    Hi I'm trying to decrease the weight of the print carriage. I've printed the 1.1 version hot ends and am using my bigbox with a Bowden set up (currently a bigbox pro) now that I have moved the motor from the carriage I'm thinking I probably don't need the torque from the nema motor which moves the x axis. My question is if I have dual Bowden hot ends what would be a lighter replacement nema motor that would do the same job as the one I currently have?

    I think that's an interesting question, and if nobody is answering it, it may be that you're a pioneer!

    Good thing is that these motors are not super expensive so you could do some trial and error....

    Good idea. I am still building my dual. I'm having internal discussions about if I should go with two titans in hybrid or lighter direct motors. Anyways it would be lighter then the big original dual motors.

    Give it a go. Buy a couple of alternatives and report back :D

    It is possible, but if you change the motor of the x-axis, you would loose acceleration speed on that axis (because of the lower torque) and thus your prints will be slower.

    Its actually the jerk setting I'm trying to improve, I'm thinking if I can decrease the mass of the carriage then I can decrease my jerk values for x/y.

    OK. I thought you were talking about replacing the X-axis motor.

    Yes it is the X axis motor I'm wanting to change, to one with a lower mass version, however I'm having difficulty finding one with 400 steps per revolution AND with the detachable cable connection. Any suggestions?

    Don't get hung up on the connector issue...

    Two minutes with a soldering iron is a small price to pay for a breakthrough discovery! ;)
