I have a hard time finding a good heavier duty servo that does not cost the price of a car. I looked into how to make one from a DC motor. There are some open source project about it: https://hackaday.io/project/9433-brushed-dc-servo-drive https://hackaday.io/project/9433-brushed-dc-servo-drive https://www.crowdsupply.com/citrus-cnc/tarocco https://www.crowdsupply.com/citrus-cnc/tarocco But for some reason, most projects I found do not use DC motors: https://www.kickstarter.com/projects/tropicallabs/mechaduino-powerful-open-source-industrial-servo-m https://www.kickstarter.com/projects/tropicallabs/mechaduino... https://odriverobotics.com/ https://odriverobotics.com/ If you ever find a good OSS servo, could you ping me?
