Hi,
I have a project where i used a micro maestro to control 2 servos. Due to repeated problems with one of the servos i’ve replaced it with a stepper motor. For control i’m using a Tic T500, hooked up to the maestro via the RC connector. Below a summary of the hardware:
-Micro Maestro
-Tic T500
-Nema 17 Steppermotor (4V, rated current: 1,2A)
-Power supply (to the tic) 12V 2A
The stepper motor is functional in this setup. However, it tends to jitter (especialy near the end of a turn), also it appears to wander off the set end position. (When playing a sequence in a loop (maestro software) the end position seems to go progressively further off target.).
Possibly the jittering causes the wandering off target(?) Jittering occurs regardles of the speedsetting of the motor.
My knowledge of electronics is fairly basic, i love the comprehensive guides for the Pololu products. However, when it gets really technical i can get a little lost in the information overload… I’m hoping someone can help me sorting this out.
What i’d like to know is:
Is it possible to get a reliable system using a steppermotor controlled via RC signal (from a maestro)?
If so, what can i do to improve the performance? (settings?)
If not, is there another way to get the stepper to be more reliable (preferably using the existing hardware)?
Hope to be hearing, thanks in advance!
Best regards,
Hans
