I have troubles getting my motors running above 400 mm/minute.
I have modified my 5XC board to run full steps in order to get the steps/mm down to 320.
Whenever I try to run at higher speeds than 300 - 400 steps/mm my motors start rotating while accelerating, then stalls when speed gets above 400steps/mm and make a high pitched sound while running at the desired speed, finally the motor starts rotating again when the stepper driver decelerates.
To me it seems wierd that the speed is THAT low, but then again i am new in 3D printing.
Yes I am using 8mm - 1,25mm pitch leadscrews for all axes.
It is a homemade machine and it is my first build, so maybe using those leadscrews for X and Y axis is just a rookie mistake and this is the expected max speed with that setup.
I am now considering converting X and Y to be belt driven.
Do you know if that indeed is the max speed with this setup?
Any suggestions for proceeding with the current setup?
Yes, using leadscrews for a 3D printer, unless you know exactly what you are doing, is generally a mistake and leads to all kinds of problems, including those you are meeting.
Belts would be a much better idea here.
I will be changing to belts for X and Y.
The Z axis will remain driven by a standard 1,25 pitch leadscrew. But I suppose that is not gonna cause to much trouble since it never has to move rapidly.
Or is that a mistake again?
