After the replacement of the Farmduino board the setup is working so far but we seem tohave hit a snag during testing for the Z-axis.
It has no issues going down but if we set it to go up greater than 10mm per move, we will get a stall error and needs to unlock,
We have done the following based on the recommendations in the forum and also on the Farmbot online documentation:
Making sure the spacer for the z-axis is set properly so that the z-axis does not wobble,
Halfing the max speed for z-axis and doubling the accelerate distance
Spraying a z-axis leadscrew with a graphite lubricant to improve the grip.
After these steps we are still getting stalling when we try to bring up the z-axis for any lengths greater than 10mm (100mm or more)
Any insightsvto overcome this problem?
