Thanks for the detailed response! EDIT: I didn't have the +5V pin hooked up on the stepper driver socket in my printer. Apparently, while the unit will turn on, hold...

Ah, ok. So I didn't have 5V run to the driver's socket, so the little adapter board wasn't sending said +5v to the S42B. I checked that I could talk...

Still sufferings inconsistent connections. Sometimes it doesn't work without being plugged into printer, sometimes it doesn't work IF it's plugged into the printer, I'm getting a replacement programmer but I...

Ah, thanks again for a good answer. I'm unfortunately reasonably versed in PIDs, but have never had a case I COULD just tune like that. I guess the problem is...

There's no absolute reference (i.e. the belt could slip a tooth, and it only knows where it is within a given rotation) - you might be able to run it...

Yeah - with the boards that have CANbus, you could run them like trinamic drivers. I know they talk serial, but I don't know if they entirely commanded that way...

Agreed - and for extrusion, I don't see much value in closed loop. Maybe I'm missing something. If the set up is even close to right, it'll just shred the...

You're saying the advantage to closed loop is being able to run lower drive current? Huh. Well, I was all prepared to call you crazy, and I don't think it's...

I believe this is an issue with not having the PID values tuned for your printer. What happens is the motor turns to position, the bed hasn't QUITE gotten there...

1) I was using the Skele for at least a year before switching to TZB extruder. Aside from the Skele being cooler since it's open and geared, I didn't find...
