I'll try to solve this keeping the A4988 drivers, modifying the design and trying to print the gears with other materials.
I gone use Microstep Driver ST-7128 from stepperonline My gears are printed with ABSPlus from Stratasys. (If you need some let me know) When I finished the robot I will give feedback I going to look to buildin a ventilation systeem into the second articulation to prevent the heating.
I'll be waiting for that awesome feedback!
I just pushed a new modification of the design, allowing the air-flow and the installation of 40mm fans. Before merging it to the main branch I have to test it.
Can't wait to see your solution!
Solved on dd6c5e3! Yay, the new design enable the air flow and refrigeration of the steppers. Now they don't melt the structure or gears, making possible the arm activity for a long period of time.
Closing this!
Steppers overheat causing printed gears deformation and malfunction of the arm. Possible causes:
