Troodon 400 bltouch trouble

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

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

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

@bubblehead concentrate on getting the BLTouch to deploy and retract when you send M401 and M402.

We have one other report that BLTouch doesn't work when connected to duex.pwm4 or duex.pwm5 and using RRF 3.4. I will test this next week when I am back in the office. Meanwhile you could try using port duex.pwm3 instead, or use firmware 3.3 instead of 3.4.

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.

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.

You define the points to probe in bed.g

Is this with firmware 3.4 ?

@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.

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.

I had the same issue when upgrading to firmware 3.0 and the solution is really easy I downloaded the attached 2 files for deploy probe and retract prob from Robert Luciano link below and everything worked perfect.

@bubblehead Hi, i have the exact same hotend and machine, and am now having the same issue. I then upgraded to 3.0 and would like to revert back to factory firmware - where did you get the original firmware? Can you supply a link please. Thank You!
