I'm going to consider this resolved and create a new thread with my new problem where my gantry and printhead are crashing on the tramming sequence.

Thanks to all that offered help.

@dc42

I've reverted back to the firmware that the printer shipped with and the bltouch is working as it should. That's RRF2.03

Everything seems to be working as it should now, except that the gantry and printhead crash during the tramming sequence. I'm in contact with the manufacturer who's been pretty responsive so far. I've got my fingers crossed I can get it sorted before too much longer.

The bltouch is working as it should now. Not sure what the issue was. I am having a new issue where the gantry is crashing when I run a G32. It seems my configuration is off. I don't know where to look for problems with that.

The setup on the Troodon is very much like a Voron 2.4. The Z axis is controlled by four steppers and it uses the bltouch to tram the gantry.

The specific issue is that the Y and X axes are overshooting and the bltouch is attempting to probe outside the bed.

@dc42

After changing the M574 Z1 S0 to M574 Z1 S2 the probe will deploy and retract via M401 and M402.

That's a relief. I'll see if I can get back to 3.3. Fingers crossed. Thanks for stopping in to offer help.

@lo-fi

Sad to say changing the S0 to S2 didn't fix it.

@lo-fi

Thanks, I'll switch that value and see what happens.

That's correct, there is no z end stop other than the bltouch.

@lo-fi The only changes I've made are switching the stock hotend to a Dragon high flow. Didn't mess with any wiring. The stock board is as Phaedrux mentioned a Duet-ish board. It's been described as a Duet 2 wifi with an extension built in or something like that.

Here's the info you suggested posting;

The bltouch is still not responding.

I'll try uploading the files that Phaedrux shared and see if that fixes it. I'll obviously change the parts that are specific to the 400 troodon.

@phaedrux

I've changed the deploy and retract to the RRF3 syntax and cleaned up the config.g file as you suggested but still not getting any control of the probe via web control or hardware.

Perhaps I'll have to contact the manufacturer for their version of the older firmware if that's possible.

@phaedrux Thanks for that. I've removed the duplicate lines but still no functional bltouch.

I don't know what the syntax should be like for the deployprobe.g and retractprobe.g, here is what I've got currently with RRF3. Is there any difference between RRF 3 and RRF3.4? If they're the same I'll just copy and paste them.

I'm a genuine noob when it comes to working with RRF. Would it make sense to simply upload the Troodon 300 config files you linked to and then adjust the parameters to fit the 400?

Thanks again.
