Hi guys,
Thank you for all the informations, sorry we're late to answer but we were working a lot on our 3d printer, we're still experiencing some troubles, but nothing very disturbing.
@Catalin_RO thanks for all the clarifications on what cable you use and your explaination. We are currently working on changing the wiring of the printer to put some bigger shielded cable and ground everything the right way. As you said, using Nema23 is more than enough to move our gantry, and as you pointed we have more than enough torque, so for the next machine it will be open to amelioration on choosing better motors.
Again, thanks, that's very nice to see that people care about other's problems and respond very quickly !
All the best,
Team Trideo
