I’m a bit new year. Got my Genesis in February and have been slowly building as I have limited time and only on the weekends. Today I tried the first movement commands with generally positive results.
- All the motors work in both directions
- I can reach all points of my bed
- I can home and calibrate my Y axis and my Z axis
However, I can’t home or calibrate my X axis. While the Farmbot will happily move to either end, it simply never detects when it hits the stops (the metal stops that come with the farmbot, not DIY endstops or anything). I get errors like:
x-axis timed out waiting for movement to complete
I’m not an expert on stall detection, rotary encoders, or current sensing stepper drivers but thought I’d put those in as keywords.
I am not sure if its related but for completeness, my voltage indicator is yellow.
I appreciate any help in advance!
Could you share your hardware settings found on the device page?
Is your X-axis encoder working properly? Here are additional information how to check and troubleshoot: Are my encoders working?
Maybe the axis does bounce back from the endstop which leads to too many successful travelled steps, so it does not detect that it’s stalling. That might be caused by a loose belt or something similar.
I’ll have a look. Thank you! The bounce sounds very plausible (but I’ll check encoders too) because I was intentionally loose with the gantry wheel plates based on the recommendations in the instructions that you can always tighten them.
Thanks again. I’ll let you all know what I find.

@RickCarlino - thank you. I did buy from Farmbot and have used your [awesomely amazing] support. Marc has been fantastic on that front. I also wanted to try to use the forum some in the hopes that others having the same problems will benefit.
I only get one day a week or two max to touch my Farmbot and it rained all day yesterday. Today I checked my encoders. Visually everything looked fine but the encoder data was always 0. Also, speed didn’t matter and stopping it using my hand didn’t matter.
I thought “bad encoders” . . but then I inverted my X encoder as suggested on the link you gave. The fact that I instructing my X axis to go 10 mm resulted in only 3 little nudges told me my encoders were working. I un-inverted and moved to the mechanicals.
I tightened my gantry plates which I intentionally had loose-ish. That didn’t solve the problem.
As soon as I tightened my left X belt, good things started to happen. I saw encoder data and was able to find my X home and calibrate X.
Thank you again for all the help!! Now on the next step (at least next Saturday I will be).
