Important things to know regarding stepper upgrade with TMC 2130 with SPI

Hi,
Had a lot of troubles upgrading to TMC 2130 v 1.1 using SPI, and after some hours, reads, tests, here are the MAJOR things to take care to success 100% this upgrade:

1st : Disconnect the 3 jumpers originally plugged on the Mother board , Under original steppers. Other way, you will blow the TMC2130 immediately and never see, you just burn your stepper board. Take care on that, happened to me.

2nd: Use only and exclusively Arduino v 1.8.5. Other way is hazardous and request some teawks . Follow the excellent videos in 2 parts provided.

3rd :Don't forget to erase internal RAM of motherboard after flashing: M502, then M500 with pronterface.

4th:  Execute the commands codes commented (like on the video) using pronterface to check all is fine. Take care here, my first try with blowed steppers (after my error not unplug the 3 jumpers), reports me all is fine, and allow me to adjust the tension correctly). So enven blowed, all seemed to be fine, but NOT : no X/Y mouvement.

5th: adjust the right voltage for each stepper.

6th: you need a cooler fan for the stepper Inside. This is mandatory.

Finally, you just need to use 2 steppers for X/Y motors, that's it; Z/E0 is a waste of money and not really relevant.

All these conclude my success upgrade with TMC 2130 SPI installation : 100% working.

Now, I'm totally conscient jumping to new firmware with the last release of Arduino will request new detailled topic to make. 

For thoses who want to go further and play with sensorless function:

    Thanks for the valuable post Enrique - I will have to add these tips to the wiki!

    Hello Enrique,

    if i forget to run m502/m500 commands after upgrade, the drivers fill be fried, or there is a chance that they will survive? This happened to me.

    The commands should be executed in pronterface or it is fine to do that in arduino ide through the teminal?

    Don't you think the upgrade of extruder and z axis may be useful to get the sensor-less mode working for them. This mode detects the load of the motor and sends 'no go' signal in case of an obstacle. This way the z motor will (theoretically) never be able collapse and scratch the heat bed in case it is incorrectly leveled. For extruder it may help preventing the filament grinding. Right now when the filament is loaded, once it reaches the hot-end the extruder motor still tries to bush it forward for some time, which results in filament grinding. Or even worth thing, when you press change filament on the screen, and instead pulling it out first you pulls it in, the extruder starts to push the filament as a crazy into hot-end. This could be avoided (again theoretically) by this motor load detection that provide those tmc2130 drivers. I understand, it would be better to modify a software to disable pulling in the filament option, before you pull it out, but this is how unfortunately it was designed in the software by Chinese producer. 
    Again, this is a theory, i have never tried it. I would like to know your opinion or may be somebody else has already experience with sensor-less mode.

    Thanks

    Andrei

    Personnally, not yet tested SPI without endstops (seems in theory to work, but request candidates to validate). My thoughts and reads brings me the idea, it can be usefull for X/Y sensors axes, but not for Z.  Again not yet tested. Probably on my third printer who is somewhere travelling with GEARBEST. I will do that for test purposes only. What I'vez done on my 2 Jgaurora : 2x TMC2130 for X/Y + 2xTMC2208 for Z/Ext0. But results for Z/Ext is the same with standard drivers or 2208. More soon.

    Thanked by 1Andrei Shekhau

    Hello Everybody on the group, this is my first post here :-).

    I have JGaurora on the way to me, expect to get it in 3-4 days, and without touching it yet consider the modifications :-).
    Driver as the first to change.

    Regardless we speak about 2130 or 2208 if it is bus interface wired - how we should to adjust the currents with the potentiometers if it is also adjusted by software? Understand potentiometer is over the software, it means it is just like hardware general limiter that cannot to be overed by software settings. So if we'll set with pots 700mA then can't set by soft 800mA, isn't it?. So in practice what the current (or voltages) should be set to be safe for steppers/drivers and to let flex adjusting by the software?

    Second question is: JGaurora has max speed 100mm/s (datasheet). So what is the sense to set hybrid threshold over that the mode will be changed from stealthchop to spreadcycle as 100ms. It will be never reached and machine will always work in stealthchop mode - is it just the idea to keep it always in this mode?

    brgds

    Welcome @netzmark :smile:
     
    My 2 cents: the speed limiting factor will likely be the extruder - the long bowden tube will limit your print speed to ~60mm/s.

    Hi Samuel
    yes, if it is also worth to replace E driver at all - oppinions about it seems be different in the net.
    But specialy in this case setting the threshold to 100ms seems be totaly senseless so...

    Hi everyone!
    I'm joining the topic. A few days ago I recived a package from aliexpress containing TMC2130 stepper drivers. I'm very eager to get to work and after abuot two days of fighting it looks like everything is working as it should. When I finally assembled the printer's housing, I checked the leveling of the heated bed again and started the first printout of the test cube 20x20x20mm.
    Of course, the printout fails because there is a shift od subsequent printing layers in the Y axis. I used the 2130 stepper drivers for the X and Y axes only. I set the voltage at the TMC 2130 to ~1.0V.
    Does anyone have any idea to solve this issue? What is going on? What did I do wrong or what I forgot? What's next?
    So many questions, no one idea. :smile:

    Edit: I forgot to say about some important matters. I read the forum here where AETEK gave voltage Vref for the X axis - 0.85V and for the Y axis = 1.25V. With this setting for the Y axis during heated bed movement and reaching the maximum position, a horrible sound appears and the motor is still trying to rotate. Decreasing the voltage Vref to the level of 1.1V doesn't change anything. Only values around of 1.0V give the proper work of the Y axis.

     Hi and welcome. Do you have a fan cooling the stepper drivers?
    Thanked by 1coldpeet
  • coldpeetcoldpeet Posts: 3Member
    Unfortunately I don't have a fan. Only standard heat sinks. Today it is almost midnight, so I'm going to sleep. Tomorrow I will try to assemble something and cool these stepper drivers.
    I focused so much on the changes in the Marlin software, and I forgot about such a mundane matter.
    I will describe the results of my struggles here - Unless it is spamming the forum.

    By the way, I'll ask if after installing the active cooling should I use the suggested voltages Vref (X axis = 0.85V and Y axis = 1.25V)?

    Hi, sounds maybe you have a wiring issue with one of your drivers. First step: mandatory to place a fan directed to heat sinks.
    Have you keep off all the jumpers under the TMCs?

    The fact you hear horrible noise from one motor, is a sign of Under/over power the stepper motor.
    Check again all from scratch step by step. No Reason not to work.
    Finnally: have a spare TMC if you have a doubt: Simply to exchange.

    Hi Enrique!
    I've checked the wiring several times, I'm sure it's okay. In fact, initially the CS pin in the X axis wasn't good, but I corrected it. Jumpers under the X and Y axis controllers are removed.
    Of course I have spare drivers (3 pieces).
    Today I'll continue to work on this topic (my wife isn't happy).
    If I manage to get through all these difficulties, I'll try to reasonably describe the reasons for these errors and the solution.
