This covers TMC2130 and 2208
Wire Via SPI for Stealth Mode
- Solder certain bridges on the driver - not easy
- Change Marlin code in configuration_adv.h
- Need to change pins_RAMPS.h file to tell which pins are being used
- Debug allows M122 in serial monitor for status
- Define sensorless_homing in config_adv !!! This is useful.
- Disable endstops_pullup for sensorless homing
- M914 in sensorless homing determines sensitivity of sensorless homing
- Need to upgrade to Marlin 1.1.9 from 1.1.0 to do sensorless homing.
Analysis of Torque
- According to test results at 36V - the torque is great in Stealth Mode up to to 250mm/s - [1]
Wiring Detail
Source 1
- If smart controller is on Aux 3 - need to wire into Aux 2 headers - see Step 4 at [2]. Disclaimer - author questions validity of LCD working with TMC2130
- Covers 3 parameters set in software - sensitity to bump stop; holding torque; conversion from 16 to 256 microsteps
- Stealth chop gets you less power - how much less? Less speed. Unacceptable for fast bulk prints on large printers
- Can run in hybrid mode to set Stealth mode only below a certain speed, and high speed is noisy.
- Nothing about solder bridge on the driver to select mode?
Source 2
- Chris Riley - [3]5
- Step, Dir, Enable pins face down [4], 4 pins up. Diagnostic pin goes up [5].
- Sacrifices LCD for this install. SDRAMSP supports is commented out [6].
- Diagnostic pin goes to the end stop signal (rightmost). So effectively, we have to solder one pin on the TMC2130 to replace the end stops. That is worthwhile.
- Set x and y home bump to zero when using sensorless homing in config.h - [7]
- Install the TMC2130 library via Sketch -> Include library -> Manage libraries... But which version?
- Need cooling fans - [8]
- For the pins that we reassign - make sure you don't steal them from EXT2 if you are using the second extruder steppers [9].
And What About TMC2208?
- TMC2208 disadvantage - requires active cooling, but so does TMC2230 - [10]
- Swap motor direction by reversing 2 outer pins on either side, or reverse in Marlin Firmware. (just plug reversal in Marlin?)
- If you have Marlin <1.9, that's it. But Marlin 1.9 and up, need to select the drivers that you have to TMC2208 (selection is not avilable in Marlin 1.0)
- Yes! Drop-in replacement that is quiet, with Stealthchop2. [11]. Requires no firmware upgrade if using <Marlin 1.9. Question is if the torque is acceptable.
- TMC2208 Instructable - [12]
- Yes, can get quiet operation as drop-in replacement, no modification needed outside of small firmware change, but not sensorless homing. [13]
Links
- Marlin docs on TMC2130 - [14]
- New: Marlin docs including TMC2208 - [15]
- Hackaday post - summary is that it's a job to configure properly - [16]
- Prusa forum - good list of references - and explanation of low torque is 12v operation instead of 24 or higher. 1A at 24V only is required to run all stepper motors??? [17]. See first response, Hardware point #9.
