@dc42 I had double and triple checked the wiring and thought everything to be ok even moved the head around manually and tapped the bed with no issues. I went ahead and secured the wiring harness a little better and wouldn't you know it, was able to complete auto calibration multiple times.

Wiggled the wiring while tapping the bottom and can see that it does in fact seem to be a crimp issue. Just happened to be in the right spot every time I checked it that and the fact that it failed on the exact spot led me to believe it might be something else. Going to re-crimp everything and see what happens. Will update when that is complete.

Thanks!!

@Veti I had not done that as I am able to reproduce the issue manually. If I manually moved the head by hand, wiggle the connector I can cause the failure.

By providing more strain relief for the connector it works without any issues.

So I pulled harness for the sensor completely out. Stuck pins in the connectors to hook up an ohm meter. Jiggled, pulled, push etc on the cable ends and found there are no issues with the cable.

Plugged it back in same issue as before. I tied up the cable to the bowden tube to ensure nothing is getting pulled and everything seems to be working again. Do not see anything wrong with the solder connection on the effector either. Still not sure where the issue is coming from but definitely a connection issue.

I have another effector coming for another project so I will toss it on the printer in hope to eliminate that as a possibility.

Will update when I have more info.

Thank all!

@Carlo I will give it a shot but I suspect this is not an issue as it does probe the first few point just fine and when it fails it just keeps driving into the bed.

@Veti Agreed. I can get it to trigger consistently. Just fails at the one point during auto calibration.

I have managed to get it to do a complete auto calibration once or twice but that is it.

@Veti Yes currently running 3.2. The beg.g was created by the configurator.

This from a fresh power on. Not sure if that makes any difference.

Thanks again for the assistance.

@Veti Thanks for the reply. They are not the results, I am not able to get the auto calibration to complete. There is no M501 as there is no config-overide.g file.

These are the setting from before. They are slightly different as the effector and carriages have been changed.

M665 R183.65 L380.5 B150 H464.03 X0.01 Y0.16 Z0.00  ; Set delta radius, diagonal rod length, printable radius and homed height
X0.16 Y-0.26 Z0.10                                  ; put your endstop adjustments here, or let auto calibration find them

The whole thing is strange. I can physically move the head around and tap it on the bed and it triggers every time, but as soon as I try to auto calibrate it never triggers on the 7th point.

So I have a delta printer that has been sitting around for a while and decided to get it back up and running. Was running with the old Duet 0.8.5 and the IR sensor. I replaced that with the Duet Mini 5+ and a Smart Effector.

Tapping the bottom of the effector triggers the green light so seems to be good there. Set H30 in the M558 command to be safe.

When running the G32 command it hit the first 6 points with no issues every time. When it moves to the 7th point (P6) the nozzle crashes into the bed ever time, no green light. I changed the sensitivity to 40 and still does not trigger on that one point.

I have managed to get this to work only once.

Here is my bed.g.

I am at a loss as to why it does not trigger on that one point.

@MikeGeppert said in Duet 3 Mainboard 6HC and 1LC ToolBoard:

Couple comments about the Tool Board I learned:

1. It only supports 12V fans. While you can feed 24V in and support a 24V hot end, it will only handle 12V fans without modification. I ended up running a wire to the 24V in to support the Hot end fan and it works really well. I replaced my 24V part cooling fan with a 12V version just to make it easer to hook up. I am actually considering getting a 12V fan for the hot end just to get away from the mod I had to make.

2. The Tool board does not support Auto tuning the hot end yet. This is really a pain. I ended up running both the temp sensor and the Heater to the main board and running the auto tune then copying the results; then hoping the numbers would at least be close on the tool board.

In the end I ran into Extruder issues so I removed the tool board and ran everything to the main board. I still have extruder issues now, so once I get over that I probable will go back to the tool board.

Thanks for the information.
