Tools and Gantry


#1

I realise the maximum weight the tools can be is 2kg, Is this limited by the gantry system of the motors? How can that be increased to about 5kgs?


#2

The maximum weight of a tool is probably closer to 1kg, and is mostly dependent on the strength of the magnets that hold it to the UTM. If you developed a UTM that connected to the tools more mechanically, then your limiting factor would probably be the z-axis motor.

In general though, FarmBot isn’t a heavy-duty machine and isn’t designed for heavy tools or tools that would need large forces to work (such as a plow).


#3

Could you provide a guesstimate on the capacity of the z access motor?

Current harvesting head comes in around 2kg could suppliment the UTM with three electromagnets, is Z access motor capable of 2.3kg?


#4

My guess is it would struggle with a 2.3kg payload, or it wouldn’t work at all. All of our tools thus far are very light weight (100g or so). The capacity of z-axis also varies based on installation factors. Poor stepper driver tuning, dirt, too tight of v-wheels, the cold, can all negatively affect performance.
