Greetings all; Several question mark below.
Those glass plates for my ender-3 Pro's build plate use have arrived, and I'm somewhat taken aback by the mass of a 230x230mm by 4mm piece of glass. This at least doubles, likely more, the weight the y motor has to manhandle, in my mind affecting the ballistics of its movement. No glass clips or instructions came with it although the glass was packed to survive a tactical nuke, So I'll raid the laundry room for some spring clothes pins. Plastic, lighter than the old wooden ones, but I stuck a couple on the front of the bed and the heat isn't bothering them. The stock Merlin driver has some adjustments for both acceleration and jerk. Accel is currently set at 500, sounds pretty instant to me and jerk is set at 8 but thats a new term for me and I have no idea of how a change to that effects the machine. Given the increased mass to move, is it even possible to keep the working velocities at the currently set values, or is there a way to determine what is optimum for this added mass it has to move? I'm assuming changes in the ballistics would have to be set in the x axis at the same time to keep it from bending corners. Or, would I be better off spending the sheckles for one of the improved 32 bit driver boards I see being offered? Power supply might come into play too as its only 24 volts now, which will effect its accel and ballistics envelope too. Discussion, educational/reference URL's all welcome. Thanks all.
