probe. Finally, after ...

Thanks Alex, Since the built-in WiFi antenna is inside the aluminum enclosure, you must have a pretty good WiFi signal to avoid network problems. You can improve the network signal with a WiFi dongle. If you decide to get one, it must be 'linux' compatible. I use one like this: https://www.amazon.co...

Thank you for your good work on this subject. I am trying to reproduce the problem that you described where "the #<_z> parameter always returns a positive value". I created this small macro: G21 G90 G0 Z10 (debug, Z = #<_z>) G0 Z-10 (debug, Z = #<_z>) M2 This produces two messages. The first says "Z...

I haven't tried it. If you do, please report back.

I learned today that if you click 'Pause' during a probing operation, the machine will estop. I have submitted a github issue on this problem. See https://github.com/buildbotics/bbctrl-f ... issues/301 .

Is it possible that this is what is causing your issue?

We have your pull request and will review it.....thanks

First, I must mention that the OneFinity controller is not made by Buildbotics. They copied our Open-Source design and proceeded to modify it their liking. Beyond that we have no affiliation with OneFinity or their controller.

I think the problem is that the G98 code in your example is not supported.

I have partially simulated this, but what I found is that the controller estops if you click 'Pause' rather than 'Stop' during a probing operation (e.g. G38.2 -Z54). I have opened up github issue #301 on this problem. See https://github.com/buildbotics/bbctrl-firmware/issues/301 Note, I also found t...

Yes, an estop will show up in the logs, but the logs are quite cryptic.

If the machine estops for any reason, all homing information will be lost. This can also happen if a limit switch trips for some reason.
