Toolboard 1LC troubles

@oliof it's Bondtech BMG with Bondtech pancake motor (https://www.bondtech.se/product/nema17-pancake-stepper-25mm/). Never had issue with it, but now motor does not extrude consistently.

@Arminas the TDS gives peak value of 0.7A, so I would set it to something from 550 to 600 mA in RRF. If that does not improve its behavior, measure the resistance of both phases; if they differ too much the motor may be toast.

@oliof both phases has 4.6 ohms, although it's written that it should be 4.2. Is that an issue?
-
@oliof But if I connect the wire and measure phase on the loose end of wire, one phase is 4.6, another is 4.9
-
@oliof After a few layers extruder starts to skip the steps, and it gets extremely hot, I can't keep my fingers on it. So I guess it's motor fault?
I tried to swap to another motor, will see how it goes.
-
@oliof @droftarts same issue with other motor - during the print, something happened and blower fan started to blow 100% instead of 20% and I got an error "M106 board 121 does not have fan 0".

@Arminas what does M122 B121 report when the fan goes missing?
-
@oliof So I tried to print one more time. This time there is no fan error, but extruder motor started to skip steps and it's over extruding a lot, line width looks at least 2x wider than it should be. Now I am thinking that it skips steps because of the huge over extrusion.

@dc42 maybe you have any insights?
-
@Arminas is the blower fan that goes to 100% the hot end heatsink fan, or the print cooling fan? If there is a temperature reading error on the hot end then it's normal for the hot end heatsink fan to go to 100%. The firmware does that because it doesn't know what the temperature is, and having the heatsink fan on may prevent the hot end from clogging or getting damaged.
My best guess is that either there is a problem with the temperature sensor, or the temperature reading input on the tool board has been damaged by either a short circuit between the thermistor and heater wires, or by electrostatic discharge. So I suggest you start by checking the thermistor using a multimeter. Check that its resistance at room temperature is as expected, and check that there is no continuity between it and the heater wires. If that looks OK, try using the second temperature connector on the tool board. Make sure that the hot end metalwork is connected to Duet ground, either directly or through a resistor, to prevent static charge from building up.

@dc42 it's the blower fan. Temp sensor is good by checking it with multimeter. Is it possible that toolboard temp reading input is damaged and it causes the toolboard to do weird things, like over extrusion and etc.?
What do you mean by checking the continuity between temp sensor and heater wires?
Hot end metalwork is not grounded I guess. How do I do that?
-
@dc42 Same happens with second temperature connector. It just starts over extruding out of nowhere..
idk if this helps, but here is M122 B121:

@Arminas said in Toolboard 1LC troubles:
MCU temperature: min 41.9C, current 71.1C, max 76.4C
Are you using a heated chamber?
-
@Phaedrux no, this printer is not enclosed. And I have one more RatRig Vcore 400 printer with 1LC, but this one is enclosed and there are no problems
1LC temp readings on enclosed printer are the same:
MCU temperature: min 19.6C, current 72.4C, max 75.2C -
Those temps seem very high for a non-enclosed printer. Can you share some photos of the setup?
-
@Phaedrux Sure, here it is.
-
Can you tell if there are any components on the board getting very hot?
-
@Phaedrux Blue - cold, Red - hot (I don't feel comfortable touching it more than 3 seconds). And extruder motor is very very hot
-
Can you disconnect the motor and anything connected to the IO connectors, and see if it still gets hot?
-
@Phaedrux one of IO is used for BLTouch, I can't start the print without it. Maybe it's not a big deal if I leave this one connected?
