Re: Use tmc2130 without spi in stealthchop

The GT2560 is based on the RAMPS. If you leave all jumper on the board MS1, MS2 and MS3 are connected to VCC. So if you left the all Jumpers in place and the CFG2 pin on the TMC2130 as well your CFG2 was not open but conected to VCC and CFG1 was conected to Vio as well resulting to run the driver in...

Re: TMC2130 and motor overheating

You write that you are running your TMC at 800mA which is Irms and results into Imax of Irms × 1.41 = 1.12A so either reduce your Irms because you'd running those 0.9A over their current rating

Re: TMC2130 and motor overheating

1. Heatsinks and active cooling are a must on the TMC i my opinion. At least that is how I run all my 2100,2208 and 2130. 2. Concerning the hot stepper motors. What type of motors do you run concerning max current per coil. I had me some issues with 0.9A steppers overheating. Replaced them with 1.7A...

Re: Use tmc2130 without spi in stealthchop

CFG2 PIN does not have to be removed. As it connects to the MS2 Bridge. If no Jumper is on the MS2 on the board the pin is left open. The high pitch sound you encounter in spreadcycle is most likely due to a stepper motor with high Impendance. You can reduce or even get rid of the pitch noise in spr...

Re: Use tmc2130 without spi in stealthchop

This is the SPI Bridge that you have to solder close in order to set the 2130 into standalone mode http://up.picr.de/31586310qe.jpg For stealthchop ths pin has to be left away http://up.picr.de/31586311qd.jpg like this http://up.picr.de/31586323jz.jpg Private Message buttons http://up.picr.de/315863...

Re: Use tmc2130 without spi in stealthchop

Depends which TMC2130 sou have. If Watterott you have to close the SPI solder Bridge in order have them in standalone. In order to have stealthchop in standalone enabled if the pins are already presoldered you have to cut or desolder the CFG1 pin. Kannst mich auch per PN in Muttersprache kontaktiere...

Re: tmc 2130 for newby

Which Firmware are you on? Sensorless Homeing requires the the TMC2130 to be in spreadcycle Mode. So not exclusevely but at least for the homeing process. In stealthchop sensoless homing won't work at all. In Marlin the switch to spreadcycle for Homing is integrated for X and Y if setup correctly in...

Re: tmc 2130 for newby

First you shouldn't use sensorless homing on Z min on a carthsian printer as with the threaded rods you apply to much torque and might damage your hotend. Second if you have dual stepper on Z you might think on wiring them in series instead of parallel. Have you configurea dto run the TMC2130 in spr...

Re: Anyone tried Klipper?

I'm running Klipper since a few weeks not as my main firmware but swap it for testing. At the moment there is much going on and Klipoer is more than just a beta right now. Recently support for multi extruders has been added. One feature that is currently missing or better to say needs some tweaking ...

Re: TMC2208 - MKS 1.4 - Anet A8 ?

In standalone mode they operate only in stealthchop2. If you want to use features as setting Vref through code or switch to spreadcycle you must either use a FDTI Programmer and program the driver over OTP or set them up and wire with UART and software serial. Which is not that hard if you want both...
