Thank you, the encoder is not connected to the dm556 but to an esp32 which records the pulses to give the position of the carriage and thus correct the errors.

@@hoyangvakei thanks for responding. Did you make any changes to the file? Can you send me an email?

@@fabienbois-wp9sg c'est une bonne question j'ai jamais fait le test de force. Sur la vidéo il est régler sur 10% de force et je le trouve déjà assez brutal.

the encoder is used to know the exact position of the carriage to correct errors and loss of nema.

looks like it is a nema 17 on the video

yes version 2 is still equipped with a nema 17, I have not changed controller I am still on TB6600 but I am thinking of switching to DM556.

@@hoyangvakei have you seen the tmc2160 oc by makerbase? its really great, i will use 3 of them on a cnc project that im making, they are super silent and capable of 4,2 amps rms if im not mistaken, the only possible drawback for the active pedal application is that they start the microstepping configuration on the 1/8 of step

Magnetic encoders are not a good idea for this project, because they tend to crash the esp32 because of the i2c communication and their calculation speed gives position errors on accelerations. I went with a mechanical encoder to solve the problem.

​@@hoyangvakei thanks for the answer!! Have you had any problem regarding the stepper motor rpm? Im asking because unlike a servo they tend to be weaker at high rpm rates

I use an ab encoder.

@@hoyangvakei Nice!! Im trying to make one similar to yours but will use a 12kgcm nema 23 with a magnetic encoder, i needed to ask you how i could make my own code to make it work

Merci à toi 👍

Salut c un choix le rail avec les tubes de chaque côté et non un rail par le dessous ?

@fabienbois-wp9sg oui c'est un choix, le tarif est plus intéressant qu'un rail à bille. Le système permet aussi de raidir toute l'installation.

@@glitchinthematrix9306 yes you are right, the noise comes from the motor controller which I replaced in the new version.

@@hoyangvakei which motor controller are you using now?

@@glitchinthematrix9306 i am interested in this too. Any chance for a video with the new sound/noise? im interested in building one for myself, but too much noise might be an issue for me.

@@sageone-mu6kt When the project is finished and functional, I will provide the code and plans on the Xsimulator.net site. I am currently working on a new version.

the first prototype works a nema17.

@@hoyangvakei servo? Does it have enough torque and speed?

@ValeriOS_3d_printing The Nema 17 is not very powerful, but the first tests are rather satisfactory, the pedal is responsive and has a good feeling, the only problem is the noise created by the Nema17 (crackling and grinding noise).

@@hoyangvakei ok thanks for the info. I was planning on using a 120w dc motor with an encoder instead of a stepper motor. Do you think it might work?

@ValeriOS_3d_printing yes I think it is possible but you will need an encoder with high precision. The advantage of stepper motors is the rotation by impulse which makes them very precise.
