Welp... as always, you guys are right. Must have had a short in the original wire because I got the new BLT and just by replacing the harness did it start to work. Let this be another lesson to everyone... if your BLtouch doesn't work, get some new wires.

That did it! Thanks @jay_s_uk !!

remove these lines from your start gcode

I will try that and see if it works.

Alright, so I feel like I have come a long way since I replaced my CR-10S board with a Duet. I love it, but I cannot for the life of me figure out how to get it to print faster. I have a Hemera and it was printing lovely at 160mm/s, but now I can't get it over 24mm/s.

I've read other threads and adjusted my acceleration and jerk control but I get no changes. When I am homing it moves fast, but when I start printing it slows down. I'm sure this is something I'm doing in Cura, but again, I've tried everything I could think of and need another pair of eyes to assist.

Slicer: Cura - Deleted printer and added using RepRap flavor
Homing is fast if I do it through the web. When it homes with gcode through the print it is slow. This is where I think the problem is but I'm just missing it.

Welp... as always, you guys are right. Must have had a short in the original wire because I got the new BLT and just by replacing the harness did it start to work. Let this be another lesson to everyone... if your BLtouch doesn't work, get some new wires.

@Phaedrux said in BLTouch not Triggering:

The way the BLtouch triggers and then immediately resets means you won't usually catch a glimpse of the z-probe status changing in the web interface, so that's not a reliable indicator of it working. The static test during a G30 move is the only way to really know.

I don't think it will make a differene but you can try removing the ^ from the pin name C"^zprobe.in"

Having a second bltouch to test with might be a good sanity check.

Just purchased one from Amazon. Fingers crossed that does the trick. I'm doubtful though because this was working just fine with my other board, but I get it, it's usually the easy things that wind up being the issue.

So... also, the Z-Probe always reads as "0" no matter what. Same on either of the pins I try. Is there a way I can test the signal with a multimeter? To see if the BLT is sending a signal to the board? Then, if it is, I couldn't imagine the board being bad, but then again stranger things have happened to me.

@Phaedrux said in BLTouch not Triggering:

Ah ok. I guess that would have been added after you shared the config.g above.

I removed that line and re-ran M122... heater7 issue isn't there anymore. Still no luck on the trigger though. Tried the logic that antclabs suggests but same results.

@Veti said in BLTouch not Triggering:

if deploy and retract are working then the servo part of the bltouch is working.
the trigger signal is the problem.

Yes, just wondering why it's complaining about heater 7. I don't think it's references in config.g other than in his M950 for the bltouch.

Is it because I added the line:

M307 H7 A-1 C-1 D-1

@Veti said in BLTouch not Triggering:

M280 P0 S150

Where would I put those commands? I ran them and they don't do anything. Well, it comes up green, but that's it.

@brewchester said in BLTouch not Triggering:

Error: Heater 7 not found

Is the deploy and retract commands working? M401 and M402?

Yes they are.

Error: Heater 7 not found This error message is a bit confusing then.

Could you change from that heater 7 pin to heater 3/pin 8 on the expansion header? Then change the reference to exp.heater7 to exp.heater3 and send M98 P"config.g" again to see if it's still complaining about heater 7.

I've done this a few times and it has the same affect. I've tried 3, 5, and 7 and it still won't trigger.
