For those of you who have used the Silent Stepper Drivers (TMC 2100) have you ever used the stealthchop mode? Working on a project with them and can’t decide whether it’s worth adding in a jumper for them as the drivers are currently set to stay in spreadcycle.
Poll is only for people who have personally used the drivers please.
Would love to hear experiences and feedback as well.
The TMC2100s from Watterott are in stealthchop mode by default, the jumper is for spreadcycle if I recall correctly. Stealthchop mode is prone to losing steps unless you’re driving them slowly.
@ThantiK I have this problem. What print speeds will be ok on stealthchop?
35mm/s and below…maybe. This means travel speeds have to be that too. This may be higher, I’m not sure. I was using mine on a delta so a move could mean that near an edge, a carriage would be needing to move faster than that to obtain that speed @ the end effector.
Ok, Thanks. I use stealthchop because of squeaky sound from the steppers. Maybe someone can recommend good steppers to use with TMC’s without using stealthchop?
My TMC2100 is in “drawer mode”… I was looking at a guide with a step by step description how ti install and setup the TMC2100 to be compatible with A4988/DRV8825. By now I keep my well preforming DRV8825 and have the TMC2100 in “drawer-mode” wiating for the guide 
I use my two TMC2100 for X and Y with the standard mode (stealthchop) that came from watterott. (CFG1 CFG2 and CFG3 open). CFG6 (enable pin) is also unconnected. Power supply is 19V, and I never had one missed step, no matter how fast I run it. Print speed is usually between 45-55mm/s and move speeds around 100-120mm/s. I also tried to manually brake it with my hand to see how hard is to get it loose steps, and boy, I had to really push it.
Oh, and my printer is no feather light either. Motor currents around 1Amp with proper cooling.
@Romeo_Pavel What steppers do you have?
@Johnny_Linden lol, drv8825 and “well performing”. – https://hackaday.com/2016/08/29/how-accurate-is-microstepping-really/
Thanks all. You have convinced me to add jumpers for stealthchop at least for the time being.
@Daniel_Kusz I have two different steppers for X and Y. The X is NEMA 17 17HD40005-22B and the Y is a NEMA17 17HD60001-22B because Y has to move the X gantry with a lot more mass on it.
A lot of driver modules are dependent on the actual motor attached, too little or too much inductance changes how well it runs. Running at 12V vs 24V makes a difference too. So the driver configuration matters.
