Z-axis moving too little?
Dear fellow RepRappers, I have built a RepRapPro Mono Mendel which is my first ever 3D-printer. I print PLA at various temperatures (I have tried 180-225°C) on heated glass using a 0.5 mm nozzle. The...

If the potentiometers on the stepper motor drivers are not adjusted correctly, after a while they will heat up and give you some strange errors. I would suggest feeling them while the printer is...

Checking your pots is a good start as you just may be missing steps. Also make this check (hopefully you have calipers...a ruler can get you pretty close) Home your Z axis. Then, use your manual...

I have the same problem and have not solved it yet. Interested in replies to your questions.

Thanks you for your suggestions. I have got myself an indicator now so if everything goes well I should be able to measure the z-axis with a precision of 0.03 mm. Hopefully time will allow me to...

I made some quick measurements tonight. I will make more next week but here is my current findings: The motors do not get warm. The carriage is homing to the same height consistently. If I, after...

It's the stepper motor driver on the circuit board that will get hot if the potentiometers are not set correctly.

Yes ofc, sorry. They are not much hotter than room temperature.

I have now installed two nuts instead of one nut and a spring on each threaded rod. The backlash (hysteresis) problem seems slightly better but the steps are still wrong. I tried moving from the...

Another update: I have tried increasing the steps/mm just to see what happened. I increased it with 80 steps/mm which should give me an additional 0.2 mm after 1 cm. Surprisingly the test print I have...

Seems like it could have been an adhesion problem. I did not expect the print head to drag the model with such force. I started using hair spray and now it seems to work. For anyone reading this and...
