@phaedrux said in Burnt effector:

Are you able to test the heater cartridge itself (carefully) to see if it's still functional?

Just to confirm that you are using a 12v PSU with your 12v heater cartridge? Had it been functioning correctly for some time before the fault?

Did the heater cable have strain relief? It's possible there was a weak crimp or cable causing a poor connection and increased resistance leading to the heat.

Yes it is 12v, it has been working for 4 years, no problem.
Sonetimes the heater wire broke near the molex connector because i don't have strain relief (i don't know where to buy it). So i put some electrical tape around the wires.
This time the wire was ok.

Now i soldered the pin back and everything is working again, but I'm afraid it could hallen again... I'll buy a new molex connector and crimp again all the wires very carefully.

@phaedrux I bought it in 2018 on reprapworld.com,
I used the original wires of the heater.

While i was printing the temperature dropped down and it have me the fault heater message. It happened two times, i tried printing a third time, but it didn't heat up.

@ulcast what heater are you using? voltage? wattage?

Original e3d heater 12v 30w.

Hi, i have a problem with my effector. Some days ago instarted having problems with heater faults.i checked the cables and they were ok. Yesterday the heater didn't work at all. I disassembled everything and found the effector as you can see in the picture. Why has this happened?

Hi, i have a problem with the smart effector.
It Is the third time that my hotend wire gets broken in the smart effector plug ( you can see it in the photos)
The wire is standard from e3d hotend, and it is quite stiff.
What can i do to solve the problem? Do i need a more flexible wire?

Thanks

S6 worked!
It adjusted all the measures and now the object are ok.
Thanks!

The real arms length 276mm, but I changed it to 251 to get correct size objects.
I measured R and was more or less 133mm. I measured it again now and it seems to be more 138mm.

This is my bed.g

; Use S-1 for measurements only, without calculations. Use S4 for endstop heights and Z-height only. Use S6 for full 6 factors
; If your Z probe has significantly different trigger heights depending on XY position, adjust the H parameters in the G30 commands accordingly. The value of each H parameter should be (trigger height at that XY position) - (trigger height at centre of bed)

yes they are parallel, i used duet boards to mount the magballs on the rails.

Hi, I have a problem with the arm length.
I made them the exact same size as the original anycubic rods (267mm from center of the Magballs).
The problem is that if I put 267mm in the firmware, it prints smaller objects (on x and y. Height is correct)
To have an object the correct size I have to lower the length in the firmware to 251mm.
But I don't understand why.
Do I have to change the carriages? I still have the original ones
