I finally received and printed all the materials a few weeks ago.
When I started to build it, I had issues with the Art4 which was moving a lot due to slack but I found this and it fixed it perfectly. I would recommend to add it to the mod folder to be easier to find 😉
Regarding my issue, I have randoms homing failure. Is there any way to know more about the failure?
It seems to be on sometimes on Art2 and sometimes on Art4.
Basically, it looks for the 0 position, reach it and then stops with failure which is strange because it clearly detected it.
One more question about the current drawn, I have currently everything connected except the gripper.
I have a 12V 10A power supply. I measured the current drawn at the power supply and it is only 3A…
Which seems very weird, I have configured the drivers with the following formulas
for Art2 & 3 motors:
Vref = 8 * 0.1 * 0.4 = 0.32
for the others:
Vref = 8 * 0.1 * 1.3 = 1.04
Don’t you think it’s weird to have only 3A drawn?
