@TwoTone David, after a good calibration, if nothing changes what do you think would cause the probe to not trigger.
We printed a pretty good layer test after a good calibration. See image.
The next night went to calibrate and on the first point it didn't trigger and pushed the hotend into the bed. Nothing had changed.
Ran a calibration again tonight, worked perfectly twice.
Tried a third time and same thing, first point didn't trigger.
Bed cold.
@dc42 Thanks again for all the support.
Worked perfectly with bed off.
@dc42 This is the bed heater.

@dc42 the commissioning went well. I noticed a large difference in the amount force of the tap needed to trigger it vs the first V3 I received.
@TwoTone David thanks again for the help.
Still having issue with the installed V4.
I can heat the hot end up, fan and LED running and no issue, the probe reading stays at 0.
When I started to heat the bed the probe would start fluctuating between 0-1000 stilling still in the homed position.
I double check all the wiring and the probe wiring wasn't running near any thing else that should cause interference.
Just to be sure, I ran new probe wires outside of the machine, away from any other wires and still have the issue.
Any thoughts?
@dc42 Thanks for the quick response.
@dc42 it's a v3. The vender chose to send another v3 replacement.
The bed is screwed in and then I have an AL heat spreader and glass plate which a just clipped to the bed.
@dc42 I received the new effector and had the same issue at stock sensitivity.
Lowered sensitivity to 30 and the first probe was perfect, kissed the bed and moved to the next point.
2nd point false triggered after only going down around 5 mm.
3rd point touched the bed, with very slight effector tilt.
4th point another false trigger.
5th point basically smashed the bed and I had to turn off the machine.
Seems really inconsistent.
I added the nylon spacers and I did notice a difference in how hard I had to hit it to trigger it.
But when doing the calibration, it still doesn't trigger until well after the entire assemble has starting tilting.
@Phaedrux Thanks for the feedback.
I think I'll try small plastic washers between the mount and pcb first.
I hope that will allow the PCB to flex enough.
@Phaedrux Let me know if you need a different angle. Thanks
Rockstock Max V2 on 3.4.5
I've gone through the set up for the effector and everything checks out based on the instructions.
Seemed like I had to hit it pretty hard to trigger it at the stock setting.
I ran a calibration and the effector end up tilting before triggering.
I lower the sensitivity to 30 and it still ends up tilting the effector before triggering.
It does trigger, but I would think it should trigger before the whole assemble starts to tilt to one side.
Do I keep lowering the sensitivity until it stops?
Other suggestions?
@dc42 Thanks for the clarification
@dc42 Thanks for the reply, what about the soldered jumpers on the effector?
I'm upgrading to a Smart effector v3 and I'm a little confused by the PT100 wiring.
I currently had 2 twisted pairs running from the daughter board to the PT100.
The connection on the bottom for the temp sensor is a 2 wire, so if I run 4 wires to the 8 pin, do I need to remove the solder jumpers and do I need to do anything else.
Is it worth the hassle? I vaguely remember when I first built this printer, reading the twisted pair helped eliminate noise and poor temp readings.
@dc42 I have a pt100 with daughter board.
@Phaedrux thanks for the reply.
My Hotend is showing 2k at room temp.
When I turn on the bed I got an error that it wasn't heating up fast enough.
Under Extruder control I can change the feed amount and rate, but can't click on retract or extrude.
I've updated the Duet 2 WIFI firmware to 3.4.5.
I was hoping to get some help reviewing my new config files. config.g
I have a delta smart effector coming for the Z probe and a PT100 at the hot end, 2 extruders with one hot end.
Please let me know if I missed any info you'd need.
Thanks.
