I want to add this post in hopes that it helps up-and-coming FarmBot-its avoid a pitfall I think I fell into…
In the early days of setup, I think that I installed and tested the belts in a manner that led to some damage that is having impact to this day.
Soon after installing the FarmBot, I was eager to “kick the tires”. I fired up the robot and was soon sending commands to “move here”, “move there”, “move everywhere”. At this point I observed that FarmBot was having problems. It would stall, skip, make funny clicking noises, not do what I had told it to do.
After much observation, conversation, adjustment, tweaks and a bit of grease (both white lithium & elbow) I was able to get the FarmBot to move as instructed. However, in the early days, with all the slipping, the X-axis drive belts took some damage. (see vid clip at:
Just in case the link does not work in the forum, try cut-n-pasting this:
I was able to do a short-term fix by moving the damaged portions to the far end (from “FarmBot Home”), thereby allowing us to seed & water the front 3/4ths of the planter bed.
I believe the only true fix at this point is to replace the belts…
If I had to do it again, I would be VERY careful of applying tension, strain, and torque to the drive belt system until I fully understood (and appreciated) the physics and dynamics of the drive system. I would start with everything looser & better aligned. I would only perform very short tests. (I had a few “just let the motors run and see if it “powers on through”” moments that I really regret).
I hope this post saves at least one, if not more, folks from the same experience (a $140 lesson - the cost of two new X-axis belts)
