no spi communication for drivers - missing PA6 #23

Closed SaPu84 closed 7 months ago

SaPu84 commented 1 year ago

I get a new H723 and find a broken spi1 connection on the PCB to the driver. Workaround is to use PA6 of EXP2 and connect it to the driver line by using a jumper cable. May it run into other electrical issues by doing it?

MAX31865 is working fine.

jmeier5261 commented 1 year ago

Noted the same on my h723 v1.0.1 octopus pro. Drivers do not appear to connect to spi bus pa6 pin. MAX m31865 works fine but there appears to be an error on the pcb itself and the driver sockets are not wired to pa6. If I run a jumper from PA6 to the driver pin it works as expected. @bigtreetech was this fixed in a later hardware revision or just a bad batch of boards?

kmobs commented 1 year ago

Any official word on this?

jmeier5261 commented 1 year ago

Nothing official just return the board to the vendor for a replacement if possible. There’s a bunch of these dud boards out there.

kmobs commented 1 year ago

Thanks. I ended up just tapping into the LCD pin like y'all said. This + the fact that it enables the heater pin in DFU makes this board extremely disappointing. I won't be recommending it to anyone.

bigtreetech commented 1 year ago

The diodes used previously were not very high in parameters and there was a chance that they would break through when the customer was using them in a harsh environment (high static, humidity, etc.), resulting in a failure to communicate with the driver SPI signal. We have now addressed this problem.

kmobs commented 1 year ago

I'm sorry but I don't know if this is the case? I never had communication on the bus.

How have you resolved the issue?

NAPCAL commented 1 year ago

I have checked both of my Pro boards and found no continuity issues with the SPI1_MISO or Drivers MISO. Here is what I checked on my F446 & H723.

Same... brand new out of the box Octo Pro with 446, no SPI1.

@csdstudio78 Can you verify that your U27 and D41 are facing the same way as in my photo?

csdstudio78 commented 1 year ago

To add, connecting stepper drivers to PA6 via EXP2 enables spi1. So PA6 is connected somehow, just not through the intended path to the steppers. lol

NAPCAL commented 1 year ago

@csdstudio78 Thanks for the photo; it seems to be a revision of the PCB that the trace between D21 and pin 6 of U27 is incorrect.

My good board has the trace, and the bad PCB has D21 going to a via, but it doesn't seem to connect to U27 pin 6.

The PCB manufacturer may have made this error on the current batch of PCBs.

csdstudio78 commented 1 year ago

Ahh yes. OK. Thanks for confirming! I definitely have a bad board... I've already requested a replacement via Amazon so we'll see if that one is any different. :) If not, I'm contemplating fixing this one. Is it just missing that trace or is it incorrectly traced to something else? I can add a missing trace.

NAPCAL commented 1 year ago

I forgot to post the board version of my good boards. @csdstudio78 Could you check and post your board version?

Mine is 1.0.1 as well.

csdstudio78 commented 1 year ago

OK... I hate to burst our bubbles, but I went back today and looked at my board again, knowing what you were looking for, and with the camera flash there's definitely a trace. Time to do some more checking. @NAPCAL

NAPCAL commented 1 year ago

@csdstudio78 Any chance you can ohm out the paths?

The jump wire from EXP2 MISO to the drivers leaves the STM unprotected by D21.

If you can find the failure location I can check mine.

Agreed. I'll pull my board today and look. I don't like using exp2 either.

OK. All traces check out. Power checked at 3.3v, 5.0v, and GND, all points verified in the schematic you posted above. Diode checks out, all resistor values checked. Because I'm not an EE, I can't figure out why this doesn't work other than not understanding U27. (its role and whether its oriented correctly)

csdstudio78 commented 1 year ago

@NAPCAL See below... am I wrong here? I don't understand the output vs input, if MISO (PA6) is an input to the MCU then the diode is backwards. If PA6 (MISO) is an output, then U27 is backwards. Either way, one must be backwards.

EDIT: Looking at the 3.3v input to the buffer, I'm certain MISO (PA6) is an input to MCU leading me to believe the diode is indeed mounted backwards. This leads me to ask, why is a diode present on an input?

EDIT2: After further study, I'm likely wrong seeing that PA6 is being pulled high and U27 pulls it low, so perhaps the diode is correct? See... I'm not an EE. :)

NAPCAL commented 1 year ago

@csdstudio78, the circuit is a level shifter for Master In Slave Out from the drivers @ 5V; R203 ensures the input to the buffer never floats; R205 is a 3.3V pull-up to also ensures that the STM (3.3V operational) input never floats; U27 is only to translate low signals through to the STM SPI1_MISO pin 42 by the use of the D21 in a reverse direction (DIODE SCHOTTKY 30V 200MA).

image

NAPCAL commented 1 year ago

@csdstudio78 Also, note the other SPI1 signals go through U26 of the same type of device, and it is connected to +5V, so the +3.3V signal from the STM will get stepped up to +5V. It is when you are stepping down that the extra components are required.

csdstudio78 commented 1 year ago

@NAPCAL ... Ok, I'm tracking now. So the schematic is good and the physical layout appears to align with the schematic. We're running out of options.

NAPCAL commented 1 year ago

Bad U27 since it only is used for SPI1_MISO or D21.

csdstudio78 commented 1 year ago

Forward bias of my diode (D41) is 0.27v, resistance is 92k. Negative probe on the left side, towards U27. Reverse bias V is OL, resistance is 7M.

csdstudio78 commented 1 year ago

@NAPCAL Your rev 1.0 readings are similar to my rev 1.0.1 readings above for the diode. Just to verify, you're checking D41, not D21, correct? BTT TMC5160 Pros work ok with MISO jumped to PA6 on EXP2. I initially dropped in a set of new Fysetc QHV5160's and both sense resistors on one driver blew within a few minutes, current limit set to 1.5A, motor voltage at 50v...lol.

csdstudio78 commented 1 year ago

Alright! I'm getting somewhere. Board rev 1.0.1 SPI1 works as long as there's no display connected to EXP2 (Small bummer). There's some sharing issues with SPI1 on the Octo Pro that aren't present on the non-pro Octo. The non-pro Octo board doesn't have the level shifting logic, it's straight from stepper driver to PA6.

EDIT: My display only uses PB1/2 on EXP2 so that's an easy fix.

NAPCAL commented 1 year ago

@csdstudio78 Well, the wire jump would cause a pull-up to +5V due to the drivers at +5V logic (MISO) and the EXP2 (SPI1_MISO) at +3.3V; without the wire jump, the display seams to pull the logic levels into a between state even though doesn't use (SPI1).

Is this the final solution? I have a 1.1 board I am trying to get up and running with 5160's and I don't think they fixed this issue with this revision. The pins have been swapped around though so that the heater is not on during DFU mode

NAPCAL commented 1 year ago

That is a temporary fix, but we need to get everyone that has to do this to get their TMC5160 or other SPI TMCs, to contact BTT support so they can see it is a problem for board owners.

If display connected to EXP2 I can't do anything with motors (spi errors in console). Even homing.

If I disconnected display it makes homing wo errors.

I printed 3 times with display. But after last turning on the printer it doesn't work with display anymore. I tried several new BTT 12864 mini (v1 and v2).

As I saw from other forums Bigtreetech provides bad customer support (example on their forum https://community.biqu3d.com/topic/665-bigtreetech-tmc5160-pro-v11-and%C2%A0bigtreetech-btt-octopus-pro-f446-on-klipper-spi-not-working/). I wrote them 1 year ago about another product - 0 answers.

I will open ticket. But I have no hope for quality support from this Chinese company.
