?I have implemented your DIY spring load worm design. The mod went really well with the drill jig you 3d printed. Tracking appears to work well
with no binding but I am having trouble with guiding. Especially with the DEC. I have attached an image.
SO I am using MAXPCB OnStep v3.16 (steppers TNC5160, motor 9 deg, 400 step) right now I am direct coupled but I have 3d printed and modified rockmover's design. I though I would first try to get
some results with the direct coupled first. It tracks reasonable for a few minutes but than the DEC goes wild.

1. Can you share how you tune your design. DO you tighten the springs; such that there is no movement at all
2. What are your PHD2 guiding algorithms and parameters.
3. Do you use resistive switch on the DEC and do you use backlash settings in PHD2.
4. What is your OnStep version (and drivers and PCB)? and do you set backlash in the OnStep config file?

Thanks for any help and guidance,? Brent
