This tool should allow you to migrate a very old Configuration.h files to the current code base. If you have a printer with a very old version of Marlin, this should make it much easier to move your...

So, I stumbled on this part on aliexpress. You could attach a GT2 tooth there. The signal is transmitted via twisted pair interface, so quite immune to noise IMO. I am going to try develop a...

It depends on what you are trying to accomplish. If you want to use the encoder to position an axis, you probably need to be working down in the Stepper.cpp module. But if you just want an independent...

nope. everything is tight. ive checked all belts and set screws, all are tight with no slack at all. Belts make a nice tone when plucked.

Well... The various extruders and the heat bed are all done with a PID algorithm. The stepper motors are not PID, but there are a fair amount of calculations being done to get all the motors to...

Right, there is room for more math on a cartesian printer, but don't forget the Deltas and CoreXY.

Ink jet printers have obtained super resolution by using linear encoders Optical strips on axis read by sensors provide very accurate measurement So even though you sense that the position is in error...

Cozmicray is right, the encoder resolution has to be better than the steppers. Which means tons of interupts to deal with. ( You can't try to poll the encoder ). The better way is a separate cpu that...
