Gentemen,
I´ve recently built my first 3D Cartesian printer. I am using NEMA23 steppers connected to 3mm pitch lead screws, driven by pololu drivers, RAMPS1.4 board and Marlin fw V1.1.5.
Honestly, I´ve been searching for the answer for my problem for a while (perhaps I am not asking the correct question) therefore, I gave up and decided to ask the specialists.
During my first move trials, I saw that the motors were vibrating and not moving. After searching here and there, I found that the problem was related to the wiring. This was solved using arduino MEGA connected to the driver and directly to the motor, using a specific piece of code, just to find out the correct order of the wires.
Then, after everything was assembled, I tried to move X and/or Y just 10 mm to see how it goes but nothing happened, only the vibration. This was done using the display menu. Searching here and there, I decided to lower my speed setting (XY_feedrate) to 10 and vóila, both motors moved without problems despite the slowliness.
Downloaded Repetier, enabled the EEPROM in Marlin FW, got everyone talking to each other and still can not make the motors move faster then 10 mm/s, even using Repetier and changing the parameters from there.
The pololu drives were set to feed 2A to my motors, which is the phase current specified. I am using 12 Vdc.
Did anyone have a similar problem? Could you point me to the correct information on how to calibrate the speed etc?
I know it is a dumb question but so far I was not able to fix it.
The motors are moving the correct distance when instructed to do so. Another thing I noticed is that, according to the Marlin page, there are two feedrates for XY, one for moving and one for homing. Even when I home the axis to their parking positions, they still move very slowly.
Appreciate any light you can provide.
Regards,
Marcus
